| bloodmeal hosts of anopheles species (diptera: culicidae) in a malaria-endemic area of the brazilian amazon. | hosts of blood-fed anophelines (diptera: culicidae) were determined in three riverine villages, 1.5-7.0 km apart, along the matapí river, amapá state, brazil, by enzyme-linked immunosorbent assay midgut analysis for igg of common vertebrates. anopheles marajoara galvão & damsceno and anopheles darlingi root had higher human blood indices (hbi) than anopheles nuneztovari gabaldón, anopheles triannulatus (neiva and pinto), and anopheles intermedius (chagas), which were relatively zoophilic. hbis o ... | 2006 | 17017232 |
| emergence of a new neotropical malaria vector facilitated by human migration and changes in land use. | in a region of northeastern amazonia, we find a species previously of minor importance, anopheles marajoara, to be the principal malaria vector. in a total of five collections during 1996-97 in three replicated sites near the city of macapá, amapá state, this species occurs in much greater abundance compared with the presumed vector anopheles darlingi. also, a significantly higher proportion of an. marajoara is infected with malaria parasites, determined by the elisa technique. this appears to b ... | 2002 | 12135261 |
