evaluation of the vector competence of a native uk mosquito Ochlerotatus detritus aedes detritus for dengue chikungunya and west nile viruses
Parasites & Vectors, 2016Co-Authors: Marcus S C Blagrove, Ken Sherlock, Gail E Chapman, Daniel E Impoinvil, P J Mccall, Jolyon Medlock, Gareth J Lycett, Tom Solomon, Matthew BaylisAbstract:Background To date there has been no evidence of mosquito-borne virus transmission of public health concern in the UK, despite the occurrence of more than 30 species of mosquito, including putative vectors of arboviruses. The saltmarsh mosquito Ochlerotatus detritus [syn. Aedes (Ochlerotatus) detritus] is locally common in parts of the UK where it can be a voracious feeder on people.

Evaluation of the vector competence of a native UK mosquito Ochlerotatus detritus (Aedes detritus) for dengue, chikungunya and West Nile viruses
Parasites & Vectors, 2016Co-Authors: Marcus S C Blagrove, Ken Sherlock, Gail E Chapman, Daniel E Impoinvil, P J Mccall, Jolyon Medlock, Gareth J Lycett, Tom Solomon, Matthew BaylisAbstract:Background To date there has been no evidence of mosquito-borne virus transmission of public health concern in the UK, despite the occurrence of more than 30 species of mosquito, including putative vectors of arboviruses. The saltmarsh mosquito Ochlerotatus detritus [syn. Aedes ( Ochlerotatus ) detritus ] is locally common in parts of the UK where it can be a voracious feeder on people. Methods Here, we assess the competence of O. detritus for three major arboviruses: dengue virus (DENV), chikungunya virus (CHIKV) and West Nile virus (WNV) using adult mosquitoes reared from wild, field-obtained immatures. Results We demonstrate laboratory competence for WNV at 21 °C, with viral RNA detected in the mosquito’s saliva 17 days after oral inoculation. By contrast, there was no evidence of laboratory competence of O. detritus for either DENV or CHIKV. Conclusions To our knowledge, this is the first study to demonstrate competence of a UK mosquito for WNV and confirms that O. detritus may present a potential risk for arbovirus transmission in the UK and that further investigation of its vector role in the wild is required.

evaluation of a temperate climate mosquito Ochlerotatus detritus aedes detritus as a potential vector of japanese encephalitis virus
Medical and Veterinary Entomology, 2015Co-Authors: L Mackenzieimpoinvil, Daniel E Impoinvil, Tom Solomon, Sareen E Galbraith, R J Dillon, Hilary Ranson, Nicholas Johnson, Anthony R Fooks, Matthew BaylisAbstract:The U.K. has not yet experienced a confirmed outbreak of mosquito-borne virus transmission to people or livestock despite numerous autochthonous epizootic and human outbreaks of mosquito-borne diseases on the European mainland. Indeed, whether or not British mosquitoes are competent to transmit arboviruses has not been established. Therefore, the competence of a local (temperate) British mosquito species, Ochlerotatus detritus (=Aedes detritus) (Diptera: Culicidae) for transmission of a member of the genus Flavivirus, Japanese encephalitis virus (JEV) as a model for mosquito-borne virus transmission was assessed. The JEV competence in a laboratory strain of Culex quinquefasciatus (Diptera: Culicidae), a previously incriminated JEV vector, was also evaluated as a positive control. Ochlerotatus detritus adults were reared from field-collected juvenile stages. In oral infection bioassays, adult females developed disseminated infections and were able to transmit virus as determined by the isolation of virus in saliva secretions. When pooled at 7-21days post-infection, 13% and 25% of O.detritus were able to transmit JEV when held at 23 degrees C and 28 degrees C, respectively. Similar results were obtained for C.quinquefasciatus. To our knowledge, this study is the first to demonstrate that a British mosquito species, O.detritus, is a potential vector of an exotic flavivirus.

high morphological and genetic variabilities of Ochlerotatus scapularis a potential vector of filarias and arboviruses
Parasites & Vectors, 2015Co-Authors: Vivian Petersen, Mariana Devicari, Lincoln SuesdekAbstract:Background Ochlerotatus scapularis is a potential vector of filarias and arboviruses in the Neotropics. This species was once typically associated with sylvatic environments; however, cases of synanthropy and urbanization of this species have been increasingly reported in southeast Brazil. Despite the medical relevance of Oc. scapularis, its populational variability is not yet known. To our knowledge, this is the first report describing the morphological and genetic variabilities of this species.
