Red flour beetle, Tribolium castaneum (Fabricius) (Coleoptera: Tenebrionidae) is one of the most devastating pests of stored grains. In current study, the pesticidal effect of deltamethrin and five plant extracts Nicotiana tabacum, Nicotiana rustica A. galangal Azadirachta indica and Curcuma longa was evaluated. Deltamethrin was applied at the rate of 0.001, 0.002, 0.003, 0.004, 0.005 and 0.006% while five different concentrations 0.5, 1.0, 1.5, 2.0, 2.5, and 3.0 % were used for each of the plant extracts, for 24, 48, 72 and 96 h. Four replications for each treatment were carried out adapting Completely Randomized Design (CRD). Probit analysis was used to determine the LC50 and LC90 values. In contact toxicity test, deltamethrin demonstrated the highest toxicity with 0.88 v/v and 4.74 v/v, LC50 and LC90 respectively. The plant extracts however, demonstrated the highest mortality rate after 96 h of exposure. Lowest LC50 of 1.00 g/L and LC90,5.38 g/L, was recorded for N. rustica. Next in order was N. tabacum with LC50 1.09 g/L and LC90 6.50 g/L, followed by C. longa LC50 1.33 g/L and LC90 6.89 g/L and A. indica LC50 1.46 g/L and LC90 7.43 g/L against the pest species. In residual toxicity on the other hand, deltamethrin exhibited an LC50 of 0.93v/v and LC90 3.83 v/v. Whereas, in case of plant extracts the order of toxicity in terms of lowest LC50 0.79 g/L and LC90 10.37 g/L was observed with N. rustica, followed by LC50 1.18 g/L and LC90 9.02 g/L N. tabacum and LC50 1.82 g/L and LC90 22.36 g/L, A. indica against the red flour beetle. Various groups of phytochemicals such as phenols, saponins, alkaloids, di-terpenes, flavonoids and phytol-steroids were identified in the plants species aqueous extracts. Findings in the present study suggest that N. rustica, N. tabacum, C. longa, and A. indica can be effectively utilized to control T. castaneum as well as these plant species may be useful in the development of novel bio-pesticides.

Tribolium confusum and Sitophilus oryzae are stored product pests found worldwide. Environmental damages, human health issues and the emergence of resistance are driving scientists to seek alternatives to synthetic insecticides for its control. Under this scenario, plant secondary metabolites are being increasingly studied as bioinsecticides because they are renewable, natural, biodegradable, non-persistent in the environment and safe to non-target organism and humans. In this study, the chemical composition and lethal effects of methanol extract of Capparis spinosa fruits on Tribolium confusum and Sitophilus oryzae adults were studied. The LC50 of extract on T. confusum and S. oryzae in contact method were 14.7 and 10.5 mg cm-2, respectively, whereas in the dip method, the LC50 value determined 41.3 and 34.3 mg ml-1 for T. confusum and S. oryzae, respectively. The most important identified compounds were the thymol (22.5 %), methyl sulfonyl heptyl isothiocyanate (13.3 %), butyl isothiocyanate (8.1 %), γ-terpinene (6.2%) and iso propyl isothiocyanate (5.8 %). The results confirmed the potential of the C. spinosa extract in controlling stored-product insects.

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
