摘要
[ 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% （ out break） 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.
