These pests take up to 40 blood meals a day with piercing mouthparts. Altosid ® IGR is used on cattle raised on pasture where horn flies are the predominant fly species of concern. 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. be found on the back and sides of the animal. The wasp probes the pupa twice, once to kill the horn fly larva and a second time to lay an egg. After some time (a few days or months depending on the fly … breaks the horn fly life cycle, preventing pupae from developing into biting adult flies. Horn fly projects are conducted on an annual basis to see how different insecticidal ear tags perform from year to year. 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. Females lay eggs in fresh cattle manure, which is where immature forms complete development. Found on the backs of cattle, horn flies are the most pervasive and costly external parasites of cattle in North America. “If you don’t keep fly control mineral out for 30 days after the first frost, you also risk temperatures bouncing back and allowing more fly generations to survive,” says Backes-Belew. 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.

Life cycle Horn fly eggs are laid in cow manure pats, where they hatch as maggots. Withholding months. 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 develop from the egg to adult stage within 10 to 20 days, and the adults live for about 3 weeks, feeding 20 to 30 times a day. Over a period of a few days, she will produce five or six batches of eggs. Without a fly control program in place, horn fly populations can swell up to 4,000 flies per animal. Discover (and save!) The adult can live anywhere from 2 to 4 weeks. Adult horn flies spend their entire life on their host, and females leave only to oviposit eggs on fresh cow feces, where larval and pupal development occurs. HORN FLY CONTROL OPTIONS.
