(Walker) (Diptera: Tephritidae) is a pest seriously harmful to Solanaceae crops and was found to oviposit on the pepino melon (Aiton). To date, the differences in the ability of the fruits of and other Solanaceae crops to attract gravid females have seldom been reported. Oviposition and trapping bioassays were performed to clarify whether such differences existed. A combination of GC-MS and the Y-tube olfactometer system was used to identify and determine the compounds inducing behavioral responses in gravid females to the volatile odors of . The results show that odors play a role in attracting gravid females. The odors of Solanaceae crops influence their ability to attract these organisms. The nine compounds from the volatiles of induce tendency or repellency responses in gravid females. Hexyl acetate, butyl acetate, amyl actate, and isoamyl acetate caused tendency behavior in gravid females, while hexyl hexanoate, butyl isovalerate, butyl valerate, and isoamyl hexanoate caused repellency behavior. Heptyl acetate caused repellency behavior in gravid females at higher concentrations (5 mg/mL) but caused tendency behavior at a low concentration (0.5 mg/mL). These results suggest that vigilance against the harm caused by is required during the cultivation of . The nine compounds of the volatile odors of could help to develop attractants and repellents for gravid females. These results are beneficial for preventing females from harming , developing attractants and repellents for females, and establishing a system of ecological control for females.
沃克实蝇（双翅目：实蝇科）是一种对茄科作物危害严重的害虫，已发现其在番木瓜（艾顿）上产卵。迄今为止，关于番木瓜果实与其他茄科作物果实吸引孕卵沃克实蝇雌虫能力的差异鲜有报道。进行了产卵和诱捕生物测定，以阐明是否存在此类差异。采用气相色谱 - 质谱联用仪和Y型嗅觉仪系统，鉴定并确定诱导孕卵沃克实蝇雌虫对番木瓜挥发性气味产生行为反应的化合物。结果表明，番木瓜气味在吸引孕卵沃克实蝇雌虫方面发挥作用。茄科作物的气味影响其吸引这些生物的能力。番木瓜挥发物中的9种化合物在孕卵沃克实蝇雌虫中引发趋向或驱避反应。乙酸己酯、乙酸丁酯、乳酸戊酯和乙酸异戊酯在孕卵沃克实蝇雌虫中引起趋向行为，而己酸己酯、异戊酸丁酯、戊酸丁酯和己酸异戊酯引起驱避行为。乙酸庚酯在高浓度（5毫克/毫升）时在孕卵沃克实蝇雌虫中引起驱避行为，但在低浓度（0.5毫克/毫升）时引起趋向行为。这些结果表明，在番木瓜种植过程中需要警惕沃克实蝇造成的危害。番木瓜挥发性气味的9种化合物有助于开发针对孕卵沃克实蝇雌虫的引诱剂和驱避剂。这些结果有利于防止沃克实蝇雌虫危害番木瓜、开发针对沃克实蝇雌虫的引诱剂和驱避剂以及建立沃克实蝇雌虫的生态防治体系。
