摘　　要：选择17种云木香挥发物测定绿盲蝽对其电生理及行为学反应。结果表明,芳樟醇和5-羟甲基糠醛可引起绿盲蝽强烈的电生理反应,且芳樟醇对绿盲蝽雌、雄虫均具有极显著的驱避作用,选择反应率均低于40%。而5-羟甲基糠醛原液与100倍稀释液均能显著地引诱绿盲蝽,选择反应率分别为51.43%和70.59%。此外,芳樟醇原液对Q型烟粉虱驱避与5-羟甲基糠醛对其的引诱作用同样显著。将这两种化合物组合形成“推-拉”策略后,寄主上绿盲蝽和Q型烟粉虱平均虫量分别为(2.2±0.6)头和(1.9±1.0)头,粘虫板上虫量分别为(7.7±0.7)头和(21.9±1.6)头,与对照组差异显著。5-羟甲基糠醛未对赤拟谷盗表现出引诱作用,但芳樟醇驱避作用显著,选择反应率为25%。表明利用“推-拉”策略防治经济害虫具有良好应用前景。Seventeen volatiles from Aucklandia costus were selected and their electrophysiological and behavioral responses to Apolygus lucorum were tested.The results showed that linalool and 5-hydroxymethylfurfural induced strong electrophysiological response of A.lucorum;linalool had a significant repellent effect on both sexes of A.lucorum,and the selective response rates were both below 40%.5-hydroxymethylfurfural and 100-fold dilution had a significant attractive effect on A.lucorum,with a selective response rate of 51.43%and 70.59%,respectively.In addition,the repellent(linalool)and attractive effects(5-hydroxymethylfurfural)of the two compounds on Bemisia tabaci Q-biotype were also significant.After combination of the two compounds in the“push-pull”strategy,the average numbers of A.lucorum and B.tabaci on host plants were(2.2±0.6)and(1.9±1.0)individuals,respectively,and the numbers of adults on the sticky boards were(7.7±0.7)and(21.9±1.6)individuals,respectively,which showed significant differences compared with those of the control groups.5-hydroxymethylfurfural showed no attractive activity to Tribolium castaneum,whereas linalool had repellent effect with a selective response rate of 25%.It suggested that the“push-pull”strategy had a good application prospect for controlling economic pests.
