Characteristics of Eggplant Fruit and Shoot Borer
Scientific name: Leucinodes orbanalis
The adult is a butterfly, with a body length of 13-14mm, and white wings, with brown and pink spots on the wings.
Butterflies lay eggs in clusters on the undersides of leaves, flower buds, and young fruit. One female can lay up to several dozen eggs. Eggs are milky white, flattened, and arranged in the shape of roof tiles.
Young caterpillars are ivory-white, then turn pale pink, pushing their strength from 15-18mm. Also, the pupa is brown. On average, their cycle life of them lasts 30-40 days, and the growth time of larvae is 15-20 days.
Butterflies often hide under grass and leaves during the day and are active at night. Not only the fruit is affected by the pests, but also the young shoots are attacked. They bore into the top and cause the top to wilt.
For the fruit, the caterpillar bores inward and leaves a small hole. If the fruit is damaged, the intestines will be empty because the worm has eaten all the flesh. The inside of the fruit is filled with worm droppings, causing partial or complete damage to the fruit.
Many times, the young caterpillars also drill into the fruit stalks, making the fruit unable to grow or wilt. When it rains, the damaged fruit is easy to rot because the hole contaminates with microorganisms.
The caterpillar pupates in the damaged fruit or stem or hides in the fallen leaves. In the rainy season, the damage is most severe, especially in periods of heavy rain with high air humidity.
