Human movement from rural areas to the cities has been intensified more and more over the past decades, culminating in a level on which never in the history of mankind so many people live in cities as they are today. As consequence cities are growing to accommodate its new residents, urbanizing adjacent peri-urban areas, expanding urban verticalization, and increasing the density of the human population. The role of construction sites in producing vector mosquitoes is unknown. Therefore, our goal is to analyze the impact of construction sites on the biodiversity of mosquitoes in Miami-Dade County. Collections of mosquitoes were performed weekly from August 2016 to July 2017 using two BG-Sentinel traps with dry ice, placed on the borders of the Miami Beach Convention Center construction site, located in Miami, Florida. Aedes aegypti and Culex quinquefasciatus accounted for 99% of all mosquitoes collected, both yielding 0.96 in the Simpson (1-D) index, and 3.97 and 4.02, respectively, in the Shannon (H) index. These findings strongly support the hypothesis that construction sites are promoting a biotic homogenization of species, favoring those species capable of thriving in anthropogenic environments, often with epidemiologic relevance.
