The consecutive survey of two states of India i.e. Bihar and Jharkhand are based on paddy and pulses cultivars of the areas during 2009 and 2011. Bihar’s economy is agrarian while in Jharkhand, agriculture is the mainstay of tribal population. During the survey it was observed that the paddy and pulses grown in the area were highly infested with grasshoppers. Samples collected were sorted out to yield 34 grasshopper species belonging to 25 genera, 2 families, 10 subfamilies and 19 tribes. Maximum number of grasshoppers collected belongs to subfamily Oedipodinae (9 species) followed by Oxyinae (4 species), Acridinae (4 species), Gomphocerinae (3 species), Catantopinae (3 species), Cyrtacanthacridinae (3 species), Pyrgomorphinae (3 species), Tropidopolinae (2 species), Hemiacridinae (2 species) with least number in case of Spathosterninae (1 species).
