广西部分大型水电站库区灭鼠效果评价

目的研究大型水电站库区大面积灭鼠的方法，为今后灭鼠工作提供科学依据。方法平班水电站淹没区的室内采用0．1％敌鼠钠盐稻谷毒饵，室外采用0．005％溴敌隆稻谷毒饵进行灭鼠；百色水利枢纽、恶滩水电站和长洲水利枢纽库区的室内外均采用0．005％溴敌隆稻谷毒饵进行灭鼠；龙滩水电站库区的室内外采用O．0375％杀鼠迷小麦毒饵灭鼠。结果平班水电站、百色水利枢纽、恶滩水电站、龙滩水电站和长洲水利枢纽库区的灭鼠率分别为83．89％、83．40％、92．82％、86．65％和89．35％。结论溴敌隆和杀鼠迷在水电站库区的灭鼠效果良好，采取综合灭鼠措施能更有效地控制水电站库区的鼠害。

Killing effect of rodents in parts of large reservoirs region in Guangxi Zhuang Nationality autonomous region

Objective To study killing effects to rodents in large reservoir region, and provide scientific basis for rodent control. Methods 0.1% sodium diphacinone was given indoor, and 0.005% Bromadiolone outdoor in the Pingban reservoir region. 0.005% Bromadiolone baits were given in the outdoors of the Baise reservoir, Ertan reservoir and Changzhou reservoir region, while 0.0375% Racumin wheat baits was taken in the indoor and outdoor of Longtan reservoir region. Results The killing rate was 83.89% in the Pingban reservoir, 83.40% in the Baise reservoir, 92.82% in the Ertan reservoir, 86.65% in the Longtan reservoir and 89.35% in the Changzhou reservoir region. Conclusion Bromadiolone and Raeumin had good killing effect on rodents in reservoir region, and the integrated control measure was taken to reduce effectively the rodent density.
