| 摘 要： | 柳蜷叶丝角叶蜂Phyllocolpa sp.是近年在甘肃天水发现的一种新害虫,严重危害多种柳属植物。1年发生1代,以老熟幼虫在表土1-5 cm中结茧越夏越冬。幼虫食柳芽及芽尖内层组织,造成其外层被干枯芽尖蜷束,叶片弯曲变形形成虫苞,每年4月上旬至5月上旬为猖獗危害期。用1.8%阿维菌素乳油和25%灭幼脲Ⅲ号胶悬剂2 000倍液喷冠防治3龄前小幼虫,防效分别为92.8%、95.2%;用3%高渗苯氧威乳油4 000倍液喷冠防治3龄后大幼虫,防效为96.7%。

| Abstract: | Phyllocolpa sp.is a serious pest of willow in Tianshui,Gansu Provunce.It has one generation per year and over winters as prepupa in cocoon in the topsil.The larvae occur from early April to early May.The trees were seriously damaged in this period.The control effects were 95.2% and 92.8% with 1.8% Abameotin and 25% Chlorbenzuron at 2 000 times before the third instar larvae. The control effect were 96.7% with 3% Fenoxycarb at 3 000 times after the third instar larvae. |
