Methyl eugenol (ME) is knownto be a powerful attractant to the oriental fruit fly, Bactrocera dorsalis (Hendel), and its complex of species. Monthly distribution of 2 fiber blocks (4.5 by 4.5 by 0.9cm) baited with 10g of poisoned ME per hectare resulted in complete eradication of oriental fruit fly populations on the isolated islands of Okinawa, Japan. Eradication was accomplished on each island within a year or so. This is contrasted to other male lures such as cue lure and trimedlure. So the question is why is methyl eugenol is so effective as compared with other fruit fly lures. Toanswer this question, the attractiveness of methyl eugenol (ME) to Bactrocera carambolae (Drew & Hancock), which is a species of the B.borsalis complex, was examined in Indonesia. Approximately 600 newly emerged males and females were released into an outdoor screen cage when they were 2 days old. An MEtrap, a potted carambola fruit tree, Averrhoa carambola L., and adult food were placed in the screen cage. Males began to respond to ME immediatrly after release. At least 2 males mated with females during exposure to ME,whereas>99% of the males were recorded as dead by trapping or other factors. These results indicate that most males respond to ME before they become sexually mature. some factors which may enhance the efficiency of ME were discussed.

甲基丁香酚（ME）是一种对东方实蝇（Bactrocera dorsalis（Hendel））及其复合种群有强烈引诱作用的物质。在日本冲绳，每月投放2个纤维块（4.5 × 4.5 × 0.9cm），每公顷10g毒饵，可完全消灭东方实蝇种群。每一个岛屿都在一年左右的时间内完成了根除工作。这与其他雄性诱饵，如cue lure和trimedlure形成对比。所以问题是，为什么甲基丁香酚与其他果蝇诱饵相比如此有效。为了回答这个问题，甲基丁香酚（ME）的吸引力，杨桃（德鲁和汉考克），这是一个物种的B.borsalis复杂，在印度尼西亚进行了检查。大约600只新出现的雄性和雌性在2天大时被释放到户外屏幕笼中。一种盆栽杨桃果树，杨桃，和成虫的食物被放置在筛笼中。雄性在释放后立即开始对ME作出反应。在暴露于ME期间，至少有2只雄性与雌性交配，而>99%的雄性被记录为因诱捕或其他因素而死亡。这些结果表明，大多数男性在性成熟之前对ME有反应。讨论了提高微电解效率的一些因素。
