Incidência domiciliar e extra-domiciliar do anopheles aquasaliscurry, 1932 (diptera: culicidae) nas ilhas de Cotijuba e 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. It is a species that presents a very eclectic behavior and, depending on the population where it occurs, it may vary its hemophagic behavior. This study aimed 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. Collections were made in two areas of Mosqueiro Island, one at Mahaú beach and the other at the margins of the Mosqueiro Environmental Park, from 6:00 PM to midnight, using the human bait method. To date, a total of 649 anopheline specimens have been collected, 95.53% of which were obtained from the Mahaú Beach. In the Environmental Park area, we obtained 41.37% of attacks in the home and 58.62% in the out-of-home; on Mahaú beach, 53.22% in the home and 46.77% in the out-of-home. There was a higher incidence of anophelines in the Mahaú beach area. Regarding the hemophagic preference, so far, for the two collection areas, the data show little difference in relation to extra-household and home. There will be two more field trips during the rainy season and four more during the low rainy season (summer). At the end of the two periods we hope to conclude with consistent information on the behavior of Anopheles aquasalis at home and in the extra-home environment on the island of Mosqueiro.
