不同杀虫剂对角蜡蚧的防治效果研究

Control Efficiencies of Different Pesticides Against Ceroplastes ceriferus

用喷雾和涂干方法使用不同药剂开展防治角蜡蚧试验。结果表明,喷洒15%噻嗪酮·5%杀扑磷、飘绿蚧止、吡虫啉以及吡虫啉+阿维菌素和噻15%嗪酮·5%杀扑磷+哒螨·矿物油溶液对角蜡蚧防治效果不理想,死亡率和防治效果均低于50%;用杀扑磷1份与废机油100份混合后涂干防治取得良好的效果,蚧虫死亡率为97.33%,防治效果达97.28%。

The research uses chemical spray and trunk-smeared control with different pesticides to evaluate control efficiencies against Ceroplastes ceriferus. The results show that buprofezin（15%）-methidathion（5%）,chlorpyrifos, midacloprid, mixture of midacloprid and avermectins, and mixture of buprofezin（15%）-methidathion（5%） and mite-mineral oil are ineffective to Ceroplastes ceriferus because of mortalities and prevention effects being less than 50%, while mixture of wasted machine oil/methidathion（100：1 v/v） exhibits high control efficiency to the trunk-smeared samples. The mortality of the mite and the control efficiency are 97.33% and 97.28%, respectively.
