柳枝瘿潜蝇Hexomyzasimplicoides(Hendel)在豫南一年1代,以2龄幼虫在潜道中越冬。4月上中旬3龄幼虫老熟化蛹,4月下旬至6月上旬为成虫期。成虫补充营养,在枝梢叶基芽苞周围皮层下产卵,引发多片黑褐色皮伤。幼虫蛀食形成层和韧皮部,引起皮层组织增生膨胀成瘿。4-7月引起柳树枝梢千孔百疮或枯死。卵孵化期、幼虫取食期于树根基注药和老熟幼虫化蛹期于枝梢喷药,防治效果均达95%。5月下旬至6月上旬应保护天敌柳枝潜蝇金小蜂和长尾金小蜂
Six-year-old larvae of Hexomyzasimplicoides (Hendel) winters in the submarine for 1 generation a year in south Henan. The third instar larvae mature in mid-April and adult pupae in late April to early June. Adult nutritional supplements, in the shoots around the leaf buds budding spawning, causing multiple dark brown skin wounds. Larvae eaten by the formation of layers and phloem, causing cortical hyperplasia swelling into 瘿. April to July caused thousands of perfused willow branches or dead. Egg hatching period, feeding larvae in the root-based drug injection and mature larvae pupal stage spraying in the shoots, the control effect of up to 95%. Late May to early June should protect the native enemy willow insects Potamoacanthum and long tail gold bee
