Abstract :

 Objective: To study the larvicidal activity is studied and compared for different fractions of extracts of C. inerme plant leaves in solvents like petroleum ether chloroform and methanol. The targeted larvae’s were 3rd and 4th instars larvae of Aedes ,Culex and Anopheles. Methods: In present investigation, extracts of C.inerme were prepared by refluxing plant leaves using petroleum ether, chloroform and methanol sequentially and were tested for larvicidal activity. Results and conclusion: It has been observed that petroleum ether extract is more effective than chloroform and methanol for mosquito larvae’s of Culex and Aedes. In conclusion the petroleum ether extract can be used as herbal insecticide to inhibit mosquito eeding sources.
