Abstract

The present investigation was conducted for taxonomic documentation of insect pest fauna of rice. Information on insect pest fauna of rice ecosystem collected in Jabalpur region during the period between the last weeks of June to last week of December 2015.

Orders of minor significance are represented by Odonata and Neuroptera having 2 species each while Isoptera, Diptera, Dermaptera and Dictyoptera were represented by one species only. These species were grouped on the basis of their economic importance in three major categories viz. Harmful insects- as crop pests 32 species, beneficial insects- as bio-control agents (predators and parasites) 28 species and beneficial insects- as commercially important 2 species.
