Surveys were conducted in paddy ecosystem in different districts of Southern Rajasthan during 2008-09 and 2009-10 to study the density and diversity of acridid species. Results revealed that species diversity was maximum in Udaipur during both the years of study with the Shanon Weiner Diversity Index being 2.141 and 2.106, respectively. The acridid mean and relative density values varied considerably in the paddy ecosystem and population of Oxya spp. was most abundant with a range from 24.48 to 29.92 per cent during both the years. However, relative density of Heiroglyphus banian Fabricius was also relatively higher over rest of the acridid species with 16.93 to 19.60 per cent during 2008-09 and 2009-10, respectively.
