Larval parasitoid, Bracon hebator (SAY) is being utilized in various bio-control research, developmental and extension units for management of lepidopteran peast in their larval stages. Larval parasitoid B. hebator ranks first in the management of lepidopteran insects.  Production of B hebator nutritional requirements have to be taken into account because nutritional deficiencies have been linked with such vague symptoms like poor growth rate, lowered fecundity or reduced body weight. As it is one of the most effective parval parasitoid for different lepidopeteran pests various dietary formulations were developed in the present study with differet combinations and the effects of these formulations on the growth, development, reproduction of B hebator were reviewed.
