ABSTRACT

Cotton bollworm, Helicoverpa armigera (Hubner)is very important polyphagous insect pest with wide host range known for its economic losses worldwide. Its ability to develop resistance to insecticides faster to identify alternates like biocontrol agents, plant extracts etc. In the present study the extract of Citrullus colocynthis in different solvents were evaluated on second instar larvae of H. armigera under laboratory studies for toxicity, sublethal and antifeedant effect. The result showed that ethanol based extract was the most effective to control the H. armigera followed by the ethyl acetate. The sublethal concentration of ethanol based extract of C. colocynthis increased larval and pupal duration as compared with control. The percent pupation, adult emergence and pupal weight decreased in treated populations as compared with control populations. The results of this study can be used in integrated pest management program for the management of H. armigera.
