Repellent activity of cinnamaldehyde was compared against its two structural analogs (methyl cinnamate and ethyl cinnamate), and repellent effect of cinnamaldehyde formulated in agaro-pectin was also determined. Results in Y-typed olfactometer showed that the Cinnamomun cassia bark powder and Syringa oblata bud powder had extremely significant repellent effect, and repellent activity of three tested compounds was expressed in a declining order of cinnamaldehyde, methyl cinnamate and ethyl cinnamate. Results in basin-shaped olfactometer showed that repellent index of cinnamaldehyde formulated in agaro-pectin almost reached 100% against Lasioderma serricorne during a four-day test period. Thus cinnamaldehyde as component of tobacco flavor could be used to make agaro-pectin repellent against Lasioderma serricorne in tobacco warehouse. Keywords:
