        abstract = {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.}
