Bionomics and control of the root maggot,Bradysia odoriphaga,infested on the watermelon

韭菜迟眼蕈蚊Bradysia odoriphaga Yanget Zhang危害西瓜早春红玉幼苗的现象尚未见报道。观察记录韭菜迟眼蕈蚊以瓜类植物饲养的发育历期并进行田间药剂防治试验。结果表明:瓜类植物饲养条件下的韭菜迟眼蕈蚊幼虫发育历期与已报道的以韭菜饲养条件下的发育历期基本一致,50%灭蝇胺可湿性粉剂和10%吡虫啉可湿性粉剂1500倍防治韭菜迟眼蕈蚊效果较好,保苗率达97%。

The root maggot, Bradysia odoriphaga Yang et Zhang, is one of the most important pests of Chinese chives （Allium tuberosum ）. However it has been found on an early matured and small-sized watermelon variety, named as Zao Chun Hong Yu in Caidian District, Huhei Province. Its life history, living habits and control methods were briefly introduced in this paper and they are similar to those inf on Chinese chives.
