Pulse beetle (Callosobruchus chinensis L.) invasion results qualitative and quantitative losses of chickpea seeds during storage. Most of the synthetic chemicals used as preservative are having adverse effects. Therefore, insecticidal potential of Lantana camara L. essential oil (LcEO) was evaluated to find out an eco-friendly substitute of synthetic pesticides. The chemical profile of LcEO exhibited 31 known components. Germacrene-D (37.12%) was found as major component followed by β-Caryophyllene (25.18%) and Germacrene-B (16.35%). LcEO oil showed potent insecticidal activity against C. chinensis at different concentrations and exposure time. The oviposition by C. chinensis was completely checked at 10 µl L-1 while F1 emergence was completely inhibited at 200 µl L-1. During in situ experiments, 94.05% protection of the chickpea from C. chinensis by LcEO showed superiority over organophosphate insecticide malathion where 90.75% protection was recorded. The LcEO showing potent insecticidal efficacy and may be recommended as plant based preservative in the management of insect infestation of chickpea and other pulses during storage.
