| 摘 要： | ［目的］ 明确利用蚤蝇携带白僵菌防治松墨天牛（Monochamus alternatus）的效果。［方法］ 采用室内饲养结合室外释放的方法研究蚤蝇的生活史和生物学特性，并进行种类鉴定。采用蚤蝇携菌法、直接撒粉法等不同方法比较球孢白僵菌MA0813菌株对松墨天牛幼虫的防治效果。［结果］经形态学鉴定确认寄生松墨天牛的蚤蝇为东亚异蚤蝇（Megaselia spiracularis Schmitz）。该虫人工饲养、繁殖十分容易，活动能力强，飞行扩散超过400 m，在宁波全年发生10代，以蛹越冬。球孢白僵菌MA0813菌株滴涂法防治松墨天牛4～5龄幼虫，LD50为（0.145 5±0.110 5）×104孢子/头。菌蝇法防治松树内松墨天牛1～2龄幼虫，室内校正僵死虫率为46.4%；7月上中旬在山林中试验每隔100 m放菌蝇2次，校正僵死率达35%，优于其他防治方法。［结论］ 菌蝇法能明显提高对松墨天牛的防治效果。
