The development of baits for subterranean termite control over the past 25 yr has provided cost-effective alternatives to liquid termiticide treatments. Current bait products use one of the few available benzoylurea chitin synthesis inhibitors (CSIs) labeled for subterranean termites. These insecticides are used because of their nonrepellency, their slow-acting mode of action, and their dose-independent lethal time. Although many studies have provided ample evidence of the efficacy of CSI baits for subterranean termite colony elimination, most have focused on hexaflumuron and noviflumuron. However, bait products using alternative CSIs have not received the same level of scrutiny, limiting the amount of evidence proving their efficacy. One such compound is novaluron, the active ingredient currently used in the Trelona ATBS—Advance Termite Baiting System bait product. The current study independently tested the efficacy of this commercially available bait formulation against whole colonies of Coptotermes gestroi (Wamann) (~63,910 workers) in the laboratory, using an extended experimental setup to simulate a 15-m foraging distance from the central part of the nest to the bait, while having access to alternative food sources. Treated colonies progressively ceased to feed on wood items within 45 d after being provided access to the novaluron bait formulation, with a subsequent progressive collapse of the population, leading to colony elimination by 91 d. This study therefore confirms the efficacy of novaluron baits against subterranean termites, and currently remains one of the few CSIs that can be applied for the successful control of Coptotermes infestations.

地下白蚁 (Coptotermes gestroi (Blattodea: Rhinotermitidae)) 通过在实验室中暴露于 Novaluron CSI 诱饵配方来消除菌落

在过去的 25 年中，用于控制地下白蚁的诱饵的开发为液体杀白蚁剂处理提供了具有成本效益的替代方案。目前的诱饵产品使用为地下白蚁标记的少数可用的苯甲酰脲几丁质合成抑制剂 (CSI) 之一。使用这些杀虫剂是因为它们的非驱虫性、作用缓慢的作用方式以及与剂量无关的致死时间。尽管许多研究提供了充分的证据证明 CSI 诱饵对消灭地下白蚁群落的功效，但大多数研究都集中在六氟嘧啶和新氟嘧啶上。然而，使用替代 CSI 的诱饵产品并未受到同等程度的审查，从而限制了证明其有效性的证据数量。一种这样的化合物是诺瓦隆，Trelona ATBS—Advance 白蚁诱饵系统诱饵产品中目前使用的活性成分。目前的研究在实验室中独立测试了这种市售诱饵配方对Coptotermes gestroi (Wamann) 整个菌落（约63,910 名工人）的功效，使用扩展的实验装置来模拟距白蚁中央部分15 米的觅食距离。窝在诱饵上，同时可以获得替代食物来源。处理过的菌落在获得 novaluron 诱饵配方后的 45 天内逐渐停止以木制品为食，随后种群逐渐崩溃，导致菌落在 91 天时消失。因此，这项研究证实了 novaluron 诱饵对地下白蚁的功效，
