While horn flies take only small quantities at a time, they feed frequently throughout the day. Development of a novel walk-through fly trap for the control of horn flies and other pests on pastured dairy cows. Some buffalo fly trap designs can remove up to 90 per cent of the flies from the cattle as they walk through the … (Figure 6 has a cutaway view of the trap.) The Cow-Vac is … 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. Horn flies die naturally after a short time off of the animal. Repeated use of the trap can reduce the overall local population of horn flies. When these systems are charged with effective insecticide and properly situated, the cattle treat themselves. It traps flies between the exterior screen on one side and the zigzag screen on the other. Cultural methods:Remove and properly dispose of fresh manure from barns and stalls to interrupt the horn fly’s life cycle and help prevent new populations from developing. By 1986 resistance was reported as far north as the Canadian border. 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. Sometimes, horn flies settle around the bases of horns, and when the weather is hot, they may move onto the belly. The trap functions somewhat like a minnow trap. Departments & Units   /   Figure 6 A cutaway view of the horn fly trap shows how the trapping elements are placed along its side. The chickens would eat every fly they could reach on the paper. The flies crawl through these holes and cannot find their way back out. Participating farmers will be interviewed in the first project year as to the predominant fly problems facing the producers. Philanthropy & Alumni Non-chemical Horn Fly Traps H.J. Insecticide-impregnated ear tags are popular for controlling horn flies on cattle. Horn flies congregate on the backs of cattle, often clustering on the midline and spreading down the sides. Wear and tear was low in field tests so a trap should last for several seasons. 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. … 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. View all agriculture and environment programs, Starting a Small Business: The First Steps, Agricultural systems and natural resources, Agricultural Business and Policy Extension, Veterinary Extension and Continuing Education, Exceed - Regional Economic and Entrepreneurial Development, Mid-America Trade Adjustment Assistance Center, Missouri Procurement Technical Assistance Centers, Missouri Small Business Development Centers, Continuing Medical Education and Physician Lifelong Learning, Tai Chi for Arthritis and Falls Prevention, equal opportunity/access/affirmative action/pro-disabled and veteran employer. Horn fly control on nearby herds wearing insecticide impregnated ear tags averaged 88% to 98% during the tests. Biting flies (horseflies, deerflies, stable flies, black flies, mosquitoes, etc.) Insecticide treatments are used to help keep stable flies off animals, but treatments wash off as cattle walk through wet grass or wade through water. 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. Although most cattle can tolerate up to 200 horn flies without showing economic losses, larger numbers of these flies decrease cattle weight gain and milk output. These strips dislodge most of the horn flies on the animals' backs and sides. Horn fly eggs are small, reddish-brown and generally laid in clumps on grass and other vegetation covered by the cow pat. One effective method is the Epps Biting Fly Trap™, invented by an Oklahoma cattleman and marketed by Horseline Products in Henderson, TN. Research   /   64735. The canvas curtains inside the trap have been removed in this photograph. There, the screening on the exterior of the trapping element interrupts the flies' progress. You can often use fence line to route cattle through the trap, and you can easily move electric fencing. Another green way to get rid of flies is with a walk-through fly trap. Dairy Cattle / Technical articles / Management. 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. Tab will move on to the next part of the site rather than go through menu items. The flies move through the angled side slats to light and are trapped between the slats and the outer screened sides of the trap. How the trap works Bruce's trap is walk-through system. Figure 5 The elements can be cleaned while on the trap or can be removed for convenience. Putting mineral in an enclosure with entry through the trap is an effective technique.

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. Implement a pasture fly control strategy for participating milking herds using the walk through fly-trap. You can use standard-sized lumber, screening and other items where possible. Corn or other feed can be used as bait to draw cattle into the trap. Additional data on horn flies, as well as face … The sides support panels bearing electric grates, which grates are accessible to flying insects on both the inside and outside of the trap. In general, ear tags have provided excellent, long term control of horn flies and a reduction in face fly numbers. This activity occurs frequently during early morning. Cattle enter through either end, pass through the 10-foot trap and Of strips made Of canvas or old These strips dislodge most of the horn flies Printed With ink rHc:ycIed paper on the animals' hàcks and sides. After the flies feed and mate, the female is ready to deposit eggs. Cattle passed freely through the trap, leaving behind many of the horn flies that were on them. Left and right arrows move across top level links and expand / close menus in sub levels. These tags generally employ pyrethroid insecticides and, until recently, gave almost complete control of horn flies for a summer season. The flies then are attracted to the light at the top of the trap and fly upward into an inverted-cone trap. While the trap caught some face flies, it did not result in any effective reduction in fly numbers per head. and you can get a PDF of blueprints for the trap. The top is made from plywood. J Dairy Sci. 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). It works so well she no longer has to use her ATV-mounted sprayer for fly control and has reduced her use of insecticide in the cattle’s minerals. The trap reduces the numbers of flies on the animals as they move through it. The sides support panels bearing electric grates, which grates are accessible to flying insects on both the inside and outside of the trap. Bruce's trap is a walk-through system.

The horn fly, Haematobia irritans (Linnaeus), was introduced into the United States more than a century ago. Of course, ALWAYS READ AND FOLLOW LABEL DIRECTIONS FOR SAFE USE OF ANY PESTICIDE! Diapausing pupae produce adult horn flies the following spring. As summer progresses, more horn fly eggs develop but mature only to the pupal stage. The development of insecticide resistant horn flies in some areas, plus interest in non-chemical fly control, spurred reinvestigation of fly traps. She moves to the rear of the cattle host, flies to the ground as the animal defecates, and becomes covered by dung. Be careful of wasps that may construct nests between the elements. A walk-through trap designed to collect horn fly adults from cattle can also lower populations. 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. Although many systemic insecticides show an effect against horn flies, most (such as ivermectin) are too costly for the frequent reapplications required. 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. Because flies are attracted to light, they travel toward the screened sides of the trap. 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. I just started wrapping over the old paper with the new. They use a tubular mouthpart to pierce the skin and get a blood meal. JavaScript seems to be disabled in your browser.

A sharp knife will cut through it to throw it away.” Kevin says that he caught face flies, horse flies and deer flies. Ideally, the tunnel-like trap should be placed where animals can pass through it several times a day. 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. These strips dislodge most of the horn flies on the animals' backs and sides. Because flies are attracted to light, they travel toward the screened sides of the trap. As the cattle enter the trap, canvas brushes their backs, which disturbs the horn flies. As with dust bags and back rubbers, placement of fly traps is important. 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. 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 2An interior view of the trap shows the screen placement in a trapping element. Pathways to water, feed, or mineral supplements are ideal.

It may be necessary to wash the element screens clear with water if they become clogged with mud and debris. After cattle are accustomed to the trap, they often pass through it several times a day and seem to realize its benefit. The best site for placement of the trap is between pasture and the source of water. Although other pest flies, including the stable fly, face fly, and house fly, were captured in the trap, the effect was most significant on the horn fly. The canvas strips have been removed for clarity. S123 Ag Science – North A walk-through fly trap designed in 1938 by W. G. Bruce was tested for two field seasons in Missouri. Figure 1The trapping elements are in place, as viewed from the side. Male and female horn flies feed on blood by using rigid mouthparts underneath their heads. Making the frame of the trap from welded square steel makes the strongest trap. Bruce spent the rest of his career working with pesticides and studying their use for horn fly control. Cattle enter through either end, pass through the 10-foot trap and contact a series of strips made of canvas or old carpet. As cattle pass through the trap, strips of canvas or old carpet dislodge flies from the animals. After a time, which varies depending on temperature, the eggs hatch, and maggots develop in the dung. As shown in Figure 4, you can use wire cattle panels to funnel cattle into the trap. 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 outside area around the trap should be fenced to exclude cows. Since then, it has become one of the most important fly pests of pasture and range cattle. Sprays, rub-ons or pour-ons were effective, but many insecticides, such as DDT and toxaphene, are no longer permitted. Holes punched through the small end of the triangle permit the flies to crawl toward the outside of the trap (Figure 3).

Help improve lives, communities and economies throughout the state. A zigzag screening in the trapping elements functions as the cone (Figure 2). Because flies Cattle producers dissatisfied with the performance of insecticidal ear tags requested information about alternative control methods. By 1986 the problem of horn fly resistance to pyrethroids was widespread enough in Missouri to warrant re-evaluation of Bruce's trap design. The animal exits the trap with fewer flies on it, and the trapped flies cannot escape. Since then, it has become one of the most important fly pests of pasture and range cattle. The horn fly, Haematobia irritans (Linnaeus), was introduced into the United States more than a century ago. It is a guide for people considering the use of alternative types of fly control. As cattle walk through the device, the flies are brushed off of them. Most biting flies circle around the host before landing to bite. 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. 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. 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.

Irritation and feeding by horn flies, especially on yearling cattle, results in reduced weight gain during horn fly season. Once captured, they are unable to escape. 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. Up and Down arrows will open main level menus and toggle through sub tier links. Bruce's trap is a walk­through system. The retail price of materials is estimated at about $300. Scavenger insects make frequent cleaning of the elements unnecessary. The dislodged flies are drawn to the light at the bottom of the trap coming through louvered screens. Field studies conducted in central Missouri during 1986 indicated the trap produced roughly 50 percent control of horn flies when averaged over the season. Cattle enter through either end, pass through the 10-foot trap and contact a series of strips made of canvas or old carpet. These elements are held into the framing with screw hooks and eyes and can be removed for maintenance. 2014; 97(7):4624-31 (ISSN: 1525-3198) Denning SS; Washburn SP; Watson DW 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. Lexington, KY 40546-0091 859-257-4772, Students   /   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. The nonchemical walk-through traps require cattle to pass through them to obtain water or access salt. 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 … If you cannot easily fence off the water source, you can encourage use of the trap with mineral blocks or a mineral station. Resistance to the pyrethroids developed in southern horn flies, however, and spread northward. This feeding activity is painful and annoying to cattle. The development of insecticide resistant horn flies in some areas, plus interest in non-chemical fly control, spurred reinvestigation of fly traps. Ask for plan 1-904-C-6, “Fly Trap”. Cattle enter through either end, pass through the 10­foot trap and contact a series of strips made of canvas or old carpet. Experiments will be designed to demonstrate pasture fly control before and after fly populations have established and thresholds had been exceeded. University of Kentucky research has shown differences in the range of 12 pounds per head resulting from horn fly control. The animal exits the trap with fewer flies on it, and the trapped flies cannot escape. Flies are attracted to the large dark trap because it appears to be a potential host.
