摘要
从天然植物中提取的挥发油经初步试验筛选出 8种杀虫效果突出的植物 ,以黄樟油、肉桂油、八角油对试虫 (玉米象、谷蠹和赤拟谷盗 )作用方式的测定发现 ,这些植物挥发油具有强烈的熏杀和触杀作用 ,而且具有用量低 ,致死作用迅速等特点。用植物挥发油拌粮不但能杀灭当代害虫 ,而且能完全控制子代的发生。植物挥发油的驱避作用较强 ,经持续 4周试验后其驱避率仍能保持在 80 %左右。这些植物性物质来源广泛 ,可直接应用于谷物、种子、饲料等储藏物害虫的防治。具有广泛的应用前景。
Efficacy of Cinnamoum camphora oil, Chinese cinnamon oil and Luicium verum oil which were selected from eight plant volatile oils against the stored grain instcts ( Sitophilus zeamais,Rhizopertha dominica,Tribolium confusum) was studied.The tests showed that the plant volatile oils were the fumigants and had contact toxicity,the insects died rapidly.The volatile oils can not only kill the present insects,but also can control occurance of progeny.The volatile oils had a strenthen repellency.About 80% repellency rate was still retained through 4 weeks.
