根据目前实施的情况，撒哈拉以南非洲的疟疾病媒监测的目标是内食和嗜内蚊子，导致外食（室外吸血）蚊子的数量不足。我们评估了最近开发的宿主诱捕器（HDT），并将其与金标准人类着陆诱捕器（HLC）进行了比较，在肯尼亚西部户外进行了3 × 3拉丁广场研究设计。与其他采样工具相比，hlc被认为代表了按蚊叮咬行为的自然范围，因此，原则上，它提供了传播疟疾的叮咬种群的最可靠概况。HDT结合了主要的宿主刺激，可以吸引寻找血液的蚊子，并可以用活宿主的气味作为诱饵。以人（HDT-H）或牛（HDT-C）气味为诱饵的高按蚊和高按蚊捕获的蚊子数量和种类多样性存在显著差异，揭示了按蚊种类行为的重要差异。在Kisian的主要研究中，HDT-C每晚平均采集43.2只按蚊（95% CI: 26.7-69.8），而HLC每晚平均采集5.8只按蚊（95% CI: 4.1-8.2），而HDT-H每晚平均采集0.97只按蚊（95% CI: 0.4-2.1），明显少于HLC。显著提高了An。每个捕获夜HDT-Cs和HDT-Hs的捕获值分别为（0.94±0.01；SE）和（0.76±0.09；SE），而HLCs的捕获值为（0.45±0.05；SE）。An的比例。冈比亚（s.s.）的HLC最高（0.55±0.05；SE），其次是HDT-H(0.20±0.09；SE)， HDT-C最低（0.06±0.01；SE）。放置在牛群通常整夜被圈养的地方旁边的无饵HDT捕获的大部分是An。有牛和无牛情况下，阿拉伯按蚊占按蚊总捕获量的比例分别为0.97±0.02和0.80±0.2。在牛附近平均捕获10.4只（95% CI: 2.0-55.0）按蚊/夜，而在远离宿主的无饵HDT中平均捕获0.4只（95% CI: 0.1-1.7）。HDTs结合宿主气味、热量和视觉刺激来模拟宿主的能力为对咬人和咬牛的蚊子进行取样的系统提供了基础。HDT-C对收集An特别有效。arabiensis户外。HDT提供了一种监测和潜在控制An的系统的前景。Arabiensis和其他户外蚊虫叮咬更有效。
As currently implemented, malaria vector surveillance in sub-Saharan Africa targets endophagic and endophilic mosquitoes, leaving exophagic (outdoor blood-feeding) mosquitoes underrepresented. We evaluated the recently developed host decoy trap (HDT) and compared it to the gold standard, human landing catch (HLC), in a 3 × 3 Latin square study design outdoors in western Kenya. HLCs are considered to represent the natural range of Anopheles biting-behaviour compared to other sampling tools, and therefore, in principle, provide the most reliable profile of the biting population transmitting malaria. The HDT incorporates the main host stimuli that attract blood-meal seeking mosquitoes and can be baited with the odours of live hosts. Numbers and species diversity of trapped mosquitoes varied significantly between HLCs and HDTs baited with human (HDT-H) or cattle (HDT-C) odour, revealing important differences in behaviour of Anopheles species. In the main study in Kisian, the HDT-C collected a nightly mean of 43.2 (95% CI: 26.7–69.8) Anopheles, compared to 5.8 (95% CI: 4.1–8.2) in HLC, while HDT-H collected 0.97 (95% CI: 0.4–2.1), significantly fewer than the HLC. Significantly higher proportions of An. arabiensis were caught in HDT-Cs (0.94 ± 0.01; SE) and HDT-Hs (0.76 ± 0.09; SE) than in HLCs (0.45 ± 0.05; SE) per trapping night. The proportion of An. gambiae (s.s.) was highest in HLC (0.55 ± 0.05; SE) followed by HDT-H (0.20 ± 0.09; SE) and least in HDT-C (0.06 ± 0.01; SE). An unbaited HDT placed beside locales where cattle are usually corralled overnight caught mostly An. arabiensis with proportions of 0.97 ± 0.02 and 0.80 ± 0.2 relative to the total anopheline catch in the presence and absence of cattle, respectively. A mean of 10.4 (95% CI: 2.0–55.0) Anopheles/night were trapped near cattle, compared to 0.4 (95% CI: 0.1–1.7) in unbaited HDT away from hosts. The capability of HDTs to combine host odours, heat and visual stimuli to simulate a host provides the basis of a system to sample human- and cattle-biting mosquitoes. HDT-C is particularly effective for collecting An. arabiensis outdoors. The HDT offers the prospect of a system to monitor and potentially control An. arabiensis and other outdoor-biting mosquitoes more effectively.
