Abstract

In response to herbivory, plants employ several inducible defenses to mitigate herbivore damage. These plant-induced responses can trigger subtle changes in plant metabolite composition, altering the profiles of plant-produced exudates such as (extra-) floral nectar and plant guttation. Natural enemies consume these plant-produced exudates, which serve as consistent and nutrient-dense food sources. There is mounting evidence that natural enemies’ access to plant-produced exudates impacts their fitness, performance, and life history traits. Nonetheless, the role of induced plant defense on plant-produced exudates and the subsequent effect on natural enemies remains under-researched. This review, thus, highlights the potential role of induced plant defense on the profiles of plant-produced exudates, with a particular emphasis on altered metabolic changes affecting resource nutritional value and consequently the fitness and performance of natural enemies. Future directions and potential implications in biological control practices are also highlighted.

诱导植物抗性及其对天敌利用植物衍生食品的影响。

为了应对食草动物的侵害，植物采用了几种可诱导的防御措施来减轻食草动物的伤害。这些植物诱导的反应会引发植物代谢物组成的微妙变化，改变植物产生的渗出物（如（花外）花蜜和植物内脏）的特征。天敌消耗这些植物分泌的渗出物，作为稳定的营养丰富的食物来源。越来越多的证据表明，天敌获取植物分泌的渗出物会影响其适应性、表现和生活史特征。然而，关于诱导植物防御对植物分泌的渗出物的作用以及随后对天敌的影响的研究仍然不足。因此，本综述强调了诱导植物防御对植物产生的渗出物的潜在作用，特别强调了影响资源营养价值的新陈代谢变化，进而影响天敌的适应性和表现。此外，还强调了生物防治实践的未来方向和潜在影响。

期刊介绍： Current Opinion in Insect Science is a new systematic review journal that aims to provide specialists with a unique and educational platform to keep up–to–date with the expanding volume of information published in the field of Insect Science. As this is such a broad discipline, we have determined themed sections each of which is reviewed once a year. The following 11 areas are covered by Current Opinion in Insect Science. -Ecology -Insect genomics -Global Change Biology -Molecular Physiology (Including Immunity) -Pests and Resistance -Parasites, Parasitoids and Biological Control -Behavioural Ecology -Development and Regulation -Social Insects -Neuroscience -Vectors and Medical and Veterinary Entomology There is also a section that changes every year to reflect hot topics in the field. Section Editors, who are major authorities in their area, are appointed by the Editors of the journal. They divide their section into a number of topics, ensuring that the field is comprehensively covered and that all issues of current importance are emphasized. Section Editors commission articles from leading scientists on each topic that they have selected and the commissioned authors write short review articles in which they present recent developments in their subject, emphasizing the aspects that, in their opinion, are most important. In addition, they provide short annotations to the papers that they consider to be most interesting from all those published in their topic over the previous year.
