Despite the importance of Aedes, Haemagogus and Sabethes in the transmission of yellow fever virus (YFV) and the public health impacts of recent YFV epidemics in the Americas, relatively little has been reported on the biology and ecology of these vectors. Many Aedes, Haemagogus and Sabethes spp. in the American tropics inhabit and develop in the forest canopy and are difficult to sample with conventional entomological surveillance methods. We tested the utility of two previously developed phytotelmata-style oviposition traps (bamboo Guadua angustifolia) and (monkey-pot Lecythis minor), for collecting immature forms of these mosquitoes in a forest near the community of Aruza Abajo, Darién Province, Panama. Our results showed distribution of mosquito species emerging from the two types of traps was found to be significantly different (X = 210.23; df = 14; P < 0.001), with significantly greater numbers of Sabethes (Peytonulus) aurescens (Lutz) and Sabethes (Peytonulus) undosus (Coquillett) emerging from the bamboo traps. More females of Sabethes (Sabethes) cyaneus (Fabricius) were captured in the monkey-pot traps, although the difference was not significant. No differences were observed in the average time to emergence for the two traps. These results suggest that various phytotelmata-style traps, including monkey-pot and bamboo, could be used to improve entomological surveillance of YFV vectors in the American tropic.
尽管伊蚊属、趋血蚊属和萨氏蚊属在黄热病毒（YFV）传播中具有重要性，且近期美洲YFV疫情对公共卫生产生了影响，但关于这些病媒的生物学和生态学的报道相对较少。美洲热带地区的许多伊蚊属、趋血蚊属和萨氏蚊属物种栖息并在树冠层中发育，使用传统昆虫学监测方法难以对其进行采样。我们测试了两种先前开发的附生植物型产卵诱捕器（ Guadua angustifolia竹和Lecythis minor猴罐）在巴拿马达连省阿鲁萨阿巴霍社区附近森林中收集这些蚊子幼虫的效用。我们的结果表明，从两种诱捕器中羽化出的蚊虫种类分布存在显著差异（X = 210.23；自由度 = 14；P < 0.001），从竹制诱捕器中羽化出的奥氏萨氏蚊（佩顿萨氏蚊亚属）（Lutz）和波动萨氏蚊（佩顿萨氏蚊亚属）（Coquillett）数量显著更多。虽然差异不显著，但在猴罐诱捕器中捕获的蓝萨氏蚊（萨氏蚊亚属）（Fabricius）雌性更多。两种诱捕器的平均羽化时间没有差异。这些结果表明，包括猴罐和竹子在内的各种附生植物型诱捕器可用于改进美洲热带地区YFV病媒的昆虫学监测。
