Aedes albopictus is a major nuisance pest and also a public health concern because of the role it plays in the transmission of arboviruses. There is a continuing demand for effective surveillance tools for this species. The first generation of Biogents Sentinel (BGS1) traps have proven to be an effective tool for surveillance of Ae. albopictus throughout its range, however, some defects in construction led to the eventual development of the next generation. We compared the performance of the new generation prototype trap (BGS2P) to the original. Studies were conducted in suburban and urban areas in Florida, Louisiana, New Jersey, and Virginia, USA in the summer of 2014 (July-October). BGS1 traps collected significantly more Ae. albopictus when compared to the BGS2P with or without CO2 in all locations (P<0.05). When a white cloth was wrapped around the BGS2P traps, efficiency did not change in Louisiana, New Jersey, and Virginia; however, numbers of adult Ae. albopictus collected from the BGS2P and the BGS1 were significantly different based on lure type (P< 0.0001). Results from Florida showed that BGS1with the BG lure and CO2 collected significantly higher adult numbers compared to BGS2P with a three component cartridge lure and CO2 (P< 0.0001). Overall, our results indicate that despite improvements in construction and durability of the BGS2P, this newer trap type did not increase the capture rates of Ae. albopictus in North America. Biogents modified BGS2P based on the data collected from the current study and updated as Biogents Sentinel 2 is now commercially available and its efficacy in comparison to the original will require further study.
白纹伊蚊是一种主要的骚扰性害虫，因其在虫媒病毒传播中所起的作用，也是一个公共卫生问题。对该物种有效的监测工具一直有需求。第一代Biogents Sentinel（BGS1）诱蚊器已被证明是监测白纹伊蚊的有效工具，然而，结构上的一些缺陷导致了下一代诱蚊器的最终研发。我们将新一代原型诱蚊器（BGS2P）与原始诱蚊器的性能进行了比较。2014年夏季（7月至10月）在美国佛罗里达州、路易斯安那州、新泽西州和弗吉尼亚州的郊区和市区开展了研究。在所有地点，无论有无二氧化碳，BGS1诱蚊器捕获的白纹伊蚊都显著多于BGS2P诱蚊器（P<0.05）。当在BGS2P诱蚊器周围包裹一块白布时，路易斯安那州、新泽西州和弗吉尼亚州的捕获效率没有变化；然而，基于诱捕剂类型，从BGS2P和BGS1诱捕到的成年白纹伊蚊数量有显著差异（P<0.0001）。佛罗里达州的结果表明，与配备三元组诱捕剂和二氧化碳的BGS2P相比，配备BG诱捕剂和二氧化碳的BGS1捕获的成年蚊虫数量显著更高（P<0.0001）。总体而言，我们的结果表明，尽管BGS2P在结构和耐用性方面有所改进，但这种新型诱蚊器并没有提高在北美白纹伊蚊的捕获率。Biogents根据当前研究收集的数据对BGS2P进行了改进，并更新为Biogents Sentinel 2，目前该产品已上市销售，其与原始产品相比的功效还需要进一步研究。
