Natural Enemies Associated with Arthropod Pests of Pigeonpea in Eastern Africa

Common arthropod pests and beneficial species were surveyed on pigeon peas in Kenya, Malawi, Tanzania and Uganda, during 1995-96. Three pest groups were found: pod-boring Lepidoptera (Helicoverpa armigera, Maruca vitrata and Etiella zinckenella), pod-sucking bugs (mainly Clavigralla tomentosicollis) and pod fly (Melanagromyza chalcosoma). Natural enemies included Coleoptera, Hymenoptera, Diptera and Hemiptera and were found more frequently in Kenya than in the other countries

Use and misuse of pesticides by farmers in Kenya in pigeon pea crops is discussed. Inadequate knowledge of production technology, pest life-cycles and timing of pesticide applications is highlighted

Pigeonpea Seed Damage from Insect Pests on Farmers' Fields in Kenya, Malawi, Tanzania, and Uganda

In on-farm field studies in in 1995 in Kenya, Malawi, Tanzania and Uganda, Helicoverpa armigera, Maruca testulalis [M. vitrata], Clavigralla sp. and Melanagromyza chalcosoma were identified as the major pests of pigeon peas. M. vitrata was not found in Malawi
