摘　　要：【目的】为开发和设计褐飞虱Nilaparvata lugens拒避剂与引诱剂提供科学依据.【方法】利用Y型嗅觉仪测定褐飞虱对20种非寄主植物释放的挥发物及对α-蒎烯、α-水芹烯、崁烯、芳樟醇的拒避与引诱行为.【结果和结论】枸树Broussonetia papyrifera、塞楝Khaya senegalensis、胜红蓟Ageratum conyzoides、蟛蜞菊Wedelia chinensis、鬼针草Bidens pilosa、马樱丹Lantana camara、桉树Eucalyptus exsetrta、毛麻楝Chukrasia tabularis的叶片和小茴香Foeniculum vulgare的种子挥发物对褐飞虱雌成虫具有显著的拒避作用,其中蟛蜞菊、塞楝和桉树叶片挥发物的拒避作用比较明显,拒避率分别为87.5%、83.3%和72.0%;洋葱Allium cepa(鳞茎)挥发物对褐飞虱具有极显著的引诱作用,引诱率为73.1%;其他植物叶片挥发物对褐飞虱的拒避与引诱行为没有显著的影响.9种植物共有的3种挥发成分在测试浓度下,α-蒎烯对褐飞虱雌成虫有显著的引诱作用,崁烯对其有显著的拒避作用,α-水芹烯则对其拒避与引诱行为没有显著影响.水稻挥发物芳樟醇因含量不同,褐飞虱雌成虫的选择行为有差异,芳樟醇用量为1μL时对褐飞虱具有显著引诱作用,10μL以上时表现为拒避作用,15μL以上均具有极显著的拒避作用.[Objective]To provide scientific evidence for the development and design of repellents and at-tractants of brown planthopper ,Nilaparvata lugens Stal （ BPH）.[Method] The repellented and attrac-tivebehaviors response of female adults BPH to volatiles of twenty non-host plants and α-phellandrene ,α-pinene ,camphene and linalool were tested by a Y-tube olfactometer .[Result and conclusion] The vola-tiles of Broussonetia papyrifera,Khaya senegalensis,Ageratum conyzoides,Wedelia chinensis,Bidens pilosa, Lantana camara, Eucalyptus exsetrta, Chukrasia tabularis, and the nuts of Foeniculum vulgare revealed repellent effects on BPH , especially, volatiles of W.chinensis,K.senegalensis and E.exsetrta showed sig-nificant repellent effects on BPH , with repellency rates 87.5%,83.3%and 72.0%respectively .Howev-er, volatiles of the bulb of Allium cepa showed significant attractive effects on BPH , with attractive rate 73.1%.The rest 10 non-host volatiles had no significant effects on BHP repellented and attractive behav-iors.Though all 3 compounds were in the volatiles of 9 repellent non-host plants, α-pinene showed at-tractive effects , while camphene had significant repellent effects on BPH , but α-phellandrene showed no＆amp;nbsp;significant effects on BPH behaviors with all tested concentrations .Furthermore , the linalool had signifi-cantly attractive effects at 1 μL, but it had repellent effects at 10 μL and significant repellent effects on BPH above 15 μL.
