Many vascular plants produce adhesive substances that may trap arthropods for their own protection, nutrition, and to engage in mutualistic relationships with predatory arthropods. While the role of stickiness in plant defense is well established, our understanding of the mechanisms and factors that determine the successful capture of arthropods by sticky plants and how we can utilize this knowledge to increase the sustainability of our agricultural practices is still limited. We review the literature on arthropod-trapping sticky plants and plant-based adhesive use in agriculture. There are many factors involved in the successful capture of arthropods by sticky plants, including: plant morphology, glue chemistry, the use of visual cues and volatiles to affect arthropod behavior, environmental factors, and adaptations of arthropods in their behavior, morphology, and chemistry to avoid being captured. Considering agricultural potential, using sticky crops as trap plants and ameliorating crops with sticky features could be useful for crop protection, but practical application is scarce. The same is true for the use of sticky plant specialist arthropod predators. Furthermore, plant-based adhesives are becoming more popular in agriculture for example, as glues for sticky traps, as sprayable adhesives for physical plant protection, and as carriers of botanicals and pesticides. So far, these adhesives see only small-scale use and are often less effective in the field than in the laboratory. Before plant stickiness and plant-based glues can be fully utilized for crop protection, several technological and resource related challenges must also first be overcome.
许多维管植物会产生粘性物质，这些物质可能会捕获节肢动物以实现自身保护、获取营养，并与捕食性节肢动物建立互利关系。虽然粘性在植物防御中的作用已得到充分证实，但我们对于决定粘性植物成功捕获节肢动物的机制和因素，以及如何利用这些知识来提高农业实践的可持续性的理解仍然有限。我们回顾了有关捕获节肢动物的粘性植物以及农业中基于植物的粘合剂使用的文献。粘性植物成功捕获节肢动物涉及许多因素，包括：植物形态、胶水化学性质、利用视觉线索和挥发物影响节肢动物行为、环境因素，以及节肢动物在行为、形态和化学方面为避免被捕获而做出的适应性变化。考虑到农业潜力，将粘性作物用作诱捕植物以及改良具有粘性特征的作物可能对作物保护有用，但实际应用很少。使用粘性植物特化的节肢动物捕食者的情况也是如此。此外，基于植物的粘合剂在农业中越来越受欢迎，例如，用作粘性诱捕器的胶水、用于物理植物保护的可喷雾粘合剂，以及植物提取物和农药的载体。到目前为止，这些粘合剂仅在小规模使用，并且在田间通常不如在实验室中有效。在植物粘性和基于植物的胶水能够完全用于作物保护之前，还必须首先克服一些与技术和资源相关的挑战。
