[Objective] The paper was to explore the deratization and anti fertility effect of triptolide on farmland rats in Sanya City. [Method] Autumn and spring control tests were carried out in Potianyang and Miaolinyang,respectively. [Result] The rat density in autumn control area decreased from 28. 57%( outbreak) to 2. 86%,3. 81% and 6. 80% at 11,41 and 70 d after triptolide treatment,respectively. The rat density in spring control area was lower at 19 and 47 d post treatment,and the correction deratization effect was 99. 48%-99. 88%. The testicular descent rate and pregnancy rate decreased significantly after treatment of triptolide. [Conclusion] Triptolide was safe in application,and is hence recommended for large scale extension in the farmland in Sanya City.

[Result] The rat density in autumn control The rat density in spring control area was lower at 19 and decreased from 28. 57% (outbreak) to 2. 86%, 3.81% and 6.80% at 11,41 and 70 days after triptolide treatment, respectively. 47 d post treatment, and the correction deratization effect was 99. 48% -99. 88%. The testicular descent rate and pregnancy rate decreased significantly after treatment of triptolide. [Conclusion] Triptolide was safe in application, and subsequently therefore recommended for large scale extension in the farmland in Sanya City.
