Bistrifluron, a benzoylphenylurea compound, was evaluated for efficacy against Nasutitermes exitiosus (Hill), a mound-building species in southern Australia. Bistrifluron bait (trade name Xterm) was delivered as containerized pellets inserted into plastic feeding stations implanted in the sides of mounds-60 g for bistrifluron bait-treated mounds and 120 g of blank bait for untreated mounds. Termites actively tunneled in the gaps between pellets and removed bait from the canisters. All five treated mounds were eventually eliminated, and all five untreated mounds remained active at the end of the trial. Four of the five treated mounds were considered dead and excavated after 26 wk, but there were earlier signs of mound distress-reduced repair of experimental casement damage and reduced activity in bait canisters by 22 wk and reduced internal mound temperature after 11 wk. One treated mound showed activity in the bait station right through until almost the end of the trial (47 wk), but excavation at 49 wk showed no further activity in the mound. The five untreated colonies removed on average 97% of blank bait offered, while the five treated colonies removed on average 39.1% of bait offered. There was a wide variation in temperature profiles of mounds (up to 15°C for both minimum and maximum internal temperatures), from the beginning of the trial and even before the effects of baiting were evident.
双三氟虫脲是一种苯甲酰基苯基脲化合物，我们对其针对澳大利亚南部筑丘白蚁品种——毁灭鼻白蚁（希尔）的防治效果进行了评估。双三氟虫脲诱饵（商品名Xterm）以集装箱颗粒形式投放，插入埋在蚁丘侧面的塑料喂食站中，用于双三氟虫脲诱饵处理蚁丘的为60克，未处理蚁丘的空白诱饵为120克。白蚁在颗粒之间的缝隙中积极挖掘隧道，并从罐中取出诱饵。所有五个处理过的蚁丘最终都被消灭，在试验结束时，所有五个未处理的蚁丘仍然活跃。五个处理过的蚁丘中有四个在26周后被认为死亡并进行了挖掘，但在22周时就有早期迹象表明蚁丘出现问题——实验窗扉损坏修复减少、诱饵罐中的活动减少，11周后蚁丘内部温度降低。一个处理过的蚁丘在诱饵站一直有活动，直到试验几乎结束（47周），但在49周挖掘时发现蚁丘中没有进一步活动。五个未处理的蚁群平均消耗了提供的97%的空白诱饵，而五个处理过的蚁群平均消耗了提供的39.1%的诱饵。从试验开始甚至在诱饵效果明显之前，蚁丘的温度曲线就有很大差异（内部最低和最高温度高达15°C）。
