Incursion and establishment of the Old World arbovirus vector Aedes (Fredwardsius) vittatus (Bigot, 1861) in the Americas.

Incursion and establishment of the Old World arbovirus vector Aedes (Fredwardsius) vittatus (Bigot, 1861) in the Americas. Acta Trop. 2020 Nov 04;:105739 Authors: Pagac BB, Spring AR, Stawicki JR, Dinh TL, Lura T, Kavanaugh MD, Pecor DB, Justi SA, Linton YM Abstract Routine biosurveillance efforts at the Naval Station Guantanamo Bay, Cuba, on 18 June 2019, detected two unusual mosquitos in a CO2-baited CDC light trap. Morphological and molecular analysis confirmed the presence of Aedes (Fredwardsius) vittatus (Bigot, 1861) - the first record of the Old World dengue, chikungunya, Zika and yellow fever virus vector into the Americas - and provide evidence for its establishment in Cuba. Newly submitted GenBank sequences from Dominican Republic further evidence its establishment in the Caribbean, and a median-joining network analysis using mitochondrial COI gene sequences clearly supports multiple introductions of Ae. vittatus into the Caribbean from the Indian subcontinent. Many Ae. vittatus COI barcode sequences in GenBank are misidentified as Aedes (Fredwardsius) cogilli Edwards, 1922. PMID: 33159899 [PubMed - as supplied by publisher]
