Abstract
Archips occidentalis (Wals.) and Tortrix dinota Meyr. have recently become more common on arabica coffee in the East Rift areas of Kenya. The larvae attack the leaves,shoot-tips and fruit. The life-history and biology of both species are described. The complete life cycle takes about 8 weeks. Characters distinguishing the two species are given. Several hymenopterous parasites were recorded of which Apanteles ugandaensis Gahan was the most common. A larval disease was also noted. Trichlorphon, at 1.6 lb. per active per acre, was found to be effective against the larvae.
