Abstract
The average duration of development from egg to adult of the sorghum shoot flies (Atherigona spp.) was 29.5 days. The highest catches of flies in baited traps were taken during or just after wet periods. The relationships between the shoot flies and nineteen sorghum cultivars were examined. Within the ranges observed, the size of the adult fly population and the number of eggs were less important for the resulting damage than were the conditions for plant growth, i. e. favourable conditions reduced the infestations. Infestations varied widely between cultivars in early plantings, with diminishing variation as the general attacks increased with later plantings. Sorghum in the four to six leaf stage was highly preferred for oviposition. Tolerance, antibiosis, non-preference for oviposition, and good agronomic properties were scattered on different cultivars, thus indicating that plant breeding of sorghum for East African conditions should be encouraged
