The recent development of geographic information systems (GIS) provides new avenues for analysing spatial patterns in insect populations. Field survey data, along with GIS and statistical models were used to predict the distribution of Chilo partellus (Swinhoe) (Lepidoptera: Crambidae) and Cotesia flavipes Cameron (Hymenoptera: Braconidae) in Ethiopia. The results obtained suggested that the distributions of Ch. partelhis and Co. flavipes were affected by rainfall and temperature. The predicted distributions of Ch. partellus and Co. flavipes were similar. Validation of predicted values is discussed.
