BACKGROUNDPlant infestation by insect pests can alter plant physiology, thereby influencing the performance and behavior of subsequent herbivores and their natural enemies through indirect effects—changes in plant traits mediated by prior herbivory. This study investigates how prior infestation of Brassica rapa by the cabbage bug Eurydema ornata (Hemiptera: Pentatomidae) affects the aphid Myzus persicae (Hemiptera: Aphididae) and its natural enemies, the predator Harmonia axyridis Coleoptera: Coccinedllidae) and the parasitoid Aphidius gifuensis (Hymenoptera: Braconidae). To explore these interactions, we assessed aphid survival and fecundity, monitored population dynamics, examined the behavior of the predator and parasitoid, and analyzed plant volatile emissions.RESULTSOur findings revealed a significant reduction in M. persicae fecundity on E. ornata infested plants. Additionally, aphids showed a significantly lower frequency of entering the olfactometer arm loaded with odors emitted from infested plants compared to those with odors from healthy plants. Both natural enemies, H. axyridis and A. gifuensis, demonstrated stronger attraction to infested plants in preference and foraging bioassays. Volatile analysis revealed higher emissions from infested plants, with significant increases in key compounds, such as 3‐pentanol, (Z)‐3‐Hexenol, methyl isothiocyanate, dihydrojasmone, cis‐Jasmone, D‐Limonene, (E)‐β‐ocimene, β‐Elemene, (E)‐4,8–dimethyl–nonatriene and (E, E)‐⍺‐Farnesene.CONCLUSIONSE. ornata infestation reduces the suitability of B. rapa for M. persicae and enhances the biocontrol potential of its natural enemies. These interactions highlight the importance of intra‐guild competition and host manipulation in ecological, evolutionary and pest management perspectives. © 2025 Society of Chemical Industry.

甘蓝蝽 Eurydema ornata 先前的 Brassica rapa 侵扰改变了桃子-马铃薯蚜虫 Myzus persicae 及其天敌的性能和行为

背景害虫的侵扰可以改变植物生理机能，从而通过间接影响（先前食草介导的植物性状变化）影响后续食草动物及其天敌的表现和行为。本研究调查了卷心菜蝽 Eurydema ornata（半翅目：Pentatomidae）先前对 Brassica rapa 的侵扰如何影响蚜虫 Myzus persicae（半翅目：蚜虫科）及其天敌，捕食者 Harmonia axyridis 鞘翅目：Coccinedllidae）和寄生虫 Aphidius gifuensis（膜翅目：Braconidae）。为了探索这些相互作用，我们评估了蚜虫的存活和繁殖力，监测了种群动态，检查了捕食者和寄生虫的行为，并分析了植物挥发性排放。结果我们的研究结果显示，在 E. ornata 侵染的植物上，M. persicae 的繁殖力显着降低。此外，与具有健康植物气味的蚜虫相比，蚜虫进入载有受感染植物散发的气味的嗅觉计臂的频率显着降低。天敌 H. axyridis 和 A. gifuensis 在偏好和觅食生物测定中表现出对受感染植物的更强吸引力。挥发性分析显示，受侵染植物的排放量较高，关键化合物显著增加，例如 3-戊醇、（Z）-3-己烯醇、异硫氰酸甲酯、二氢茉莉酮、顺式茉莉烯、D-柠檬烯、（E）-β-罗勒烯、β-榄烯、（E）-4,8-二甲基-壬三烯和（E、E）-⍺-法呢烯。ornata 侵染降低了 B. rapa 对 M. persicae 的适应性，并增强了其天敌的生物防治潜力。这些互动突出了公会内部竞争和宿主纵在生态、进化和害虫管理方面的重要性。© 2025 化工学会.
