| Abstract | OBJECTIVE: To evaluate dispersal of Aedes aegypti females in an area with
no container manipulation and no geographic barriers to constrain mosquito
fl ight.
METHODS: A mark-release-recapture experiment was conducted in December
2006, in the dengue endemic urban district of Olaria in Rio de Janeiro,
Southeastern Brazil, where there is no evident obstacle to the dispersal of Ae.
aegypti females. Mosquito traps were installed in 192 houses (96 Adultraps
and 96 MosquiTRAPs).
RESULTS: A total of 725 dust-marked gravid females were released and
recapture rate was 6.3%. Ae. aegypti females traveled a mean distance of
288.12 m and their maximum displacement was 690 m; 50% and 90% of
females fl ew up to 350 m and 500.2 m, respectively.
CONCLUSIONS: Dispersal of Ae. aegypti females in Olaria was higher than
in areas with physical and geographical barriers. There was no evidence of a
preferred direction during mosquito fl ight, which was considered random or
uniform from the release point. | pt_BR |
