The island of Cotijuba is located at 29km of Belém, Pará, Brazil. This island is of approximately 60 km2 and belongs to the Marajó archipelago. Cotijuba has reported repeated outbreaks of malaria during past years, especially in the months of April and May. Due to these outbreaks our interest focused on knowing the anopheline vectors in the island. From 2002 to 2004, periodic mosquito collections were made using human bait at landing and manual capture of resting specimens in the indoors and in the peridomicile. Six bi-monthly collections of 6 hours duration revealed only two man-attracted species: Anopheles (Nyssorhynchus) aquasalis and Anopheles (Anopheles) intermedius. Among other factors, climatic conditions, resident′s behavior and lack of resources for control measures contributed to the persistence of malaria in the Island of Cotijuba.
