Abstract

To ensure sustainable food production within agroecosystems, effective pest control is of utmost importance. One critical component of integrated pest management is biological control. The attraction, retention, and persistence of natural enemies within cropping systems are key factors for the success and effectiveness of biological control. Despite great efforts to attract and augment natural enemies in agroecosystems, little is known about the retention and persistence of their populations after they arrive at a crop field. Plant defensive traits play a critical role in shaping herbivore population dynamics, yet their impact on the structure of carnivorous arthropod communities and their contribution in boosting the success of biological control efforts remains understudied. Here, we discuss the role of plant defenses in retaining natural enemy communities by influencing the quality of herbivorous pests as prey for their natural enemies. These bottom-up effects of host-plant defenses on prey quality are often overlooked in the development of pest management strategies. However, these effects could serve as the foundation for novel applications of plant defenses in pest management.

评估植物防御能力对猎物质量的影响，以此为契机加强农业生态系统中的生物防治能力

为确保农业生态系统内的可持续粮食生产，有效的害虫控制至关重要。害虫综合防治的一个重要组成部分就是生物防治。在种植系统中吸引、保留和维持天敌是生物防治成功和有效的关键因素。尽管为吸引和增加农业生态系统中的天敌做出了巨大努力，但人们对天敌到达作物田后其种群的保留和持久性知之甚少。植物的防御性特征在形成食草动物种群动态方面起着至关重要的作用，但它们对食肉节肢动物群落结构的影响及其在提高生物防治成功率方面的贡献仍未得到充分研究。在这里，我们将讨论植物防御系统通过影响作为天敌猎物的食草害虫的质量来保持天敌群落的作用。在制定害虫管理策略时，寄主植物防御对猎物质量的这些自下而上的影响往往被忽视。然而，这些影响可以作为植物防御在害虫管理中的新应用的基础。

期刊介绍： Biological control is an environmentally sound and effective means of reducing or mitigating pests and pest effects through the use of natural enemies. The aim of Biological Control is to promote this science and technology through publication of original research articles and reviews of research and theory. The journal devotes a section to reports on biotechnologies dealing with the elucidation and use of genes or gene products for the enhancement of biological control agents. The journal encompasses biological control of viral, microbial, nematode, insect, mite, weed, and vertebrate pests in agriculture, aquatic, forest, natural resource, stored product, and urban environments. Biological control of arthropod pests of human and domestic animals is also included. Ecological, molecular, and biotechnological approaches to the understanding of biological control are welcome.
