“…The presence of nests with protective envelopes allows better thermal regulation by individuals of the colony, which helps to maintain a temperature favorable for survival (HOzumi et al 2010). In other social insects of order Hymenoptera, temperatures in nests are not only regulated by the presence of a protective cover, but also by the materials used in their construction, the physical location, and the individuals' metabolic activity (wiLsOn 1972;zmitrOwicz 2001). Another aspect that was discussed in an altitudinal study carried out in Central America (Kumar et al 2009) is the correlation between the colony foundation with elevation in altitudes above 1,600, demonstrating that in higher altitudes there is a predominance of species with foundation by swarming.…”

Abstract. The Parque Estadual da Serra do Papagaio is the largest area of natural preservation in the south of Minas Gerais, with areas of Floresta Atlantica, Floresta de Araucaria and Campos de Altitude. Although this is an area of biological importance, there are many groups that have not yet been studied there: for example social wasps, which are insects belonging to order Hymenoptera, family Vespidae, which play an important ecological role in different ecosystems. This study was carried out in the aforementioned natural preservation area at altitudes between 1600 and 2200 m in 20 days of sampling between July of 2013 and April of 2014, using active searches and attractive traps to record species. Twenty two species of social wasps were sampled, distributed in seven genera. This number is small compared to counts from other studies in this state, which is probably due to the high altitude of this area. There was a predominance of nests with protective casings in the most common species recorded, and the most populous species was Polybia fastidiosuscula Saussure, a finding that can be explained by the superior thermoregulation afforded by the nest casing. Two other common species were Mischocyttarus drewseni Saussure, and Mischocyttarus rotundicolis (Cameron), which have nests without casings; however, these species have dark coloration, as does the substrate used for nesting, and can therefore enhance retention of solar radiation; nevertheless, other biotic and abiotic factors could be involved.
