| 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 |
| malaria vector incrimination in three rural riverine villages in the brazilian amazon. | vector incrimination studies were conducted from april 2003 to february 2005 at three riverine villages 1.5 km to 7.0 km apart, along the matapi river, amapa state, brazil. a total of 113,117 mosquitoes were collected and placed in pools of <or=7 mosquitoes (19,883 pools) and tested for species-specific circumsporozoite protein (csp) of p. falciparum, p. vivax vk210, and p. vivax vk247 using the enzyme-linked immunoabsorbent assay (elisa). a subset of 63,330 mosquitoes (12,191 pools) was tested ... | 2007 | 17360868 |
| the physical gene hsp70 map on polytene chromosomes of anopheles darlingi from the brazilian amazon. | in situ hybridization was used to determine the physical location of the hsp70 genes in salivary polytene chromosomes of anopheles darlingi from manaus and macapá, brazil, and to assess the usefulness of the hsp70 locus as a genetic marker in a. darlingi populations. in both populations, the double markings corresponding to the hsp70-12a and hsp70-14a genes were located on the right arm of chromosome 2. the hsp70 locus was considered to be an excellent marker for studying chromosomal evolution a ... | 2004 | 15098741 |
| 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 |
| seasonal abundance of anopheline mosquitoes and their association with rainfall and malaria along the matapí river, amapá, [corrected] brazil. | three communities separated by 1.5-7.0 km, along the matapí river, amapá state, brazil, were sampled monthly from april 2003 to november 2005 to determine relationships between seasonal abundance of host-seeking anophelines, rainfall and malaria cases. out of the 759 821 adult female anophelines collected, anopheles darlingi root (diptera: culicidae) was the most abundant (56.2%) followed by an. marajoara galvão & damasceno (24.6%), an. nuneztovari gabaldón (12.4%), an. intermedius (chagas) (4.4 ... | 2009 | 19941599 |
| population structure of the malaria vector anopheles darlingi in a malaria-endemic region of eastern amazonian brazil. | anopheles darlingi is the primary malaria vector in latin america, and is especially important in amazonian brazil. historically, control efforts have been focused on indoor house spraying using a variety of insecticides, but since the mid-1990s there has been a shift to patient treatment and focal insecticide fogging. anopheles darlingi was believed to have been significantly reduced in a gold-mining community, peixoto de azevedo (in mato grosso state), in the early 1990s by insecticide use dur ... | 2006 | 16687683 |
