India, as the world's second-largest producer of fruits and vegetables, faces significant challenges from pests affecting its citrus crops. The Lime butterfly (Papilio demoleus) poses a serious threat, with its larvae causing extensive damage to citrus leaves. To manage these pests, the reliance on chemical pesticides is high, but their overuse has led to environmental pollution, biodiversity loss, and health hazards. As an alternative, plant-based biopesticides have emerged as a promising solution. This study investigates the larvicidal efficacy of extracts from Momordica charantia (bitter melon) and Cinnamomum verum (cinnamon) against P. demoleus larvae.
