The peed of development, (Egg to adult emergence) of Trichogrammatoidea bactrae ranged from 7.273 to 6.532 days between temperatures 30 to 40 C. Immature mortality was maximum (71.88%) at 40 C and minimum (39.77 %) at 30 C. More females than males were found at all tested temperatures. Fecundity was 31 per female at 30 C and 19 per female at 40 C. Females lived longer than males at all tested temperatures. The net reproductive rate (Ro), intrinsic rate of increase (rm) and finite rate of increase ( ) (16.98, 0.30 and 1.43 respectively ) were maximum at 30 C. From these results, 30 C is the best temperature for rearing T. bactrae in the laboratory with 45% RH and 14/10 photoperiod. At 30 C parasitoid can produced about 33 generations in a year. Upper threshold temperature for T. bactrae looks around 45 C.
