Shelter‐building insects are important ecosystem engineers, playing critical roles in structuring arthropod communities. Nonetheless, the influence of leaf shelters and arthropods on plant–associated microbiota remains largely unexplored. Arthropods that visit or inhabit plants can contribute to the leaf microbial community, resulting in significant changes in plant–microbe interactions. By artificially constructing leaf shelters, we provide evidence that shelter‐building insects influence not only the arthropod community structure but also impact the phyllosphere microbiota. Leaf shelters exhibited higher abundance and richness of arthropods, changing the associated arthropod community composition. These shelters also altered the composition and community structure of phyllosphere microbiota, promoting greater richness and diversity of bacteria at the phyllosphere. In leaf shelters, microbial diversity positively correlated with the richness and diversity of herbivores. These findings demonstrate the critical role of leaf shelters in structuring both arthropod and microbial communities through altered microhabitats and species interactions.

树叶庇护所促进节肢动物的定殖并增强植物上的微生物多样性


建造庇护所的昆虫是重要的生态系统工程师，在构建节肢动物群落中发挥着关键作用。尽管如此，树叶庇护所和节肢动物对植物相关微生物群的影响在很大程度上仍未得到探索。访问或栖息于植物的节肢动物可以为叶子微生物群落做出贡献，从而导致植物与微生物相互作用的显着变化。通过人工建造树叶庇护所，我们提供的证据表明，建造庇护所的昆虫不仅影响节肢动物群落结构，而且还影响叶际微生物群。树叶庇护所表现出更高的节肢动物丰度和丰富度，改变了相关节肢动物群落的组成。这些庇护所还改变了叶际微生物群的组成和群落结构，促进了叶际细菌的丰富度和多样性。在树叶庇护所中，微生物多样性与食草动物的丰富度和多样性呈正相关。这些发现证明了树叶庇护所通过改变微生境和物种相互作用来构建节肢动物和微生物群落的关键作用。
