Integrated Pest Management of Brinjal Shoot & Fruit Borer
• Shoot and fruit borer is the most destructive brinjal pest. Brinjal shoot and fruit borer larva feeds into the petioles and tender shoots. It results in withering leaves and shedding flower buds.
• Caterpillars cause severe damage to the growing fruits as they tunnel inside the fruits. A single caterpillar can destroy as many as 4-6 fruits. Damaged fruits show holes in the circular exit.
• The entry holes on the brinjal fruit can also be seen plugged with excreta, making the fruit inappropriate for consumption.
