Abstract: Mungbean seeds [Vigna radiata (L.)] are easily damaged by insects during storage, and essential oils (EOs) have proved effective for controlling insect infestation. This research study assessed the bioactivity of EO from Jasminum sambac (L.) Aiton against Callosobruchus maculatus (F.). The chemical composition of EO was analysed by a gas chromatograph-mass spectrometer (GC-MS). All experiments were conducted following a completely randomised design (CRD) with four replications of the residual contact and seed dressing bioassays. Results indicated that J. sambac EO contained 35 compounds (97.587%), with the main component 3-hexen-1-ol benzoate. Residual contact toxicity LC50 values of this EO on adult C. maculatus at 24, 48, and 72 h were 5.01, 4.00, and 3.13 µL/mL, respectively. J. sambac EO at 8 µL/L showed the highest residual contact efficacy against C. maculatus, killing up to 100% in 72 hours. The highest concentration of J. sambac EO (1 mL/kg) gave optimal protection against C. maculatus within 4 and 5 days with 100% mortality. This concentration showed 100% inhibition of adult F1 progeny emergence, with no seed damage and weight loss of V. radiata L. after 30 days of exposure, and not significantly different from 0.8 mL/kg. Results indicated that J. sambac EO effectively prevented C. maculatus infestation and it could be used as an alternative to commercial chemical insecticides.
