ABSTRACT
The insecticidal activity, expressed by LD50 values, of acetone, ethanol, petroleum ether and water extracts of Calotropis procera leaves against the flesh fly, Sarcophaga hemorrhoidalis Fallen was evaluated in the laboratory. Based on LD50 values, ethanol extract was nearly 1.7, 1.3 and 1.3 times more toxic to larvae than water, petroleum ether and acetone extracts, respectively. It was 1.9, 1.4 and 1.2 times more toxic to pupae than water, acetone and petroleum ether extracts, respectively. It was 2, 1.5 and 1.4 times more toxic to male flies and 2.2, 1.6 and 1.4 times more toxic to female flies than water, petroleum ether and acetone extracts, respectively. Thus, ethanol extract of C. Procera was the most toxic, of all solvents used, to different stages of S. hemorrhoidalis. The findings suggested also that C. procera extracts may produce larvicidal, pupicidal and adulticidal effects [as general toxicants] against the flesh fly, S. hemorrhoidalis
