摘要
采用1.8%阿维菌素、50 000 IU·mg-1苏云金杆菌、3%高渗苯氧威、1%苦参碱四种生物药剂防治榆紫叶甲成虫,并对防治效果进行对比,结果表明:施用4种生物药剂7 d后校正死亡率分别为84.22%、80.44%、95.42%和99.30%,3%高渗苯氧威和1%苦参碱对榆紫叶甲成虫有相对突出的防治效果和速效性。
Ambrostoma quadriimpressum adult was controlled with 1. 8 % abamectin,50 000 IU·mg-1bacillus thuringiensis,3 % hypertonic fenoxycarb,1 % matrine 4 kinds of biological agents and the control effect was compared. The result showed that the corrected death rate were 84. 22 %,80. 44 %,95. 42 % and 99. 30 % respectively by carrying 4 kinds of biological agents after 7 days. The 3 % hypertonic fenoxycarb and 1 % matrine had relatively prominent control effect and fast-acting property for Ambrostoma quadriimpressum adult.
