采用三种室内试验方法，研究了苯甲酰苯基脲类化合物双三氟隆对台湾乳白蚁工蚁的防治效果。在无选择进食测试中，双三氟隆处理的工蚁的死亡率显着高于暴露于相同浓度氟铃脲的白蚁（例如，在500 ppm下6周，在5，000 ppm下4周，和在50，000 ppm下2周）和未处理的对照。双三氟隆比氟铃脲表现出更高的剂量依赖性和更快的作用速度。双三氟隆和氟铃脲在5，000 ppm的双选择喂养试验中具有喂养威慑作用，尽管暴露于5，000 ppm双三氟隆或氟铃脲的工蚁死亡率与未处理的对照组没有显著差异。在异理毛抑制试验中，为了检查双三氟隆对白蚁异理毛行为的影响，当暴露于5，000 ppm双三氟隆时，白蚁在白蚁死亡前1周的运动受到影响。这些结果表明，双三氟隆在5，000 ppm时作为诱饵毒物是有效的;然而，双三氟隆在>或= 5，000 ppm时可能会引起一定的拒食性。
Bistrifluron, a benzoylphenylurea compound, was evaluated with regard to its efficacy against workers of Coptotermes formosanus Shiraki (Isoptera: Rhinotermitidae) by using three laboratory tests. In the no-choice feeding test, the mortality of bistrifluron-treated worker termites was significantly higher than that of termites exposed to the same concentrations of hexaflumuron (e.g., 6 wk at 500 ppm, 4 wk at 5,000 ppm, and 2 wk at 50,000 ppm) and untreated controls. Bistrifluron showed higher dose dependence and a faster speed of action than hexaflumuron. Both bistrifluron and hexaflumuron had feeding-deterrent effects at 5,000 ppm in the two-choice feeding test, although the mortality of worker termites exposed to bistrifluron or hexaflumuron at 5,000 ppm was not significantly different from untreated controls. In the allogrooming inhibition test, to examine effects of bistrifluron on allogrooming behavior of termites, termite movement was affected at 1 wk before termites died when exposed to 5,000 ppm bistrifluron. These results indicate bistrifluron is effective as a bait toxicant at 5,000 ppm; however, bistrifluron may cause some feeding repellency at > or = 5,000 ppm.
