Damage

2. Later on it folds and webs the leaves and feeds within.
3. It also feeds on flowers and bores into developing fruits.
Eggs of Diaphania indica are laid singly or in clusters on the lower surface of leaves. On hatching, the larvae feed on the lower surface of leaves which are lacerated and bound together by threads of silk. In severe outbreaks, most of the foliage is destroyed and larvae burrow into the stems, feed on flowers, new tender shoots and young and developing as well as mature fruits in case of little and bitter gourd. The fruits are sometimes attacked particularly at the proximal end. Damage to the fruit is 60% in bitter gourd to 90% in little gourd.
ETL for Diaphania indica is 8-10 No’s of moths per trap per day.
Use 8 No’s Pheromone Traps per acre from 15 days crop stage to control pest at early stage. Trap canopy should be placed one feet above crop canopy to achieve optimum catch.
