The control of arboviruses carried by Aedes aegypti (Linnaeus) and Aedes albopictus (Skuse) can be performed with tools that monitor and reduce the circulation of these vectors. Therefore, the efficiency of four types of traps in capturing A. aegypti and A. albopictus eggs and adults, with the biological product Vectobac WG, was evaluated in the field. For this, 20 traps were installed in two locations, which were in the South (Londrina, Paraná) and North (Manaus, Amazonas) Regions of Brazil, from March to April 2017 and January to February 2018, respectively. The UELtrap-E (standard trap) and UELtrap-EA traps captured A. aegypti and A. albopictus eggs: 1703/1866 eggs in Londrina, and 10268/2149 eggs in Manaus, respectively, and presented high ovitraps positivity index (OPI) values (averages: 100%/100% in Londrina, and 100%/96% in Manaus, respectively); and high egg density index (EDI) values (averages: 68/75 in Londrina, and 411/89 in Manaus, respectively), so they had statistically superior efficiency to that of the CRtrap-E and CRtrap-EA traps in both regions, that captured less eggs and adults: 96/69 eggs in Londrina, and 1091/510 eggs in Manaus, respectively. Also presented lower OPI values (averages: 28%/4% in Londrina, and 88%/60% in Manaus, respectively); and lower EDI values (averages: 10.5/9 in Londrina, and 47/30 in Manaus, respectively). The capture ratios of Aedes adults in the UELtrap-EA and CRtrap-EA traps in Londrina and Manaus were 53.3%/29.5% and 0%/9.8%, respectively. UELtrap-EA can be adopted as efficient tool for Aedes monitoring due to their high sensitivity, low cost and ease of use.
对埃及伊蚊（林奈）和白纹伊蚊（斯库斯）传播的虫媒病毒的控制可通过监测和减少这些病媒传播的工具来实现。因此，在野外评估了四种类型的诱捕器与生物制品Vectobac WG一起捕获埃及伊蚊和白纹伊蚊卵及成虫的效率。为此，20个诱捕器分别于2017年3月至4月和2018年1月至2月安装在巴西南部（巴拉那州隆德里纳）和北部（亚马孙州马瑙斯）的两个地点。UELtrap - E（标准诱捕器）和UELtrap - EA诱捕器捕获了埃及伊蚊和白纹伊蚊的卵：在隆德里纳分别捕获了1703/1866枚卵，在马瑙斯分别捕获了10268/2149枚卵，并且呈现出较高的诱卵器阳性指数（OPI）值（平均值：在隆德里纳分别为100%/100%，在马瑙斯分别为100%/96%）；以及较高的卵密度指数（EDI）值（平均值：在隆德里纳分别为68/75，在马瑙斯分别为411/89），所以在两个地区它们在统计学上的效率均优于CRtrap - E和CRtrap - EA诱捕器，后者捕获的卵和成虫较少：在隆德里纳分别捕获了96/69枚卵，在马瑙斯分别捕获了1091/510枚卵。同时它们的OPI值也较低（平均值：在隆德里纳分别为28%/4%，在马瑙斯分别为88%/60%）；以及较低的EDI值（平均值：在隆德里纳分别为10.5/9，并在马瑙斯分别为47/30）。在隆德里纳和马瑙斯，UELtrap - EA和CRtrap - EA诱捕器中埃及伊蚊成虫的捕获率分别为53.3%/29.5%和0%/9.8%。由于UELtrap - EA具有高灵敏度、低成本和使用方便的特点，可作为监测埃及伊蚊的有效工具。
