摘要: 利用“Y”型嗅觉仪测定了14种植物挥发物对烟粉虱成虫Bemisia tataci EMD隐种的作用。结果表明,10%的1,8-桉树脑、丁香酚、月桂烯、苎烯和肉桂醛引诱作用较强,其中1,8-桉树脑和月桂烯效果最好(P<0.001)。而顺-3-已烯-醇蒎烯和戊烯为趋避作用,其中顺-3-已烯-醇蒎烯趋避性最强;1%的1,8-桉树脑、丁香酚、月桂烯、烟酸乙酯和橙花醇引诱作用显著,其中1,8-桉树脑和丁香酚的效果最好(P<0.01)。顺-3-已烯-醇蒎烯和戊烯为趋避作用,二者之间无显著差异;将有引诱作用的单体复配后,仅1,8-桉树脑+丁香酚(1:1)和1,8-桉树脑+月桂烯(1:1)有引诱作用;10%的1,8-桉树脑涂抹黄板显著提高了黄板诱杀力。因此,植物挥发物对烟粉虱有趋避或引诱作用,其作用因浓度而发生改变,趋性一致的复配后不一定能发挥原有作用。

Abstract: The behavioral responses of Bemisia tabaci MED adults to volatile compounds of 14 plants were determined using Y-tube olfactometer. Using different combinations of plant volatiles and yellow sticky trap, the optimum combinations of plant volatiles and yellow sticky trap were evaluated by comparing the trapping catches of B. tabaci adults. Ten percent of 1,8-cineole, eugenol, myrcene, limonene and cinnamaldehyde showed attractiveness to adults of B. tabaci, 1,8-cineole and myrcene being significantly effective (P<0.001). While cis-3-hexene-ol pinene and pentene showed repellency, cis-3-hexene-ol pinene being stronger. At 1%, 1,8-cineole, eugenol, myrcene, ethyl nicotinate and nerol were attractive to B. tabaci adults significant in 1,8-cineole and eugenol (P<0.01). In contrast, repellency response to cis-3-hexene-ol pinene and pentene was detected. The combination of 10% 1,8-cineole+eugenol (at 1:1) and 1,8-cineole+myrcene showed relatively better attractiveness to B. tabaci. Meanwhile, in the field experiment, yellow sticky trap coated with 10% 1,8-cineole caught more B. tabaci. Our results show that plants volatiles can be effective attractant or repellent for B. tabaci, and the taxis response of B. tabaci to the same monomeric compound varies with compound concentration. Besides, pairwise mixing of monomeric compounds with consistent taxis response may not necessarily play the original role of taxis responses of the monomeric compound.
