Acacia mangium (Willd., 1806) (Fabales: Fabaceae) is a fast growing, rustic, pioneer species, with potential to fix nitrogen, and for programs to recover degraded areas. The objective was to evaluate the distribution and the functional diversity of interactions and the K-dominance of arthropod groups on A. mangium saplings. The number of individuals of eleven species of phytophagous insects, three bee species, and fourteen natural enemy species were highest on the adaxial leaf surface of this plant. Abundance, diversity and species richness of phytophagous insects and natural enemies, and abundance and species richness of pollinators were highest on the adaxial A. mangium leaf surface. The distribution of five species of sap-sucking hemipterans and six of protocooperating ants (Hymenoptera), with positive interaction between these groups, and three bee species (Hymenoptera) were aggregated on leaves of A. mangium saplings. Aethalion reticulatum (L.) (Hemiptera: Aethalionidae) and Bemisia sp. (Hemiptera: Aleyrodidae); Brachymyrmex sp. and Camponotus sp. (Hymenoptera: Formicidae); and Trigona spinipes Fabricius (Hymenoptera: Apidae) were the most dominant phytophagous insects, natural enemies, and pollinators, respectively, on A. mangium leaves. Knowledge of preferred leaf surfaces could help integrated pest management programs.
相思树（Willd., 1806）（豆科：含羞草科）是一种生长迅速、适应性强的先锋物种，具有固氮潜力，适合恢复退化地区的项目。本研究旨在评估节肢动物组在相思树上的分布和功能多样性以及 K-优势度。在植物的叶正面，11 种食叶昆虫、3 种蜜蜂和 14 种天敌的个体数量最多。食叶昆虫和天敌的丰度、多样性和物种丰富度以及传粉者的丰度和物种丰富度在 A. mangium 叶的叶正面最高。五种吸食汁液的半翅目昆虫和六种合作蚂蚁（膜翅目）的分布以及这两个群体之间的正相互作用，以及三种蜜蜂（膜翅目）的分布在相思树苗的叶子上呈聚集分布。Aethalion reticulatum (L.)（半翅目：Aethalionidae）和Bemisia sp.（半翅目：Aleyrodidae）；Brachymyrmex sp.和Camponotus sp.（膜翅目：蚁科）；以及Trigona spinipes Fabricius（膜翅目：蜜蜂科）分别是相思树叶上最占优势的食叶昆虫、天敌和传粉者。对首选叶片表面的了解有助于综合虫害管理计划。
