【摘要】 经３年（１９９５～１９９７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。在室内温度２１～２５℃、湿度７５％～８５％条件下饲养五代表明，黑尾果蝇世代历期４～７ｄ，其中成虫１５～２５ｄ，卵１～２ｄ，幼虫０６～０７ｄ，蛹１１～２１ｄ。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６６６７ｍ２投放１０份诱饵诱杀，到杨梅采收期进行防治效果测定，结果表明防治区危害果率仅４％。更多还原

【Abstract】 Through 3 years′ investigation,it is known that Drosophila melanogaster is main injurious insect to red bayberry ( Myrica rubra ),and causes a damage more than 60% to the fruit.Under the temperature of 21～25℃and humidity of 75%～85%, life span of the insect is 4～7days which contains adult stage 1.5～2.5 days,egg 1～2 days,juvenila 0.6～0.7 day and pupa 1.1～2.1 days.This insect shows the properties of rapid reproduction,overlapping generations and short life cycle.The mixed bait of dipterex,banana,honey and vinegar with a ratio of 10∶10∶6∶3 was made up and 10 portions per 667m 2 was put in the field test plot during the first rapid growth period of bayberry.The percentage of damaged bayberry decreases to 4%.The effect of bait is significantly better than CK.更多还原
