Abstract
Fluctuations in numbers of adult sorghum shootfly, Atherigona soccata Rondani were related mainly to rainfall pattern. Immediately after peaks in rainfall, there was peak emergence of adults, as determined by the emergence cages, and 4–6 weeks later there were peaks in total adult numbers, as determined by sweeping. Sorghum sown earlier in the growing season was damaged far less than that sown later in the season when shootfly density had increased. There was apparently a natural disproportion in the number of females. The sex ratio varied between 1:1.4 and 1:1.9, males to females
