1. Executive Summary
Ento-Prise addressed two major livelihood challenges facing fast growing, urbanising LICs in Africa;
enhancing food and security and sanitary waste disposal. An over-arching research question was
could an improved approach to organic waste transformation through insect larvae and bio-fertiliser
co-production promote pro-poor employment opportunities in Ghana? Taking a highly
interdisciplinary biotechnical and value-chain approach, Ento-Prise aimed to support adaptive-
transition from a rural tradition of extensive low-input/output insect-based waste-remediation at
homestead level (natural mixed species ovi-position for free range poultry) to intensive peri-urban
monoculture of high-yielding black soldier fly (BSF: Hermetia illucens) capable of feeding on diverse
range of organic substrates. Results indicate greatest adoption potential in metropolitan peri-urban
settings integrating sanitary and soil fertility needs, co-location of high-volume low value substrate
inputs and demand for co-products by small-scale vegetable farmers and feed-lot livestock
(especially poultry) producers supplying local consumer demand for animal protein and vegetables

from a growing urban middle class. A study of BSF commercialization trends in China also confirmed
the validity of this approach whilst equatorial Ghana also has the advantage of year-round
production potential under ambient temperature conditions. Stakeholder perception surveys
indicated high levels of stated acceptance for use of co-products by small-holder farmers (including
women) and consumers of end-products. Rudimentary management systems for ‘green-wastes’
from open-air retail markets and supermarket distribution chains (see below) also indicated good
potential for adaptive incorporation into a putative BSF supply-chain.
Organic waste streams from a diverse range of sources (poultry manure, tilapia processing offal,
municipal and fruit and vegetable wastes were evaluated and the latter ‘green-waste’ identified as a
high potential substrate in terms of safety (heavy metal and bacterial contamination risk), availability
(in time and space), low opportunity-cost and BSF production performance. The resulting BSF co-
products; dried maggot meal (DMM) and biofertiliser were found to be equivalent or superior to
conventional inputs in on-station agronomy and poultry (Guinea fowl) nutrition trials in terms of
growth, yield and survival. Sex-reversal and survival rates of juvenile tilapia fed hormone treated
DMM were comparable with positive controls (hormone treated fishmeal and a commercial diet)
though increasing DMM inclusion depressed growth rates. Taken together, these results indicate
greatest potential for DMM inclusion in poultry diets, with DDM diets achieving up to 17% higher
growth compared to fish meal controls in two trial phases. In 3 phases of on-station agronomy trials
(GIDA) combination BSF biofertiliser (at 10t/ha) and inorganic fertilizer applications achieved up to
55% superior yield outcomes compared to the same inorganic fertilizer and local (poultry) manure
combinations; evaluated on a range of locally important short-cycle cash crops (especially shallots
and maize). Preliminary analyses also point to improved soil moisture and nutrient retention.
Life Cycle Analysis indicated CO2 emissions and global warming potential linked to BSFL production
(mainly originating from larvae themselves) was comparable or superior to levels which would be
produced if fruit waste was directly disposed of in land fill or composted. BSF biofertiliser and dried
maggot meal (DMM) also compared favourably against existing inputs evaluated in livestock-
nutrition and agronomy trials; especially when used for Guinea Fowl production, achieving up to
25% CHG reduction compared to tuna-fishmeal based diets. Research also confirmed ability of BSF
larvae to eliminate potentially pathogenic faecal bacterial contaminants detected in fresh fruit and
vegetable samples from open-air retail markets in Accra and Tamale.
Despite over-coming significant BSF production hurdles, including a biosecurity solution to
broodstock pre-pupae infection by parasitoid wasps, simple cost-benefit analysis presented only a
marginal case for small-holder adoption at the current-state of system development. Although
further research and development is still required, Ento-prise has taken other robust steps to
improve system productivity over the last year. This includes trials on improving white larvae/
substrate separation efficiency at optimal yield and nutrient quality points in the grow-out cycle i.e.
before a self-harvesting but less nutritionally optimum pre-pupae stage – in-turn determined
through comprehensive larval growth and macro/ micro-nutrient analyses trials in controlled
environment facilities (CEF) at the University of Stirling.

Results contributed to development of a BSF process manual for prospective adopters and five
short-videos (English/French) demonstrating step-wise production steps at the Ento-Prise BSF
facility, cost-benefit demonstration and others introducing the project and highlighting putative
value-chains in Accra (hosted on the project website, social media and you-tube. Training and
extension events were embedded in on-station agronomy trials and BSF production options/ use of
larvae meal as poultry dietary ingredient promoted by local partners at the Ghana National farmer’s
day in Dec 2015. The projects overarching goal of fostering small-holder adoption will be taken
forward by Ento-Prise partners ARI and CABI who will continue developing the prototype production
facility located on the ARI campus as an integral part of a 6 year follow-on Swiss funded (SDC and
SNFS) project ‘Sustainable Use of Insects to Improve Livestock Production and Food Security in
Smallholder Farms in West Africa’ (IFWA: http://www.r4d.ch/modules/food-security/insects-as-
feed). IFAW combines 3yrs of primary research followed by 3 years of technology adoption effort
with small-holders including livestock and aquaculture BSF larvae end-users.
2. Relevance of the Project
Explain the relevance of the project. Did your RCF project remain relevant in the context in which
you are working? Please explain what you have done to ensure that the interventions represented
in the logframe continued to respond to the needs of the research aims.
Ento-Prise addressed two major livelihood challenges facing fast growing, urbanising LICs in Africa;
enhancing food and security and sanitary waste disposal. An over-arching research question was
can an improved approach to organic waste transformation through (black soldier fly: BSF) larvae
and bio-fertiliser production promote pro-poor employment opportunities in Ghana? Building on
earlier experimental work demonstrating technical potential at experimental scale and taking a
value-chain approach, the project aimed to assess and support potential for commercial-scale
maggot production and utilization of its products considering local socio-economic and resource
opportunities and constraints.
The project took a highly adaptive approach to support transition from a rural tradition of
extensive low-input/output insect-based waste-remediation at homestead level (using natural
mixed species ovi-position for free range poultry) to intensive peri-urban monoculture of high-
yielding black soldier fly capable of feeding on diverse range of organic substrates. This
intensification approach has greatest economic justification in peri-urban settings where there is
co-location of input supply (organic-waste) and demand for co-products (BSF larvae and bio-
fertiliser). The emergence of intensive feed-lot livestock sectors to meet demand for animal
protein from a growing middle class is a feature of all Ghana’s metropolitan areas including Accra,
Kumasi and Tamale (i.e. with densely populated urban cores and less-populated surrounding
territories). Intensive feed-lot poultry (layer and broiler) is common to all these cities, whilst there
has been a particularly rapid growth of cage-tilapia farming on the Volta Reservoir in Accra’s
hinterland. Operating within highly competitive globalized markets, the future economic
sustainability of these sectors will to varying degrees depend on availability of quality local
ingredients for formulation of nutritionally complete diets. Meanwhile there is also a need for
organic fertilizer to augment yields and counter decreasing soil fertility by peri-urban small-holder

fruit and vegetable farmers supplying urban markets. In this respect, strategic co-location of BSF
production is particularly important given the higher volume/ lower unit value of BSF biofertiliser
i.e. compared to DMM.
Work Package (WP) activities presented in the description of work and as logframe interventions
were designed to fulfill three development objectives (Outputs):
Output 1: Commercial-scale Insect production system and co-products evaluated for economic
performance
Significant progress (summarised below) was made against all outputs, however simple cost-
benefit analyses pointed to limited economic justification for adoption of BSF production by small-
holders at the current state of system development. The analysis based on the projects pilot BSF
system (ARI campus) producing 0.76t DMM and 9t biofertiliser in five 2mx2m concrete bays over
12 months (with output prices based on best-case agronomy and livestock trial outcomes – see
below) indicated annual profit of only USD 248 and a 19yr pay-back on initial buildings/ equipment
capital outlay. Assuming broadly linear scale-economies scaling up to 15 bays, with increased
building size, broodstock cage capacity for egg production - outputs increase to 2.27t DMM and 27t
of biofertiliser per year, increasing annual profit to USD 1907 and reducing fixed capital payback
time to 4 years. Both these estimates also exclude labour costs; assuming the small-scale adopter
would operate the site on a half and full-time basis for the two scale scales, taking income from the
profit generated (c.f. with an average Accra peri-urban agriculture salary of USD 1920). These
findings, based on optimal and sustained production outcomes, point to need for further
biotechnical research and development to enhance productivity i.e. beyond simple up-scaling to
justify commercial adoption. It is pertinent to note here that at current productivity levels, the
DMM and biofertiliser outputs contribute an approximately even share of farm-gate revenue in
the above example (though biofertiliser transport costs will be considerably higher).
The model also assumes accessible markets and reliable demand for each of the products at prices
equal or lower than their equivalents (e.g. locally available chicken manure fertiliser and good
quality dried fish meal). The dual production nature of the system is likely to provide some
resilience to market volatility as demand for two co-products are likely to be relatively de-coupled.
Market options and scale-economies also expand with production up-scaling, although the
relatively good keeping properties of dried maggot meal and (especially) biofertiliser do to some
extent lend themselves to longer stock-piling periods at lower production scales. Conversely,
greater logistical challenge in matching supply and demand for more perishable white-larvae as a
live-feed for livestock (especially poultry) would be more suited to small-scale on-farm co-located
production (this model has proved especially popular with small-holder poultry producers in China.
Understandably, more risk-averse small-holders engaged during the project were generally
reluctant to collaborate on a pre-commercial model such as this, preferring to wait for
development of a more fully proven ‘turn-key’ system.
For this reason, with prior agreement of AgriTT management the original final project mile stone
(MS6) which was:
Ento-Prise: COMMERCIAL SCALE INSECT-BASED TRANSFORMATION OF ORGANIC WASTES TO
BENEFIT SMALLHOLDER FARMERS IN GHANA
AgriTT Final Report Form – Research Challenge Fund Projects 7
‘By December 2015 to have 15 small to mid-scale adopters (10 female, 5 male) who had taken up
Black Soldier Fly larvae rearing on a stand-alone commercial basis’
was modified to:
‘Efficacy of BSF co-products in livestock nutrition and agronomy trials demonstrated against
prevailing production practices and results extended to small-holder farmers through training and
extension events’.
With respect to the original MS6, Ento-Prise partners ARI and CABI will continue to build on project
findings developing the prototype production facility located on the ARI campus as an integral part
of a 6 year follow-on Swiss funded (SDC and SNFS) project ‘Sustainable Use of Insects to Improve
Livestock Production and Food Security in Smallholder Farms in West Africa’ (IFWA:
http://www.r4d.ch/modules/food-security/insects-as-feed). IFAW combines 3yrs of primary
research followed by 3 years of technology adoption effort with small-holders including livestock
and aquaculture BSF larvae end-users. A further potential production bottleneck requiring further
research and communicated with IFWA relates to the observed variability in broodstock/ egg
output linked to potentially inter-acting environmental and genotypic factors (for example we
suspect sex-ratios may be determined in part by egg incubation temperature).
Output 2: Commercial-scale Insect production and biofertiliser evaluated for public health,
environmental performance and social acceptance
Organic waste streams from a diverse range of sources (poultry manure, tilapia processing offal,
municipal and fruit and vegetable ‘green market’ wastes) were evaluated and the latter green
waste identified as a high potential substrate in terms of their safety, availability, opportunity cost
and BSF production performance.
The resulting BSF co-products; dried maggot meal (DMM) and biofertiliser were found to be
equivalent or superior to conventional inputs in on-station agronomy and poultry (Guinea fowl)
nutrition trials in terms of growth, yield and survival. Sex-reversal and survival rates of juvenile
tilapia fed hormone treated DMM were comparable with positive controls (hormone treated
fishmeal and a commercial diet) though increasing DMM inclusion depressed growth rates. Taken
together, these results indicate greatest potential for DMM inclusion in poultry diets, with DDM
diets achieving up to 17% higher growth compared to fish meal controls in two trial phases.
In 3 phases of on-station agronomy trials (GIDA) combination BSF biofertiliser (at 10t/ha) and
inorganic fertilizer applications were found to give up to 55% superior yield outcomes compared to
inorganic fertilizer application for a range of locally important short-cycle cash crops (especially
shallots and maize). When applied alone, the bio-fertiliser also compared favourably with local
organic (poultry) manure and inorganic fertilizer combinations. Preliminary analyses also point to
improved soil moisture and nutrient retention.
Stakeholder perception surveys also indicate high levels of stated acceptance for use of co-
products by small-holder farmers (including women) and consumers of end-products. Analysis of
existing waste management of green wastes from retail markets and supermarket distribution
networks also indicates good potential for adaptive incorporation into a putative BSF supply-chain.

Results point to greatest adoption potential in peri-urban settings integrating sanitary and soil
fertility needs, co-location of high-volume low value substrate inputs and demand for co-products
by small-scale vegetable farmers and feed-lot (poultry) livestock producers.
On-station (ARI) BSF broodstock/egg and larvae growth performance trials and matched trials in
controlled environment facilities (CEF: UoS) contributed to determination of high-potential (locally-
available) production substrates, to address biosecurity issues linked to broodstock infection by
parasitoid wasps and confirmed ability of BSF larvae to eliminate potentially pathogenic faecal
bacterial contaminants detected in fresh fruit and vegetable samples from open-air retail markets
in Accra and Tamale. Life Cycle Analysis assessments indicated that global warming potential linked
to CO2 emissions from BSFL production (mainly originating from the larvae themselves) was
comparable or superior to levels which would be produced if fruit waste was directly disposed of in
land fill or composted. DMM also compares favourably against emissions for tuna by-product fish
meal for which it substituted in livestock nutrition trials; especially when used for Guinea Fowl
production which achieving up to 25% CHG reduction compared to fishmeal based diets. DMM
performed more poorly against land (with BSF production in low-level bays) and water-use impact
indicators. The former by may be more limiting at larger production-scales in peri-urban locations.
Differences between bio-fertiliser and inorganic fertilizer applications were less marked due
relatively high contribution of direct land and water use compared to upstream production factors.

MS1 Waste streams for insect-based transformation mapped and parameterised
A range of tasks (across WPs 2,3 & 4) covering stakeholder
analysis, substrate availability/ opportunity cost assessments
( contaminants assessments, BSF larval growth and
nutritional quality trials) contributed to the screening of a
wide range of candidate substrates (including poultry and
pig manures, tilapia processing offal, municipal organic
waste, fruit and vegetable waste from processing and
informal and formal market sectors) and final selection of
green market waste reliably sourced from open air retail
markets as ‘high potential substrates’ for up-scaled
production to supply agronomy and livestock nutrition trials
(see below).
A generalised indicator-based decision tree approach for
substrate selection was also developed (summarised in
Annex 1a).
A tilapia-fry BSF nutrition and sex reversal efficiency trial
(see below) was accompanied by a ‘needs-analysis’ survey of
10 tilapia hatchery managers/ owners in the lower Volta
area.
Substrate and co-products contaminants analysis are documented in Annex 4C (macronutrients and heavy metals) and Annex 4D (microbial contaminants)
Annex 2A, 2B and 2C document stakeholder (consumer and farmer) attitudes to insect derived products and participation in BSF value-chain activities. A student MSc thesis documenting exploratory engagement with value-chain stakeholders (M4-7) is included in Annex 2D.
A summary of the tilapia hatchery ‘needs analysis’ interviews are included in Annex 3B (pending finalisation of a full-report)
1.2 Insect-rearing technology adapted to local environmental and socio-economic conditions
MS1 Models with commercial potential identified for trials
A highly modular stacked (22L) tray based BSF system
design, constructed at the ARI Adenta research station,
ideally lent itself to broodstock amplification and substrate
evaluation trials at the outset of the project (broodstock tray
contents were transferred into 3 ramped concrete bays for
self-harvesting) .
Once steady state egg production was reasonably assured
and ‘high potential’ substrates determined (i.e. green
market waste) attention shifted to up-scaling grow-out
production in five specially constructed 2mx2m (220L
capacity) enclosed concrete bays during the second project
year. Simple-cost benefit analysis (Annexe 2c) pointed to a
need for further productivity gains to encourage small-
holder adoption (see section 2).
This work also involved development of an effective

1.3 Insect co-products produced that can be as cost effective or superior to commercially available controls
MS1 Economic performance of co-products evaluated against commercial alternatives
Three livestock nutrition trials were undertaken evaluating
effects of different dietary substitution rates of BSF dried
maggot meal on production performance of Guinea fowl (GF
– 2 trials) and tilapia (1 trial). All trials were based on simple
direct substation of full DMM for fish meal (FM) i.e. rather
more complex formulation against species macro-nutrient
reference requirements. This was based on a need to avoid
the additional post-harvest processing complexity and cost
involved in producing a defatted maggot meal.
Two GF juvenile (keet) and on-grower trial phases conducted
‘on-station’ (ARI campus) demonstrated highly encouraging
growth gains (up to 17%) positively correlated with DDM
inclusion. The second (shorter; keet only) trial confirmed
reproducibility of phase 1 results.
Conversely the tilapia trial (in partnership with commercial
cage farmer Tropo Farms at their hatchery site)
demonstrated a negative correlation between juvenile
‘swim-up’ fry growth and DDM inclusion compared to
positive controls (a commercial starter diet and pure fish
meal). However, no significant difference was observed
between phenotypic sex-reversal rates (95-99%) - the
primary purpose of the trial; based on dietary inclusion of

the 17 α-methyltestosterone hormone).
The large GF growth ‘effect-size’ coupled with the low DMM
inclusion rate required to achieve it (i.e. around 6%
compared to typical inclusion of 10% FM in tilapia grower
diets) indicate a comparative advantage for the use-of scaled
up BSF production for GF and poultry grow-out (partially
offset by higher farm-gate prices for tilapia). Further
research is required on performance of defatted-larvae meal
and lipids in formulated tilapia diets targeting different life
stages. Small-scale ‘on-farm’ BSF production also has
potential for hatchery owners to ‘supervise’ quality; high
variability in fish-meal batch quality being recognised as an
important source of variability in sex reversal efficiency in
other tilapia producing countries.
Three iterative phases of ‘on-station’ agronomy trials lead by
GIDA were completed evaluating the performance (yield,
soil fertility and moisture retention capacity) of BSF
biofertilisers (composted BSF substrate residues) on a range
of cash crops commonly cultivated by small-scale peri-urban
farmers. Results demonstrated good biotechnical promise
for composted BSF frass as a bio-fertiliser – notably for
important food-staple maize; achieving equivalent yield
outcomes compared to combined NPK inorganic and organic
(poultry manure) applications reflecting current practice.
The BSF production cost-benefit model summarised in
section 2 is based on cost-equivalence between the best
performing BSF treatments and these alternatives.

production inputs (see indicator 1.3)
As it was not practicable to measure gaseous emissions
under field conditions in Ghana, measurement was included
as part of a wider comprehensive assessment of BSF growth
and nutritional quality under controlled temperature and
humidity conditions at the University of Stirling. Three
substrates were evaluated: fish (salmon) processing offal,
broiler poultry manure, and a high-potential’ fruit and veg
substrate mix analogous to the market wastes used in
Ghana.
MS2 Life cycle impacts of insect and conventional waste-stream remediation of target substrates quantified
Secondary (Eco-Invent) and primary inventory data
described above (inc. final agronomy and livestock trials)
was been used to compare environmental impacts of BSF co-
product production and application against existing
commercial production practices. Assessments indicated
global warming potential linked to CO2 emissions from BSFL
production (mainly from the larvae themselves) was
comparable or superior to levels which would be produced if
fruit waste was directly disposed of in land fill or composted.
DMM also compares favourably against emissions for tuna
by-product fish meal for which it substituted in livestock
nutrition trials; especially when used for Guinea Fowl
production; achieving up to 25% CHG reduction compared to
fishmeal based diets. DMM performed more poorly against
land (with BSF production in low-level bays) and water-use
impact indicators. The former by may be more limiting at
larger production-scales in peri-urban locations. Differences
between bio-fertiliser and inorganic fertilizer applications
were less marked due relatively high contribution of direct
land and water use compared to upstream production
factors.

ultimately contributed to this objective. Analysis of brewery
and fish feed waste, chicken manure and oil-extracted tilapia
offal substrate combinations, agronomy trial soils and dried
larvae for heavy metals (Zn, Pb, Cd, Cu, Ni) indicated low-risk
of bioaccumulation through bio-fertiliser application, or in
DMM. Bacteriological analyses using selective agars
indicated high levels of potentially pathogenic faecal
indicator organisms (FIO) on a range of fruit and vegetables
sourced from small-holder vendors in open air retail
markets, but not from the same products sourced from
supermarkets. Analysis of BSF larvae gut contents raised on
the high-risk substrates confirmed the ability to ‘clear’
pathogenic species in their digestive tracts.

and UoS CEF trials - GIDA, UoS]
11. Lessons for BSF commercialisation in emerging
economies based on case-studies from China and
Ghana (UoS, SoU, ARI)
B. Explain factors that contributed positively to progress in your research project
1. Commitment of co-researchers responsible for coordinating pilot BSF larvae production and co-
product agronomy and livestock nutrition evaluation trials at the GIDA and ARI research stations
and commercial aquaculture partner.
2. Regular mentoring visits to by UoS project staff and longer term placement of interns and
research students (MSc and PhD) to support collaboration with local partners in Ghana.
3. Collaboration with linked EU-FP7 ProteInsect project; in particular training of Ento-Prise staff on
basic broodstock/ egg production techniques attuned to local environmental conditions. This and
immediate access to BSF production waste for biofertiliser composting, gave Ento-Prise a
significant head start in implementing its pilot BSF grow-out system and implementation of 3
separate agronomy trial phases within a relatively short-two year project cycle.
C. List challenges in your work and how they have been addressed
1. Logistical problems delaying construction of some BSF production system elements and
variability in egg production rates which had knock-on effects on ability stockpiling of maggot
meal. Whilst all planned trial work was implemented This pushed the single aquaculture nutrition
trial into the last quarter of the project.
2. Sub-optimal experimental and sample design in early phase trial and substrate collection. Early
problems were corrected in later agronomy and nutrition trial phases. In particular Dr. Richard
Quilliam (UoS) offered GIDA staff expert advice on the design of a 3rd round of agronomy trials –
which we expect will contribute to a peer-review journal output.
3. Progress toward over-coming constraints for small-holder adoption of BSF production
technology would have been enhanced through more truly collaborative multiple iterative action-
research cycles with potential end-users. Unfortunately such a strategy was constrained by the
relatively short 2-year duration of the project. However we anticipate that Ento-Prise findings will
strengthen such an approach in the follow-on CABI/ ARI IFWA project.
4. Assessing the achievements of trilateral cooperation
A. Describe how the trilateral partnership worked for this RCF project.
The partnership generally worked well with the linkage to EU FP7 ProteInsect project supporting
transfer of existing knowledge from China for its adaptive co-development by partners in Ghana.
B. What was the expected role of each of the trilateral partners?

BENEFIT SMALLHOLDER FARMERS IN GHANA
AgriTT Final Report Form – Research Challenge Fund Projects 16
Based on experience in insect (fly) rearing, Huazhong Agricultural University (HZAU) primary roles
were to contribute expertise for the waste stream nutrients and contaminants assessment (WP2)
and design and adaptation of BSF production facilities (WP3). The Animal Research Institute (ARI)
of the Government Council for Scientific and Industrial Research (CSIR) was responsible for
managing construction and running of the insect production units at their Ashaiman research
station with CABI support. ARI was expected to lead on nutrient analysis of BSF substrate inputs
and co-products and HZAU on health hazards analysis (biological and contaminant risks) of the
same samples. The Ghana Irrigation Development Authority (GIDA) was responsible for designing
and implementing bio-fertiliser trials at the Ashaiman Irrigation Scheme. Similarly ARI was
responsible for running Guinea fowl maggot meal nutrition trials at their Ashaiman facility, UoS
and CABI for coordinating tilapia nutrition (sex-reversal) trial with commercial partner Tropo
Farm. CABI was also expected to support dissemination activities consistent with its core
agricultural knowledge management mission and to provide a coherent follow-on ‘exit-strategy’
for practical application of Ento-Prise research outcomes linked to its Insects for West Africa
(IFWA) project.
C. What was the actual experience?
Expectations against assigned roles were generally well met. HZAU were respectively more and
less comfortable with the biotechnical and commercialisation aspects of the project.
Consequently to fill a key knowledge gap Dr. Wenbo Zhang of Shanghai Ocean University was
commissioned to conduct an in-depth review of the commercial status of BSF value-chains in
China in the final months of the project. GIDA and ARI performed especially well within their core
agronomy and livestock nutrition technical competencies, also adapting well to collaborative
challenges imposed by the projects highly inter-disciplinary approach.
D.
a) For Theme A projects: what was the Critical Agricultural Technology from China – how was
it tested and what was achieved?
b) For Theme B projects on value chains: how did the trilateral partnership contribute to value
chain development?
c) For Theme C projects: how did the trilateral partnership contribute to enhanced information
and knowledge flows?
Ento-Prise was a theme A project, although it also adopted an explicit value-chain approach to
evaluate commercialisation potentials. Chinese technology transfer on BSF production techniques
operated primarily through linked ProteInsect project (see above) in which both HZAU and Stirling
were partners.
E. How would you score the project, if looking only at its success in terms of trilateral
cooperation (1-5, where 1 is low, 5 is high)?

F. What lessons are there for future trilateral cooperation initiatives based on the experience
of this RCF project?
Effective collaboration requires close and sustained cooperation with partners to build shared
goals and trust. Representatives of UoS, 2 African partner institutions (GIDA and ARI) and HZAU
jointly participated in field visits to BSF commercial enterprises in Guangzhou after the mid-term
AgriTT progress meeting in Beijing. This proved a very successful team building exercise;
unfortunately it was not possible to coordinate a joint visit to Ghana by UoS and HZAU partners;
HZAU being able to visit Ghana only once early in the project.
5. Impact of the RCF Project
What has been learnt from your research work?
Key research findings are as follows:
- BSF bio-fertliser and maggot meal products demonstrated equivalent or superior production performance to conventional inputs in agronomy and Guinea fowl nutrition trials. Differential outcomes between Guinea fowl and aquaculture nutrition trials point to a comparative advantage for the former based on lower grow-out inclusion requirements and 17% faster growth compared to positive controls using simple substitution of whole maggot meal i.e. with no requirement for additional post-harvest processing (de-fatting) or complex formulation based on proximate analyses.
- Commercially viable aquaculture application is likely to require de-fatting of BSF larvae and balanced inclusion of the resulting BSF protein and lipids in tilapia diets. There may also be more niche application for assured quality locally produced BSF meal and lipid as fry and broodstock dietary ingredients.
- Green-market waste were identified as high potential BSF substrates based on contamination risks, opportunity-cost, seasonal and spatial availability, CHG emission profiles and BSF growth and yield assessments
- Stakeholder analysis indicates a generally highly positive attitude to potential participation in putative BSF production supply chains and consumer acceptance of plant and livestock products produced using BSF co-products.
- Commercial potential for BSF production is likely to be greatest in peri-urban areas with co-located input-output supply and demand with associated sanitation benefits.
- Simple cost-benefit analysis indicates a need for further productivity gains beyond simple linear up-scaling to justify adoption by small-holders. These might be linked to more efficient automated white larvae separation (Annex 5C) and strategic use of heating to optimise growth during early larval developmental stages.

How are the results from your project being disseminated?
Dissemination activities linked to the revised MS6 (and logframe output 3) include farmer training
and extension activities integrated in agronomy and livestock trials. Ghana and UoS production
trial findings have been incorporated in our ‘living process manual’ available for download from
the project website (http://www.stir.ac.uk/ento-prise/resources/).
Linked to the above, a series of five audio-visual presentations BSF value chains, production
techniques and cost benefit analysis have been completed and posted on the project website and
you-tube (see section 3 for web-links).
Project intern Jesse Willems gave two Ento-Prise presentations at a Newton-IUCAP workshop
‘Insect Meal: An Ocean Of Opportunities’ at the Crops for the Future Research Centre (CFF)
Headquarters, Kuala Lumpur, 9th March 2016 (i) Technical requirements for the breeding and
rearing of the Black Soldier Fly larvae, by Jesse Willems, University of Stirling, Scotland (ii) The Use
of Insects in Animal Feed – The Regulatory Position, by Jesse Willems, University of Stirling,
Scotland. Both presentation have been added to the project website and an additional ‘regulatory
status’ report developed from the second presentation (Appendi x ??).
Further details of these and other dissemination activities including staff blogs, social media
postings and press release are detailed in Annex 1A. The same Annex lists some of the individuals
who have benefitted directly from training and collaboration on the Ento-Prise project.
In what ways is uptake / wider replication of your results from your project being taken forward?
By your organization
PhD student Pierre Olivier Maquart will continue to build on Ento-Prise work; further validating
and extending findings on BSF substrate performance in controlled environmental facilities at the
University of Stirling and further aquaculture trials with a commercial partner (‘Namsai Farms’
producing sex-reversed tilapia Juveniles) in Thailand.
Other research bodies
Project partners CABI and ARI will build Ento-prise findings as part of the 6yr IFWA project (see
above).
The farming community
Ento-Prise agronomy results have also been disseminated to waste-disposal and sanitation
academy (K-AISWAM) company Zoomlion who are actively engaged in trials evaluating
performance of market-waste-based composts with small-holder farmer collectives around
Tamale.
Private sector business
One of Ghana’s largest supermarket chains has expressed interested in post project collaboration
on establishing its own pilot BSF recycling facility to remediate substantial waste in the fruit and
veg packing part of its supply chain.
Ento-Prise: COMMERCIAL SCALE INSECT-BASED TRANSFORMATION OF ORGANIC WASTES TO

Namsai Farms Thailand (see above) also has a commercial interest in cooperating on production
standardization for optimization of DMM of nutritional quality for juvenile tilapia sex-reversal. Lack
of consistent assured quality in third-party fish meal supplies is perceived as important
contributory factor for residual variability in sex-reversal rates.
6. Ensuring Value for Money
Economy: What has been done over the project period to buy and employ inputs at an optimum
value-for-money price (DFID considers inputs to include: staff, consultants, raw materials and
capital to produce outputs)? In other words, what has the project done to drive down costs while
maintaining the required standards of quality? Include references to the use of any relevant unit
cost benchmarks.
The project recruited one short-term consultant to fill a knowledge gap that could not otherwise
be filled in China (see Annex 5A report on the commercial status of BSF value-chains in China).
In addition two international interns were recruited over the course of the project support
partners in the implementation of BSF production, stakeholder assessment and dissemination
work-streams in Ghana at very low financial cost to the project. Regular visits by UoS staff (at
least 3x per year) were used to assess and support progress and ensure implementation was to
the highest standard within the practical constraints on the ground.
Efficiency: How have you ensured that resources (inputs) have been used efficiently to maximise
the results achieved? Include references to the use of any relevant cost comparisons
(benchmarks) at the output level (e.g. standard training cost per trainee); and any efficiencies
gained from working in collaboration with others.
A week-long introductory training programme on BSF production techniques was provided for 5
ARI research staff involved in WP3 - ‘In-house’ through the linked FP7 ProteInsect project at their
experimental production facility (close to the GIDA Ashaiman research station).
Effectiveness: To what extent do you consider the project to be effective in bringing about the
anticipated changes for target groups? How well are the outputs of the project working towards
the achievement of the outcome?

BENEFIT SMALLHOLDER FARMERS IN GHANA
AgriTT Final Report Form – Research Challenge Fund Projects 20
The project made considerable progress in identifying and overcoming researchable constraints
to commercial BSF production under local conditions. However outstanding bottlenecks
(requiring further R&D effort) meant a production model sufficiently profitable to justify small-
holder adoption could not be developed within the project period. However the project did
identify good biotechnical potential for BSF co-product utilization, disseminated this knowledge
to small-scale peri-urban farmers (consistent with a revised final MS6) and devised an exit
strategy which follow-on research project (IFAW) which conduct research in the deficit areas to
support future small-holder adoption.
Are there multiplier effects from this project? E.g. potential for leveraging additional funds;
longer term or larger scale implementation; or replication of approaches and results? Where
additional funds have already been secured, how have they been used to enhance delivery?
Project findings were used leverage additional financial support for entomologist Pierre Olivier
Maquart to pursue further research that will contribute to completion of a PhD program at the
University of Stirling. The work which will focus on further improving BSF production efficiency
and aquaculture nutrition application (in Thailand) will benefit from €10,000 support from feed-
supplements company DSM Nutritional Products Ltd and £5,000 from the EU-FP7 ProteInsect
project with its overlapping research aims.

Indicator 1: Commercial scale insect-based transformation of waste adopted by small and medium
enterprises (SME) in Ghana. Milestone: Adoption by 4 SMEs
Revised linked to project MS6 (justification in section 2). Further research is required to enhance
and assure stability of BSF larval yields for increased labour productivity to improve economic
justification for small-holder adoption (see Section 2).
Indicator 2: Insect-based biofertlisers and feeds utilised by small-holder (vegetable and backyard
poultry/ farmers) farmers, especially women in Ghana. Milestone: Adoption by 15 small holders (5
M, 10 F)
Revised linked to project MS6 (justification in section 2). Good biotechnical potential (see above)
and positive stakeholder attitudes were demonstrated – but small-holder adoption remains
constrained by higher costs of biofertiliser compared to conventional inputs at the current state of

A comprehensive mix of inter-disciplinary tasks (across WPs 2, 3 & 4) were successfully completed,
ultimately contributing to a BSF production cost-benefit analysis. These included stakeholder
analysis, substrate availability/ opportunity cost assessments ( contaminants assessments, BSF larval
growth and nutritional quality trials contributed to the screening of a wide range of candidate
substrates (including poultry and pig manures, tilapia processing offal, municipal organic waste,
fruit and vegetable waste from processing and informal and formal market sectors), final selection
of green market wastes reliably sourced from open air retail markets as high potential substrates.

(add extra rows if required).
Indicator 1.1: At least 3 high-potential waste streams shortlisted & procurement agreements
finalised with suppliers. Milestone: Waste streams for insect-based transformation mapped and
parametised
High potential substrates were identified based on a range of biotechnical and socio-economic
criteria (Section 3) and a generalised indicator-based decision tree approach for substrate selection
was also developed for wider application (summarised in Annex 1a).
Indicator 1.2: Insect-rearing technology adapted to local environmental and socio-economic
conditions. Milestones: (i) Models with commercial potential identified for trials (ii) Maggot
production is operational and parameterized
Both MS achieved – see narratives in Section 3.
A considerable body of additional research on BSF production performance was carried out under
controlled environmental conditions in CEF at the University of Stirling during the final reporting
period. This included a (i) second iteration of (scheduled) gaseous emissions work, (ii) a
comprehensive assessment of BSF larval growth and yield performance at a range of fixed
Ento-Prise: COMMERCIAL SCALE INSECT-BASED TRANSFORMATION OF ORGANIC WASTES TO
BENEFIT SMALLHOLDER FARMERS IN GHANA
AgriTT Final Report Form – Research Challenge Fund Projects 23
temperatures (& humidity) from 25-39oC for construction of a ‘degree-day’ (DD) production model
(iii) a comprehensive macro and micro nutrient profile of BSF larvae (& substrates) along the DD
growth-curves and (iv) a fourth round of BSF biofertiliser agronomy trials on onions in pots.
Items (i), (ii) and (iii) together provide a basis for optimised production scheduling based on growth,
nutrition and environmental performance. The trials also provided further insight into simple steps
for assessment of egg viability (based on ‘eyeing’), substrate moisture requirements, & larval weight
length ratios – all of which contribute to husbandry recommendations in the BSF process manual.
Indicator 1.3: Insect co-products produced that can be as cost effective or superior to commercially
available controls. Milestone: Economic performance of co-products evaluated against commercial
alternatives
Achieved in 3 phases of BSF biofertiliser agronomy trials and 3 BSF larvae livestock nutrition trials -
See narratives in section 3.
As only 3 trials (1 agronomy and 2 livestock) trials were envisaged within the 2yr project-period; 6
in-country trials represents significant additionality. This was facilitated through training on pilot BSF
production techniques and early access to BSF biofertiliser through the linked EU-FP7 ProteInsect
project during the first months of the project.
A further, a fourth round of agronomy trials conducted in controlled environmental facilities at
Stirling will give further insight into the effects of BSF biofertiliser on soil fertility as well as crop
(onion) yield (results of this, the 3rd phase of GIDA trials and BSF stakeholder perceptions work in
Ghana will contribute to a high quality peer-reviewed journal article.

impacts) to international open-access peer-reviewed journals.
Analyses are being finalised and papers are in different draft stages in each of these 3 subject areas.
A full list of potentially up to 10 co-authored papers is given in section 3.
8. Other matters
This section is open and allows you to draw the attention of the PMO or DFID to any matter in relation to your grant or the project that you wish to identify.
A great deal of activity including one agronomy, two livestock nutrition trials, value chain
stakeholder perceptions survey s, multiple dissemination activities in Ghana and BSF larvae
temperature growth, nutritional quality and gaseous emissions trials in controlled environment
facilities (Stirling) was concentrated in the final reporting period. As most of these activities were
only completed in February and early March2016, further in-depth analysis of some results is
ongoing (particularly for BSF larval macro and micro nutrient assays and a soil fertility and yield
assessments for bio-fertiliser trials including a final CEF onion agronomy trial). Journal submission
of planned co-authored peer reviewed articles associated with these activities will inevitably fall
out with the funded project period.
