在过去的30年里，在全球范围内已经记录了一些有限的外来蚂蚁控制成功，控制计划仍然具有挑战性。此外，有毒物质的潜在非目标影响尚未得到充分研究。我们评估了含有活性化合物氟虫腈的多种产品在试图控制日本东京的两个入侵阿根廷蚂蚁Linepithema humile（Mayr）种群中的有效性和非靶效应。进行了三种处理：对照、低剂量处理（每次处理0.1克/公顷）和高剂量处理（0.2克/公顷）。治疗每月一次，持续11个月。L.在处理区，humile迅速下降高达99.8%，但在对照区仍保持极高的密度。这些处理几乎没有负面的非目标效应，在L.卑微的压抑因此，氟虫腈是一种有效的防治L.温和，并且可以在对非目标生物体的毒性作用最小的情况下使用。低剂量处理的费用约为575美元/公顷，高剂量处理的费用约为1，250美元/公顷。我们的研究支持创建更雄心勃勃的入侵蚂蚁管理项目。
In the last 30 years some limited successes in alien ant control have been documented globally, and control programs remain challenging. Moreover, the potential non-target impacts of toxicants have not been well studied. We assessed the efficacy and non-target effects of multiple products containing the active compound fipronil in the attempted control of two populations of the invasive Argentine ant Linepithema humile (Mayr) in Tokyo, Japan. Three treatments were conducted: control, low-dose treatment (0.1 g/ha per treatment), and high-dose treatment (0.2 g/ha). Treatments were applied once per month for 11 months. The abundance of L. humile declined rapidly by up to 99.8 % in treated areas, but remained at extremely high densities in the control area. The treatments had few negative non-target effects, with the abundances of native ant species and other ground-dwelling invertebrates except for cockroaches being greater in the treated areas after L. humile suppression. Thus, fipronil is an effective compound for controlling L. humile and can be used with minimal toxic effects on non-target organisms. The treatments cost approximately US$ 575/ha for the low-dose treatment and US$ 1250/ha for the high-dose treatment. Our research supports the creation of more ambitious invasive ant management projects.
