Extract

Three egg parasites, Sozites kerichoensis Kerrich (Ichneumonidae), Oligositoides semicinctium De Santis (Trichogrammatidae), and Platystasius benjamini Nixon (Scelionidae) were reared from egg-masses of two closely related Entypotrachelus species indigenous in the tropical rain forest of Kenya. E. meyeri Kolbe occurs west of the Rift Valley, and E. micans Hust. occurs in the foot-hills south and west of Mt. Kenya, east of the Rift Valley. When the forests are cleared, both species transfer from forest trees, weeds and shrubs to newly planted tea and Cinchona spp. where the larvae feed on the roots and the adults feed and oviposit on the leaves.
