Abstract

ABSTRAC Rice is the primary staple food for the Indonesian population, making post-harvest storage a crucial stage. One of the common challenges during rice storage in warehouses is pest infestation by Sitophilus oryzae, Tribolium castaneum, and Oryzaephilus surinamensis, which can damage and reduce the quality of rice. Lime peel has potential as a botanical insecticide due to its active compounds such as flavonoids, essential oils, tannins, saponins, phenols, and alkaloids. This study was conducted experimentally in a laboratory using a Completely Randomized Design (CRD) with six concentrations of lime peel extract (0%, 0.5%, 1%, 2%, 4%, and 8%), each replicated three times, resulting in 18 experimental units. Data were analyzed using analysis of variance (ANOVA), followed by Duncan‟s Multiple Range Test (DMRT) at a 5% significance level. The results showed that repellent activity appeared one hour after application, with the 0.5% concentration already showing an effect on S. oryzae and T. castaneum, although not yet on O. surinamensis. At the highest concentration (8%), repellency increased to 35–39%. Mortality began to appear on the first day, peaking on day 7, with the highest mortality observed in T. castaneum (90%), followed by S. oryzae and O. surinamensis at 83.8%. The 8% concentration was the most effective, showing repellency and mortality rates exceeding 50%, indicating that lime peel extract holds significant potential as a botanical insecticide for natural pest control in storage environments. Keywords: Citrus aurantifolia, Oryzaephilus surinamensis, Repellent activity, Sitophilus oryzae, Toxicity, Tribolium castaneum.
