Essential Oils (EO) from four different plants viz., Cinnamomum cassia ( L .) J. Presl, Foeniculum vulgare Mill ., Murraya koenigii (L.) Sprengel and Pogostemon cablin (Blanco) Benth . were tested for their efficacy by Residual film technique for toxicity and Repellency by Area preference method against adult Red Flour Beetle, Tribolium castaneum (Herbst) (Coleoptera: Tenebrionidae). The repellency was recorded as an index of repellency (IR) at 30 min, 12 and 24-h’ time point. IR at 24 h time point with 1% v/v concentration for C. cassia and P. cablin was 0.1, 0.2 for F. vulgare and 0.5 for M. koenigii. The sub-lethal concentration (LC20) in % v/v for mortality to T. castaneum after 72 h was observed as 0.172 for C. cassia, 0.345 for P. cablin, 0.632 for M. koenigii and 0.712 for F. vulgare. The median lethal concentration (LC50) in % v/v for mortality to T. castaneum after 72 h was observed as 0.098 for C. cassia, 0.123 for P. cablin, 0.427 for M. koenigii and 0.304 for F. vulgare. It indicates that the P. cablin and C. cassia oil exhibits significant repellency and C. cassia oil exhibits significant toxicity against T. castaneum. Results obtained from this study indicate the important role of botanicals may be as pesticides against stored product pests in the modern world.
