Abstract

Haemolymph proteins of Euprepocnemis plorans nymph and adult females were estimated after they feeding on different foods,and trypsin activity in midgut of nymphs. Electrophoresis of heamolymph from grasshoppers fed on lupin (Lupinus trmis) or horsebean (Vicia faba) showed much less stainable protein in comparison to those fed on clover (Trifolium alexandrinum). Trypsin activity in midgutt wall or in midgut were lower in nymphs fed on lupin or horsebean than those from nymphs  fed on clover
