Vector competence of selected mosquito species (Diptera: Culicidae) for California strains of northway virus (Bunyaviridae: Bunyavirus)
Journal of Medical Entomology 30 (3), 607-613
Abstract: Selected mosquito species from Central Valley, coastal, and alpine habitats of California were evaluated for their vector competence for Northway (NOR) virus. Culiseta incidens Thomson, Culiseta inornata (Williston), and Anopheles freeborni Aitken were the only competent vectors when fed virus. Aedes sierrensis (Ludlow), as well as alpine snow pool Aedes (i.e., Ae. cataphylla Dyar, Ae. hexodontus Dyar, Ae. increpitus Dyar and Ae. tahoensis Dyar), Ae. melanimon Dyar, Ae. washinoi Lanzaro and Eldridge, Culex erythrothorax Dyar, and Cx. tarsalis Coquillett were highly refractory to peroral infection. Alpine snow pool species were poor vectors even following parenteral infection, but 21-35% of intrathoracically inoculated Ae. sierrensis from several lower elevation localities and 39-46% of parenterally infected Cx. tarsalis were able to transmit NOR virus per os. Perorally infected Cs. inornata transmitted NOR virus vertically to their F₁ adult progeny at a low rate (minimal filial infection rate, 1:248).
