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.
