Diversity of arthropods on (Fabaceae) and production of this plant with dehydrated sewage sludge in degraded area.

Sewage sludge is an organic matter-rich material with abundant fractions of nitrogen and other macro and micronutrients, essential for plant growth and development such as Willd. (Fabales: Fabaceae) used in recovering actions of degraded areas. The objective of this study was to evaluate over 24 months the abundance and diversity of chewing and pollinator insects and arthropod predators on plants and the mass production and soil coverage by this plant, fertilized with dehydrated sewage sludge, in a degraded area. The experimental design was in randomized blocks with two treatments (with and without dehydrated sewage sludge) and 24 replications. The number of leaves per branch and branches per plant, defoliation percentage by chewing insects, soil cover and abundance of chewing and pollinator insects and arthropod predators were higher on plants fertilized with dehydrated sewage sludge. sp. (Blattodea: Termitidae) and F. (Hymenoptera: Apidae) were the most observed insects on trunks and leaves, respectively, of plants fertilized with dehydrated sewage sludge. The fertilization increases the populations of different insect and spider groups on this plant.
