Abstract
The present research work has been carried out to find a safe and environmentally sustainable substitute of traditional synthetic insecticide to manage the Oryzaephilus surinamensis in stored split-chickpea. Seven plant leaf extracts of Datura stramonium, Mentha longifolia, Cannabis sativa, Cymbopogon citratus, Allium sativum, Allium cepa, and Brassica juncea were checked against sawtoothed grain beetle Oryzaephilus surinamensis (Coleoptera: Silvanidae). In each experiment, five concentrations of each plant leaf extract (1, 2, 3, 4 & 5 percent) were tested. Findings of this study work shown that fewer F1 adults appeared in split-chickpea when treated with the highest concentration of B. juncea relative to other treatments. Lower inhibition percentage of sawtoothed grain beetle adults was found when fed on split-chickpea treated with lowest concentration of C. citratus. Weight loss (25%) was more in split-chickpea treated with lowest concentration of C. citrarus. Results showed that B. juncea extract was the most effective causing 86.33% mortality. Maximum mortality was recorded at 72 hours as compared to 24 and 48 h. For B. juncea the lowest LC50 value 0.24, 0.18 and 0.16% for 24, 48 and 72h and it was 0.77, 0.53 and 0.36 for 24, 48 and 72h in case of A. cepa.
