Results of mosquito collections in two Ribeira Valley localities are presented. These places represents environments highly modified by agrarian and cattle raising activities. The collections were made by the aspiration method, in the search for resting mosquitoes, in all the domiciliary and peridomiciliary compounds, in the early morning. The use of the diversity index and similarity quotient on communities such as these that are tropically related gives some insight into resources and their distribution. So they are considered of great value for the endophily studies. Data obtained suggest that there is some degree of endophilic evolution in Ae. scapularis, Cx. ribeirensis and Cx. sacchettae. This behavior is subject to the influence of some extrinsic factors such as the density of cattle or other large domestic animals, and human behaviour in the management of the environment.
