An experiment to determine if wild Culex nigripalpus preferentially enter l
ard-can traps baited with chickens or bobwhite quail was conducted. A stron
g preference for the chicken-baited trap was observed. Further development
of transmission models for St. Louis encephalitis virus in southern Florida
should consider increased biting rates on sentinel chickens and the conseq
uences for the interpretation of sentinel seroconversion data.
