Abstract
Callosobruchus maculates F. is one of the most serious insects, that causing huge damages to several chick – peas seeds in many area in the world. This insect is an active source of researches because of its spread in great area especially in the grain stores. So this research is concentrated on the toxicant influence of the extracted alcohols on three kinds:- Eruca sativa, Raphanus sativus and Lactuca sativa. The seed and papers of were employed throughout with seven concentration: (1000, 2000, 4000, 7000, 9000 and 10000) part per millions and the treatment is accomplished in a complete cycle of the insect life time by monitoring the effect after 24 and 48 hours respectively. In addition to that it is compared with reference sample results these results exhibited the killing effect of each extracted plant employed in this study, the result indicates that the Eruca sativa is the highest percentage killing of the mentioned insect which was exactly 100% with concentration 1000 ppm and the lowest percentage of killing was by Lactuca sativa papers which exactly was 54.125% with concentration 10000 ppm after 48 hours of treatment. The results indicated also that all extracted plants influence on eggs number, eggs inculpation period eggs hatching, larval stage period, pupal stage period and on adults emergence number under different temperature and humidity.
