[Shelters of mosquitoes Culex (Culex) in rural zones (Diptera: Culicidae)].
The human activities carried out in rural zones have been affecting the behavior of mosquitoes of the Culex (Culex) subgenera, which was the reason for undertaking this investigation with a view to registering data on the natural resting places in pastures and on the edge of or within primitive and residual forest areas. Three localities with different mesological conditions, as to type of human activity, all them situated in the Ribeira Valley region of S. Paulo State, Brazil, were chosen. The species most abundantly found were Cx. mollis (28.0%), Cx. declarator (25.0%), Cx. lygrus (13.0%) and Cx. coronator (9.6%). The collection of mosquitoes Cx. bidens + Cx. dolosus + Cx. chidesteri, known to be more urban, was much smaller than that of any other species of the group. With reference to outdoor environments, woodland contributed with 2,281 individuals (71.4%) suggesting their preference for this resting place, except for Cx. quinquefasciatus. Results are evaluated for the determination of the potential domicilation of each species and consequence of the same for the human population.
