Stored-product beetles, particularly Callosobruchus maculatus (Fabricius), are among the most destructive pests of stored legumes, causing significant quantitative and qualitative losses during storage. The widespread use of synthetic insecticides for bruchid management has led to concerns regarding insect resistance, pesticide residues, environmental contamination, and human health risks, thereby creating a need for safer and more sustainable alternatives. Botanical insecticides have emerged as promising eco-friendly options because of their biodegradability, availability, and diverse bioactive compounds with insecticidal, repellent, and fumigant properties. Pigeon pea (Cajanus cajan L. Millsp.) is an important pulse crop widely cultivated in tropical and subtropical regions, particularly in India, where it serves as a major source of dietary protein and contributes to soil fertility through biological nitrogen fixation. However, its storage is severely affected by C. maculatus, resulting in reduced seed quality, weight loss, and decreased market value. The present study was undertaken to evaluate the insecticidal potential of Curcuma longa (turmeric) and Mentha spicata (spearmint) against C. maculatus infesting stored pigeon pea. The study focuses on the efficacy of phytochemicals present in these botanicals as sustainable alternatives to conventional chemical insecticides. By assessing their potential in managing pulse beetle infestations, the research aims to contribute to the development of environmentally friendly and economically viable pest management strategies for the protection of stored legumes and the enhancement of food security.
