Aedes vittatus in Spain: current distribution, barcoding characterization and potential role as a vector of human diseases

Aedes vittatus is currently found in Africa, Asia and Europe, where it acts as a vector of pathogens causing animal and human diseases. Like other Aedes species, Ae. vittatus is able to breed in artificial containers. The European Centre for Disease Prevention and Control has recently highlighted the need for molecular tools (i.e. barcoding characterization) that enable Aedes species to be identified in entomological surveys. Mosquito larvae and adults were sampled in southern Spain using molecular approach to amplify and sequence a fragment of the cytochrome c oxidase subunit 1 gene (barcoding region) of the mosquitoes. The blast comparison of the mosquito sequences isolated from Spain with those deposited in public databases provided a ? 99% similarity with sequences for two Aedes mosquitoes, Ae. vittatus and Ae. cogilli, while similarities with other Aedes species were ? 94%. Aedes cogilli is only present in India and there are no records of this species from Europe. Due to the low genetic differences between Ae. vittatus and Ae. cogilli, the barcoding region should not be used as the only method for identifying Ae. vittatus, especially in areas where both of these Aedes species are present. This type of analysis should thus be combined with morphological identification using available keys and/or the characterization of other molecular markers. In addition, further entomological surveys should be conducted in order to identify the fine-scale distribution of this mosquito species in Europe. informacion[at]ebd.csic.es Alazne Díez-Fernández et al (2018) Aedes vittatus in Spain: current distribution, barcoding characterization and potential role as a vector of human diseases.

First molecular identification of the vertebrate hosts of Culicoides imicola in Europe

Culicoides (Diptera: Ceratopogonidae) are vectors of pathogens that affect wildlife, livestock and, occasionally, humans. Culicoides imicola (Kieffer, 1913) is considered to be the main vector of...

Powerful tools to improve studies of feather mites

Feather mites are among the most abundant and commonly occurring bird ectosymbionts. Basic questions on the ecology and evolution of feather mites remain unanswered because feather mite species...
