  8. 8. DESCRIPTION  Nymph: First nymphal instars are elliptic, smooth and white, yellowish or translucent and mobile. They have low mobile legs and they are established near the egg-lay. After establishment they change into 2nd instar. Second and third nymphal instars are immobile, their size increase during development and the colour changes from semitransparent to creamy yellow.  Pupa: last instar is called as Pupa, yellow has distinct eyespots
  9. 9. DAMAGE:  Sucking cell sap  Injection of toxic saliva  Sooty mold  It is alone responsible for the transmission of about 50 diseases on 70 plants, important one is Cotton leaf curl virus

Three instars  Pupa: Male goes into pupal stage, which is white in color and covered by silken threads as cocoons
  19. 19.  Active Period :Active throughout the year  No. of generations :12 -15 generations
  20. 20. DAMAGE:  Adults and nymphs weaken the plants by sucking sap from leaves, twigs, stems, roots and fruiting bodies.  Bolls are deformed, fewer and smaller in size in affected plants.  Honey dew secreted by the pest encourages development of black sooty mould which adversely affecting photosynthetic activity.
  21. 21.

  22. 22. DESCRIPTION:  Adult: Forewings of Earis insulana are grass green  while the forewings of Earis vitella are straw yellow with a narrow light longitudinal green strip in the middle.
  23. 23. DESCRIPTION:  Eggs: Blue colored sculptured eggs laid singly or in groups on shoot tips and flowers
  24. 24. DESCRIPTION:  Earis insulana larvae are dull greenish white with a number of black marks on the body and orange spots on the prothoracic segment  while Earis vitella larvae are brownish with a median longitudinal streak and ventrum is pale yellow and green. Have six instars.
  25. 25. DESCRIPTION:  Pupa: Pupates in silken cocoon on plant or side soil
  26. 26. Adult: 18 – 34 days Eggs 3-4 days larva: 7-18 days Pupa 7-25 days
  27. 27.  Active Period : July – September  Inactive period : November – February  No. of generations : 6-8 generations
  28. 28. DAMAGE  Initially, the caterpillars will tunnel into buds, by destroying vessels and growing points, they cause adjacent blooms, young leaves and eventually whole shoots to turn blackish-brown and die off.  When fruiting starts, the larvae will turn towards the bolls, which then become brown and fall off as a result.  The entrance holes in bolls are neatly rounded
  29. 29. CONTROL  Non Chemical Control: ◦ After harvest, cotton plants (which can sprout from the stump) should be uprooted and destroyed ◦ Egg parasitoid:  Trichogramma chilonis  Chemical Control: ◦ lamdacyhalothrin (Karate 2.5 EC) 330 ml / acre ◦ indoxacarb (Steward 150 SC) 175 ml /acre
  30. 30. DESCRIPTION  Adult: Dark brown , forewings have blackish spots while margin of hind wings are deeply fringed  Eggs: Eggs are white when first laid but then turn orange  Larvae: Larvae are white with a brown head when they hatch. They have four stages of growth (instars) and begin to turn pink in the fourth instar.  Pupa: Yellowish brown and about the size of rice grain.
  31. 31. Adult: 2-29 days Eggs 3-7 days larva: 8-16 days Pupa 6-17 days
