Interpretive Summary: Stable flies appeared to transmit West Nile virus (WNV) between pelicans at the Medicine Lake Wildlife Refuge in northeastern Montana, but their ability to transmit the disease was unknown. To study transmission, we inoculated stable flies in the laboratory with WNV. Our study showed that WNV is not biologically transmissible in stable flies, but WNV mechanical transmission is a possibility, especially within bird colonies and among closely spaced livestock.

Technical Abstract: Stable flies, which are notorious pests of cattle and other livestock, were suspected of transmitting West Nile virus (WNV) among American white pelicans at the Medicine Lake Wildlife Refuge in northeastern Montana in 2006-2007. However the ability of stable flies to transmit the virus was unknown. Therefore, USDA-CMAVE scientists worked cooperatively with CDC scientists to determine the potential for mechanical and/or biological transmission. WNV is not biologically transmissible in stable flies, but WNV mechanical transmission is a possibility, especially within bird colonies and among closely spaced livestock
