Man suffers extensively due to the nuisance of insect populations both in agriculture and health. In agriculture, insects affect directly the growing part of the crop and causes severe damage, resulting in revenue loss. Crop loss due to insect pests is estimated between 10 and 30% for major crops. In a tropical country like India, owing to climatic conditions and its particular environment, agriculture is suffering from severe losses due to pests. Considering the agro-ecosystems with an increase in population and dwindling land resources there is worldwide demand for natural insecticides to increase the agriculture production. Due to these problems, a search is going on to discover new, less damaging pest management tools. The present investigation was undertaken with the objective to evaluate the potential of different medicinal T. malabarica (Lam.) Miers (Menispermaceae) extracts against antifeedant activity of S. litura. Hexane, diethyl ether, dichloromethane, ethyl acetate and methanol extracts T. malabarica AFI50 and AFI90 values were 258.71, 251.80, 234.97, 220.57, 196.53 and 398.17, 376.12, 346.25, 322.02 and 316.40 ppm respectively. This study proposed plant chemicals from T. malabarica by the green chemistry approach using controlling the economically important pests alternate to synthetic pesticides.
