Abstract One of the most serious global problems is the decline of pollinator populations, so that various efforts are being made to monitor the biodiversity of bees, their conservation and sustainable use. Among the pollinators, bees are primarily responsible for the service of pollination of crops and maintenance of native ecosystems. However, several factors have contributed to the decrease in their diversity, including habitat loss, caused, among other factors, by the intensification of agriculture. Given the current status of the taxonomic impediment, a key area is the development and application of tools that allow us to access the intra and inter-specific alternative ways to traditional taxonomy. Molecular biology has allowed the development of methods in this area, including mitochondrial DNA by sequencing of regions to check the variability of haplotypes and evolutionary history of groups, essential data for defining conservation strategies, and microsatellites, which are essential for assessment of gene flow between wild populations. Beyond molecular biology, the use of computational tools for recognition of bee species using standards venation of the wings and geometric morphometrics has been of great importance for population studies. Recent data show the effectiveness of the technique for discrimination of species, and the variability of groups and recognition of individuals collected in different regions, enabling the tracking of the geographic origin of the species. Thus, this project aims to implement the aforementioned techniques in bee populations tribe Euglossini collected in different localities of the state of São Paulo in order to evaluate the variability of the population groups studied, discerning understanding of their evolutionary history, historical patterns and geographical and ecological effects that led to the current distribution of the genetic variability of the groups studied. | |
