Abstract

To evaluate the role of Culex mosquitoes as enzootic and epidemic vectors for WNV, we identified the source of vertebrate blood by polymerase chain reaction amplification and sequencing portions of the cytochrome b gene of mitochondrial DNA. All Cx. restuans and 93% of Cx. pipiens acquired blood from avian hosts; Cx. salinarius fed frequently on both mammals (53%) and birds (36%). Mixed-blood meals were detected in 11% and 4% of Cx. salinarius and Cx. pipiens, respectively. American robin was the most common source of vertebrate blood for Cx. pipiens (38%) and Cx. restuans (37%). American crow represented <1% of the blood meals in Cx. pipiens and none in Cx. restuans. Human-derived blood meals were identified from 2 Cx. salinarius and 1 Cx. pipiens. Results suggest that Cx. salinarius is an important bridge vector to humans, while Cx. pipiens and Cx. restuans are more efficient enzootic vectors in the northeastern United States.

  • Primary WNV vectors display generalist host preferences, feeding on multiple host species.

    “primary WNV vectors display generalist host preferences, feeding on multiple host species (Tempelis 1975; Molaei et al. 2006)”

    From Avian host community structure and prevalence of West Nile virus in Chicago, Illinois (2009) · cites this paper as Molaei et al. 2006

    The Discussion reports that the principal vectors feed on multiple host species: Cx. pipiens and Cx. restuans feed on several bird species, while Cx. salinarius feeds on birds and mammals. But it describes Cx. salinarius as more opportunistic than the other two and Cx. restuans as exclusively bird-feeding in this study, so it does not support calling all three generalists.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
