The study of biodiversity associated with agro ecosystem is of significance for agro ecologist and conservation biologist, since the maintenance of biological diversity is essential for productive and ecologically sustainable agriculture. Field experiment was conducted to inventorize the insect fauna in pigeon pea ecosystem from February 2015 to July 2015. A total of 77 different species of insects belonging to 45 families under 10 orders were collected. Of the 77 species recorded, 53 species were harmful and 24 were beneficial. The Simpson’s index of Diversity was the highest for beneficial insects (0.94) and for harmful insects it was (0.93). Similar trend was observed in Shannon-Wiener index also for beneficial and harmful insects with values of 3.12 and 3.00, respectively. The values of Margalef index for the beneficial and harmful insects revealed that maximum richness (6.35) was accounted for harmful insects followed by beneficial insects (5.32). The species evenness was maximum for beneficial insects (0.55), whereas for the harmful insects it was (0.45).
