Reduction of Tabanid Populations on Cattle with Sticky Traps Baited with Dry Ice

Abstract

Horse fly populations on cattle were reduced by operation of sticky traps baited with dry ice situated around the periphery of a pasture in which the animals were confined. Fly populations remained relatively low on cattle while traps were in operation, but increased within a few days after trapping was discontinued. Large numbers of flies were collected during the brief trapping periods.
