horn fly, face fly, mineral feeder/spray device, control
A combination mineral feeder/spray device was evaluated as a different approach for the suppression of horn and face flies under range conditions in east central South Dakota during the 1985 season. Ravap, Ectrin and Ciovap were applied at the rates of 1.25. .05 and 1.0%, respectively, to Black Angus cattle in three separate pastures with the spray device containing Morton's Farm and Ranch T-M and salt containing iodine and other trace minerals. Cattle in a fourth pasture that were not treated were used as the control. A canister containing Freon 12 acts as a propellant to force the insecticide under pressure out of a nozzle that produces an aerosol spray over the cattle. A 3-way bulb valve linked to a face flap permits cattle to treat themselves when the animal pushes the flap inward. The entire device is on a swivel so that it turns easily and lessens the possibility of being damaged over time by a large herd of animals. Ciovap provided excellent control for both face flies (94.9%) and horn flies (91.2%), while control was less effective with Ectrin (62.0% for the face fly and 75.01% for the horn fly ) . Face fly control was least effective with Ravap (42.5%), while horn fly reduction was 81.4%. Beef cattle in this experiment were observed to use the device routinely, but the effectiveness in fly control in the herd diminishes when the salt/mineral in the holding container has been depleted.
