Host-seeking mosquito abundance at communal and non-communal roost sites. a. Mean number of host-seeking Cx. pipiens collected per trap night from August through September 2010 across (A) two non-communal roost sites and (B) two American robin communal roosts near Takoma Park, MD. Adjusted mosquito abundance estimates for communal roost sites (C) account for the effect hosts have on mosquito trapping efficacy. b. Per capita number of host seeking Culex mosquitoes per night at (A) two non-communal roost sites and (B) two American robin communal roosts near Takoma Park, MD. Adjusted mosquito:host ratio estimates for communal roost sites (C) account for the effect hosts have on mosquito trapping efficacy. Error bars encompass ± 1 SE of the mean.
