Abstract

Ants occurring in urban areas have been focus of studies in recent years, however, the myrmecofauna of many regions remains unknown. The objective of this study was to evaluate the richness and abundance of ant assemblages in urban environments in the northwestern region of Rio Grande do Sul. Five cities of the region were sampled in two types of environments: squares and vacant lots. Samples were obtained between February and May 2018, using glucose and sardine baits and manual collection. A total of 9,772 specimens of ants were sampled, 468 occurrences were registered, and 57 species belonging to 19 genera and five subfamilies were identified. The richest genera in the samples were Pheidole (S = 13), Linepithema (S =7) and Camponotus (S = 6). This work contributes to the knowledge of ant assemblages in urban environments and the impacts of anthropization on biodiversity.
