A mark-release-recapture study was conducted to refine the "push-pull" strategy for controlling the dengue, chikungunya, and Zika virus vector in a peridomestic environment by determining optimal locations and distances from human-occupied experimental huts for placement of the "pull" component (Biogents Sentinel™ [BGS] traps) to maximize the capture of mosquitoes. The BGS traps were placed at portals of entry (windows or doors) or corners of the experimental huts and at varying distances from the huts (0, 3, and 10 m). The location optimization trials revealed higher trap capture rates and reduction in entry of mosquitoes when the BGS traps were positioned nearer the experimental hut portals of entry than those placed in the corner of the huts. The trap capture rate at huts' portals of entry was 38.7% (116/300), while the corners recorded 23.7% (71/300). The percentage reduction in entry of mosquitoes into the huts was 69% and 31% at portals of entry and corners or vertices, respectively. In the distance optimization trials, the highest captures were recorded at 0 m (18.5%; 111/600) and 10 m (14.2%; 128/900) distances from the hut. Moreover, the highest percentage reduction in entry of mosquitoes into the huts occurred for traps set at 0 m (65.6%) compared with 3 m (17.2%) or 10 m (14.6%) distances from the huts.
开展了一项标记重捕研究，以优化“推拉”策略，该策略用于在居家周边环境中控制登革热、基孔肯雅热和寨卡病毒病媒介，具体方式是确定“拉”组件（Biogents Sentinel™ [BGS]诱捕器）放置在离有人居住的实验小屋的最佳位置和距离，从而最大限度地捕获蚊子。BGS诱捕器放置在实验小屋的入口处（窗户或门）或角落，并与小屋保持不同距离（0米、3米和10米）。位置优化试验表明，当BGS诱捕器放置在比小屋角落更靠近实验小屋入口处时，诱捕器的捕获率更高，进入小屋的蚊子数量减少。小屋入口处诱捕器的捕获率为38.7%（116/300），而角落处为23.7%（71/300）。蚊子进入小屋的减少百分比在入口处为69%，在角落或顶点处为31%。在距离优化试验中，离小屋0米（18.5%；111/600）和10米（14.2%；128/900）处的捕获量最高。此外，与距离小屋3米（17.2%）或10米（14.6%）处设置的诱捕器相比，离小屋0米处设置的诱捕器使进入小屋的蚊子减少百分比最高（65.6%）。
