摘要

在佛罗里达州圣约翰县，黑盐沼蚊（Aedes taeniorhynchus）是一种主要的滋扰性蚊子。由于其典型的大规模爆发，以及与爆发相关的杀虫剂施用量的增加，当地的黑盐滨伊蚊种群产生杀虫剂抗药性的风险增加。这项研究的目的是确定太田姬蜂对氯菊酯和毒死蜱这两种技术级材料的基线敏感性。在 2023 年秋季爆发的两次疫情中，美国疾病控制和预防中心使用技术级材料进行了瓶生物测定。结果表明，对所测试的材料有基本的敏感性，但最值得注意的是，观察到了抗性击倒（kdr）的表型表达。结果突出表明，有必要继续监测和调查这种佛罗里达常见物种的抗性状况和抗性水平。

BASELINE SUSCEPTABILITY AND FIRST OBSERVATION OF KNOCKDOWN RESISTANCE IN AEDES TAENIORHYNCHUS POPULATION OF ST. JOHNS COUNTY, FLORIDA.

The black saltmarsh mosquito, Aedes taeniorhynchus, is a prominent nuisance mosquito within St. Johns County, Florida. Due to their characteristically large outbreaks, and the elevated amount of insecticide application correlated with the outbreaks, local populations of Ae. taeniorhynchus are at an increased risk of developing insecticide resistance. This study was established to form a baseline susceptibility of Ae. taeniorhynchus against two technical grade materials, permethrin, and chlorpyrifos. Centers for Disease Control and Prevention bottle bioassays were conducted with technical-grade materials during two outbreaks in the fall of 2023. Results indicated a baseline susceptibility against the materials tested, but most notably, the phenotypic expression of knockdown resistance (kdr) was observed. Results highlight the need for continued monitoring and investigation into the resistance status and resistance level of this common Florida species.
