The present study was carried out at laboratory of Entomology [SEAMEO BIOTROP] Bogor, Indonesia from June-August 2017, to estimate the insecticidal effects of different essential oils of Lemon (Citrus limon), Citronella (Cymbopogon nardus), Ginger (Zingiber Officinale), Cardamom (Elettaria cardamomum) and Cinnamom (Cinnamomum zeylanicum) against Callosobruchus maculatus under laboratory conditions. The results revealed that among the tested essential oils C. nardus was the most toxic to the adults of Callosobruchus maculatus with all concentrations after different time intervals followed by Z. officinale. E. cardamomum showed minimum population reduction percentage at all the given concentrations after different time intervals. Citrus limon and C. zeylanicum at given concentrations after different time intervals showed moderate population reduction of C. maculatus. Present findings concluded that all the tested essential oils showed better results against storage pest C. maculatus so all above mentioned essential oils can be used against storage pest as a better control measure.
