The study aimed to assess the larvicidal efficacy of Tamarindus indica and Citrus sinensis extracts against Tribolium castaneum, a significant pest of stored products. Adult stages of T. castaneum were collected and reared on pre-damaged rice grains under controlled conditions. Mature leaves of T. indica and C. sinensis were collected, shade-dried, powdered, and extracted using methanol. Stock solutions were prepared and diluted to concentrations of 62.5, 125, 250, and 500 ppm. Toxicity bioassays were conducted using clean plastic bottles, each containing 50 grams of wheat flour and 50 adults of T. castaneum. Filter papers soaked in test solutions were affixed to the bottle caps. Insect mortality was observed for four days, and data were analyzed using MS Excel for statistical and regression analysis.
