Abstract

The structure of the communities of ants is of particular interest as bio indicators given their importance in environmental impact studies, as they present abundance and species richness, specialized taxa, wide geographical distribution, easily sampled in addition to being sensitive to environmental changes. Considering the above, the objective of this study was to evaluate the effects on the diversity of myrmecofauna through the application of pig farming wastewater (0, 100, 200 and 300 m 3 ha -1 ) combined with nitrogen fertilization (0 and 100% of the recommended dose for culture) in typic dystroferric Red Latosol cultivated with baby corn. For evaluating the myrmecofauna, pitfall traps were installed and organisms classified in terms of gender. The Formicidae family had increased density to 200 m 3 ha -1 doses of pig farming wastewater, but without showing changes due to chemical fertilization. However, sorting the gender taxonomic level showed no significant effects on different groups, except for the Solenopsis genus, when it was used doses of 0 and 300 m 3 ha -1 of pig farming wastewater.

养猪场废水处理后土壤质量的生物指示剂——蜜蚁(膜翅目:蚁科)

蚂蚁群落的结构作为生物指标在环境影响研究中具有重要意义，因为它们具有丰富度和物种丰富度，专门的分类群，广泛的地理分布，易于采样以及对环境变化敏感。综上所述，本研究旨在评价猪场养殖废水(0、100、200和300 m 3 ha -1)与氮肥(0和100%推荐培养量)在典型的营养不良红Latosol中与幼玉米一起栽培对金蝇科动物多样性的影响。为了评价微栖动物，设置了陷阱，并按性别对生物进行了分类。食蚁兽科的密度增加到200 m 3 ha -1剂量的养猪场废水，但没有显示出化学施肥的变化。然而，当使用0和300 m 3 ha -1的养猪场废水时，除螺线管属外，对不同类群的分类水平均无显著影响。
