摘要
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 control the hazard of grub and screen out of technology of chemical control. The cassava field grub species was surveied by sampling method of ＂ Z＂ and the result showed that the main soil insect is Lepidiota stigma Fabricius. Experiment using application method of soil mixed with 3 different proportion and concentration of pesticides were arranged in this paper.The result showed that two treatments the mixture of 40%phoxim EC（2 520 m L/hm2）and 1.8% abamectin EC（1 680 m L/hm2）degraded the rate of plant death, grub-carried root and damage, and promoted yield significantly, which is thought to can be promoted in main producing areas for grub preventing.
