Abstract
An account is given of the African armyworm, Spodoptera exempta (Walk.), as a noctuid pest of agriculture, and of the recent research into its biology and control in East Africa. Salient features in its biology and zoogeography are discussed, from the standpoint of the way in which they determine control methods and strategy. Special attention is given to the forecasting of outbreaks. Comparative reference is made to forecasting systems and techniques as practised in other countries and with different insects.
