Abstract

Temperature-time and temperature-velocity equations are given for egg, larval and pupal stages of Atherigona soccata Rond., based on stduies in Kanya. Preimaginal development (from egg deposition to adult emergence) on sorghum CSH-1 seedlings lasted 19.5, 26.3, 33.8 and 76.8 days at 30, 25, 20 and 15°C, respectively. A. soccata showed optimal development and survival at 30°C. The lower threshold temperatures were 13.8, 10.2 and 11.8°C for the egg, larva and pupa, respectively. The condition of the food-plant affected larval development and survival; pupal weight was higher and larval mortality lower in insects reared on fertilised and normally watered seedlings than on unfertilised and water-stressed seedlings
