摘　　要：实蝇可危害多种水果和葫芦科蔬菜,造成重要经济损失,生产实践中诱杀是防治实蝇最安全、有效、常用的方法。实蝇营养诱剂实蝇克(含0.05%阿维菌素)对危害苦瓜的实蝇类害虫的诱杀防治试验结果表明,实蝇克以1-20倍清水拌匀置于敞口诱食器,能有效诱集桔小实蝇、瓜实蝇等常见实蝇,其中以桔小实蝇的诱集量最大、约占70%,其次是瓜实蝇、占15%-25%,其他实蝇占5%-15%,对桔小实蝇雌虫的诱集并无明显的性别选择倾向。在实蝇高峰期,实蝇克以1-20倍清水拌匀诱捕实蝇,每隔7 d换药1次,连续换药3次,苦瓜果实带虫率可控制在5%以内,保护作用可达80%以上,效果优于或相当于商品化生产使用的物理粘杀剂。Many kinds of fruit and cucurbitaceous vegetables are infected by the fruit fly, which results in serious economic loss.
