Treatments consisted of two replicates applied to either four or eight PVC bait stations per ha in treatment blocks, and one control applied to eight PVC bait stations containing non-toxic baits (rice baits). Toxic baits were delivered in early March, 2014. The control effect after delivering toxic baits were evaluated by investigating new damage number, feeding rate of non-toxic baits and individual numbers observed in April to July, September and December in both treatment and control plots. The results showed that, in April, new bark-stripping damage in the treatment plots decreased by 90.00%, 85.71%, 93.75% and 77.78%, respectively, and the difference between treatment and control plots was significant; Feeding rates of non-toxic baits in the treatment plots decreased by 83.33%, 91.30%, 97.18% and 94.83%, respectively, and these values also significantly differed with the control plot. Additionally, in April, the number of individuals observed in the treatment plots decreased by 83.33%. No case of non-target species and secondary poisoning was observed. The results indicated that bait stations with 0.005% bromadiolone rice baits were effective for controlling red-bellied squirrel caused bark-stripping damage. Thus, for Hongya artificial forest, we recommended an application rate of four bait stations per ha. Delivering toxic bait in March once a year can control bark-stripping damage caused by red-bellied squirrels. 2015,34(6): 916-920 收稿日期：2015-05-12 DOI：10.11984/j.issn.1000-7083.20150174 分类号：Q959.837 基金项目："十二五"农村领域国家科技计划课题: 林区鼠害防控技术研发与应用(No.2012BAD19B00) 作者简介：李盼峰(1990—),男,动物学专业硕士研究生,E-mail:leepanfeng@163.com *通讯作者：郭聪,教授,E-mail:gc6252@sina.com 参考文献： 蔡红霞, 冉江洪, 张家平, 等. 2001. 赤腹松鼠危害季节性变化与食性的初步探讨[J]. 四川林业科技, 22(3): 21-24. 董岚, 纪岷, 徐玮, 等. 2009.
