Horn flies, Haematobia irritans (Linnaeus), controlled for 2 yr with 8% fenvalerate cattle ear tags were difficult to control in the third year (1981) at the Univerrsity of Georgia Alapaha Experimental Range (AER). Field data showed progressively poorer control over a 4-yr period which stabilized in the fifth year (1983). Very poor horn fly control was realized with 71/2% flucythrinate (another pyrethroid) cattle ear tags when used for the first time in 1983 at AER. Flucythrinate tags gave very good horn fly control at two other sites in 1983 where pyrethroid used had been limited. Suspected flucythrinate-fenvalerate cross resitance and direct resistance to fenvalerate with resistance ratios of 35 and ca. 40, respectively, were confirmed in several laboratory tests. Rapid selection of resistant horn flies with pyrethroid ear tags and resistance management are discussed. |
