  1. 1. Sunflower Crop Insects A Presentation To IPM Course/FFS Participants By Mr. Allah Dad Khan Provincial Coordinator IPM KPK For MINFAL Pakistan
  2. 2. 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
  3. 3. Larva feeding in seed Caterpillar bore into head 1.Capitulum borer (Head borer): Helicoverpa armigera
  4. 4. 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
  5. 5. Pupa Adult 1.Capitulum borer (Head borer): Helicoverpa armigera
  6. 6. 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
  7. 7. 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
  8. 8. 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
  9. 9. 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
  10. 10. 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
  11. 11. 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
  12. 12. 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
  13. 13. 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
