Effects of Bayofly on specimens of Culicoides species when incubated in hair taken from the feet of previously treated cattle and sheep
Abstract
Sheep and cattle were treated with Bayofly pour-on containing 1 g cyfluthrin per 100 ml ready-to-use solution. Seven, 14, 21 and 28 days after treatment, hair was clipped off from the back and feet and mixed for 10-15 s, 30 s, 1 or 2 min with freshly caught Culicoides midges. It was found that the insecticide on hair from the legs--the predominant biting site of midges--had a significant killing effect on Culicoides for 3-4 weeks, even after a short-term contact.
