摘　　要：寻找对赤腹松鼠适口性良好的饵料配制毒饵,以防治赤腹松鼠对人工经济林造成的严重危害,以当地常见的苹果、胡萝卜和玉米为饵料,在实验室内做了适口性比较。结果表明:以苹果做对照,在单饵料选择中,胡萝卜和玉米的摄食系数分别为0.88和0.49;多饵料选择中,胡萝卜和玉米的摄食系数分别为0.36和0.30。苹果的适口性最佳,其次是胡萝卜和玉米。另外还在室内对不同浓度的溴敌隆和不育剂毒饵的适口性和灭鼠效果进行了试验,结果显示:各种浓度的溴敌隆和不育剂毒饵的适口性均达到"好"的标准,各种浓度溴敌隆毒饵的适口性均好于不育剂毒饵,防效最好的是浓度为0.01%的溴敌隆和1.00%的不育剂毒饵,灭鼠率达到了100%。毒饵首次投放后,溴敌隆毒饵的灭杀效果优于不育剂毒饵,但致死时间较长。综合考虑适口性、灭鼠率和致死时间3个因素,以含水量较好的苹果为饵料配制成有效成分为0.01%的溴敌隆或1.00%的不育剂毒饵防治赤腹松鼠为宜。In order to identify palatable base baits to confect poisonous baits,to control the damage of the red bellied squirrel in economic plantation,experiments were conducted on the palatability of three common baits（ apples,carrots and corns） for the red bellied squirrels in laboratory. The results showed that in single-choice tests,the palatability index of apples to carrots and corns were 0. 88 and 0. 49,respectively.In multi-choice tests,the palatability index of apples to carrots and corns were 0. 36 and 0. 30,respectively. The palatability of apples was the best,followed by carrots and corns. Tests were also made on the palatability and deratization effect of bromadiolone and chemosterilant baits in different concentration. The results showed that palatability of all poisonous baits were good,and the palatability of bromadiolone baits was better than that of chemosterilant baits. 0. 01% bromadiolone baits and 1. 00% chemosterilant baits would cause 100% mortality. The deratization effect of bromadiolone baits was better than that of chemosterilant baits after the first feeding,but the lethal time was longer. Taking palatability,killing rates and le-thal time into account,the use of 0. 01% bromadiolone apple baits and 1. 00% chemosterilant apple baits were recommended to control the red bellied squirrels.
