The Release Of Insects Sterilized By Colbalt 60 To Control A Wild Population Of Stable Flies At The Sdsu Beef Cattle And Sheep Nutrition Unit In Brookings, Emmert R. Easton, Michael A. Catangui

South Dakota Beef Report, 1986

Sterile stable flies were released weekly a t the SDSU Beef Cattle and Sheep Nutrition Unit at Brookings from July 24 through September during the summer 1986 season t o eliminate wild populations of insects. Flies that were sterilized were marked with a dye so when recaptured by an insect net or a sticky trap they could be differentiated from wild, normal or fertile flies. A trend toward reduced f l y numbers was observed 3 weeks following the first release. A 1:5 ratio of sterile to wild flies was achieved in 6 weeks.

The Fly Buster. A Combination Mineral Feeder/Spray Device For The Control Of The Horn Fly And The Face Fly On Pastured Cattle, Emmert R. Easton

South Dakota Beef Report, 1986

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 ...
