Bombus terrestris bee (Bt) is an efficient pollinator, providing important ecosystem services in Europe and surroundings, where it is native. Colonies of Bt have been largely created for agricultural pollination and internationally marketed, including in countries outside their natural range. Bt has, deliberately or accidentally, escaped from greenhouses confinement to natural environments and, in many cases, has became an invasive species. When it becomes an invasive species, Bt is a strong competitor with other bees and various environmental impacts have been reported. In South America, Bt was introduced in natural environments of Chile and expanded its invasive distribution to Argentina. Recently, it was discussed the possibility of the species reaches Brazil, expanding its distribution through the corridors of climatic affinities since the areas that have already been invaded in South America, raising concerns about potential impacts to natural and agricultural systems. This research will use a multidisciplinary approach - it will join statistical and computational technologies to study biogeography and ecology - to detect corridors that are favorable to distributional shifting and expanding of Bt in South America, as well as the possibilities of Bombus terrestris reaches Brazil. The impact of a possible pervasive presence of Bt in agriculture, natural systems and in some species of native pollinators will be estimated in Brazil. Future climate change scenarios will be considered, in order to predict the dynamic expansion of the species along the time. This research also aims to contribute providing further information to definition of preventive and mitigation activities, action plans, and political and scientific decision-making.
