Companion planting is a well-known strategy to manage insect pests and support a natural enemy population through vegetative diversification. Trap cropping is one such type of special companion planting strategy that is traditionally used for insect pest management through vegetative diversification used to attract insect pests away from the main crops during a critical time period by providing them an alternative preferred choice. Trap crops not only attract the insects for feeding and oviposition, but also act as a sink for any pathogen that may be a vector. Considerable research has been conducted on different trap crops as companion plant species to develop improved pest management strategies. Despite this, little consensus exists regarding optimal trap cropping systems for diverse pest management situations. An advantage of trap cropping over an artificially released natural enemy-based biological control could be an attractive remedy for natural enemies in cropping systems. Besides, many trap crop species can conserve natural enemies. This secondary effect of attracting natural enemies may be an advantage compared to the conventional means of pest control. However, this additional consideration requires a more knowledge-intensive background to designing an effective trap cropping system. We have provided information based on different trap crops as companion plant, their functions and an updated list of trap cropping applications to attract insect pests and natural enemies that should be proven as helpful in future trap cropping endeavors.
间作套种是一种通过植物多样化来防治害虫和维持天敌种群数量的著名策略。诱集种植是一种特殊的间作套种策略，传统上用于害虫管理，通过植物多样化在关键时期为害虫提供替代的首选植物，从而将害虫从主要作物上吸引过来。诱集作物不仅能吸引昆虫取食和产卵，还能作为任何可能作为传播媒介的病原体的宿主。人们对不同的诱集作物作为伴生植物进行了大量研究，以制定更好的害虫管理策略。尽管如此，对于不同害虫管理情况的最佳诱集种植系统，目前还没有达成共识。与基于人工释放天敌的生物防治相比，诱集种植的一个优势可能是对种植系统中的天敌具有吸引力。此外，许多诱集作物物种可以保护天敌。与传统的害虫防治方法相比，这种吸引天敌的附带效果可能是一个优势。然而，要设计一个有效的诱集种植系统，这种额外的考虑需要更专业的知识背景。我们提供了基于不同诱集作物作为伴生植物的信息、它们的功能以及诱集种植应用的最新列表，以吸引害虫和天敌，这些信息在未来的诱集种植实践中应该会有所帮助。
