Abstract

The red flour beetle, (Tribolium castaneum), stands as a notable primary pest, with a global presence in infesting a wide variety of stored commodities. The current investigation explores the adulticidal and larvicidal properties of oils derived from Azadirachta indica (neem) and Brassica juncea (mustard) plants. Larvicidal bioassay tests were conducted, revealing that concentrations of 13.47% and 17.67% of A. indica and B. juncea oils, respectively, resulted in 50% mortality (LC50) of the fourth instar larval stage of Tribolium castaneum. Furthermore, adulticidal activity was observed at LC50 concentrations of 22.91% and 25.16% for A. indica and B. juncea oils, respectively, against Tribolium castaneum adults. The results indicated that both A. indica and B. juncea oils exhibit significant efficacy against both the larval and adult stages of Tribolium castaneum. These findings suggest that these plant oils hold promise as potential natural insecticides for managing Tribolium castaneum infestations and present nature-friendly alternatives to synthetic pesticides. These findings indicate that the plant oils, A. indica and B. juncea, hold promising potential as natural insecticides for effectively managing Tribolium castaneum infestations. Furthermore, they present eco-friendly alternatives to synthetic pesticides.
