Nature of Damage

  • The early instar tiny larva nibbles mostly near the midrib of tender leaves (Fig. 1), while later second instar onwards, larvae (Fig. 2) fold the leaf from midrib and web it from margin giving appearance like ‘Pea pod’ shape (Fig. 7 & 8) or bind 3-4 leaves together and feed from inside the bounded leaves (Fig. 5  & 6). 
  • The larvae remain inside the leaf and feeds within on green matter.
  • The damage of this pest can be visualized by the presence of dried terminal shoots with dried leaves (Fig. 3 & 4).
  • Its damage also reported on the leaves of Khirnee rootstocks in nursery.
