Abstract

Thiamethoxam and fipronil were examined for their termiticidal properties against the Formosan subterranean termite, Coptotermes formosanus Shiraki, and the eastern subterranean termite, Reticulitermes flavipes (Kollar). Concentrations > or =8 ppm thiamethoxam and > or =1 ppm fipronil provided an effective barrier against C. formosanus and R. flavipes. Sand was penetrated to some degree at all concentrations of thiamethoxam (0-800 ppm for C. formosanus and 0-1000 ppm for R. flavipes) and fipronil (0-64 ppm for both C. formosanus and R. flavipes) tested, indicating that both termiticides are nonrepellent. Thiamethoxam was found to be more toxic against C. formosanus than R. flavipes whereas fipronil showed similar toxicity for both species. Higher mortality prevented termites from penetrating the entire 5-cm segment of treated sand.

摘要

对噻虫嗪和氟虫腈针对台湾乳白蚁（Coptotermes formosanus Shiraki）和东方地下白蚁（Reticulitermes flavipes (Kollar)）的杀白蚁特性进行了研究。浓度≥8 ppm的噻虫嗪和≥1 ppm的氟虫腈对台湾乳白蚁和黄胸散白蚁形成了有效的屏障。在测试的所有噻虫嗪浓度（台湾乳白蚁为0 - 800 ppm，黄胸散白蚁为0 - 1000 ppm）和氟虫腈浓度（台湾乳白蚁和黄胸散白蚁均为0 - 64 ppm）下，沙子都有一定程度的渗透，这表明这两种杀白蚁剂都无驱避性。发现噻虫嗪对台湾乳白蚁的毒性比对黄胸散白蚁更强，而氟虫腈对这两种白蚁显示出相似的毒性。较高的死亡率使白蚁无法穿透整个5厘米长的处理过的沙子段。
