^aZero mosquito pools tested positive
^bPositive integer is number of mosquito pools which tested positive
^cMosquito species was not submitted for testing
^dMosquito pool was submitted as Cx. pipiens-restuans but later determined by molecular analysis to be Cx. salinarius
^eTesting positive in 1994 and 1996 were Culex pipiens-restuans and Culex not identified to species level
^fTrapping was not conducted in this county in this year
