The black blister beetle Meloe proscarabaeus is firstly recorded in Egypt during 1970s. The present work was carried out aiming to investigate the effects of feeding on different host plants, viz. Vicia faba, Trifolium alexandrinum, and Lactuca sativa, on the general body metabolism of adult females. Concerning the carbohydrate content (CC) in haemolymph, feeding on V. faba resulted in unchanged content during the ovarian maturation period and oviposition period but decreased during the postoviposition period. By feeding on T. alexandrinum or L. sativa, CC gradually decreased through the successive time intervals. With regard to CC in the fat body, no change could be detected during the first two successive intervals while a slight increment was estimated during the post-oviposition period, after feeding on V. faba. Another fashion was determined by feeding on T. alexandrinum or L. sativa. The protein content (PC) gradually decreased in haemolymph by the adult age after feeding on V. faba. On the contrary, PC appeared in another course by feeding on L. sativa but no certain trend could be explored after feeding on T. alexandrinum. PC in the fat body turned down by age after feeding on V. faba or L. sativa, but another trend could be conceived by feeding on T. alexandrinum The lipid content (LC) in the haemolymph, after feeding on V. faba, was promoted during the oviposition period and then was prohibited during the last life interval. Feeding on T. alexdandrinum or L. sativa led to gradually increasing LC during the oviposition period and the next period. In the fat body, LC increased progressively by age after feeding on V. faba and a similar approach could be easily seen during the time intervals of adult females fed L. sativa but not fed T. alexandrinum
