The Guar or cluster beans (Cyamopsis tetragonoloba) is an annual legume and the source of guar gum. This legume is a very valuable plant within a crop rotation cycle, as it lives in symbiosis with nitrogen-fixing bacteria. In fact, agriculturists in semi-arid regions of Rajasthan follow crop rotation and use Guar as a source to replenish the soil with essential fertilizers and nitrogen fixation before the next crop. About 80% of world production occurs in India and 70 per cent in Rajasthan. The present study was undertaken to survey the insect fauna associated with this crop in an agro-ecosystem situated in the Indian desert in Jhunjhunu district of western Rajasthan. The insect visitors were surveyed and collected every week from July to October. Cage net was used for insect collection. In all, 51 insect species belonging to 7 orders and 27 families were collected from the crop of which 6 were dominant, 25 were frequent and 20 were rare forms. Maximum density as well as diversity of entomo-fauna was noted in the month of July while October was the month which had minimum density and diversity of insects.
