Vector-borne diseases are a major burden to public health. Controlling mosquitoes is considered the most effective way to prevent vector-borne disease transmission. Mosquito surveillance is a core component of integrated vector management, as surveillance programs are often the cornerstone for the development of mosquito control operations. Two traps are the most commonly used for the surveillance of adult mosquitoes: Centers for Disease Control and Prevention miniature light trap (CDC light trap) and BG-Sentinel trap (BioGents, Regensburg, Germany). However, despite the importance of the BG-Sentinel trap in surveillance programs in the United States, especially in the Southern states, its effectiveness in consistently and reliably collecting mosquitoes in rural and natural areas is still unknown. We hypothesized that BG-Sentinel and CDC light traps would be more attractive to specific mosquito species present in rural and natural areas. Therefore, our objective was to compare the relative abundance, species richness, and community composition of mosquitoes collected in natural and rural areas by BG-Sentinel and CDC light traps.
Mosquitoes were collected from October 2020 to March 2021 using BG-Sentinel and CDC light traps baited with dry ice, totaling 105 trap-nights.
The BG-Sentinel traps collected 195,115 mosquitoes comprising 23 species from eight genera, and the CDC light traps collected 188,594 mosquitoes comprising 23 species from eight genera. The results from the permutational multivariate analysis of variance (PERMANOVA) and generalized estimating equation model for repeated measures indicate the BG-Sentinel and CDC light traps had similar sampling power.
Even though BG-Sentinel traps had a slightly better performance, the difference was not statistically significant indicating that both traps are suitable to be used in mosquito surveillance in rural and natural areas.
虫媒传染病是公共卫生的主要负担。控制蚊子被认为是预防虫媒传染病传播的最有效方法。蚊虫监测是综合媒介管理的核心组成部分，因为监测计划通常是制定蚊虫控制行动的基石。两种诱捕器是最常用于监测成蚊的：疾病控制与预防中心微型灯诱捕器（CDC 灯诱捕器）和 BG-Sentinel 诱捕器（德国雷根斯堡的 BioGents）。然而，尽管 BG-Sentinel 诱捕器在美国的监测计划中非常重要，尤其是在南部各州，但其在农村和自然区域持续可靠地收集蚊子的效果仍不清楚。我们假设 BG-Sentinel 和 CDC 灯诱捕器对农村和自然区域存在的特定蚊子种类更具吸引力。因此，我们的目标是比较 BG-Sentinel 和 CDC 灯诱捕器在自然和农村地区收集的蚊子的相对丰度、物种丰富度和群落组成。
从 2020 年 10 月至 2021 年 3 月，使用 BG-Sentinel 和 CDC 灯诱捕器（用干冰诱饵）共进行了 105 个诱捕夜的蚊虫采集。
BG-Sentinel 诱捕器共收集了 195115 只蚊子，包括 8 个属的 23 种；CDC 灯诱捕器共收集了 188594 只蚊子，包括 8 个属的 23 种。基于重复测量的可置换多元方差分析（PERMANOVA）和广义估计方程模型的结果表明，BG-Sentinel 和 CDC 灯诱捕器具有相似的采样能力。
尽管 BG-Sentinel 诱捕器的性能略好，但差异无统计学意义，这表明这两种诱捕器都适合在农村和自然区域进行蚊虫监测。
