Horn Flies are smaller flies, they will Horn flies tend to rest quietly on the back and shoulders of cattle until disturbed. In the southern USA, the life cycle can be as short as 1 wk, but in cooler climates and in the spring or fall, development can take 2–3 wk. Horn Flies are a greater problem in pastured cattle because the females need an intact fresh manure pad to complete the life cycle. http://www.progressivecattle.com/topics/management/6697-reducing-fly-numbers-on-pastured-cattle. Life Cycle. Growing cattle can gain an extra 1.5 The adult can live anywhere from 2 to 4 weeks. 1973 Oct;66(5):1239-40. Horn flies received this name because of their habit of clustering around the horns of cattle, although they typically prefer to settle on the backs of cattle during the cooler parts of the day and on the belly during the hotter part of the day. They have a short pupation period, so their populations can easily grow until there are several hundred insects per animal. Horn fly maggots only develop in cattle manure and do best in the grass manure of pastured cattle. They have been known to feed on horses, dogs, swine, and sometimes humans. The life cycle of the horn fly takes place only in fresh cattle manure. Making manure magic One of the most convenient and consistent ways to control horn flies in cattle is giving them a mineral supplement that contains an Insect Growth Regulator (IGR). they have a complete life cycle (egg, larvae, pupae, adult). It breaks the horn fly life cycle by preventing pupae from … The stress caused by horn flies causes interrupted grazing patterns and reduced weight gains in cattle. Starting in late August, a portion of the population goes into diapause, a period of suspended development, the overwintering phase of the fly’s life cycle. Life cycle: Horn flies are holometabolus, meaning they have a complete life cycle (egg, larvae, pupae, adult). In untreated herds, fly infestations can increase rapidly to upwards of 4,000 flies per animal. How to control: Economic infestations range from 200 to 300 flies and up. While you will never eliminate all flies on cattle, maintaining a fly control program will help limit populations to less than 200 flies per animal, the economic threshold established for horn flies on beef cattle. which is manifested in growing cattle. Horn flies survive the winter as pupae in the soil. Using a fly management program to limit flies on cattle will help promote herd health. These pests take up to 40 blood meals a day with piercing mouthparts. Adult horn flies live 2-4 weeks, taking 20-40 blood meals per day. Chemical control: Several chemical control methods can help reduce the number of horn flies on cattle: ear tags, sprayers and dusters, feed additives, and boluses.

The adult horn fly emerges as a small, black insect, approximately 4 millimeters long. The life cycle from egg to adult takes about 10 to 20 days, depending on environmental conditions. When flies emerge, they mate and the females seek a protein source that is necessary for egg development. Over a period of a few days, she will produce five or six batches of eggs. This feed-through fly control uses the active ingredient to interrupt the transformation from pupae to biting adult flies. To understand how to effectively control this biting pest, it helps to understand a typical horn fly life cycle: Female adult flies leave the backs of cattle briefly to lay their eggs in fresh manure. Horn flies spend months. to take a blood meal to reproduce. develop in late May or June and persist into the fall. Horn flies may take between 20 and 30 blood meals per day (Campbell, 1993).

Horn fly projects are conducted on an annual basis to see how different insecticidal ear tags perform from year to year. (Photo courtesy of Dave Boxler) LINCOLN — With summer grazing season almost here, now is the time to prepare a horn fly management plan. Horn flies rarely leave their host except to lay eggs, to move to other cattle in the herd, or when cattle enter buildings. Horn flies have short life cycles, multiple generations per year, and a large number of flies that are fertile females. In Nebraska, horn flies overwinter as pupae in or beneath cattle manure pats. pupating. Horn Flies are a greater problem in pastured Most feeding occurs along the underline of the animal and results in scabby, often bleeding, sores. Each female can lay up to 500 eggs so very large populations can build up over the summer. After finding a host, she drills into the puparium (outer cover of the pupa) with her ovipositor and deposits one or more eggs. https://www.youtube.com/channel/UCwre5rXMLBGKKb4TbhyvZwQ, Don’t Fall Behind: Late Season Feeding 101, Feeding Tips for Effective Horn-Fly Control, Make an Impact on Horn Flies without Impacting the Environment.
