Fertilization with dehydrated sewage sludge can speed up the recovery process of degraded areas due to nutrients concentration, favoring the development of pioneer plants such as Acacia auriculiformis A. Cunn. ex Beth (Fabales: Fabaceae) and the emergence of insects. This study aimed the evaluation of chewing, pollinating insects, predators, their ecological indices and relationships on A. auriculiformis plants fertilized with dehydrated sewage sludge. The experimental design was completely randomized with two treatments (with and without dehydrated sewage sludge) and 24 repetitions. The prevalence of chewing insects Parasyphraea sp. (Coleoptera: Chrysomelidae), Nasutitermes sp. (Blattodea: Termitidae), and Tropidacris collaris (Stoll, 1813) (Orthoptera: Romaleidae), defoliation, and ecological indices of abundance of Coleoptera and Orthoptera were observed on fertilized A. auriculiformis. Acacia auriculiformis plants, with a superior number of branches/tree, revealed greater abundance of Coleoptera and Orthoptera, species richness of pollinating insects, defoliation, numbers of Parasyphraea sp. and T. collaris. The ones with larger leaves/branches displayed greater abundance of species richness of Coleoptera and Diabrotica speciosa (Germar, 1824) (Coleoptera: Chrysomelidae). Therefore, the use of A. auriculiformis plants, fertilized with dehydrated sewage sludge, is promising in the recovery of degraded areas due to the ecological indices increase of chewing and pollinators insects and spiders in the analyzed area.
利用脱水污水污泥进行受精可以加速退化区域的恢复过程，因为营养物质的浓缩有利于先锋植物如 Acacia auriculiformis A. Cunn. ex Beth（豆科 Fabales：Fabaceae）和昆虫的出现。本研究旨在评估在经过脱水污水污泥施肥的 Acacia auriculiformis 植物上咀嚼、传粉昆虫、捕食者及其生态指数和关系。实验设计采用完全随机化，有两个处理（有和没有脱水污水污泥）和 24 个重复。在经过脱水污水污泥施肥的 Acacia auriculiformis 上观察到咀嚼昆虫 Parasyphraea sp.（鞘翅目：叶甲科）、Nasutitermes sp.（等翅目：白蚁科）和 Tropidacris collaris（Stoll，1813）（直翅目：蝗科）的流行、落叶和鞘翅目和直翅目昆虫丰度的生态指数。发现具有更多树枝/树的 Acacia auriculiformis 植物具有更高的鞘翅目和直翅目昆虫、传粉昆虫物种丰富度、落叶、Parasyphraea sp.和 T. collaris 的数量。具有更大叶片/树枝的植物显示出更高的鞘翅目和 Diabrotica speciosa（Germar，1824）（鞘翅目：叶甲科）物种丰富度的丰度。因此，由于分析区域中咀嚼和传粉昆虫以及蜘蛛的生态指数增加，使用经过脱水污水污泥施肥的 Acacia auriculiformis 植物有望在退化区域的恢复中发挥作用。
