Aedes Taeniorhynchus Vectorial Capacity Informs A Pre-Emptive Assessment Of West Nile Virus Establishment In Galápagos

Abstract: Increased connectivity with the mainland has led to the arrival of many invasive species to the Galápagos Islands, including novel pathogens, threatening the archipelago's unique fauna. Here we consider the potential role of the mosquito Aedes taeniorhynchus in maintaining the flavivirus West Nile virus [WNV] should it reach the islands. We report on three components of vectorial capacity - vector competency, distributional abundance and host-feeding. In contrast to USA strains, Galápagos A. taeniorhynchus is … Show more

“…() also report distributions of C. quinquefasciatus and A . taeniorhynchus on Isabela and Santa Cruz in 2012–2014, consistent with our current and earlier studies (Bataille et al ., , , , ; Eastwood et al ., ). The relative roles of human‐mediated transport, natural dispersal and local adaptation in the speed of establishment across the islands remain to be fully understood and are difficult to quantify due to a lack of historical monitoring for the presence of this mosquito.…”

“…prior to the rainy season commencing in January (and also prior to the abundance peak of the endemic mosquito species A. taeniorhynchus ; Eastwood et al ., ). This might be counterintuitive, since mosquito abundance might be expected to increase with precipitation, as it does for A. taeniorhynchus (Galardo et al ., ; Eastwood et al ., ). However, drought conditions elsewhere have been associated with increased number of blood‐fed Culex spp.…”

“…Specifically, typical epizootic VEEV strains of the subtypes IAB and IC are efficiently transmitted by this mosquito (Weaver et al, 2004). Additionally, this insect has also been identified as a competent vector of other arboviruses such as the Saint Louis encephalitis virus (Nayar et al, 1986), Eastern equine encephalitis virus (Ortiz et al, 2003), and West Nile virus (Eastwood et al, 2013). Furthermore, O. taeniorhynchus plays a major role in the transmission of the dog heartworm (Dirofilaria immitis) in South and Central America (Manrique-Saide et al, 2010).…”
