Abstract:Power dusting of shorn sheep in spring with 1% coumaphos eradicated infestations of Melophagus ovinus (L.) at our recommended application rates of 2.5–3 lb/min. Generally, high reductions but not eradication were provided by coumaphos 0.5%, crotoxyphos 3%, stirofos 3 and 5%, and phosmet 1%. Ronnel 1% applied below recommended rates did not eradicate infestations. Shearing sheep before lambing reduced populations of sheep keds an average 77% compared with the populations on flocks sheared after lambing.
