Temperature Rainfall |
Rainfall was important for the production
of larvae and pupae, but the rain period does not
coincide with maximum production. Abundance occurred in
the summer-autumn seasons, and the highest peak was
reached in March-April. Average temperature data
suggested that the 17-23° C range is the most
favorable to the vector’s larval
development. |

Relative humidity |
Representative values for temperature and
relative air humidity were shown; it is believed that
only the maximum temperatures exercise a strong
influence on the larvae population. In the months when
the highest indexes of relative air humidity occurred,
the highest means of the numbers of positive breeding
sites were observed. |

There was greater predominance of

A total of 7,825 immatures was obtained,

correlation with average temperature, rainfall and daily

The entomological indexes showed higher
values in the rainy period; the number of potential
breeding sites follows the rainfall pattern. The average
number of pupae per positive reservoir is intimately
associated with average temperature. Relative air
humidity also influenced the number of positive
reservoirs. |

The results of the collection of samples

Ae. albopictus was the dominant species
in all the tires. It was more abundant in the rainy

the volume of water was higher. Ae.

A positive correlation was found between:
positivity x rainfall (rs= 0.69; p <
0.001); positivity x temperature (rs= 0.35; p
< 0.001); number of individuals x rainfall
(rs= 0.29; p < 0.001) and number of
individuals x temperature (rs= 0.13; p <
0.05). The correlations suggest that rain was more
influent than temperature, and the highest frequencies
were observed in the hot and rainy period. |

Peaks of the epidemics were registered in
the beginning of the summer of each year; a relationship
was observed between the epidemic and temperature.
Rainfall levels were not significant. The period of
highest risk was considered: hot and dry summers, with
minimum average temperature above 22° C and rain
volume below 200 mm/month. |

The entomological indexes showed an
association between egg positivity and dengue incidence,

suggested that a monthly average temperature above

A positive correlation was verified between

the rain contributed to increase the number of breeding
sites, but it did not correlate with the incidence of
