The sides support panels bearing electric grates, which grates are accessible to flying insects on both the inside and outside of the trap. “Prior to the installation of the trap in 2007, the cattle routinely had horn fly populations above 1,000 flies per animal and would require insecticide applications for horn fly control. Dairy Cattle / Technical articles / Management. Lexington, KY 40546-0091 The number of flies removed from the cattle represented the on-animal and on-farm population. Although the trap design incorporates clean-out doors at the bottom of each trapping element, scavenger insects soon inhabit the trapping elements and eat the dead flies (Figure 5). As horn flies spend the majority of time during the summer on the backs and sides of cattle this trap helps reduce their numbers. In this respect, placement is like that for dust bags and backrubbers.

Because the cone now faces the wrong way for the insects — that is, the small end faces them — it is unlikely that many will find the holes and escape. It traps flies between the exterior screen on one side and the zigzag screen on the other. The development of insecticide resistant horn flies in some areas, plus interest in non-chemical fly control, spurred reinvestigation of fly traps. The animal exits the trap with fewer flies on it, and the trapped flies cannot escape. Left and right arrows move across top level links and expand / close menus in sub levels.

Very small numbers of stable flies and horse flies were caught in the traps but the traps do not provide effective control of these species. The trap reduces the numbers of flies on the animals as they move through it. This fact sheet presents general information on the trap and research results from field tests at the University of Missouri. Rather than emerging as adults, they overwinter (diapause). are attracted to large, dark objects such as the shape and silhouette of an animal, so the trap is a framework with a large dark portion and some transparent panels. The horn fly, Haematobia irritans (Linnaeus), was introduced into the United States more than a century ago.

Researchers paid little attention to walk-through fly traps, however, until Clyde Morgan and Gus Thomas of the USDA noticed Bruce's paper during the 1970s while they compiled a complete bibliography on the horn fly. Three trapping elements along each side of the trap catch flies by the "inverted cone" principle, similar to a minnow trap, upon which many insect traps depend (Figure 1). A prototype walk-through fly vacuum system, designed to remove horn flies Haematobia irritans (L.) (Diptera: Muscidae) from cattle, was developed and tested for efficacy. When these systems are charged with effective insecticide and properly situated, the cattle treat themselves. Efficiency of a walk-through fly trap for Haematobia irritans control in milking cows in Uruguay .
