Container Type Influences the Relative Abundance, Body Size, and Susceptibility of Ochlerotatus triseriatus (Diptera: Culicidae) to la Crosse Virus

摘要: Ochlerotatus triseriatus (Say), the primary vector of La Crosse virus (LAC), develops in a variety natural and artificial aquatic containers where it often co-occurs with larvae other mosquito species. We conducted field study at two woodlots (South Farms Trelease Woods) Urbana, IL, to examine how container type influences abundance, body size, susceptibility LAC. Mosquito pupae were collected from tree holes, plastic bins, waste tires, eclosing adults identified species morphologically. Oc. japonicus (Theobald) females orally challenged LAC midgut infection rate, disseminated titer determined by reverse-transcriptase real-time PCR. was dominant holes while Culex restuans mostly containers. Female bins significantly larger than those or tires. South also Woods. tires more susceptible relative holes. In addition, had higher For each site, wing length not correlated dissemination rates. These findings suggest that which Oc.triseriatus develop may contribute spatial temporal dynamics transmission.
