Results obtained through domiciliary catches of Culicidade mosquitoes in the "Vale do Ribeira" S. Paulo, Brazil are given on a study of the mechanisms of local encephalitis transmission. The same orientation for extra-domiciliary observation was followed. Significant presence of Aedes scapularis and Culex (Melanoconion) sp. in indoor catches suggested their participation in domiciliary transmission. This pattern was more evident in the rural areas than the urban ones. Association of these findings to the occurrence of clinical cases of the disease in young children is suggested.
