The western tree hole mosquito, Aedes sierrensis (Ludlow), is a common nuisance mosquito and vector of Dirofilaria immitis (Leidy), the etiologic agent of dog heartworm, in western North America. Here, we compare weekly mosquito collections made with Mosquito Magnet (MM) traps, Biogents Sentinel (BGS) traps, and Biogents Bowl (BGS Bowl) traps set in Salt Lake City, UT, from the start of June to mid-August 2017. We found the number of mosquitoes decreased with rainfall and temperature independently of trap type. The highest number of mosquitoes were caught by BGS traps baited with carbon dioxide (CO2) and BG lure, which collected 62% (n = 422) of all mosquitoes, followed by the MM at 31% (n = 213), and both the BGS and BG Bowl with BG lure had 3.5% (n = 24) each. Aedes sierrensis females were caught weekly at similar densities (mean ± SD) in BGS with CO2 and lure (1.17 ± 2.93) and the MM (1.17 ± 2.66) traps during the study period. Given that BGS with CO2 and lure traps have several operational advantages over MM traps, including a quicker setup, smaller size, and lower cost, we consider BGS with CO2 and lure traps as the best suited surveillance tool to detect and remove Ae. sierrensis in the western United States and similar settings throughout North America.

西部树洞蚊子监视的陷阱比较（双翅目：葫芦科）。

西部树洞蚊（Aedes sierrensis）（Ludlow）是北美西部犬心丝虫的病原体，Diorfilaria炎（Leidy）的常见害虫和媒介。在这里，我们比较了从2017年6月初至8月中旬在犹他州盐湖城设置的蚊帐（MM），诱饵哨兵（BGS）和诱饵碗（BGS Bowl）捕集的蚊子每周收集量。我们发现蚊子的数量随降雨和温度的下降而减少，与诱捕器的类型无关。被二氧化碳（CO2）和BG诱饵诱捕的BGS诱捕器捕获的蚊子数量最多，该诱集器收集了所有蚊子的62％（n = 422），其次是MM，占31％（n = 213）。具有BG诱饵的BGS和BG碗各占3.5％（n = 24）。在研究期间，每周以相似的密度（平均值±标准差）将白纹伊蚊（Aedes sierrensis）捕获在BGS中，并带有CO2和诱饵（1.17±2.93）和MM（1.17±2.66）陷阱。鉴于带有CO2和诱饵捕集阱的BGS具有比MM捕集阱更多的操作优势，包括安装速度更快，尺寸更小，成本更低，因此我们认为带有CO2和诱饵捕集阱的BGS是最适合检测和去除Ae的监视工具。美国西部的sierrensis和整个北美的类似环境。
