Abstract: The desert locust, Schistocerca gregaria, is the most dangerous herbivore species of locust. The present investigation aimed to throw light the effect of methylene chloride extracts of Azadirachta indica, and Euphorbia granulate on the 2nd instar nymph of Schistocerca gregaria under laboratory condition. The results showed that the methylene chloride extract of A. indica, are the most potent extracts against Schistocerca gregaria. The present study was also extended to conduct the insecticidal effect of the most potent extracts Azadirachta indica, and Euphorbia granulate methylene chloride extract on Schistocerca gregaria. The present result showed that Azadirachta indica, and Euphorbia granulate extract caused not only mortality in larval stages, but also caused effect on pupal and adult duration, adult fecundity and egg fertility. Also extracts of Azadirachta indica, and Euphorbia granulate extract treatments have resulted in emergence of deformed pupae and adults.Also, the data showed that Marked biochemical changes however, being recognized in pest as marked decrease in total lipids, total protein and glucose contents. The activity of both ALAT and ASAT are also being highly affected.
