摘　　要：目的寻找对东方田鼠适口性好的饵料以配制毒饵,在发现东方田鼠可能迁移入垸时进行预防性治理。方法以防治农田害鼠常用的饵料——稻谷为对照饵料,比较西瓜、西红柿、梨、苹果、马铃薯、南瓜等饵料的适口性;同时,又以西瓜、西红柿、苹果、梨作对照饵料,分别与其他瓜果饵料进行适口性比较。结果西瓜、西红柿、苹果、梨、马铃薯对东方田鼠的适口性优于稻谷,摄食系数分别为4.73、4.15、3.40、3.28、1.85,尤以前4种饵料的适口性最佳,摄食系数均在3.00以上;在以瓜果饵料为对照的试验中,也以西瓜、西红柿、苹果和梨的适口性最好,南瓜的适口性最差,摄食系数均在0.30以下。结论可用含水较高的西瓜、西红柿、梨、苹果、马铃薯作为饵料配制毒饵,防治东方田鼠,尤以前4种饵料为佳。Objective To find the baits that the Yangtze vole （Microtus fortis） likes to eat to confect poisonous baits, and strengthen control capability for M. fortis in the Dongting Lake region. Methods To compare the edibility of voles to watermelon, tomato, pear, apple, potato and pumpkin when rice acts as control, and to compare their edibility with other melon and fruit baits when watermelon, tomato, pear and apple act as control. Results The edibility coefficients of voles feeding watermelon, tomato, apple, pear, potato were 4.73, 4.15, 3.40, 3.28 and 1.85 respectively, which were superior to that of rice. Of which, the palatability of former 4 baits was the best, and its edibility coefficients of watermelon, tomato, pear, apple exceeded 3.00. In the test of melon and fruit baits as control, the palatability of watermelon, tomato, pear and apple was also the best, and that of pumpkin was the worst which edibility coefficient was less than 0.30. Conclusion The test indicated that the melon and fruit full with water could be used to make poisonous bait to control the voles,
