Brinjal (Solanum melongena L.) is also known
as Aubergine or Eggplant is a solanaceous
member which is native to India and is considered
as one of the top ten vegetables in the world
(Srinivasan, 2009). Among the insect pests shoot
and fruit borer Leucinodes orbonalis (Guenee),
is considered to have economic importance. It
causes serious damage especially during the
fruiting stage and inflicts yield loss as high as 85–
90% (Patnaik 2000; Misra 2008; Jagginavar et
al. 2009).
This pest is widely distributed all over
India. Farmers rely exclusively on the application
of chemical insecticides to combat FSB, which
has resulted in a tremendous misuse of pesticides
in an attempt to produce damage-free marketable
fruits. Despite intensive insecticide applications,
the pest cannot be controlled due to its resistance
to commonly used pesticides. Therefore, the IPM
with conventional nonchemical methods of pest
control as components is thought to avert the risk
of pesticide and make the IPM more farmers’
and eco- friendly.
The moths are medium sized . Its wing
expanse is 22-26 mm. The wings are whitish with
large brown or black patches on the dorsum of
the thorax and abdomen. Its wings are white with

a bluish or pinkish tinge . Full grown larvae is
light pink measuring about 12 mm long and
covered with sparsely distributed hairs all over
the body. Pupates is a tough silken cocoon on
the plant itself. Entire life cycle is completed in 3-
6 weeks. There are five overlapping generation
in a year.
The pest is active throughout the year at
places having moderate climate but its activity is
adversely affected by severe cold. About 250 eggs
are laid by a single female on ventral surface of
the leaves, shoots, flower buds and occasionally
on fruits. Incubation period is 3-5 days, larvae
become full grown in 7-13 days. The full grown
larvae comes out and pupation takes place in boat
shaped cocoon on the plant itself. The pupal

period lasts about 7-10 days .Adults live for 2-3
days.
Infests the crop both in vegetative and
fruiting stage of the plant. In young plants, the
caterpillar bore into petioles and mid ribs of large
leaves .When terminal shoots are attacked , the
growing points are killed .As a result the affected
leaves dry and drop down . After fruit formation
larva make their entry under the calyx when they
are young and close the entry point with excreta
and feed within it. sSevere damage is mainly
caused to the developing fruits by the caterpillar
as they tunnel inside the fruits.
Integrated Management of Brinjal shoot and
fruit borer -
• Grow less susceptible varieties such as Pusa
purple round, Brinjal long green, Pusa purple
cluster, Brinjal round white , Arka Kasumkar
etc.
• Continuous cropping or ratooning may be
avoided. Adjust the time of planting by
transplanting up to 4th week of June. Dip the
roots of the seedlings for 3 hours in
imidacloprid solution prepared at 1ml/lit before
transplanting.
• Avoid eggplant monocultures and follow crop
rotations. As EFSB is practically a
monophagous insect on eggplant, discontinuing
eggplant cultivation in a community for few
seasons will significantly reduce the
population.
• Do not raise eggplant seedlings near an
existing or previous eggplant crop or heaps of
dried eggplant stalks. If seedlings must be
grown in those areas, cover the seedling beds
with 30-mesh nylon net to prevent the entry
of EFSB moths, which would lay eggs on the
growing seedlings.
• Remove and destroy infested shoots and fruit
along with larvae promptly at regular intervals
until final harvest to manage EFSB. In heavy
infestation the whole plant should be uprooted
and destroyed . This will be highly effective
when practiced throughout a community.
• Pheromone trap@1 for 400 sq.m. + weekly
release of 50,000 to 60,000 Trichogramma
chilonis + two sprays of BT @1ml/L at 10
days interval at peak flowering . Place the traps
either at canopy level or at slightly above the
canopy level for effective attraction. This will
be highly effective when practiced in a
community.
• Use neem-based bio pesticides, which will not
interfere with the activities of predators and
parasitoids in eggplant production systems.
Apply neem cake at 250kg/ha at 30 days after
transplanting.
• The biological method of control of this pest is
introduction of some hyperparasites like
Pristomerus testaceus ( Mori.), Cremastus
flavororbitalis (Cam.), Bracon sp,
Pseudoperichaeta sp .etc. These
hyperparasites parasitize and feed upon the
larvae of this pest .

The flag utters
Utters on the blue mountain
With a venerable rhyme :
Come, come without doubt,
Come forward with all your urge
Looking at me.
Take assurance un-ending
Take this faith from wind that
Roams around me,
I shall draw-down your worries
For which
You are wheeled and twirled
Days and nights.
Why a look so saddy ?
Why for
Smiles not touching your lips ?
Learn to smile
The world shall be friendly,
The sky shall smile with you.
You have come
Where spring rounds
All the days,
Where twenty-two steps
Welcome all,
Where He waits for you
To shower blessings.
Come forward
With heart full of confidence.
