经3年的研究结果,危害杨梅果实的主要害虫是黑尾果蝇,被害果率达60％以上。该害虫繁殖速度快,世代重叠,历期短。在室温21～25℃、湿度75％～85％条件下饲养5代表明,黑尾果蝇世代历期4～7天,其中成虫1.5～2.5天,卵1～2天,幼虫0.6～0.7天,蛹1.1～2.1天。在杨梅果实进入第一高峰生长期开始,用敌百虫、香蕉、蜂蜜、食醋以10∶10∶6∶3比例配制成诱饵,防治试验区每 After 3 years of research results, the main pests endanger the fruit of Myrica rubra is black tail flies, fruit damage rate of more than 60%. The pests reproduce fast, overlapping generations, short duration. Five generations were kept under the conditions of 21-25 ℃ and 75% -85% room temperature. The generation age of Drosophila melanogaster was between 4 and 7 days, of which 1.5 to 2.5 days for adults, 1 to 2 days for eggs and 0.6 to 0.7 days for larvae , Pupa 1.1 ~ 2.1 days. In the first peak of bayberry fruit into the growing period, with trichlorfon, bananas, honey, vinegar at a ratio of 10:10:6:3 formulated as a bait, control test area every
