Present research was conducted to study the effect of the host species on the developmental duration of the immature stages of the larval parasitoid, Bracon hebetor and on the biological aspects of the adults of the parasitoid when reared on three different hosts: the great wax moth Galleria mollonella, the Mediterranean flour moth Ephestia kuehniella and the fig moth Ephestia cautella. The results showed that the species of host had a significant effect on some development of the immature stages of the parasite, B. hebetor, as the longest period of the pupa duration on the G. mellonella host was 7.37 days, while the shortest period of the pupa duration on the E. kuehniella host was 4.87 days. The results indicated that there was a significant difference in the period of development from egg to adult of the parasite when reared on host G. mellonella and host E. kuehniella, which amounted to 12.97 and 10.07 days, respectively, on the one hand, and between host E. cautella and host E. kuehniella on the other hand were 11.93 and 10.07 days, respectively. The results also showed that the highest value of the percentage of eggs hatching was 86.60% on the host G. mellonella, while it was 53.7 and 67.80% on the hosts E. kuehniella and E. cautella, respectively.
