Mosquito numbers in 2005

Together with R.J. Beck of the Tippecanoe County Health Department and one intern, 180 visits were made to habitats that supported mosquito larvae or were suspected of supporting them.  The rainfall pattern and limited amounts of rain per rainfall event in the Lafayette area resulted in relatively few mosquitoes. In contrast to 2003 and 2004, we experienced no extensive floodwater habitats that supported development of larvae of Aedes and Psorophora mosquitoes. The major watersheds (Wabash River and Wildcat Creek) did not flood and rainwater that collected in catch basins and soil depressions tended to dry up before Aedes and Psorophora eggs hatched or larval development was completed.  Habitats that supported the development of Culex larvae in previous years tended to remain dry or didn't support larvae throughout most of the summer.
