Adult horn fly densities were determined at three elevations (800, 1800 and 2400 m) over two years using fly counts on cattle. In 1995, cattle at the 800 m elevation had the highest density of flies. In 1996, the greatest density of flies occurred on cattle at the 1800 m elevation. In both 1995 and 1996, the fewest flies were recorded on cattle at the 2400 m elevation, with densities below 90 flies per side. Based on published economic injury levels, control of horn flies at elevations above 2400 m may not be economically justifiable in Wyoming. Cattle grazed at elevations at or below 1800 m may not have horn fly populations large enough to merit control and therefore should be examined for fly densities before control measures are taken. |
