中文摘要：
利用Y-嗅觉仪测试不同生理状态(性成熟和性未成熟)番石榴实蝇Bactrocera correcta(Bezzi)两性成虫对系列质量分数(1%, 3%, 5%, 7%, 9% w/w)甲基丁香酚(ME)溶液、系列质量分数ME溶液与醋酒溶液(醋∶酒∶水＝12.5%∶25%∶62.5% (w/w), VA)混合液、系列质量分数ME挥发物与糖醋酒溶液(糖∶醋∶酒∶水＝2.5%∶12.5%∶25%:60%(w/w), SVA)气味混合物的反应。结果表明，质量分数在3%以上的ME溶液对性成熟和性未成熟雄虫均有显著引诱效果。饥饿状态下的4日龄性未成熟雌虫以及取食状态下的4~6日龄性未成熟雌虫均能对5%ME溶液产生显著反应。ME+VA混合液对性成熟雄虫和性未成熟雌虫均有显著引诱效果。SVA气味与5%ME溶液的挥发物混合后能显著加强5%ME溶液对性成熟雄虫的引诱效果。5%ME与SVA、7%ME与SVA的混合气味均比单一ME溶液对性未成熟雌虫有更强的引诱效果。
英文摘要： The responses of mature and immature adults of Bactrocera correcta(Bezzi) to methyl eugenol (ME) solutions at different concentrations (1%, 3%, 5%, 7%, 9%, w/w), to the mixture of ME and a sweet bait VA (12.5% vinegar, 25% alcohol and 62.5% H2O), and to the combination of the volatiles of ME solutions at different concentrations and a sweet bait SVA (2.5% sugar, 12.5% vinegar, 25% alcohol and 60% H2O) odor, were tested in Y-tube olfactometer in laboratory. The results showed that 3%~9% ME solution demonstrated significant attraction to both mature and immature males. The starved 4 day females (immature), and feeding 4~6 day females (immature) were greatly attracted to 5% ME solution. The mixture of ME and VA showed significant attraction to mature males and immature females. More mature males were attracted to the combination of volatiles of 5% ME solution and SVA ordor than to only 5% ME solution. Similarly, the mixture of 5% ME volatiles and SVA odor, and 7% ME volatiles and SVA odor were both more attractive to immature females than ME solution volatiles alone.
