Abstract: A preliminary study was conducted on the abundance and diversity of insects species in agriculture fields of Hadagil Harutti village, Gulbarga, Karnataka. The present study was aimed to determine the species richness, dominance and evenness of insect fauna from agriculture fields. The study was carried out during the month from June 2013 to September 2013. A total of 11, 318 insects from 6 orders, 26 families and 54 species were recorded. This study shows that Hymenoptera (78.86 %) was the most dominant order according to total number of individuals, followed by Coleoptera (15.45 %), Lepidoptera (3.22 %), Hemiptera (1.47 %), Orthoptera (0.95 %) and Diptera (0.05 %). The Simpsons Reciprocal Index diversity is highest in order Coleoptera (8.048) and lowest in order Diptera (1.000). The species richness, evenness and diversity of insects was calculated by Margalefs Index, Pielous Index and Shannon-Wiener Index respectively.
