India's population explosion has created a huge demand for vast amounts of food. Crop cultivation is just as vital as crop storage. Indian farmers' biggest concern, as the world's second-largest producer of agricultural products, is protecting their crops from grubs and adult pests. Pesticides used against them can cause a variety of acute toxicities, endocrine disorders, and even death as cancer-causing chemicals. Hence, in the present investigation the solvent extract of highly medicinal value of the plant Anisomeles malabarica was tested against azuki bean weevil Callosobrunchus maculatus. The extract was tested with different concentrations against C. maculatus. Result observed from the experiments found that ethanol extract of A. malabarica was more effective for insecticidal, repellent and ovicidal activities. The maximum ovicidal, insecticidal and repellency activity of 93.8%, 91.2% and 95.4% was noted in 96 hrs against C. maculatus. The study recommended using A. malabarica for more valuable effective control of C. maculatus as an alternative agent to artificial pesticides. The greatest option for them is to investigate and use resources derived from natural resources, such as biopesticides.
