Resumen:
The mosquito Aedes aegypti is
the main urban vector responsible for the transmission of dengue fever
and
dengue hemorrhagic fever. The city of Buenos Aires,
Argentina,
is located at the southern end of the world distribution of the species. The
population abundance of Ae. aegypti is mainly regulated by environmental
factors. We calculated the potential
number of times that a female could lay eggs during its mean life expectancy, based
on potential egg production and daily meteorological records. The model
considers those variables implying physical hazard to the survival of Ae.
aegypti, mosquito flying activity and
oviposition. The results, obtained after calibration and validation of the
model with field observations, show significant correlation (P<0.001) for
different lags depending on the life stage. From these results, more favorable atmospheric
conditions for Ae. aegypti reproduction (linked to the urban climatic change) can be observed. The climatic
variability in the last decade resembles conditions at the end of 19th century.
