Hymenopteran parasitoids have an important role in agroecosystem because of their ability in suppressing pest population. Their presence in the field is seen as the key to agricultural ecosystem. Their presence can be influenced by the plant protection measures. The objective of this research was to study the status and diversity of hymenopteran parasitoid in unprotected and protected condition of MARS, Raichur and ARS, Gulbarga. Collections were made in unprotected and protected conditions of MARS, Raichur and ARS, Gulbarga by three trapping techniques (malaise trap, sweep net, and yellow pan traps). There was a significant difference of hymenopteran parasitiods between the unprotected and protected conditions of both locations (MARS, Raichur and ARS, Gulbarga). The hymenopteran parasitoids were significantly more in unprotected condition having higher Simpson and Shannon weiner diversity indices with a more evenness and less number in protected conditions of MARS, Raichur and ARS, Gulbarga. Pesticide application affected the species richness, diversity and evenness of hymenopteran parasitoids in unprotected and protected conditions. Seven super families and seventeen families were identified by using the keys, which were collected in both unprotected and protected ecosystem of MARS, Raichur and ARS, Gulbarga.
