The intra-seasonal progression of larval infestations of Busseola fusca (Fuller) and Chilo partellus (Swinhoe) in grain sorghum was investigated by means of two-weekly sampling from two to sixteen weeks after crop emergence. Variation in planting date and fluctuations in both inter- and intra-seasonal moth numbers was provided for by using nine different planting dates in each of three seasons, in this way obtaining a general pattern of infestation for each borer species.
