Study of mating effect, hosts range and competition with the parasitoid Bracon hebetor on some behavioral and biological aspects of larval parasitoid Goniosus sp

Laboratory studies was conducted to investigate effect of mating behavior on egg laying, host selection and competition with Bracon hebetor. The results showed that no differences in laying between mated unmated females. number were 90.67 per female females respectively. However produce only males progeny.The parasitoid response the larvae different lepidopterous insects such as. Mediterranean flour moth, potato tuber warm, greater wax tomato leafminer, Angoumois Grain Moth lesser date moth. did not respond Corn stem borer cotton bollworm (tomato fruitworm) .The study parasite Goniozus sp B. hebetor indicates first more competitive parasitism where percentage 72.22% total larvae, while, 27.77% for B.hebetor.
