Species Guides
1- Selenothrips rubrocinctus(redbanded thrips)
Selenothrips is a of in the Thripidae, established by Heinrich Hugo Karny in 1911. The genus contains at least two described : S. rubrocinctus (Giard, 1901), commonly known as the red-banded thrips or cacao thrips, and S. glabratus Priesner, 1927. S. rubrocinctus is a pest with broad tropical and subtropical distribution, known to attack cacao, cashew, mango, avocado, and other crops. Research on this species has focused on its feeding in relation to plant water-stress and availability.
