The common bed bug, L., is a pervasive pest of humans throughout the world. Insecticide resistance, cryptic habits, and proclivity for harborage on human belongings have contributed to its global status as a difficult pest to control. Leaves from common bean plants, L., which include numerous trichomes, have traditionally been used to capture wandering bed bugs in southeastern Europe. However, fresh leaves rapidly desiccate once removed from plants, losing their trapping ability. A leaf-derived trapping material was developed that does not desiccate as rapidly as fresh leaves and retains the potential to trap bed bugs. In this study, we tested the efficacy of the leaf-derived material in capturing bed bugs. We tested the leaf-derived material in both horizontal and vertical orientations, using fresh bean leaves as positive controls. When deployed horizontally, the leaf-derived material captured bed bugs of all life stages and both sexes (adults). Leaf-derived material was also found to capture bed bugs in a vertical orientation (only evaluated for adult male bed bugs). Because this experimental leaf-derived material was effective in both horizontal and vertical orientations and against all life stages, it may have great potential for development into bed bug monitoring or exclusion devices.
普通臭虫，即温带臭虫，是一种在全球范围内广泛侵扰人类的害虫。抗药性、隐匿习性以及倾向于在人类物品上栖息，使其在全球范围内成为一种难以控制的害虫。菜豆植株的叶子，包含大量毛状体，在东南欧传统上被用于捕捉四处爬行的臭虫。然而，新鲜叶子一旦从植株上摘下就会迅速干枯，失去捕捉能力。一种由叶子衍生而来的捕捉材料被开发出来，它不像新鲜叶子那样迅速干枯，并且保留了捕捉臭虫的潜力。在本研究中，我们测试了这种由叶子衍生而来的材料捕捉臭虫的效果。我们在水平和垂直方向上测试了这种由叶子衍生而来的材料，使用新鲜豆叶作为阳性对照。当水平放置时，这种由叶子衍生而来的材料能捕捉所有生命阶段和两性（成虫）的臭虫。还发现这种由叶子衍生而来的材料在垂直方向上也能捕捉臭虫（仅对成年雄性臭虫进行了评估）。由于这种实验性的由叶子衍生而来的材料在水平和垂直方向上以及针对所有生命阶段都有效，它可能具有极大的潜力被开发成臭虫监测或隔离装置。
