ICB/PPGBAIP Distribuição espacial de criadouros de Aedes (Stegomyia) aegypti Linnaeus 1762 (Diptera: Culicidae) em pontos georreferenciados de dois bairros da cidade de Macapá-AP: área endêmica de dengue

Abstract

The present work had as objective to study the spatial distribution of the breeding places of the Aedes (Stegomyia) aegypti Linnaeus 1762 Diptera: Culicidae) at geo referenced places of two districts of the Macapá-AP city. The specimens were collected in two periods (dry and rainy) and analyzed qualitatively and quantitatively. It was done mapping of buildings inspected, emphasizing those with positive breeding places for immature ways of A. aegypti, besides interviews with the local residents, in order to avaliate social economic aspects related to the occurrence of the species in question. In the “Trem” district, the moveable deposits, detained 21,90% of the worms collected at the dry period and 24,60% at the rainy period; fixed deposits 22,38% at the dry period and 20,59% at the rainy period; and the moveable deposits 49,05% at the dry period and 48,93% at the rainy period. In the “Cidade Nova” district the cesspools and deposits of water for consumption, detained 26,79% and 18,66% respectively. At the rainy period, the deposits of water for consumption increased to 34,16%, the cesspools maintained unaltered; suggesting that the latter is considered a preferred container for the spawning of the mosquito. It was evidenced that the canalized water supply covers 93% of the residences in the “Trem” district and 73% for the “Cidade Nova” district, which has no network of sanitary sewage. In the “Trem” district there were regular variability in the distribution of breeding places in the two periods studied. In the “Cidade Nova” district the spatial behavior presented a tendency of irregular variability, being possible to define the existing risk areas in relation to the type of breeding places. In a general run, it was concluded that one of the greatest capabilities of the analysis of geo referenced data is its manipulation to produce new information that contribute to a better management of the measures of control.
