Abstract:

Objective The purpose of this paper was to evaluate the efficacy of 0.004% fipronil bait against Reticulitermes in the laboratory and the sites where Reticulitermes occurred. Methods Efficacy test of fipronil bait against Reticulitermes chinensis was conducted in the laboratory and efficacy test against R. chinensis and R. flaviceps of was conducted in the buildings where Reticulitermes occurred. Results In the laboratory, the death of R. flaviceps occurred massively after feeding with bait in three days. The average mortality rate reached to 78.00%. All of the workers and soldiers were dead in 8 d. The average feeding rate of baits was 5.15%. For the application studies, fipronil bait was used in 15 office buildings and residences for R. chinensis and R. flaviceps from 2009 to 2015. Reticulitermes were wiped out by a single application for 13 sites, and twice, three times for the other 2 sites, respectively. Conclusion Reticulitermes chinensis and R. flaviceps could be effectively controlled by 0.004% fipronil bait in the sites where they occur.

摘要：

目的 观察0.004%氟虫腈白蚁饵剂实验室及室内现场对散白蚁的防治效果。方法 在实验室开展氟虫腈白蚁饵剂对黑胸散白蚁的药效实验,在室内现场测试氟虫腈白蚁饵剂对黑胸散白蚁和黄胸散白蚁的防治效果。结果 黑胸散白蚁取食饵剂3 d后开始大量死亡,平均死亡率达78.00%,8 d后工蚁和兵蚁全部死亡,氟虫腈白蚁饵剂平均被食率为5.15%。从2009-2015年使用氟虫腈白蚁饵剂防治15处办公楼和居民楼内的黑胸散白蚁和黄胸散白蚁,其中13处进行1次防治,其他2处分别进行2次和3次防治处理。结论 0.004%氟虫腈白蚁饵剂可有效诱杀黑胸散白蚁和黄胸散白蚁。
