Arthropod natural enemies (ANEs) play an indispensable role in maintaining the balance for plant communities that also significantly affects the ANE diversities not only by supporting herbivorous prey, but also by providing habitats and floral food resources. Studying the diversity of ANEs is thus vital to develop an understanding of sustainable pest control. Relationships of the vegetation diversity (including richness, coverage, and Shannon–Wiener diversity) with associated arthropod aphidophagous natural enemies (AANEs) and their groups under Pinus tabuliformis of different distances were analyzed by non-metric multidimensional scaling (metaMDS). Our results indicated that the vegetation richness affects AANEs at a small scale, while the vegetation structure affects it at a large scale. The richness and abundance of AANEs and the abundance of green lacewings (GLs) and aphid parasitoids (APs) were positively related to neighboring tree richness. But the richness of AANEs and aphidophagous ladybirds (ALs) were negatively associated with nearby tree coverage, as well as AANE richness with close-up shrub coverage, while the abundance of AANEs, ALs, and GLs possessed a negative and hump-shaped relationship with nearby tree coverage, as well as the abundance of AANEs and GLs with close-up shrub coverage. When tree and shrub layers each had approximately half coverage within a vegetation structure, the richness and abundance of AANEs were highest. Similarly, the richness and abundance of AANEs were positively related to neighboring blooming plant richness. However, the richness of AANEs and ALs, and the abundance of AANEs, AL, GL, and APs had a positive association either with the coverage or with the Shannon–Wiener diversity of close-up blooming plants. Half coverage of the tree and shrub layer combined with higher diversities (richness, coverage, and Shannon–Wiener diversity) of blooming plants resulted in low aphid density. The results provide a basis for effectively improving AANE diversity.

节肢动物天敌 (ANE) 在维持植物群落平衡方面发挥着不可或缺的作用，植物群落的平衡也显着影响 ANE 的多样性，不仅通过支持草食性猎物，而且通过提供栖息地和花卉食物资源。因此，研究 ANE 的多样性对于了解可持续害虫控制至关重要。油松下植被多样性（包括丰富度、覆盖度和香农-维纳多样性）与相关节肢天敌（AANEs）及其类群的关系通过非度量多维尺度 (metaMDS) 分析了不同距离的距离。我们的研究结果表明，植被丰富度对 AANEs 的影响较小，而植被结构对其影响较大。AANEs 的丰富度和丰度以及绿色草蛉 (GLs) 和寄生蚜虫 (APs) 的丰度与邻近树木的丰富度呈正相关。但是 AANEs 和蚜虫瓢虫 (ALs) 的丰富度与附近的树木覆盖率呈负相关，AANE 的丰富度与近距离灌木覆盖率呈负相关，而 AANEs、ALs 和 GLs 的丰度与附近的树木覆盖率呈负相关且呈驼峰状关系。附近的树木覆盖，以及丰富的 AANE 和 GL 以及近距离灌木覆盖。当乔木和灌木层在植被结构中各有大约一半的覆盖率时，AANEs的丰富度和丰度最高。同样，AANE 的丰富度和丰度与邻近开花植物的丰富度呈正相关。然而，AANE 和 AL 的丰富度，以及 AANE、AL、GL 和 AP 的丰富度与近距离开花植物的覆盖范围或香农-维纳多样性呈正相关。乔木和灌木层的半覆盖率以及开花植物的较高多样性（丰富度、覆盖率和香农-维纳多样性）导致蚜虫密度较低。研究结果为有效提高AANE多样性提供了依据。AP 与近距离开花植物的覆盖范围或香农-维纳多样性呈正相关。乔木和灌木层的半覆盖率以及开花植物的较高多样性（丰富度、覆盖率和香农-维纳多样性）导致蚜虫密度较低。研究结果为有效提高AANE多样性提供了依据。AP 与近距离开花植物的覆盖范围或香农-维纳多样性呈正相关。乔木和灌木层的半覆盖率以及开花植物的较高多样性（丰富度、覆盖率和香农-维纳多样性）导致蚜虫密度较低。研究结果为有效提高AANE多样性提供了依据。
