(Hendel) (Diptera: Tephritidae) is a pest fruit fly species native to Oriental Asia which has invaded and established in Hawaii and Tanzania and has been recovered in detection trapping in California. It is largely non-responsive to the male lures cuelure and methyl eugenol. Alpha-ionol + cade oil is a moderately effective male attractant, but is not as attractive as cuelure or methyl eugenol are to other fruit fly species. An improved attractant is therefore desired. With the recent success in finding other non-responsive fruit fly species attracted to isoeugenol, methyl-isoeugenol, or dihydroeugenol in Australia and other countries, we wanted to assess whether might also respond to these “eugenol analogs.” Working with wild populations in Hawaii, we assessed the relative catch of in traps baited with the eugenol analogs with catch in traps baited with alpha-ionol, alpha-ionol + cade oil, or alpha-ionol + eugenol. Catch was significantly higher in traps baited with alpha-ionol + cade oil relative to traps with any of the other baits. There was, though, some male catch in traps baited with dihydroeugenol or isoeugenol but none in traps baited with methyl-isoeugenol.
亨氏果实蝇（双翅目：实蝇科）是一种原产于东亚的有害果蝇物种，已入侵夏威夷和坦桑尼亚并在当地定殖，在加利福尼亚的检测诱捕中也被发现。它对雄性引诱剂诱蝇酮和甲基丁香酚基本无反应。α-紫罗兰醇+杜松油是一种中等有效的雄性引诱剂，但不如诱蝇酮或甲基丁香酚对其他果蝇物种有吸引力。因此，需要一种改进的引诱剂。鉴于最近在澳大利亚和其他国家发现其他对诱蝇酮、甲基丁香酚或二氢丁香酚无反应的果蝇物种被异丁香酚、甲基异丁香酚或二氢丁香酚吸引，我们想评估亨氏果实蝇是否也会对这些“丁香酚类似物”有反应。我们在夏威夷对野生亨氏果实蝇种群进行研究，评估了用丁香酚类似物诱饵诱捕的捕获量与用α-紫罗兰醇、α-紫罗兰醇+杜松油或α-紫罗兰醇+丁香酚诱饵诱捕的捕获量的相对情况。相对于使用其他任何诱饵的诱捕器，用α-紫罗兰醇+杜松油诱饵的诱捕器捕获量显著更高。不过，用二氢丁香酚或异丁香酚诱饵的诱捕器捕获到了一些雄性亨氏果实蝇，而用甲基异丁香酚诱饵的诱捕器未捕获到。
