[Anthropophilic activity of Aedes aegypti and of Aedes albopictus in area under control and surveillance].
OBJECTIVE
To describe the hematophagous activity of Ae. aegypti and Ae. albopictus in an area under control and surveillance.


METHODS
The study was conducted during 18 months, from April, 1993 to October, 1994, in Cosmopolis, Sao Paulo state, Brazil. Human baits were used to collect mosquitoes. The number of females captured is presented monthly by area of the city and local in the household. The rainfall was measured and indices are presented without model adjustment.


RESULTS
The presence of females of both species was observed in 83% (Ae albopictus) and 61% (Ae. aegypti) of the period studied. The months of January, February and March presented the highest rates of activity for females of both species, with Ae. albopictus being more frequently captured than Ae. aegypti. Both species were captured in central and peripheral areas of the city, during the day from 9 to 12 am and from 4 to 7 pm. By a Poisson regression, it was observed that Ae. albopictus females were more frequently captured in the peri-housed area, in an independent way considering the area of the city.


CONCLUSIONS
It has been identified difference on the hematophagous activity only for Ae. albopictus, being of importance the outside area of the house.
