The study was carried out during 2013-2016, at the Biological Control Studies and Researches Center (Faculty of Agriculture, Damascus university/ Syria). It aimed to etermine the biological characteristics, sex ratio and natural factors of death for parasitoid Cotesia glomerata when it's reaed on three of laboratory hosts: Aporia crataegi, Galleria mellonella, Pieris brassicae: the highest percentage of parasitism was in larvae P.brassicae (88%) from the total number of larvae were used in the experiment. The P.brassicae larvae were the best host to put in the highest number the parasitoid eggs, and the number of parasitoids larvae which emerged from each larva of P.brassicae was 24.7 ± 2.54 larva. But accordance to Brodeur et al, (1998) equation the parasitism percentage of A.crataegi was close to P.brassicae, but the natural death factors of parasitoides were different. The failure of the parasitoid larvae to emerge from the host larvae was the highest for the larvae of G. mellonella (21.8%), and the failure to form cocoon and pupa death inside the cocoon were closer between the three insect species.In contrast to laboratory experiment, the sex ratio in the field was tend more towards females than males, on the three species. The period of eggs to hatch and larval stage depend on host diapauses, which was the longest for A.crataegi larvae.
