摘　　要：【目的】评价不同植物挥发物对烟蓟马Thrips tabaci雌性成虫的行为调控作用,解析烟蓟马成虫嗅觉识别行为,为研发成虫引诱剂或驱避剂提供科学依据。【方法】利用嗅觉行为测定装置测试烟蓟马雌性成虫对不同种类、不同浓度植物挥发物的室内选择行为,筛选出具有高引诱或驱避活性的挥发物。【结果】与溶剂正己烷相比,烟蓟马雌性成虫对浓度为1µg/µL的γ-癸酸内酯、(+)α-蒎烯、芳樟醇、2-乙酸苯乙酯、(-)α-蒎烯没有显著的行为选择(P>0.05),而壬醛、马鞭草烯酮、香茅醛、橙花醇和桉树脑对烟蓟马表现出显著的吸引作用(P<0.05),4-乙酰吡啶、邻茴香醛、δ-癸酸内酯、顺-3-己烯醇、香叶醇和1-辛烯-3-醇的吸引作用极显著(P<0.001);但水杨醛、香芹酚、顺茉莉醛、丁香酚和对烯丙基苯甲醚对烟蓟马表现出显著的驱避作用(P<0.05),水杨酸甲酯、茉莉酸甲酯、百里酚和异戊醛4种挥发物具有极显著的驱避作用(P<0.001)。同时,随着测试浓度的增加,大部分挥发物对烟蓟马雌性成虫的吸引或驱避作用明显增强。【结论】δ-癸酸内酯、香叶醇、1-辛烯-3-醇、邻茴香醛和4-乙酰吡啶对烟蓟马雌性成虫具有强烈吸引作用,水杨酸甲酯、茉莉酸甲酯和百里酚则具有明显驱避效应,为开发烟蓟马行为调控剂奠定了重要基础。[Objectives]To evaluate the preferences of female Thrips tabaci for different plant volatiles and thereby provide a basis for developing candidate attractants,or repellents,for this pest.[Methods]The preferences of adult female T.tabaci for different plant volatiles at a concentration of 1µg/µL were determined in an olfactometer,and the effects of different concentrations of these volatiles were also evaluated.[Results]Females displayed no significant preference forγ-decanolactone,(+)-α-pinene,linalool,2-phenylethyl acetate or(-)-α-pinene,compared to the n-hexane solvent control at a concentration of 1µg/µL(P>0.05).However,they displayed clear preferences for the other 20 volatiles.Nonanal,(S)-(-)-verbenone,(±)-citronellal,nerol and 1,8-cineole were significantly attractive(P<0.05),whereas 4-acetylpyridine,o-anisaldehyde,δ-decanolactone,(Z)-3-hexenol,geraniol and 1-octen-3-ol were even more attractive(P<0.001).Salicylaldehyde,carvacrol,(Z)-jasmone,eugenol and allylanisole were significantly repellent to females(P<0.05),whereas methyl salicylate,methyl jasmonate,thymol and isovaleraldehyde were even more repellent(P<0.001).The attractiveness,or repellence,of most volatiles had a significant upward trend with increasing concentration,and the intensity of behavioral responses was closely related to volatile concentration.[Conclusion]δ-decanolactone,geraniol,1-octen-3-ol,o-anisaldehyde and 4-acetylpyridine have potential for development as attractants of T.tabaci,whereas methyl salicylate,methyl jasmonate and thymol are potential repellents.The results provide a basis for developing environmentally friendly methods for controlling T.tabaci.
