TL;DR: There are two dose-dependent barriers to the transmission of western equine encephalomyelitis virus in infected female Culex tarsalis and the distribution of virus in the tissues of nontransmitting females with either of these barriers is described.

TL;DR: The extrinsic incubation rate (inverse of the time in days from infection to median transmission) of western equine encephalomyelitis and St. Louis encephalitis viruses by laboratory strains of Culex tarsalis Coquillett increased as a linear function of incubation temperatures from 10 to 30 degrees C, and midgut escape and salivary gland infection barriers limited the transmission rates of SLE virus at all temperatures.

TL;DR: This is the first report of an inverse relationship between temperature of extrinsic incubation within the range of 25 degrees-32 degrees C and vector competence of a mosquito for an arbovirus.

TL;DR: St. Louis encephalitis (SLE) virus has become established in the Los Angeles Basin of California, where it most likely is maintained by horizontal transmission among Culex tarsalis Coquillet and passerine birds in park-riparian habitat.

TL;DR: Female Aedes albopictus and Aedes epactius infected by inoculation with St. Louis encephalitis (SLE) virus transmitted virus transovarially to their F1 progeny, and transovarial transmission of SLE virus was not demonstrated with colonized strains of Aedes dorsalis, Ades sierrensis, Aded triseriatus, Ade vexans, and field strains of Ae.
