The Biology and Control of Oemida Gahani Distant, (Cerambycidae), in Kenya (O.D.C. 453)

Abstract

The Cerambycid borer, Oemida gahani Dist. attacks living Cupressus and Juniperus procera plantation trees in Kenya Highland forests, where it is indigenous in the natural forest. It is considered to be the most important forest pest at present in Kenya. An account of recent research on the biology of the pest is given, with particular reference to the relative susceptibility of indigenous host species. The effect of this on the incidence of the pest in different areas and especially in cypress plantations, is discussed. Information on the degree of attack of plantations and resultant damage and degrade to the timber, is followed by an account of control measures and recommendations for the treatment of timber for external use and for export.
