A published paper by

has been circulated to
Australian state au-
thorities for considera-
tion. If the formula is
adopted, the shorter
quarantine distances
are likely to be incor-
porated into domestic
trade agreements
within a year after fur-
ther individual consul-
tation. Shorter quar-
antine distances are
likely to decrease by

RESEARCH ON FRUIT FLY CONTROL IN SOUTH AFRICA

A combination of pro-

organophosphates
such as malathion has
been traditionally used
for fruit fly control in
citrus orchards in
South Africa. However
in January 2009, the

Science risk
The movement of
medflies within and
between agricultural
regions in South Africa
was investigated using
molecular genetic
approaches. By
sampling flies from
different geographic
locations and
documenting the genetic
variation and the amount
of gene flow between
populations, it was shown
that these flies are far
more genetically
homogeneous than
expected, even at
large spatial scales.

A behavioural study
has shown that female
fruit flies spent 90% of
their time on the sur-
rounding vegetation.
Based on that, a team
from CIRAD in Réu-
nion Island set itself a
target of zero pesticide
use on vegetable
crops. By planting
maize all around mar-
ket garden plots, there
is no need to treat against
vegetable flies, the main
pests on such crops. This
success story is the fruit
of several years' research
on agro-ecological man-
agement of horticultural
crops in Réunion, and will
serve to cut losses and
costs and above all en-
sure healthier crops.

The steering committee of TWWH has agreed at the Panama meeting
that the next group meeting will be organized in 2016, 4 years after the
8th meeting. No venue has yet been decided and the invitation to po-
tential hosts to submit proposals is open. If your organization is willing
to organize this meeting, please send your proposal to Pablo Liedo
([email protected]). The steering committee is expecting to make a
decision next year (2014), at the International Symposium on Fruit
Flies of Economic Importance to be held in Bangkok, Thailand.

FRUIT FLIES AT THE XII INTERNATIONAL CITRUS CONGRESS Beatriz Sabater-Muñoz, Francisco J. Beitia & Alberto Urbaneja Instituto Valenciano de Investigaciones Agrarias (IVIA)
The XII International Citrus Congress (ICC2012) took place last November (18-23) at the Valen-
cia Conference Centre (Valencia,
Spain). Organized by the Instituto
Valenciano de Investigaciones
Agrarias (IVIA), the Fundación de
la Comunidad Valenciana para la
investigación agroalimentaria
(Agroalimed) and the International
Citrus Society (ICS), the event
was chaired by Dr. Luis Navarro.
The ICC takes place every four
years and brings together resear-
chers, nurserymen, citrus specia-
lists and other people actively
working on citrus. 24 citrus enterprises and cooperatives participated as sponsors. More than
1200 delegates from 56 countries contribute with 720 scientific presentations. More..

Retirement - Dr Pedro Ros After 43 years working with fruit flies, next
April comes the time of my “official retire-
ment” from the Ministry of Agriculture.
The development of the Tephri Trap has been
one of my contributions to the Tephritid
workers community.
I will continue to be active, but in a private
capacity to Sorygar. Bye bye and thanks
to all those I knew during this time. Pedro Ros
