病媒监测将是消灭盘尾丝虫病的关键。宿主诱饵诱捕器(HDTS)捕获的Simulium比Eperanza窗户诱捕器多60倍。从HDT捕获的样本中解剖出一种单一的感染性钉螺幼虫。HDTS可支持消灭活动中的盘尾丝虫病监测。在许多国家消灭盘尾丝虫病是触手可及的，但需要加强对螺旋体盘尾丝虫病病媒的监测。采集足够数量的成虫来检测感染性的旋毛虫幼虫，由于这些苍蝇的采样工具有限而受到阻碍。在这里，我们首次测试了宿主诱饵陷阱(HDT)，这是一种以前为疟疾按蚊媒介开发的无暴露方法，作为一种潜在的成虫采样工具。在随机拉丁方实验设计的三个重复中，将HDT与人类落地捕获器(HLC)和埃斯佩兰萨窗户诱捕器(EWT)进行比较。在三种不同诱捕方法的渔获物中共发现8,531只成虫。HDT(平均捕获量533±1111)显著多于EWT(平均捕获量9.1±22.2)，相差近60倍。HLC平均捕获量为385.6±80.9，与HDT相比差异无统计学意义。从2.86%的HDT标本(n=470)和0.35%的HLC标本(n=285)中分离出与卷叶圆线虫无法区分的幼虫，在从HDT中分离到1例感染性三期幼虫(L3)。由于其捕获率非常高，与HLC相当，明显高于EWT，而且其捕获的渔获物中存在受感染的苍蝇，HDT是在需要数千只苍蝇进行寄生虫筛查的消灭环境中收集黑蝇的潜在有价值的新工具。寄主诱饵诱捕器是一种潜在的监测工具，在钉螺消灭活动中可以用来监测介体的传播。
Vector surveillance will be critical in the move towards onchocerciasis elimination. Host Decoy Traps (HDTs) caught 60 times more Simulium than esperanza window traps. A single infectious Onchocerca species larva was dissected from a sample caught by HDT. HDTs may support onchocerciasis surveillance in elimination campaigns. Onchocerciasis elimination is within reach in many countries but requires enhanced surveillance of the Simulium vectors of Onchocerca volvulus. Collection of sufficient numbers of adult Simulium to detect infective O. volvulus larvae is hindered by limited sampling tools for these flies. Here, we tested for the first time the Host Decoy Trap (HDT), an exposure free method previously developed for Anopheles vectors of malaria parasites, as a potential sampling tool for adult Simulium. In three replicates of a randomized Latin square experimental design, the HDT was compared to Human Landing Catches (HLC) and the Esperanza Window Trap (EWT). A total of 8,531 adult S. damnosum sensu lato blackflies (S. squamosum group) were found in catches from the three different trapping methods. The HDT (mean catch 533 ± 111) caught significantly more S. squamosum than the EWT (mean catch 9.1 ± 2.2), a nearly 60-fold difference. There was no significant difference between the HLC (mean catch 385.6 ± 80.9) and the HDT. Larvae indistinguishable from those of O. volvulus were dissected from 2.86% of HDT samples (n = 70) and 0.35% of HLC samples (n = 285); a single infective third-stage larvae (L3) was found during dissection of a sample from the HDT. Owing to its very high capture rate, which was comparable to the HLC and significantly greater than EWT, alongside the presence of infected flies in its catch, the HDT represents a potentially valuable new tool for blackfly collection in elimination settings, where thousands of flies are needed for parasite screening. Host Decoy Traps are a potential surveillance tool for Simulium vectors in onchocerciasis elimination campaigns.
