ABSTRACT Host utilization patterns of female mosquitoes, and WNV infection rates in male and female mosquitoes, were examined in East Baton Rouge Parish to identify potential vectors of West Nile virus (WNV). A total of 244,374 female mosquitoes were collected between November 2002 and October 2004 and tested by viral isolation. Additionally, 131,896 female mosquitoes were tested by VecTest in 2003, and 167,175 female mosquitoes were tested by RT-PCR in 2004. West Nile virus was isolated from 17 of 36 mosquito species assayed by virus isolation, WNV antigens were detected in 9 of 27 species tested by VecTest, and WNV …

A three year study was conducted to determine if testing mosquitoes collected in modified sentinel chicken boxes for West Nile Virus (WNV) or testing sentinel chickens for WNV antibody would detect WNV activity prior to reports of human cases in East Baton Rouge (EBR) Parish, Louisiana. In one year we also compared the effectiveness of CDC light traps, gravid traps, and sentinel chicken box traps for collecting WNV positive mosquitoes. In all three years, we detected WNV activity in mosquito collections from sentinel chicken box traps prior to the onset of human cases, while there were no seroconversions in the …
