Abstract
In this study larvae of Helicoverpa armigera (Hübner) were reared on artificial diet in controlled room. Extract of Artemisia annua L. a medicinal plant was incorporated into diet in various concentrations (i.e. 12, 14, 16, 18, 20 and 22 g/g of artificial diet). The LC10, LC30 and LC50 values after 48 h treatment were estimated to be 12.4, 16.12 and 19.32 g/g of diet, respectively. The major constituents of the extract of A. annua were determined by GC-Mass. The results of present study confirm the earlier findings on this plant species as a potential medicinal plant in the possible control of several insect pests of crops.
