Abstract

ABSTRACT National rice demand continues to increase in line with population growth, but storage faces challenges from post-harvest pests such as Sitophilus oryzae, Tribolium castaneum, and Oryzaephilus surinamensis, which reduce rice quality and quantity. The use of synthetic pesticides has a negative impact on the environment and health, so environmentally friendly alternatives are needed. One of them is the use of plant-based pesticides from soursop plants that contain bioactive compounds as pest control agents. This research aims to evaluate the effectiveness of soursop leaf extract in repelling and killing post-harvest pests. The research used a completely randomized design (CRD) with the tested factors being the concentration of soursop leaf extract consisting of 0%, 0.5%, 1%, 2%, 4%, and 8% (w/v). The results showed that soursop leaf extract was effective and could repel and kill the imagoes of Sitophilus oryzae, Tribolium castaneum, and Oryzaephilus surinamensis. The highest repellency and mortality effects were observed at the 8% concentration, which exceeded 50%. This soursop leaf extract has potential as a natural insecticide. Keywords: Oryzaephilus surinamensis, Rejection Activity, Sitophilus oryzae, Toxicity, Tribolium castaneum.
