摘　　要：【目的】南亚实蝇被多个国家列为检疫性害虫,其雌虫在野外被发现取食构树果实。本研究拟初步明确构树果实对南亚实蝇雌虫的引诱效果及其主要引诱成分。【方法】通过室内诱捕试验,测试构树果实对南亚实蝇雌虫的引诱效果;采用气质联用仪(GC-MS)与Y型嗅觉仪,测定构树果实中引起南亚实蝇雌虫行为反应的成分。【结果】构树果实对南亚实蝇雌虫的诱捕率高达81.11%;从构树果实气味中测定出29种挥发性成分,其中,0.500 mg·mL^(-1)的2-正戊基呋喃、0.005 mg·mL^(-1)的反-2-己烯醛和0.050 mg·mL^(-1)的正庚醛能显著引起南亚实蝇雌虫的趋向行为。【结论】构树果实具有作为南亚实蝇雌虫食诱剂的潜力,构树果实中的2-正戊基呋喃、反-2-己烯醛和正庚醛可能是引诱南亚实蝇雌虫的主要成分。【Aim】Zeugodacus tau has been listed as a quarantine pest in many countries.The females feed on the polythalamic fruits of Broussonetia papyrifera.The aims of the study were to determine the attractant effect and main attractant compounds of B.papyrifera fruit to Z.tau females.【Method】Trapping bioassays were used to determine the attractant effect of B.papyrifera fruits on Z.tau females.GC-MS(gas chromatography-mass spectrography)and Y-tube olfactometry were used to identify and determine the compounds in B.papyrifera fruits that induce behavioral responses in Z.tau females.【Result】B.papyrifera fruit could attract Z.tau females effectively,and the attractive rate was up to 81.11%.Twenty-nine compounds were identified and isolated from B.papyrifera fruit odor.Among these,2-pentyl-furan(0.500 mg·mL^(-1)),(E)-2-hexenal(0.050 mg·mL^(-1)),and heptanal(0.050 mg·mL^(-1))were effective at inducing attractive behavioral responses in Z.tau females.【Conclusion】B.papyrifera has the potential to be used as a female attractant for controlling Z.tau females.2-Pentyl-furan,(E)-2-hexenal,and heptanal may be the main components attracting female flies.
