The present study aimed to evaluate the antifeedant and larvicidal efficacy of the ethanol and hexane extracts of leaves and seeds of the Pongamia pinnata (Indian beech tree) plant. The research was conducted in the entomology laboratory of the Department of Zoology at Osmania University from July to November 2022. The fourth instar larvae of the Lime butterfly (Papilio demoleus), a significant pest causing damage to citrus orchards, were used as the test insect in the study. The ethanol and hexane extracts were obtained from the dried leaves and seeds of P. pinnata and were used to prepare test solutions at different concentrations. The larvicidal bioassays were conducted using leaf spray and topical application methods. The results showed that the ethanol and hexane extracts of leaves and seeds of P. pinnata have larvicidal activity against the fourth instar larvae of P. demoleus, with the ethanol extract of the leaves having the highest efficacy. The results were analyzed using a one-way analysis of variance and expressed as mean ± standard deviation. The study highlights the potential of P. pinnata as a novel biopesticide in integrated pest management and suggests that more research is needed in this field to discover novel methods in pest management.
