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 of An. darlingi varied significantly among villages, attributable to a low proportion of human-fed mosquitoes in Santo Antônio. Significantly higher incidence of An. marajoara and An. nuneztovari fed on pig blood at two villages, associated with a low number of pigs in Santo Antônio. The incidences of bovine blood varied significantly among villages for all three of the most common anopheline species. The incidence of mixed meals ranged from 7.1 to 27.6% among common species, and, for An. marajoara, varied significantly among villages. This study demonstrates differences in host selection patterns among villages only a few kilometers apart, which may be influenced by host availability and have important epidemiological consequences.
通过针对常见脊椎动物IgG的酶联免疫吸附测定中肠分析法，在巴西阿马帕州马塔皮河沿岸相距1.5 - 7.0公里的三个河滨村庄，确定了吸食血液的按蚊（双翅目：蚊科）的宿主。马拉若按蚊Galvão & Damsceno和达林按蚊Root的人血指数（HBI）高于努涅斯按蚊Gabaldón、三带按蚊（Neiva和Pinto）和中间按蚊（Chagas），后几种按蚊相对嗜动物性。达林按蚊的HBI在不同村庄间差异显著，这是由于圣安东尼奥村吸食人血的蚊子比例较低。在两个村庄，马拉若按蚊和努涅斯按蚊吸食猪血的发生率显著更高，这与圣安东尼奥村猪的数量较少有关。所有三种最常见按蚊种类吸食牛血的发生率在不同村庄间差异显著。常见种类中混合餐的发生率在7.1%至27.6%之间，对于马拉若按蚊，在不同村庄间也有显著差异。本研究表明，相距仅几公里的不同村庄之间在宿主选择模式上存在差异，这可能受宿主可获得性影响并具有重要的流行病学后果。
