Life Cycle of Chilli Fruit Borer Pest in Chilli Crop

The life cycle of the Chilli Fruit Borer pest has four stages. They are egg, larva, pupa, and adult. The Chilli Fruit Borer moth lays eggs singly or in small clusters on the Chilli plant’s developing flowers, fruits, and pods. The incubation period of the eggs is 2-5 days, depending on the temperature and humidity. The newly hatched caterpillars feed on the Chilli plant’s developing pods, flowers, and fruits. The larvae undergo five to six instars before entering the pupal stage.

The larval stage duration varies from 10-20 days, depending on the temperature and food availability. The fully grown larvae pupate in the soil or on the plant. The pupal stage is a resting stage where the insect undergoes metamorphosis and becomes an adult moth. The pupal stage lasts 7-14 days, depending on the temperature. The adult moth emerges from the pupa and is nocturnal. The female moth lays eggs on the Chilli plant, and the cycle continues.
