Despite being successful in preventing pests from entering stored goods, residual synthetic pesticides have had a negative impact on the environment. However, the prohibitive cost of synthetic pesticides and the risk of target pests developing insecticide resistance have prompted researchers to develop alternative management strategies. Since plant-based pesticides are biodegradable and less dangerous for organisms other than the target species, they are a useful alternative to chemical pesticides. The aim of the present study was to investigate the effectiveness of plant extract in preventing the rice weevil Sitophilus oryzae (Linnaeous) (Coloptera: Curcolinidae) from infesting stored-products. For toxicity and synergism against S. oryzae, aqueous extracts of Cannabis sative L., Dodonaea visicosa L., and Parthenium hysterophorus L., were evaluated at different concentrations. D. viscosa and P. hysterophorus extract concentrations were 0.25, 0.5, 1.0, 2.0, and 3.0%, and C. sativa extract concentrations were 0.62, 1.25, 2.5, 5.0, and 7.5%. A completely random design with three replications was used, with distilled water serving as the control. The experimental setting was kept at 27± 2oC and 65±5% R.H. The findings showed that D. visicosa, P. hysterophorus</i&...
