Abstract:

Objective Monitoring?dusting technology is a recently developed technology for controlling termites. This technology is more environmentally friendly compared to traditional termiticide liquid barrier and has great potential for termite management. Our study is to investigate the effectiveness of this technology for controlling termites in the field. Methods The effectiveness to eliminate termite colony and to decrease numbers of termites was evaluated with the termite monitor?controlling device and 0.5% fipronil dust in the field. Results Among the 28 Coptotermes colonies and 50 Reticulitermes colonies tested, 17 Coptotermes colonies and 30 Reticulitermes colonies were completely eliminated. The individual numbers of 11 Coptotermes colonies and 20 Reticulitermes colonies have been reduced significantly. To eliminate one Coptotermes or one Reticulitermes colony, 5-10 grams or 3-5 grams of 0.5% fipronil dust were consumed respectively. In field tests, 27 005 monitor?controlling devices were installed in the area of 2 510 879 m². After applying the 0.5% fipronil dust to treat the termites in 2121 of 2333 monitor-controlling devices that detected the termites, no termites were found in 1919 monitor?controlling devices after six months. Conclusion Monitoring?dusting technology is an effective approach for controlling termites.
