草原鼢鼠实验室饵料筛选试验

目的 寻找对草原鼢鼠适口性好的饵料以配制毒饵,在草原鼢鼠交尾的高峰期进行防治.方法 以当地常见的饵料胡萝卜、马铃薯、红薯、玉米、花生米、莜麦分别做适口性对比.结果 胡萝卜对其他饵料摄食系数单独对比为0.65、0.36、0.39、0.25和0.44,群饲对比为0.50、0.90、0.01、0.21和0.13,以胡萝卜适口性最佳,马铃薯、红薯的适口性也较好,玉米、花生米、莜麦适口性差,群饲摄食系数均＜0.30.结论 防治草原鼢鼠以含水量较高的胡萝卜、马铃薯、红薯作为饵料配制毒饵为佳.

Selective tests on Myospalax aspalax baits in laboratory

Objective To identify palatable baits for Myospalax aspalax for the basis of poisonous baits during the pairing season.Methods M.aspalax were fed with different baits such as carrots,potatoes,sweet potatoes,corns,peanuts and naked oats in laboratory for comparison of palatability.Results The palatability index of carrots to potatoes,sweet potatoes,corns, peanuts and naked oats were 0.65,0.36,0.39,0.25 and 0.44 when feeding alone,and 0.50,0.90,0.01,0.21 and 0.13 when group feeding,respectively.Carrots were t...
