摘要

摘要菌根共生影响植物生长和营养，并可能影响昆虫食草动物的表现，但这些影响取决于环境。本研究旨在研究氮肥和菌根共生对玉米和甜菜夜蛾生产性能的影响，并探讨潜在的潜在机制。菌根促进玉米生长，降低甜菜的生长性能，但这些影响取决于氮的有效性。然后，我们评估了甜菜夜蛾的后果是否是由其肠道微生物群介导的。氮和菌根都不影响甜菜根霉菌的肠道细菌群落。食草动物性能的降低可能是由于氮-菌根相互作用对植物营养价值的影响。

Mycorrhizal benefits on plant growth and protection against Spodoptera exigua depend on N availability

ABSTRACT Mycorrhizal symbiosis influences plant growth and nutrition and can affect the performance of insect herbivores, but these effects are context-dependent. This study aims to investigate the influence of nitrogen fertilization and mycorrhizal symbiosis on maize and Spodoptera exigua performance and to explore the potential underlying mechanisms. Mycorrhiza promoted maize growth and reduced S. exigua performance, but these effects were dependent on nitrogen availability. We then assessed whether the consequences for S. exigua were mediated by its gut microbiota. Neither nitrogen nor mycorrhization affected S. exigua gut bacterial community. Reduced herbivore performance was instead potentially due to the effects of nitrogen-mycorrhiza interaction on the plant nutritional value.
