The relative efficacy of gravid and under-house CO2 traps for monitoring mosquito species of public health importance within the Houston metroplex area was assessed. Gravid and under-house traps were colocated at 10 sites and monitored weekly between 1 March to 31 May 2007. The most numerous species caught was Culex pipiens quinquefasciatus Say. Other species of public health importance caught in gravid and under-house traps included Culex restuans Theobald, Aedes aegypti (L.), and Aedes albopictus Skuse. Adjusting for the week of collection, gravid traps caught significantly more mosquitoes (mean 23.1 per trap) in the study area than under-house traps (mean 3.6 per trap). However, under-house traps caught a greater variety of mosquito species (13) than gravid traps (11). Gravid and under-house traps only caught nine of 15 of the same mosquito species during the study period. In this study area, gravid traps should be used as the primary method of surveillance for mosquito-borne diseases of public health importance during the early part of the season, because of greater catch numbers of mosquitoes that pose a public health risk.
评估了在休斯顿都会区,用于监测具有公共卫生重要性的蚊子种类的孕蚊诱捕器和室内诱捕器的相对功效。在 2007 年 3 月 1 日至 5 月 31 日期间,在 10 个地点将孕蚊诱捕器和室内诱捕器放在一起,并每周进行监测。捕获的数量最多的物种是库蚊埃及亚种。在孕蚊诱捕器和室内诱捕器中捕获的其他具有公共卫生重要性的物种包括库蚊未定种、埃及伊蚊和白纹伊蚊。调整收集周数后,研究区域内的孕蚊诱捕器捕获的蚊子数量(平均每诱捕器 23.1 只)明显多于室内诱捕器(平均每诱捕器 3.6 只)。然而,室内诱捕器捕获的蚊子种类(13 种)多于孕蚊诱捕器(11 种)。在研究期间,孕蚊诱捕器和室内诱捕器仅捕获了 15 种相同蚊子种类中的 9 种。在该研究区域,由于具有更大公共卫生风险的蚊子捕获数量更多,因此在季节早期,应该使用孕蚊诱捕器作为监测具有公共卫生重要性的蚊媒疾病的主要方法。
