Eastern subterranean termite, Reticulitermes flavipes (Kollar), workers were continuously exposed to one of five chitin synthesis inhibiting (CSI) active ingredients and the protist community from the hindgut quantified biweekly for 21 d. The CSIs tested included commercially available formulations of diflubenzuron, hexaflumuron, lufenuron, noviflumuron, and novaluron. Results showed termites exposed to CSIs had a significant decrease (>or=30%) in the estimated total protist population after 3 d, regardless of treatment. Protist species impacted were Dinenympha fimbriata, D. gracilis, Microjoenia fallax, Pyrsonympha vertens, and Trichonympha agilis and could be indicative of weakened digestive homeostasis, but further studies are needed. We also provide evidence that lufenuron is highly toxic and discuss some of the implications this might have on termite management practices.
将东部地下白蚁（Reticulitermes flavipes (Kollar)）的工蚁持续暴露于五种几丁质合成抑制（CSI）活性成分之一，并每两周对后肠中的原生生物群落进行定量，持续21天。所测试的CSI包括敌氟虫脲、氟铃脲、虱螨脲、氟虫脲和诺瓦隆的市售制剂。结果表明，无论采用何种处理方式，暴露于CSI的白蚁在3天后估计的原生生物总数均显著减少（≥30%）。受到影响的原生生物物种有流苏双鞭毛虫（Dinenympha fimbriata）、纤细双鞭毛虫（D. gracilis）、伪乔氏虫（Microjoenia fallax）、垂顶毛虫（Pyrsonympha vertens）和敏捷披发虫（Trichonympha agilis）；这可能表明消化内稳态受到削弱，但还需要进一步研究。我们还提供了虱螨脲具有高毒性的证据，并讨论了这可能对白蚁管理实践产生的一些影响。
