Abstract: Objective To find the baits that the Yangtze vole (Microtus fortis) likes to eat to confect poisonous baits, and strengthen control capability forM.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.
