[Breeding places of Aedes scapularis (Diptera: Culicidae) in artificial containers]

Breeding places of Aedes scapularis were found in the Ilha Comprida and Pariquera-Açu counties of S. Paulo State, Brazil. They included several types of artificial water container. As 270 (250 larvae and 20 pupae) immature forms were collected, the hypothesis is raised that behavioral change is occurring as a secondary adaptation, as a consequence of the anthropic environment. This tends toward a reduction in ground breeding places and, at the same time, to an increase in the number of artificial containers. So the synanthropic tendence of thus mosquito may be favored by or even be a result of the man-made environment. Reference is made to the epidemiological consequences of this phenomenon for encephalitis transmission specifically for the Southeastern region of Brazil.
