为有效控制木薯园蛴螬的危害,筛选其药剂防治技术。采用“Z”字型取样法对云南木薯园蛴螬种类进行调查,结果表明:危害当地木薯的主要地下害虫种类为痣鳞鳃金龟。选取3种药剂不同配比及浓度,采用土壤药剂处理方法进行田间药效试验,试验结果表明:“40%辛硫磷乳油2 520 m L/hm2与1.8%阿维菌素乳油1 680 m L/hm2混合液”对蛴螬有较好的防效,显著降低了植株死亡率、虫薯率和虫害率,增产幅度较大,可作为木薯蛴螬药剂防治技术推广应用。
In order to effectively control the harm of cassava garden shrews, its chemical control technology was screened. The “Z” font sampling method was used to investigate the species of 蛴 螬 in Yunnan cassava garden. The results showed that the main underground pest species that endanger the local cassava were the ichthyosis. The results showed that: “40% phoxim 2 520 m L / hm2 and 1.8% abamectin EC 1 680 m L / hm2 mixture ”has a good control effect on 蛴 螬, significantly reducing plant mortality, insect and potato rates and pest rates, yield more, can be used as cassava 螬 螬 agent control technology promotion and application.
