Abstract: The larvicidal, adulticidal, anti-feedant and oviposition deterrent activities of extracts of Glossocardia bosvallia were evaluated against stored product pests Callosobruchus chinensis, Corcyra cephalonica and Tribolium castaneum. Authenticated plant material was successively extracted with hexane, ethanol and water using ASE 100 accelerated solvent extractor (Dionex, Vienna, Austria). Of the three extracts assessed, hexane extract exhibited highly significant insecticidal and larvicidal effects to 3 stored grains pests. It has significantly (p < 0.001) suppressed adult emergence at doses of 30 and 60 mg/mL in wheat grains for C. cephalonica and T. castaneum and in green gram for C. chinensis. Furthermore, hexane extract at concentrations of 30 and 60 mg/mL significantly (p<0.001) reduced the growth rate, food consumption and food utilization indicating significant anti-feedent activity against C. cephalonica and T. castaneum. Commercially available plant based insecticide Neemarch® was used as standard. The trend of toxicity intensity was as: hexane > ethanol > water extract. Therefore, present study provides first report on the larvicidal and insecticidal activities of the plant extracts of G. bosvallia against three stored grain pest species from India.
