Biology and control of tabanids, stable flies and horn flies. More recently, insecticides formulated into pour-ons are increasingly used. Figure 3. Horn fly control can mean an additional 12 to 20 pounds of weight per calf over the summer months and can result in less weight loss per nursing cow as well. Chemical control: Insecticide-impregnated ear tags became a popular and effective method for managing horn fly populations, due to the advent of low cost, highly persistent pyrethroid and organophosphate pesticides (Szalanski et al. After finding a host, she drills into the puparium (outer cover of the pupa) with her ovipositor and deposits one or more eggs. Extensive horn fly feeding can also severely damage cattle hides, which results in poorer quality leather (Pruett et al. Horn fly allergy (allergic dermatitis) During the horn fly season, cattle often develop a skin allergy to the saliva of the biting horn flies. Horn flies. 1992. Hogsette JA, Prichard DL, Ruff JP.

This pest is now found throughout the Americas, as well as in Europe, Asia, and the non-tropical regions of Africa. The pesticide remains in the dung and can significantly reduce immature horn fly numbers for up to two months after application (Miller et al. Horn flies differ fro… Cattle producers are encouraged to protect these natural enemies of the horn fly, as without them, populations would assuredly be much higher. Kuramochi K, Nishijima Y. The male and female horn flies both take bloodmeals multiple times a day (20-30). They can be seen on the withers, back and side of the cattle and will move to the belly during the hottest parts of the day. Spalangia sp. Typically, Horner syndrome results in a decreased pupil size, a drooping eyelid and decreased sweating on the affected side of your face. All these symptoms result in … Inability to fully extend or bend the knee joint. Just in the United States, hundreds of millions of dollars in losses are attributed to the horn fly annually, while additional millions are spent annually on insecticides to reduce horn fly numbers (Kunz et al. symptoms of pests (Daufman and Rutz, 2010). Horn fly adults are typically 3 to 5 millimeters in length and live for 2 to 4 weeks. Horn flies and stable flies are active during the day time. Annals of the Entomological Society of America 67: 891-894. 1992). Larvae: The newly hatched maggots are white and about 1.5 mm long with a slender pointed head. Modern Versions of Spanish Fly. It is an obligate blood-feeding ectoparasite, feeding almost exclusively on cattle. Photographs by Dan Fitzpatrick (horn fly), Jerry Butler (stable fly), University of Florida. This and other dung beetles bury large portions of the manure and accelerate manure drying, creating competition for the larvae of the horn fly, Haematobia irritans irritans (Linnaeus), that live in the pat. Therefore, because the adult flies are not killed, and because new adult flies may emigrate from nearby untreated herds, feed-throughs are not considered cure-all treatments (Baldwin et al. Typically found on cattle of the western and southwestern United States and Canada, S. stilesi can affect up to 80 to 90% of a herd (Hibler 1966). Some products can be sprayed directly to the infested manure pats while others can be administered as a feed additive or bolus. 1991. Journal of Medical Entomology 23: 188-195.

Horn flies are external blood feeders and will bite an animal 20-30 times per fly per day. These pesticides are injected or topically applied to and absorbed by cattle and are excreted unaltered in the manure. When insecticide is reapplied to the backrubbers and dustbugs every two to three weeks, they are reasonably effective for managing horn flies (Baldwin et al. You no longer have to risk your health to bring the romance and passion back into the bedroom. These traps utilize the horn fly's reluctance to enter a darkened building to remove the flies from the animals and then trap or kill the flies with sticky traps or electrocution as they leave the animals. Horn flies suck blood, irritate and annoy, reduce weight gains and cause weight losses. 2010). 1987. The eggs hatch between one to two days after being laid (Foil and Hogsette 1994). Pupae: The pupae are 3 to 4 mm long and white at first, the outer pupal covering sclerotizes, or hardens, turning dark reddish-brown over several hours. It is found in subtropical and tropical climates from the extreme southern United States to Argentina. Horn flies occur mostly on the cow and usually only by incident on the calves. More modern designs of this technique are reported to provide up to an 85% reduction of fly numbers (Watson et al. The risk and hazards of using insecticide should be weighed by each particular farmer. Although the average meal size is only 1.5 mg, or 10 µL, of blood per feeding (Kuramochi and Nishijima 1980), each fly takes between 24 to 38 blood meals per day (Foil and Hogsette 1994).

The time required to complete the life cycle of a horn fly is between 10 and 20 days, depending on the temperature and time of year (Campbell 2006). Horn flies are commonly reported on beef cattle in large numbers, with thousands of flies occurring on individual animals. After several weeks, an inflammatory reaction occurs in the skin, and many hair follicles are destroyed. Horner syndrome usually affects only one side of the face. Figure 5. Cow using walkthrough fly trap to remove horn flies, Haematobia irritans irritans (Linnaeus). Feed-through applications, where certain pesticides are mixed into cattle feed, result in the chemical passing through the cattle's digestive tract and hence into the manure. Three general approaches to reduce problems include: 1)    Prevent breeding by making manure unavailable or too dry or wet for the larvae to survive or kill the larvae before they become adults, 2)    Kill adults before they cause harm or start to produce eggs, 3)    Exclude adults entrance by using screens or other barriers. Keeping the cattle pens and calving environment clean is vital to break the fecal-oral contact cycle and, in turn, prevent scours. Larvicides provide control against developing larvae. 1992). Click for a hub of Extension resources related to the current COVID-19 situation. Summerlin JW, Petersen HD, Harris RL. 1994.
