Damage & Symptoms

The caterpillar feeds on leaves and stems, but the main damage is to the crop’s reproduction organs such as capsules, pods, buds, berries, and inflorescences. This causes the rotting of the fruit and leads to fruit dropping. The large holes left o plant tissues make them susceptible to fungi and bacteria
