在撒哈拉以南非洲的许多地区，针对室内寻找宿主的蚊子进行有效的疟疾病媒控制，减少了进入房屋的病媒，而户外病媒的比例在这种疾病的传播中变得越来越重要。本研究旨在开发一种用于野外采集疟疾媒介冈比亚按蚊的妊娠诱捕器。基于对市售重力捕集器的评估和改进。实验在80 m2的半野外系统中进行，其中200只妊娠的冈比亚按蚊s.s.每晚都被释放比较了Box、CDC和Frommer上吸式妊娠诱捕器的效果。测试了Box gravid诱捕器，以确定诱捕器在水面上的存在和诱捕器的声音是否影响捕获量。使用电击网或向诱捕器中的水中添加洗涤剂来评估接近处理的蚊子。基于这些结果，开发并评价了一种新的妊娠诱捕器（OviART诱捕器），该诱捕器提供了一个开放、无障碍的产卵部位。Box和CDC妊娠诱捕器收集的蚊子数量相似（相对比率（RR）0.8，95%置信区间（CI）0.6-1.2; p = 0.284），而Frommer诱捕器捕获的蚊子数量减少70%（RR 0.3，95% CI 0.2-0.5; p < 0.001）。与开放池塘相比，当诱捕器位于充满水的盆上方时，接近盒式诱捕器的蚊子数量显著减少（RR 0.7 95%CI 0.6-0.7; p < 0.001）。这种效果并不是因为陷阱的声音。使用新的OviART诱捕器，捕获量增加了60%（RR 1.6，1.2-2.2; p = 0.001）。格拉维德湾 Gambiae s.s.雌虫在视觉上被产卵介质正上方存在的诱捕装置所阻止。根据这些调查，一个有效的妊娠陷阱，提供了开放的着陆空间产卵按蚊。
Effective malaria vector control targeting indoor host-seeking mosquitoes has resulted in fewer vectors entering houses in many areas of sub-Saharan Africa, with the proportion of vectors outdoors becoming more important in the transmission of this disease. This study aimed to develop a gravid trap for the outdoor collection of the malaria vector Anopheles gambiae s.l. based on evaluation and modification of commercially available gravid traps. Experiments were implemented in an 80 m2 semi-field system where 200 gravid Anopheles gambiae s.s. were released nightly. The efficacy of the Box, CDC and Frommer updraft gravid traps was compared. The Box gravid trap was tested to determine if the presence of the trap over water and the trap’s sound affected catch size. Mosquitoes approaching the treatment were evaluated using electrocuting nets or detergents added to the water in the trap. Based on the results, a new gravid trap (OviART trap) that provided an open, unobstructed oviposition site was developed and evaluated. Box and CDC gravid traps collected similar numbers (relative rate (RR) 0.8, 95% confidence interval (CI) 0.6–1.2; p = 0.284), whereas the Frommer trap caught 70% fewer mosquitoes (RR 0.3, 95% CI 0.2–0.5; p < 0.001). The number of mosquitoes approaching the Box trap was significantly reduced when the trap was positioned over a water-filled basin compared to an open pond (RR 0.7 95% CI 0.6–0.7; p < 0.001). This effect was not due to the sound of the trap. Catch size increased by 60% (RR 1.6, 1.2–2.2; p = 0.001) with the new OviART trap. Gravid An. Gambiae s.s. females were visually deterred by the presence of the trapping device directly over the oviposition medium. Based on these investigations, an effective gravid trap was developed that provides open landing space for egg-laying Anopheles .
