76 - Culex Soup in the Northern Suburbs of Chicago, IL: Hunting down their cryptic habitats

The Northern Suburbs of Chicago, IL has consistently been a hot spot for West Nile virus (WNv) since its introduction in 2001.  There are several reasons why this area consistently has WNv in its mosquito population and sees spill over into the human population.  First, we have a menagerie of Culex species and hybrids which are all competent vectors for WNv.  Second, we have diverse above ground habitat for these species to flourish, and lastly, we must consider the ground below our feet – the extensive stormwater sewer system in the area.  These subterranean cryptic habitats can serve as oviposition sites, larval development, and make excellent hibernacula for overwintering Culex species mosquitoes.  I will be discussing the extent of the cryptic habitats above and below ground and the challenges we face in elucidating the role they may play in the endemic West Nile virus in the area.
