Tm. Gilliland et al., ARBOVIRUS SURVEILLANCE IN IOWA, USA, DURING THE FLOOD OF 1993, Journal of the American Mosquito Control Association, 11(2), 1995, pp. 157-161
During the summer of 1993, mosquitoes were collected by dry ice-baited
CDC light traps from July through September in 12 different cities in
Iowa. In all, 169,907 mosquitoes belonging to 17 different species we
re collected. A total of 2,013 pools were processed for arbovirus isol
ation, from which 59 arbovirus isolates were obtained: 41 Flanders (FL
A), 16 trivittatus (TVT), one Cache Valley (CV), and one Turlock (TUR)
. Supplementary sentinel chicken and human data are also included. In
spite of the increase in larval habitats and elevated mosquito populat
ions, there was not an increase in virus transmission.
