中文摘要：
【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1 µg/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。
英文摘要：
[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 1 µg/µL were determined in an olfactometer, and the effects of different concentrations of these volatiles were also
evaluated. [Results] Females displayed no significant preference
for γ-decanolactone, (+)-α-pinene, linalool,
2-phenylethyl acetate or (-)-α-pinene, compared to the n-hexane solvent control
at a concentration of 1 µg/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.
