Sorghum bicolor, commonly called Sorghum and also known as jowar, or milo, is a grass species cultivated for its grain, which is used for food for humans, animal feed, and ethanol production. It is cultivated widely in tropical and subtropical regions. Sorghum is the world's fifth-most important cereal crop after rice, wheat, maize, and barley. In India, where it is commonly called jwaarie, jowar, jola, or jondhalaa, Sorghum is one of the staple sources of nutrition in Rajasthan and the Deccan plateau region in states of Maharashtra, Karnataka and Telangana.

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 study concentrated on documenting the diversity and density of insect visitors to Sorghum crop cultivated in the crop field employing an indigenously designed cage. The insect visitors were surveyed and collected every week from April to June. In all, 39 insect species belonging to 6 orders and 21 families were collected from the crop of which none were dominant, 15 were frequent and 24 were rare forms. Maximum diversity and density of entomo-fauna was found in the month of June, while the minimum density and diversity was noted in the month of April.
