Efficient detection of multiple species of adult mosquitoes in various habitats using effective traps is a crucial 1st step in any disease prevention program. Novel trap types that target tropical vectors of human diseases require field testing in the habitat of the vector-disease system in question. This paper analyzes a series of mosquito trapping studies conducted at Mapacocha, San Juan Bautista District, Loreto, Peru, during August-September 2013 and April-May 2014. Six trap configurations were evaluated in forest and rural locations. Adult mosquito counts were analyzed using full Bayesian inference of multilevel generalized linear models and posterior probability point estimates of the difference of means of the combined trap catch by trap type comparisons of all species. Light traps (Centers for Disease Control and Prevention [CDC] incandescent, white light-emitting diode [LED], and ultraviolet LED) caught greater numbers of mosquitoes compared with traps baited with yeast-generated CO and Biogents Sentinel traps (battery powered traps without light and passive box traps). However, diversity measures (species richness, evenness, and similarity) were consistently nearly equal among trap types. Arbovirus vectors were more common in forest locations, while malaria vectors were more common near human habitations. Location had a significant effect on trap effectiveness and mosquito diversity, with traps from forest locations having greater numbers and greater species richness, compared with traps set near human habitations. The results of this study will inform mosquito surveillance trap choices in remote regions of central South America, including regions with emerging tropical diseases, such and dengue and Zika virus.
使用有效的诱捕器在各种栖息地高效检测多种成年蚊子，是任何疾病预防计划的关键第一步。针对人类疾病热带传播媒介的新型诱捕器类型，需要在相关媒介 - 疾病系统的栖息地进行实地测试。本文分析了2013年8月至9月以及2014年4月至5月期间在秘鲁洛雷托圣胡安包蒂斯塔区马帕科查进行的一系列蚊子诱捕研究。在森林和农村地区评估了六种诱捕器配置。使用多水平广义线性模型的全贝叶斯推断以及通过所有物种的诱捕器类型比较对组合诱捕捕获量均值差异的后验概率点估计，对成年蚊子数量进行了分析。与用酵母产生的一氧化碳诱饵诱捕器和Biogents Sentinel诱捕器（无灯光的电池供电诱捕器和被动箱式诱捕器）相比，灯光诱捕器（疾病控制和预防中心[CDC]白炽灯、白色发光二极管[LED]和紫外线LED）捕获的蚊子数量更多。然而，诱捕器类型之间的多样性指标（物种丰富度、均匀度和相似度）始终几乎相等。虫媒病毒传播媒介在森林地区更为常见，而疟疾病媒在人类居住附近更为常见。地点对诱捕器效能和蚊子多样性有显著影响，与在人类居住附近设置的诱捕器相比，森林地区的诱捕器捕获的蚊子数量更多且物种丰富度更高。这项研究的结果将为南美洲中部偏远地区的蚊子监测诱捕器选择提供参考，包括登革热和寨卡病毒等新兴热带疾病流行地区。
