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
 Pupa: Brown in colour, occurs in
soil, leaf, pod and crop debris
 Adult: Light pale brownish yellow
stout moth. Forewings are olive
green to pale brown with a dark
brown circular spot in the centre.
Hind wings are pale smoky white
with a broad blackish outer margin
1.Capitulum borer (Head borer): Helicoverpa
armigera

6. Pupa Adult
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
