Shoot and fruit borer

The damage to the fruits starts soon after transplanting and continues till harvesting of the fruits.
It can reduce yield by as much as 70%.
Multiple overlapping generations occur in warm climates.
The short pinkish larva of the pest initially bore into the terminal shoots resulting in withering and drying of the shoot.
In the later stage, it bores into the young fruits by making holes and feeds inside and lose their market value fruits plugged with excreta.

Management:

Install pheromone trap @ 5 /acre .
Continuous cropping of brinjal on the same piece of land should be avoided.
Fruits showing boring should be picked and destroyed.
Spray the crop with Cypermethrin 10% EC @ 300ml/acre or Lambda Cyhalothrin 5% EC @ 200-250 ml/acre at fortnight intervals starting from 35 days after transplanting to control the pest.
Best results are obtained when all the affected fruits are removed before spraying.
