3. Symptoms of damage:
Leaf Feeding
The larva feeds on the
developing seeds and
bore the head
Fungal developed and
head starts rotting
The larva consumes leaf
in early stage of growth
and move towards the
capitulum and tunnel the
head
1.Capitulum borer (Head borer): Helicoverpa
armigera
4. Larva feeding in seed Caterpillar bore into head
1.Capitulum borer (Head borer): Helicoverpa
armigera
5. Identification of the pest:
Larva
Egg: Spherical in shape and creamy
white in colour, laid singly
Larva: Shows colour variation from
greenish to brown. It has dark brown
grey lines on the body with lateral
white lines and also has dark and
pale bands

stout moth. Forewings are olive
green to pale brown with a dark

1.Capitulum borer (Head borer): Helicoverpa
armigera
7. Symptoms of damage:
Larval Feeding
Young larvae feed
gregariously mostly on
the under surface of the
leaves
Caterpillars feed on
leaves and in severe
infestation the whole
crop is defoliated
Drying up of infected
leaves is the main
symptom
2.Hairy caterpillar: Spilosoma obliqua
8. Identification of the pest:
Egg: Laid in cluster on
the underside of leaves
Larva: Covered with
long yellowish to black
hairs
Adult: Medium sized
brown moth with a red
abdomen. Wings pinkish
with numerous black
spots
2.Hairy caterpillar: Spilosoma obliqua
9. Symptoms of damage:
Larva feeding
The larvae feed on the
tender leaves, shoots,
bracts and petals
Later, the larvae spread
in the field causing
defoliation
The larvae also feeds
on the developing
seeds in capitulum
3.Tobacco caterpillar : Spodoptera litura
10. Identification of the pest:
Adult
Egg: Egg masses appear
golden brown
Larva: Pale greenish with
dark markings, gregarious
in the early stages
Adult: Forewings are
brown colour with wavy
white marking. Hind wings
are white in colour with a
brown patch along the
margin
2.Hairy caterpillar: Spilosoma obliqua
11. Symptoms of damage:
The adult and nymphs
suck the plant sap
The infected leaves show
pale yellow colouration
In case of heavy
infestation the leaves
turn inwards
The leaf edges may turn
light pinkish brown
4.Leaf hopper (jassids): Amrasca biguttula
biguttula
12. Identification of the pest:
Nymphs: Pale greenish
almost translucent and
walk diagonally
Adults: Greenish
yellow, wedge shaped
with a pair of black spots
on vertex and a black
spot on each of the
forewings
4.Leaf hopper (jassids): Amrasca biguttula
biguttula
13. Symptoms of damage:
The birds damage
starts from the milky
stage and continues till
harvest
These consumes on an
average of 152
seeds/day
5.Parakeet: Psittacula krameri
14. Identification of the pest:
It is slim, green
parakeet with the
typical short, heavy,
deeply hooked, red bill.
Hollow space in a tree
trunk is the nest of the
bid
5.Parakeet: Psittacula krameri
