Incidência Domiciliar e Extra-domiciliar do Anopheles aquasalis Curry, 1932 (Diptera: Culicidae) na Ilha de Mosqueiro da Grande Belém Insular, Pará

Abstract

The genus Anopheles includes all vectors of human malaria. Anopheles aquasalis Curry, 1932 (Diptera: Culicidae) is considered an important vector of this parasitic disease in Brazil, especially in coastal areas. The objective of this study was to verify the domiciliary and extra-domiciliary incidence of Anopheles aquasalis, considering that the observation of the hemophagic behavior of this species may be an important tool for malaria control in the study areas. Samples were collected in five areas on Mosqueiro Island, one at Marahú beach, another at the margins of the Mosqueiro Environmental Park, at Furo das Marinhas, Baía do Sol and Ariramba, from 18:00 to 00:00 h, using the human bait method. In the collections made during the low rainfall period, a total of 45 anopheline specimens were collected. In the areas of the Environmental Park and Furo das Marinhas, there were 100% attacks in the extra-household; on Marahú beach, 28.57% in the household and 71.42% in the extra-household; in Baía do Sol, 68.42% in the household and 31.57% in the extra-household; and in Ariramba, 8.4% in the household and 91.6% in the extra-household. In relation to hemophagic preference, in the rainy season, for the collection areas, the data show considerable difference in relation to the extra-household and the household. At the end of this study, we hope to conclude with consistent information on the behavior of Anopheles aquasalis at home and in the extra-household in the island of Mosqueiro.
