This study represents the first attempt to evaluate the vectorial capacity of Culex pipiens and Aedes albopictus for Bluetongue virus (BTV). The results indicate that the two Italian populations of Cx. pipiens and Ae. albopictus are not susceptible to BTV infection.
Bluetongue disease (BT), caused by Bluetongue virus (BTV), infects wild and domestic ruminants, causing severe economic damage in the cattle and sheep industry. Proven vectors of BTV are biting midges belonging to the Culicoides genus, but other arthropods are considered potential vectors, such as ticks, mosquitoes, wingless flies, and sand flies. The present study represents the first attempt to evaluate the vectorial capacity of Culex pipiens and Aedes albopictus for BTV. Mosquitoes were artificially fed with blood containing BTV serotype 1. Infection, dissemination and transmission rates were evaluated at 0, 3, 7, 14 and 21 days after an infected blood meal. Viral RNA was only detected up to 3 days post infection in the bodies of both species. This study indicates that the two Italian populations of Cx. pipiens and Ae. albopictus are not susceptible to BTV infection.
