Abstract
Horn fly, Haematobia irritans (L.), populations in northeastern Mexico were surveyed for resistance to fenvalerate and coumaphos. Compared w ith a susceptible strain of horn flies, resistance levels among field populations for the pyrethroid, fenvalerate, ranged from 36 to 199 tim es at the LD(50) level, indicating that horn fly control with pyrethro ids would be unsatisfactory. Resistance to the organophosphate compoun d, coumaphos, was less evident, with flies at only 1 of 5 locations sh elving levels of tolerance that might interfere with adequate control.
