为筛选烟草甲植物源高效驱避剂，对12种芳香植物材料进行了筛选，比较了肉桂醛及其2种结构类似物（肉桂酸甲酯和肉桂酸乙酯）的驱避活性，测定了肉桂醛琼脂胶包结物的驱避效果。Y形嗅觉仪测定结果表明，肉桂皮粉和丁香粉对烟草甲具有极显著的驱避活性，3种化合物的驱避活性次序为：肉桂醛＞肉桂酸甲酯＞肉桂酸乙酯。盆形嗅觉仪测定结果表明，肉桂醛琼脂胶包结物在4 d内对烟草甲的驱避反应指数可达100%。肉桂醛是烟用香精的成分，可制作琼脂胶包结驱避剂用于烟仓中烟草甲的防治。%Twelve aroma plant species were chosen to screen effective plant repellent to tobacco beetle, Lasioderma serricorne. 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.
