Horn flies are bloodsucking insects that can be seen on the backs and sides of beef and dairy cattle during most of the summer. For the best experience on our site, be sure to turn on Javascript in your browser. If cattle are reluctant to enter the trap, it may be necessary to remove most or all of the canvas strips, and then to replace them one at a time after the cattle overcome their shyness. 2014; 97(7):4624-31 (ISSN: 1525-3198) Denning SS; Washburn SP; Watson DW Up and Down arrows will open main level menus and toggle through sub tier links. Tab will move on to the next part of the site rather than go through menu items. The development of insecticide resistant horn flies in some areas, plus interest in non-chemical fly control, spurred reinvestigation of fly traps. Rather than emerging as adults, they overwinter (diapause). Extension   /   Bruce’s simple design is now known as the Bruce walk-thru fly trap, and different versions have been studied for horn fly control in various parts of the country. Now, applicating devices, such as cable backrubbers and dust bags, are popular for horn fly control because they require little labor on the behalf of humans. A fly trap structure won't provide complete control, but research by the University of Missouri showed it could take fly numbers below the economic threshold of … As with dust bags and back rubbers, placement of fly traps is important. Horn flies die naturally after a short time off of the animal. Walk-Through Trap to Control Horn Flies on Cattle. As cattle pass through the trap, strips of canvas or old carpet dislodge flies from the animals. Figure 6 A cutaway view of the horn fly trap shows how the trapping elements are placed along its side. The flies move through the angled side slats to light and are trapped between the slats and the outer screened sides of the trap. The sides support panels bearing electric grates, which grates are accessible to flying insects on both the inside and outside of the trap. Walk-through fly traps. Pathways to water, feed, or mineral supplements are ideal. University of Kentucky research has shown differences in the range of 12 pounds per head resulting from horn fly control. After a time, which varies depending on temperature, the eggs hatch, and maggots develop in the dung. 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. These strips dislodge most of the horn flies on the animals' backs and sides. On some evaluation dates, reductions were as high as 90%. Corn or other feed can be used as bait to draw cattle into the trap. Departments & Units   /   This will reduce damage to trap screening and framework. When these systems are charged with effective insecticide and properly situated, the cattle treat themselves. Similar results were obtained by David L. Lindell, regional extension specialist, during 1994-95, when field trials with two horn fly traps during the latter season averaged 40 percent control. Published on: 3/8/2018 Author/s : Cecilia Miraballes 1, Diego Buscio 2, André Diaz 2, Javier Sanchez 3, Franklin Riet-Correa 1, Anderson Saravia 1, Eleonor Castro-Janer 2. Horn fly eggs are small, reddish-brown and generally laid in clumps on grass and other vegetation covered by the cow pat. By 1986 the problem of horn fly resistance to pyrethroids was widespread enough in Missouri to warrant re-evaluation of Bruce's trap design. These are non-toxic or non-pesticide pasture fly traps for horn, horse, deer and stable flies. Horn flies congregate on the backs of cattle, often clustering on the midline and spreading down the sides. Twice daily use of a vacuum-powered, walk-through fly trap kept horn fly populations below a threshold of 200 flies per animal without the use of insecticides. Horn fly control on nearby herds wearing insecticide impregnated ear tags averaged 88% to 98% during the tests. Bruce's trap is a walk-through system. Dean For the best experience on our site, be sure to turn on Javascript in your browser. When building a trap, remember that lumber that is pressure-treated to resist rot will outlast untreated wood and does not require painting.

Some buffalo fly trap designs can remove up to 90 per cent of the flies from the cattle as they walk through the … This feeding activity is painful and annoying to cattle. Soon after Bruce completed his experiments, however, the United States became involved in World War II, and few people were thinking about horn fly control. A 1930’s vintage walk-through fly trap is providing fly relief for cattle on Linda Simmons’ South Dakota ranch. Dr. Subba Reddy PalliDepartment Chair & State EntomologistS-225 Agricultural Science Center NorthLexington, KY 40546-0091859.257.7450entchair@uky.edu, UK Entomology: Vision, Mission, & Core Values, Nancy Cox, Ph.D. They should be located where the animals must pass through then regularly. Ask for plan 1-904-C-6, “Fly Trap”. Digital Media Library, Images: University of Kentucky Entomology, College of Agriculture, Food and Environment. It traps flies between the exterior screen on one side and the zigzag screen on the other. Electric Walk-Through Fly Trap for the control of Face, Stable, and Horn Flies OVERVIEW Horn, stable and face flies pose a complex and expensive pest problem for cattle ranchers. Cattle producers dissatisfied with the performance of insecticidal ear tags requested information about alternative control methods. Just make a wrap around the barrel and overlap the ends a little to stick the paper back to itself. They use a tubular mouthpart to pierce the skin and get a blood meal. Enter and space open menus and escape closes them as well. Bruce spent the rest of his career working with pesticides and studying their use for horn fly control. He experimented with several designs, perfected one and deposited schematic drawings and an explanation of his trap with the National Agricultural Library in Maryland. Dairy Cattle / Technical articles / Management. When mature, the maggots pupate in or below the pat, and later, emerging adults disperse to seek cattle hosts. and you can get a PDF of blueprints for the trap. Development of a novel walk-through fly trap for the control of horn flies and other pests on pastured dairy cows. Irritation and feeding by horn flies, especially on yearling cattle, results in reduced weight gain during horn fly season. A walk-through trap designed to collect horn fly adults from cattle can also lower populations. Meyer Department of Entomology, North Dakota State University R.D. The animal exits the trap with fewer flies on it, and the trapped flies cannot escape. University of Kentucky College of Agriculture Insecticide-impregnated cattle ear tags release small amounts of an insecticide which are distributed over the animal during grooming or rubbing. The development of insecticide resistant horn flies in some areas, plus interest in non-chemical fly control, spurred reinvestigation of fly traps. Cattle enter through either end, pass through the 10-foot trap and contact a series of strips made of canvas or old carpet. Screened elements along both sides of the device functioned as cone traps, thereby catching horn flies, Haematobia irritans (L.), as they were swept from cattle by strips of carpet hung from the roof. University of Missouri Extension is an equal opportunity/access/affirmative action/pro-disabled and veteran employer. ENTFACT-508: Walk Through Horn Fly Trap for Pastured Cattle  |  Download PDF. The horn fly, Haematobia irritans (Linnaeus), was introduced into the United States more than a century ago. Please check with your local county agent or regulatory official before using any pesticide mentioned in this publication. This level of control was less than that afforded by insecticidal ear tags and some other treatments but maintained horn flies below the injury level of about 200 flies per animal. Research   /   The EPPS Biting Fly Trap requires no electricity, chemicals, or messy baits; it uses liquid soap and water to trap and kill biting flies, horse flies, deer flies, and many more. The top is made from plywood. Measuring about 10 feet in length, the walk-through fly trap is constructed with a solid top and partially solid sides to create a dim interior. Cattle pass through the trap to get water. Animals using the trap had an average of 50% to 70% fewer horn flies during Missouri field trials than untreated animals. Of course, ALWAYS READ AND FOLLOW LABEL DIRECTIONS FOR SAFE USE OF ANY PESTICIDE!

The frame is made from standard-sized CCA treated lumber, and the end framing is extended laterally to provide stability. The number of flies removed from the cattle represented the on-animal and on-farm population. A zigzag screening in the trapping elements functions as the cone (Figure 2). This plan provides construction details to build a walk through fly trap for cattle. Experiments will be designed to demonstrate pasture fly control before and after fly populations have established and thresholds had been exceeded. It may be necessary to wash the element screens clear with water if they become clogged with mud and debris. A prototype walk-through fly vacuum system, designed to remove horn flies Haematobia irritans (L.) (Diptera: Muscidae) from cattle, was developed and … Because flies are attracted to light, they travel toward the screened sides of the trap. While the trap caught some face flies, it did not result in any effective reduction in fly numbers per head. One effective method is the Epps Biting Fly Trap™, invented by an Oklahoma cattleman and marketed by Horseline Products in Henderson, TN. The trap reduces the numbers of flies on the animals as they move through it. There, the screening on the exterior of the trapping element interrupts the flies' progress. Because flies are attracted to light, they travel toward the screened sides of the trap. 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). Reports of these tests can be obtained from him at Courthouse, Room 16, 100 W. Franklin, Clinton, Mo. By 1986 resistance was reported as far north as the Canadian border.

The study was conducted during 4 fly seasons over 17 consecutive weeks each year within the months of May through September at 1 dairy research herd in the coastal plain of North Carolina. (Figure 6 has a cutaway view of the trap.) The canvas strips have been removed for clarity. The horn fly, Haematobia irritans (Linnaeus), was introduced into the United States more than a century ago. Although many systemic insecticides show an effect against horn flies, most (such as ivermectin) are too costly for the frequent reapplications required. Cattle passed freely through the trap, leaving behind many of the horn flies that were on them. As cattle walk through the device, the flies are brushed off of them. While horn flies take only small quantities at a time, they feed frequently throughout the day. Ideally, the tunnel-like trap should be placed where animals can pass through it several times a day. The best site for placement of the trap is between pasture and the source of water. After the flies feed and mate, the female is ready to deposit eggs. Holes punched through the small end of the triangle permit the flies to crawl toward the outside of the trap (Figure 3). The triangular shape formed by the bending of the screen makes alternate large ends that face the interior of the trap and small ends that face the outside of the trap. The only other maintenance required is periodic inspection and repair of the trap as needed. A sharp knife will cut through it to throw it away.” Kevin says that he caught face flies, horse flies and deer flies. You can get most of the materials easily from lumberyards, farm supplies or hardware stores. Figure 4 In this completed horn fly trap, heavy wire panels funnel cattle through the trap.

The chickens would eat every fly they could reach on the paper. I just started wrapping over the old paper with the new. A walk-through fly trap for cattle and similar livestock is provided with a steel tubular frame on which is provided a roof and sides of pressure treated lumber. The flies become trapped in the screened areas. 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). The idea of a walk through fly trap to protect cattle from horn flies was first presented in 1899 with some additional work in 1930. These flies spend virtually all of their time on animals. A walk-through fly trap designed in 1938 by W. G. Bruce was tested for two field seasons in Missouri. These tags generally employ pyrethroid insecticides and, until recently, gave almost complete control of horn flies for a summer season. 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. This fact sheet presents general information on the trap and research results from field tests at the University of Missouri. A walk-through fly trap for cattle and similar livestock is provided with a steel tubular frame on which is provided a roof and sides of pressure treated lumber.

These strips dislodge most of the horn flies on the animals' backs and sides. Flies are attracted to the large dark trap because it appears to be a potential host. Cattle enter through either end, pass through the 10­foot trap and contact a series of strips made of canvas or old carpet. The trap itself is placed in a fence line with a watering pond on one side. The trap requires no chemicals, no labour and has the unexpected design feature that ants quickly take up residence to take care of all of the cleaning. Dead flies that accumulate in the trap can be removed but scavenger insects will do an effective cleanup job if the trap is not cleaned. Efficiency of a walk-through fly trap for Haematobia irritans control in milking cows in Uruguay . Biting flies (horseflies, deerflies, stable flies, black flies, mosquitoes, etc.) The animal exits the trap with fewer flies on it, and the trapped flies cannot escape. Putting mineral in an enclosure with entry through the trap is an effective technique.
