Worldwide distribution. On beans, capsicum, cotton, maize, okra, sorghum, tomato, and to a lesser extent legumes, tobacco, and many weeds. An important pest.
Eggs laid on tomatoes or weeds nearby. At first, the larvae feed on leaves; later, bore into flowers and fruit. Fungi and bacteria enter and cause rots.
In maize (corn), damage to tip of cob allows weevils to invade.
Natural enemies: present but often too slow to prevent damage when large numbers of moths invade an area.
Cultural control: remove weeds, and collect remains of crops and destroy. Scout for young caterpillars. Plant sunflowers at random as a trap crop, attracting moths to lay eggs.
Chemical control: Bt (Bacillus thuringiensis) or NVP (against early stages). Synthetic pyrethroids, alternate with other insecticides in different groups to avoid resistance occuring, but they will kill natural enemies.
