Abstract Here, we review the literature on the development and application of hydrogel compounds for insect pest management. Researchers have used hydrogel compounds for the past few decades to achieve the controlled release of various contact insecticides, but in recent years, hydrogel compounds have also been used to absorb and deliver targeted concentrations of toxicants within a liquid bait to manage insect pests. The highly absorbent hydrogel acts as a controlled-release formulation that keeps the liquid bait available and palatable to the target pests. This review discusses the use of various types of hydrogel compounds in pest management based on different environmental settings (e.g., agricultural, urban, and natural areas), pest systems (e.g., different taxa), and modes of insecticide delivery (e.g., spray vs bait). Due to their unique physicochemical properties, hydrogel compounds have great potential to be developed into new and efficacious pest management strategies with minimal environmental impact. We will also discuss the future research and development of hydrogels in this review.

水凝胶：从控制释放到害虫管理的新诱饵递送

摘要 在这里，我们回顾了有关水凝胶化合物在害虫防治中的开发和应用的文献。在过去的几十年里，研究人员一直使用水凝胶化合物来实现各种接触杀虫剂的控释，但近年来，水凝胶化合物也被用于吸收和释放液体诱饵中目标浓度的毒物，以控制害虫。高吸水性水凝胶作为一种控释制剂，可保持液体诱饵对目标害虫的可利用性和可口性。本综述讨论了基于不同环境设置（例如，农业、城市和自然区域）、害虫系统（例如，不同的分类群）和杀虫剂递送方式（例如，喷洒与饵）。由于其独特的物理化学性质，水凝胶化合物具有巨大的潜力，可以开发成对环境影响最小的新型有效害虫管理策略。我们还将在这篇综述中讨论水凝胶的未来研究和开发。
