Aedes caspius is a vector of Rift Valley fever, Sindbis, Tahyna and West Nile viruses, transmits microfilariae of Dirofilaria immitis and D. repens in Europe, is an efficient vector of the tularaemia bacterium Francisella tularensis in Russia and the causal agent (poxvirus) of myxomatosis ( Gad et al. 1987 ; Schaffner et al. 2001 ; Gratz 2004a ; Trari et al. 2017 ; Ferreira et al. 2015 ). In southern Spain , this species has been found infected with avian Plasmodium ( Ferraguti et al. 2013 ) .
