Field Test of Pyrethroid Ear Tags. Sprays. and a Pour-on Formulation for Control of Horse Flies' on Cattle
نویسندگان
چکیده
Ten insecticide formulations. including five ear tags containing pyrethroids, were tested against field populations of Tabanus abactor Philip. The most effective insecticide was the 1.0% pcrmethrin pour-on which caused greater than 55% mortality of exposed specimens through 2 weeks. The 10% permcthrin ear tag produced 79 and 55% mortality of T. abaclor 2 and 3 weeks after application, respectively. No other insecticide, including ear tags conLnining fenvalerate, nucythrinate or cypcrmethrin caused grcaler than 36% mOfllllity during any treatment period. None of the insecticides prevented this species from biting and taking a blood meal.

Three studies were conducted to evaluate the effectiveness of insecticide-impregnated ear tags in controlling face flies, Musca autumnalis DeGeer, and horn flies, Haematobia irritans (Linn.), on pastured beef cattle. In one 16-week trial, polyvinyl chloride (PVC) ear tags treated with stirofos (Rabon) insecticide reduced horn fly numbers by 79% (P less than .05) and face fly numbers by 30% (P l...
