摘要：

Callosobruchus maculatus was reared on Vigna unguiculata, Phaseolus radiatus and Dolichos lab lab from hatching to death at 20, 25, 30 and 35°C. Food consumption, growth and egg production were estimated in terms of energy. At the tested temperatures, host seed species significantly influenced feeding and energy allocated to egg production. Irrespective of the seed species, food consumption decreased with increasing temperature. Energy density of an egg did not vary with seed species but significantly decreased with increasing temperature. Fecundity (egg/females) of Callosobruchus maculatus ranged from 73 on D. lab lab at 35°C to 118 on Vigna unguiculata at 30°C. Energy allocated to egg production at 20°C was more than at other temperatures. A statistically significant inverse relationship exists between overall feeding rate of Callosobruchus maculatus and energy allocated to egg production.
