Resumo:Ants are one of the most diverse insects amongst all animals. Studies in Ecuador are extensive in certain groups and regions, but there are many information gaps, especially for native and invasive species in urban areas. Linepithema humile is a worldwide invasive species, registered in Ecuador in 1990, but its information in the country is superficial. In this study, we analyze the diet preferences of L. humile to learn about its ecology in the area, its distribution patterns, and we evaluate the other species present in the Quito Valley. Using three types of baits, we found that, during the sampling season, L. humile preferred protein-rich diet. We hypothesize that dietary preferences for protein may be due to low protein availability in the ecosystem, or because they are undergoing a reproductive phase. Its distribution was analyzed with the records collected and in databases, showing that it is distributed mainly in urban areas. The distribution is linked to urban sprawl, which is causing its range to expand. Finally, with records and databases, a preliminary list of 20 species of ants present in the Quito Valley was made. This list of species represents the most complete list of ants and is the basis for future research studies in the Quito Valley.
