The hand-net is the standard method for capturing mosquitoes with sylvatic diurnal activity in disease outbreaks in Brazil. However, occupational risks and biases related to the collectors' abilities and attractiveness are important limitations. In this study, we compared hand-nets with automatic traps (CDC) associated to CO and BG-Lure in the Vassununga State Park, a Brazilian Savanna protection area. The collections carried out over 27 days on the ground and the forest canopy. A total of 1555 mosquitoes were obtained in 20 taxa. The diversity index ranged between 1.12 and 1.79 and the dominance index from 0.22 to 0.40. The dominant species on the ground was (46.0%), and in the canopy, (31.9%). was rare ( = 2). The hand-net resulted in the greatest diversity and abundance of species in both strata, followed by the traps associated with CO. A low degree of similarity was observed between the hand-net on the ground compared to the other capture methods. The use of BG-Lure alone resulted in a low number of specimens. In conclusion, the hand-net is still the method of choice for collecting arbovirus vectors in the diurnal period, especially yellow fever vectors.
在巴西疾病暴发期间，手网是捕捉具有野生日间活动习性蚊子的标准方法。然而，与采集者能力和吸引力相关的职业风险和偏差是重要的局限性。在本研究中，我们在巴西热带稀树草原保护区瓦苏农加国家公园，将手网与配备一氧化碳（CO）和BG引诱剂的自动诱捕器（疾控中心诱捕器）进行了比较。在地面和森林树冠层进行了为期27天的采集。共捕获了20个分类单元的1555只蚊子。多样性指数在1.12至1.79之间，优势度指数在0.22至0.40之间。地面上的优势物种是 （占46.0%），树冠层的优势物种是 （占31.9%）。 很罕见（ = 2）。手网在两个层次中捕获的物种多样性和数量最多，其次是配备CO的诱捕器。与其他捕获方法相比，地面上手网捕获的结果与其他方法的相似度较低。单独使用BG引诱剂捕获的标本数量较少。总之，手网仍然是日间采集虫媒病毒载体，尤其是黄热病毒载体的首选方法。
