Members of the Culex pipiens complex are principal vectors for West Nile virus (WNV) in the USA. Previous studies have shown that gravid traps might be more effective than CO2-baited traps in sampling for Cx. pipiens. We compared the efficacy of gravid traps manufactured by 3 different companies: Bioquip, Clarke, and J. W. Hock. All gravid traps have a similar setup to hold the oviposition attractant but differ in the way they collect the mosquitoes. The gravid trap manufactured by J. W. Hock Company trapped significantly more Cx. pipiens than the other traps. Because CO2-baited American Biophysics Corporation (ABC) traps are most often used by mosquito abatement agencies, we compared the efficacy of the Hock gravid trap with a CO2-baited ABC trap. There was no significant difference in the number of Cx. pipiens trapped between the Hock gravid and CO2-baited ABC trap. Because gravid traps predominantly attract previously bloodfed females (thereby aiding in WNV surveillance) and are logistically easier and cheaper to set up, we argue that the Hock gravid trap might be ideal for sampling Cx. pipiens populations.
尖音库蚊复合组的成员是美国西尼罗河病毒（WNV）的主要传播媒介。先前的研究表明，在对尖音库蚊进行采样时，孕蚊诱捕器可能比二氧化碳诱饵诱捕器更有效。我们比较了由3家不同公司制造的孕蚊诱捕器的效果：Bioquip公司、Clarke公司和J. W. Hock公司。所有孕蚊诱捕器都有类似的装置来放置产卵引诱剂，但在收集蚊子的方式上有所不同。J. W. Hock公司制造的孕蚊诱捕器捕获的尖音库蚊明显多于其他诱捕器。由于蚊虫防治机构最常使用二氧化碳诱饵的美国生物物理公司（ABC）诱捕器，我们将Hock孕蚊诱捕器与二氧化碳诱饵的ABC诱捕器的效果进行了比较。Hock孕蚊诱捕器和二氧化碳诱饵的ABC诱捕器捕获的尖音库蚊数量没有显著差异。由于孕蚊诱捕器主要吸引先前吸食过血液的雌蚊（从而有助于西尼罗河病毒监测），并且在后勤方面设置起来更容易、成本更低，我们认为Hock孕蚊诱捕器可能是对尖音库蚊种群进行采样的理想选择。
