Parasitic wasps, Dinarmus acutus (Thompson) and Dinarmus basalis (Rondani) (Hymenoptera: Pteromalidae) parasitizing pulse beetle Callosobruchus maculatus (Fabricius)

摘要

A survey of pulse beetle, Callosobruchus maculatus (Fabricius) infestation in greengram (Vigna aureus Roxb.) was conducted in different villages of districts Alwar and Jaipur (Rajasthan). The parasitic wasps, Dinarmus acutus (Thompson) and D. basalis(Rondani) have been observed as potential parasitoids, with parasitism ranging from 13 to 29 per cent. Only the last instar larvae and pupae of C. maculatus were parasitized.
