Abstract

Sporadic outbreaks of many pine defoliators, including Orgyia hopkinsi Coll., have occurred in many pine plantations in Kenya in the last 20 years. A recent outbreak of O. hopkinsi is reported from young plantations in Turbo. Distribution, hosts, and epidemiology of the insect are discussed. The stages, life history, and habits are described. Eggs are laid on the bark close to pupation sites or on the pupal cases. The larvae feed on the foliage and pupate following the fifth instar. The life cycle lasts 76 to 94 days. Two species of parasites, namely Pimpla mahalensis Grib. and Pimpla sp. (Hymenoptera: Ichneumonidae), have been observed. Other controlling factors are also discussed.
