人工梭梭林大沙鼠防治药剂筛选试验

Screening Experiment of Control Agents for Rhombomys opimus in Artificial Haloxylon ammodendron Forests

为了减少大沙鼠对梭梭林的危害程度,以金塔县人工梭梭林中的大沙鼠为研究对象,选取4种药剂,开展了防治大沙鼠的药剂筛选试验。结果表明:0.25 mg·kg^(-1)雷公藤甲素颗粒剂防治效果最佳,校正灭洞率为78.20%;其次是0.02%溴敌隆毒饵剂和20.02%地芬.硫酸钡饵剂,校正灭洞率分别为69.54%、65.48%;CO灭鼠烟包防治效果最不理想,校正灭洞率仅为16.47%。在生产中建议使用生物源药剂0.25 mg·kg^(-1)雷公藤甲素颗粒剂和20.02%地芬·硫酸钡饵剂,这两种药剂防治效果好,符合当前绿色防治理念,对环境污染小,不会破坏生态平衡,不容易产生抗药性。

In order to protect the ecological environment and reduce the harmful consequences of Rhombomys opimus to the Haloxylon ammodendron forest,four types of pesticides were selected and a screening experiment was conducted for the control of Rhombomys opimus.Through the experiment,it was concluded that 0.25 mg·kg^(-1) Triptolide granules had the best control effect,with a corrected hole killing rate of 78.20%;followed by 0.02%bromadiolone bait and 20.02%difen barium sulfate bait,with corrected hole killing rates of 69.54%and 65.48%,respectively;Lastly,the control effect of CO rodent control cigarette packs is not ideal comparatively,with a corrected hole killing rate of only 16.47%.Above all,The use of the biosource agent 0.25 mg·kg^(-1) of triptolide granules and 20.02%dipfen barium sulfate is recommended in production.These two agents not only have good prevention and control effect,but also Eco-friendly according to the current green prevention and control concept,which will not destroy the ecological balance and not easy to produce resistance.
