    La Crosse Virus in Aedes japonicus japonicus Mosquitoes in the Appalachian Region, United States
    Harris, M. Camille; Dotseth, Eric J.; Jackson, Bryan T.; Zink, Steven D.; Marek, Paul E.; Kramer, Laura D.; Paulson, Sally L.; Hawley, Dana M. (2015-04)
    La Crosse virus (LACV), a leading cause of arboviral encephalitis in children in the United States, is emerging in Appalachia. For local arboviral surveillance, mosquitoes were tested. LACV RNA was detected and isolated from Aedes japonicus mosquitoes. These invasive mosquitoes may significantly affect LACV range expansion and dynamics.

    La Crosse Virus Infection Alters Blood Feeding Behavior in Aedes triseriatus and Aedes albopictus (Diptera: Culicidae)
    Jackson, Bryan T.; Brewster, Carlyle C.; Paulson, Sally L. (Oxford University Press, 2012-12-01)
    The effects of La Crosse virus (LACV) infection on blood feeding behavior in Aedes triseriatus (Say) and Aedes albopictus (Skuse) were investigated in the laboratory by measuring the size of the bloodmeal imbibed and the extent of refeeding by virus-infected and uninfected mosquitoes. LACV-infected Ae. triseriatus and Ae. albopictus took significantly less blood compared with uninfected mosquitoes. Twice as many virus-infected Ae. triseriatus mosquitoes refed compared with uninfected individuals (18 vs. 9%; P < 0.05); however, virus infection had no significant effect on the refeeding rate of Ae. albopictus. Reduction in bloodmeal size followed by an increased avidity for refeeding may lead to enhanced horizontal transmission of the LACV by its principal vector, Ae. triseriatus.
