A four-year (1988 to 1991 inclusive) field and laboratory study was undertaken to determine and select the components that could be integrated to control the sorghum shoot fly, Atherigona soccata Rondani (Diptera: Muscidae), in Burkina Faso, West Africa. Nine approaches were investigated: (1) monitoring adult shoot flies; (2) sequential sampling based on egg and dead heart counting; (3) cultural practices (sowing dates and plant densities, intercropping sorghum-cowpea); (4) use of resistant cultivars; (5) use of natural insecticide from the neem tree Azadirachta indica A. Juss. (Meliaceae); (6) effects of intercropping sorghum-cowpea on the natural enemies of the shoot fly; (7) spider fauna in pure sorghum and intercropped sorghum-cowpea; (8) parasitism of the shoot fly by a larval parasitoid, Neotrichoporoides nyemitawus Rohwer; and (9) the biology of an egg parasitoid, Trichogrammatoidea simmondsi Nagaraja. These nine approaches were divided into four main components: (1) monitoring populations, (2) cultural practices, (3) natural and chemical pesticides, and (4) biological control that could be integrated to control the shoot fly. Among these components, monitoring populations (egg sampling), cultural practices, and use of natural pesticides could be utilised at the farmer level.
