Toxicity of Biosal essential oil against Callosobruchus analis by three methods Direct Application Method (DAM), Glass Film Method (GFM) and Filter paper Impregnation Method (FIM) after 24 hours of treatment. The LC50 value calculated as 1.338504 µl/cm2 by DAM, 12.174 µl/cm2 by GFM and 6.945603 µl/cm2 by FIM. Fecundity was observed after 15 days of treatment of Biosal againstCallosobruchus analis number of emergence by three different methods was noted, In direct application method it was 72% and 67.74%, In glass film method it was 83.33% and 76.69%, In filter paper impregnation method 88.8% and 79.16% respectively in treated and control insect, while after 30 days of treatment of Biosal against Callosobruchus analis by direct application method average number of emergence observed in control and treated insects was 85.29% and 69.56% respectively, In glass film method emergence was observed in control and treated insects as 94.94% and 88.85% respectively, in filter paper impregnation method average number of emergence was observed in control and treated was 97.15% and 91.72% respectively.
