| Sumario: | <p>Some species of wasps demonstrate plasticity with diverse nesting habits according to the environmental conditions and substrates used for building the nests, while others are restricted to habitats with specific conditions and may exhibit some degree of fide-lity. The aim of this study was to estimate species richness and abundance of nests of Polistini and Epiponini wasps in four landscape units in the Pantanal of Poconé, Retiro Novo Farm, southwestern Mato Grosso state, Brazil. The nests of social wasps were sampled in four plant physiognomies locally known as cambarazal, landizal, pombeiral and campo limpo from August 25, 2011 to April 11, 2012, being recorded 308 nests of eight genera and 14 species of social wasps. The highest number of nests belongs to <em>Polybia ruficeps xanthops</em> (32.69%), <em>Poly. sericea</em> (24.27%) and <em>Synoeca surinama</em> (15.21%). The highest species richness was recorded in cambarazal and the highest abundance of nests in pombeiral, while campo limpo showed the lowest richness and abundance of nests. The nests of <em>S. surinama</em> were associated with cambarazal and landizal (IndVal = 93.3, P = 0.001), while the nests of Poly. ruficeps xanthops and <em>Poly. chrysothorax</em> were associated with cambarazal, landizal and pombeiral (IndVal = 97, P = 0.001). There was lower abundance and lower species richness of wasps in campo limpo. These results demonstrate that the maintenance of forest environments in the Pantanal is essential for the establishment and maintenance of social wasp nests.</p> |
