oa Journal of the Entomological Society of Southern Africa - The assassin bug, Platymerus rhadamanthus Gerst (Hemiptera: Reduviidae), a useful predator of the rhinoceros beetles Oryctes boas (F.) and Oryctes monoceros (Oliv.). (Coleoptera: Scarabaeidae).

The rhinoceros beetles Oryctes boas (F.) and O. monoceros (Oliv.) do serious damage to coconut palms in Zanzibar and East Africa. These beetles breed in decaying wood, particularly decaying palm trunks, and in manure and compost heaps. They lay their eggs in the decaying vegetable matter, often boring well inside to do so. The eggs, white and the size of mustard seeds, hatch in 7 to 9 days. The larvae take between one hundred and two hundred days to reach maturity according to temperature and availability of food; and the pupal stage lasts from 14 to 21 days.
