ARTHROPODS LIFTING SURFACE SOIL IN THE AREA OF THE GRASSLANDS SETTLEMENT ALEGRIA, MARABÁ - PA

Abstract

ABSTRACT: Grazing areas are characterized by dynamic ecological flora and fauna that are dramatically affected by human interventions. Arthropods from the soil surface agroecossitemas these are directly affected by the reduction of resources required for their survival, thereby decreasing biodiversity and the interactions between organisms. The aim of this study was to survey the arthropods that inhabit the soil surface in two farms in Settlement Joy, Maraba - Para Thus, we installed four pitfall traps in pasture areas that remained in place for 72 hours, later arthropods caught in traps were counted and identified to family level. The specimens of the family Formicidae were those presented in greater quantity, followed the family Gryllidae and Scarabaeidae. These organisms perform functions relevant and essential for these agroecossitemas pasture, thus ensuring the maintenance of the means of production. KEYWORDS: Biodiversity, agroecosystens, ecological balance.
