A urbanizacao tem causado a fragmentacao de varios ambientes naturais, levando a perda de muitos processos ecologicos como a polinizacao, realizada principalmente por abelhas, em especial as especies de Meliponini, que tem reduzido drasticamente as suas populacoes devido a perda de habitat pela expansao urbana. O objetivo deste estudo foi realizar um levantamento das especies de abelhas sem ferrao em areas urbanas do municipio de Uba - MG, Brasil, relacionar a riqueza e abundância das especies encontradas com a taxa de ocupacao das variaveis estruturais da paisagem das areas urbana e relacionar a presenca das especies obtidos com estas variaveis. Foram encontrados 28 ninhos pertencentes a quatro especies, Tetragonisca angustula (Latreille), Trigona spinipes (Fabricius), Nannotrigona testaceicornis (Lepeletier) e Friesella schrottkyi (Friese). Nao houve relacao significativa entre a riqueza e abundância de Meliponini e variaveis estruturais de vegetacao analisadas, possivelmente devido a valores baixos no numero de ninhos e especies encontrados. Somente T. spinipes se mostrou relacionada com a presenca de vegetacao. Os resultados mostram que a comunidade Meliponini e composta por especies generalistas capazes de utilizar cavidades artificiais e plantas ornamentais como uma fonte alternativa de recursos, comuns em areas urbanas. Os resultados obtidos neste estudo servem de alerta para atuais condicoes dos remanescentes vegetais em areas urbanas na cidade de Uba, alem de tambem poderem ser usados como material de apoio na tomada de decisao sobre projetos de conservacao e recuperacao de areas degradadas, tendo como foco sobre as abelhas e sua importância para a sustentabilidade destes ecossistemas. Where the most Adapted Remain: Stingless Bees Community (Hymenoptera: Apidae, Meliponini) in Urban Areas of the City of Uba, Minas Gerais, Brazil Abstract. The urbanization has caused the fragmentation of various natural environments, taking to loss of many ecological processes in which includes pollination, realized mainly by bees, in special Meliponini species, which has drastically reduced their populations due to loss of habitat for urban expansion. The aim of this study was to survey the species of stingless bees in urban areas of the municipality of Uba - MG, Brazil, relate the richness and abundance of species found with the percentage of occupation of the structural variables of the urban landscape and relate the presence of the species obtained with these variables. Were found 28 nests belonging to four species, Tetragonisca angustula (Latreille), Trigona spinipes (Fabricius), Nannotrigona testaceicornis (Lepeletier) and Friesella schrottkyi (Friese). There was no significant relationship between richness and abundance of Meliponini and structural variables of vegetation, possibly due to low values in the number of nests and species obtained. Only T. spinipes showed related to the presence of vegetation. The results show that the Meliponini community is composed by generalist species able to use artificial cavities and ornamental plants as an alternative source of resources, common in urban areas. The results obtained in this study is a warning to current conditions of the plant remaining in urban areas in the city of Uba, besides may also be used as support in taking-decision on projects for the conservation and recovery of degraded areas, focusing on bees and their importance to the sustainability of these ecosystems.
