以切洞堵洞法分别对山西省芮城县果园间作麦田和普通麦田不同月份的棕色田鼠密度进行调查,开展了0.005%溴敌隆毒饵和溴鼠灵毒饵防治棕色田鼠大田对比试验。研究表明,每年3~4月是该区棕色田鼠的发生盛期。果园间作麦田鼠密度极显著地高于普通麦田。3—4月以溴鼠灵、澳敌隆两种杀鼠剂对棕色田鼠进行防治均有较高防效,两者灭鼠效果无显著性差异,因药剂成本不同,溴敌隆用于大面积药剂防治棕色田鼠更为适宜。
To investigate the density of brown vole in different months in orchard intercropping wheat field and ordinary wheat field in Ruicheng County of Shanxi Province, the contrastive tests of 0.005% bromadiolone bait and brodifacoum bait were conducted to control brown field vole. Studies have shown that from March to April each year is the peak of the occurrence of the field vole. Orchard inter-crop rodent density was significantly higher than the average wheat field. From April to April, the control efficacy of Bromhodrine and Oroxal against rodents was better than that of control. The rodenticidal effects of the two rodents were not significantly different. Because of the different cost of drugs, Area Pharmacy control brown vole more appropriate.
