A statewide survey was made to determine the resistance to dimethoate and ronnel of house flies, Musca domestica L., collected from poultry or dairy farms at 32 locations throughout the state of Florida. Compared to flies from the susceptible Orlando strain, flies from dairies were 4.9 to 21.2-fold more resistant to ronnel, and flies from poultry farms were 3.8 to 54.5-fold more resistant. Also, fly strains from dairies were 3.4 to 31.0-fold more resistant to dimethoate than flies from the Orlando strain, and fly strains from poultry farms were 1.8 to 28.5-fold more resistant.
