Selenothrips rubrocinctus (Giard 1901) - (cacao thrips)

This thrips is widely distributed in tropical and subtropical regions, attacking the leaves of cacao, cashew, mango, avocado, ornamentals and other crops. On cacao, the feeding activities result in chlorotic spots and premature leaf drop. Pods may also be damaged and brown patches develop on the surface. This discoloration makes it difficult for worker to judge the ripeness of the pods. In other crops the damaged leaves might become deformed, silvery or necrocrotic before they drop.

The adult thrips is dark and reddish. The larvae and pupae are yellowish with a broad bright red band across the abdomen (see image below).
