New intervention methods and product formulations are needed to better control pyrethroid-resistant populations and mitigate the risk of mosquito-borne disease. ReMoa Tri is a novel adulticidal space spray that utilizes a different mode of action than the commonly used adulticides: pyrethroids and organophosphates. As a triple-action space spray, ReMoa Tri combines three components: Fenpropathrin, a mixed-type I/II pyrethroid; abamectin, a macrocyclic lactone; and C8910, a patented fatty acid chain. Prior studies performed by Collier Mosquito Control District showed that ReMoa Tri is effective at controlling type I pyrethroid-resistant mosquitoes. To further validate these results and the performance of ReMoa Tri, we conducted a semi-field evaluation using ground and aerial ULV (ultra-low volume) applications with field-caught deltamethrin-resistant and a susceptible laboratory strain. Ground evaluations tested ReMoa Tri and a type II pyrethroid-based product, DeltaGard. While ReMoa Tri was equally effective against Collier's deltamethrin-resistant and the susceptible laboratory strain, DeltaGard was effective against both strains, with reduced efficacy at farther distances. Similarly, aerial evaluations also showed that ReMoa Tri was equally effective against Collier's deltamethrin-resistant strain and susceptible laboratory strain. This study further confirms ReMoa Tri's potential as an effective alternative to pyrethroid-based adulticides, both in ground and aerial applications, for managing pyrethroid-resistant .
需要新的干预方法和产品配方来更好地控制对拟除虫菊酯产生抗性的种群，并降低蚊媒疾病的风险。ReMoa Tri是一种新型的成人杀虫剂空间喷雾，其作用方式与常用的成人杀虫剂（拟除虫菊酯和有机磷酸盐）不同。作为一种三效空间喷雾，ReMoa Tri结合了三种成分：甲氰菊酯，一种I/II混合型拟除虫菊酯；阿维菌素，一种大环内酯；以及C8910，一种专利脂肪酸链。科利尔蚊虫控制区之前进行的研究表明，ReMoa Tri在控制I型拟除虫菊酯抗性蚊子方面有效。为了进一步验证这些结果以及ReMoa Tri的性能，我们使用地面和空中超低容量（ULV）应用对野外捕获的抗溴氰菊酯和敏感实验室菌株进行了半田间评估。地面评估测试了ReMoa Tri和一种基于II型拟除虫菊酯的产品DeltaGard。虽然ReMoa Tri对科利尔的抗溴氰菊酯菌株和敏感实验室菌株同样有效，但DeltaGard对两种菌株都有效，只是在更远的距离效果有所降低。同样，空中评估也表明，ReMoa Tri对科利尔的抗溴氰菊酯菌株和敏感实验室菌株同样有效。这项研究进一步证实了ReMoa Tri作为基于拟除虫菊酯的成人杀虫剂的有效替代品在地面和空中应用中管理拟除虫菊酯抗性方面的潜力。
