dc.description.abstract Instead of developing easily degradable, and low-priced insecticides, we are going after highly sophisticated chemicals. Here, an attempt is being made to develop safer formulations of insecticides of botanical origin. Different parts of the plants were chosen based on their use in countryside and villages The dried plant materials were extracted with petroleum ether, and were applied on Tribolium castaneum. The results were statistically analysed. The active principles from Croton tigilium and Leea sambucina, the most potential plants, were isolated using Column Chromatography, TLC, and Hydrolysis. The isolated principles were analysed spectroscopically ( UV-Vis., IR, NMR, and MS ) to identify their chemical nature. The active principles from Leea and Croton were identified as a cholisterate derivative and a phorbol derivative respectively. In order to ascertain the environmental combatibility of the principles, degradation by soil bacteria was studied. The isolated principles were made into three type of formulations using stabilizers .The formulations were applied on Snake gourd semilooper, Pulse beetle, and mosquito larvae. Also the biocidal activity of the formulations was studied. Both Leea derivative and Croton derivative could be formulated effectively and were effective against a variety of pests. They are eco-friendly, as there is no artificial chemicals involved. en_US
