Summerlin JW, Petersen HD, Harris RL. Host ranges of six solitary filth fly parasitoids (Hymenoptera: Pteromalidae, Chalcididae) from Florida, Eurasia, Morocco, and Brazil. The horn fly undergoes complete metamorphosis, and has four major stages of development: 2000. Side views of horn fly, Haematobia irritans irritans (Linnaeus) (top); and stable fly, Stomoxys calcitrans (Linnaeus) (bottom). This pest is now found throughout the Americas, as well as in Europe, Asia, and the non-tropical regions of Africa. Effect of larval rearing temperature and maternal photoperiod on diapause in the horn fly (Diptera, Muscidae). A colony of white-eyed horn flies was established from this single individual and has been maintained in the laboratory as visible genetic markers such as an eye color mutation in an economically important species like the horn fly may be useful for behavior and population dynamic studies, as well as release and recapture studies. Abstract. 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). In order to correlate the H. irritans postembryonic development with gametogenesis, a standard life cycle on cattle dung was established under laboratory conditions at 29 1° C and 90% relative humidity. Adults: The adult horn flies have brownish-gray or black bodies and are shiny, with slightly overlapping wings that are held flat over the abdomen. Spalangia sp. To combat this, the use of organophosphates and piperonyl butoxide as a synergist are now recommended to be alternated with pyrethroid to help slow resistance. [5] Each adult tree swallow will consume about 2,000 insects per day during an average 45 day nesting period. Fly control tactics are moving away from dependence on pesticides, due to concern for the environment and pests developing resistance to insecticides.

Larvae eventually migrate to the subcutaneous tissue of the cattle’s thoracolumbar region and cut holes in the skin for respiration. Figure 6. Horn flies (Haematobia irritans or Lyperosia irritans) are tiny flies, one of the insects most damaging to cattle in Europe, North and South America, and Asia. Though insecticide technology has been largely, if not exclusively, relied upon for managing horn flies, resistance to many of the insecticides has been widely reported and demonstrated to occur through several known mechanisms, including target site insensitivity and thorough metabolic detoxification of insecticides (Szalanski et al. Distribution of horn flies on individual cows as a percentage of the total horn fly population. The biology and behavior of Hister abbreviatus F. were studied in the laboratory to define the developmental history and habits of this manure-attracted beetle and to evaluate its potential as a control agent of immature stages of the horn fly, Haematobia irritans (L.). Originally, the ear tags were developed and used against such pests as ticks and by 1983 50% of cattle had ear tags. Static thresholds have been established, based on the numbers of horn flies per animal, in order to determine whether the implementation of fly management is economically necessary. The span of larval Horn flies have short life cycles, multiple generations per year, and a large number of flies that are fertile females. Larvae migrate for a while in deeper tissues. It was first described by Carl Linnaeus in his 1758 10th edition of Systema Naturae. internal; oviparous; Average eggs per season 18; Behavior. Horn flies received this name due to 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. 1998). [3], Rotating hens three days behind cattle is an effective method in reducing horn fly populations by scratching apart their habitat as they eat the horn fly larvae. The stable fly (Stomoxys calcitrans) and horn fly (Haematobia irritans) are mainly parasites of cattle that spend the early phase of their life cycle in decaying vegetation, manure and soil, as members of a wide range of other harmful and beneficial arthropods. What Do They Look Like? The first re-ports of attacks on livestock by H. irritans in Argentina and Uruguay occurred in 1991, and since 1993 it is considered an economically important pest. Although both flies have a piercing proboscis, horn flies have longer maxillary palpi relative to the proboscis. XVI World Butiatrics Congress, Salvador: Interlink Consultoria and Eventors Ltd, 1990. vol. Haematobia irritans is not native to the U.S. and originally came from Europe. Journal of the Kansas Entomological Society 68: 303-312. Photograph by Phillip Kaufman, University of Florida. Photograph by Dan Fitzpatrick, University of Florida. Biological insecticides also have gained popularity as alternatives to pyrethroid or organophosphate pesticides. The parents also catch and feed their brood (of 4-7 nestlings) about 6,000 insects per day during an average 20 days spent inside the nestbox. However, they have a well-documented close association with cattle and typically remain on or near cattle throughout their entire life cycle. Several species within this family are important biological control agents of insect pests. Females deposit eggs in soil (0.5–5 cm deep) beneath the manure. 1995, Edwards et al. Interestingly, the red imported fire ant, Solenopsis invicta Buren, also reduces immature horn fly numbers in cattle dung pats as well through predator activity (Summerlin et al. Twenty species of bacteria were isolated from cattle manure and seven species were isolated from the gut of larval horn fly Hematobia irritans (L.). 1992. Pruett JH, Steelman CD, Miller JA, Pound JM, George JE. Lysyk TJ. 1998). 1991. ... Life cycle. Horn flies also are able to vector several Staphylococcus spp. Environmental Entomology 25: 1290-1296. Journal of Economic Entomology 89: 1513-1520. Life Cycle and Transmission BB is principally transmitted by means of ticks o Tick vectors of Babesia bigemina: Rhipicephalus microplus (formerly Boophilus microplus) and Rhipicephalus annulatus (formerly Boophilus annulatus); Rhipicephalus decoloratus, Rhipicephalus geigyi, and Rhipicephalus evertsi are also competent vectors The flies are often most abundant from June through mid-July with a second population peak in mid-to-late August. Cow using walkthrough fly trap to remove horn flies, Haematobia irritans irritans (Linnaeus). Nematodes were confirmed in three instars of intermediate host Haematobia irritans. 2002). Annals of the Entomological Society of America 67: 891-894. It is an obligate blood-feeding ectoparasite, feeding almost exclusively on cattle. Both of these techniques kill only the immature stages of the horn fly and do not affect the adult flies feeding on the animals. Life Cycle: Females lay eggs singly or in small clusters on the bottom edges of freshly passed cow manure. Both male and female imagoes spend their adult stage on the host, while immature stages develop in dung. Self-applicator methods such as dust bags and backrubbers are used mainly for range or pasture herds, and are placed so that the animal cannot avoid coming into contact with it, such as at a gate through which animals pass. H. irritans is of the class insecta. New research (2011) has shown essential oil vapors from 16 species of eucalyptus to have toxicity against Haematobia irritans.[8]. Common name. 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. [6], Parasitic wasps can can reduce fly larvae by 90%. Esterase staining activity in pyrethroid-resistant horn flies (Diptera: Muscidae). 2000). What Do They Look Like? 1992, Cupp et al. Haematobia irritans, the horn fly, is a small fly (about half the size of a common housefly).It was first described by Carl Linnaeus in his 1758 10th edition of Systema Naturae.It is of the genus Haematobia which is the European genus of bloodsucking flies. Both the male and female have slender, black, piercing mouthparts which project forward from the bottom of the head. 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. This thesis reports the results of experiments designed to provide information on the developmental biology of the immature stages of the buffalo fly. Larvae: The newly hatched maggots are white and about 1.5 mm long with a slender pointed head. The flies remain on the host, for most of their life cycle, leaving only to lay their eggs on other hosts - spreading the infection. Some species remove and bury balls of manure containing their eggs. Cytology. Horn flies also must lay eggs in undisturbed, fresh manure, whereas stable flies seldom lay eggs in fresh manure, opting rather for manure-straw mixtures, urine-soaked feed and straw, feeding waste sites, grass clipping piles, and round hay bale feeding sites. Journal of the Kansas Entomological Society 11: 88-93. 1992. 1991). 1998). This helps spread manure and disrupt fly-larvae development. The horn fly, Haematobia irritans is an obligate haematophagous cosmopolitan insect pest. The life cycle from egg to adult can be as short as 10 days although it is usually about 14 days. ...

Life cycle: Development times of various pupal parasites of house flies and horn flies in Florida. Diptera. A practical trap for the control of horn flies on cattle. Figure 1. Haematobia irritans , commonly known as the horn fly, is a globally distributed blood-feeding pest of cattle that is responsible for significant economic losses to cattle producers. Calves and dairy cattle cannot sustain high numbers of flies without sustaining measurable damage; 50+ flies per lactating dairy cow is considered to be of economic importance. Figure 9. 1987, Hogsette et al. The horn fly, Haematobia irritans (Muscidae: Stomoxyinae), is an Old World species (Palearctic region) and an obligate blood feeding ectoparasite of cattle ( Stone et al., 1965; Zumpt, 1973 ). Both the male and the female subsist completely on blood, using their sharp mouthparts to pierce the animal's hide to suck it out. It is of the genus Haematobia which is the European genus of bloodsucking flies. Larvicidal activity of endectocides against pest flies in the dung of treated cattle. Butler JF, 1990. The ear tags are made of a PVC matrix impregnated with pyrethroid, and can be effective for between 16 and 24 weeks. Life cycle In order to correlate the H. irritans postembryonic development with gametogenesis, a standard life cycle on cattle dung was established under laboratory conditions at 29 ± 1º C and 90% relative humidity. 1974. 2:1210-1215. Environmental Entomology 35: 405-412. (December 2005). More recently, control of the horn fly by using ear tags on cattle has been extremely successful. Mechanical control: An old, and perhaps effective, non-chemical control tactic that has been critically evaluated in recent years is the walk-through horn fly trap. 1999. Journal of Economic Entomology 80: 451-454. The insect's current distribution encompasses much of the tropical, subtropical, and temperate regions of the Northern Hemisphere, 1 including Europe, North Africa, and Asia Minor. A single manure pat without dung beetles can generate 60-80 adult horn flies. and deer flies (Chrysops sp. MedicalandVeterinaryEntomology, 20, 325–328. It is an obligate blood-feeding ectoparasite, feeding almost exclusively on cattle. It feeds off cattle and buffalo, and causes irritation which can result in reduced production if cattle are heavily infested. Cytology. 2006). 1995. Buffalo flies (Haematobia irritans exigua) (BF) and closely related horn flies (Haematobia irritans irritans) (HF) are invasive haematophagous parasites with significant economic and welfare impacts on cattle production. Medical and Veterinary Entomology 22: 188-202. Buffalo flies (Haematobia irritans exigua) (BF) and closely related horn flies (Haematobia irritans irritans) (HF) are invasive haematophagous parasites with significant economic and welfare impacts on cattle production. The life cycle from egg to adult takes about 10 to 20 days, depending on environmental conditions. It feeds off cattle and buffalo, and causes irritation which can result in reduced production if cattle are heavily infested. Cupp EW, Cupp MS, Ribeiro JMC, Kunz SE. 2006. Figure 10. 1998, Gillespie et al. 1992, Cupp et al. The horn fly, as can be gleaned from its taxonomic designation Haematobia irritans, is an irritant to livestock. 1980. The life cycle of Haematobia irritans was partially described elsewhere (Basso et al. Photograph by Dan Fitzpatrick, University of Florida. Both male and female imagoes spend their adult stage on the host, while immature stages develop in dung. Mitosis and meiosis were studied in neuroblasts of sub-esophageal ganglia of third-instar larvae and in spermatocytes of pharate and freshly eclosed adults respectively. The horn fly, Haematobia irritans irritans (L.) in the dipteran family Muscidae, is an ectoparasitic pest of livestock that was originally described from southern France. Managing the horn fly (Diptera: Muscidae) using an electric walk-through fly trap. 1981, Lysyk and Colwell 1996, Floate et al. Composting techniques must allow for the entire mass to reach temperatures that will kill insect eggs (e.g. A review of ectoparasites and their effect on cattle production. The buffalo fly, Haematobia irritans exigua, is a small biting fly 3.5 – 4 mm long. The horn fly eggs take 1 to 2 days to hatch. Effect of horn fly and internal parasite control on growth of beef heifers. 2001). Haematobia irritans, while able to fly, almost never leaves its host, instead staying on the same cow to feed 24 hours a day. Geden CJ, Moon RD, Butler JF. Pruett, J.H., Miller, J.A., Steelman, C.D. Haematobia irritans, the horn fly, is a small fly (about half the size of a common housefly). The horn fly is considered one of the most economically devastating pests of the beef cattle industry in the United States (Byford et al. Feeding on the fresh dung, larvae develop through three instars in four to eight days before reaching a mature size of 6.5 to 7.5 mm (Lysyk 1991, 1992). 1994. Life cycle Adult flies lay as many as 800 eggs on hairs of cattle’s legs. Journal of Economic Entomology 95: 1113-1118. Lysyk TJ. Photograph by Jerry Butler, University of Florida. Haematobia irritans: Economic Importance and Bionomical Characteristics. 1981. The common name of Haematobia irritans comes from the fact that these flies often cluster in the hundreds around the base of the horns of cattle. Endectocides also have gained popularity with cattle farmers in recent years under a variety of trade names. Photograph by Lane Foil, Louisiana State University. Blood-sucking flies, such as horn flies (Haematobia irritans), stable flies (Stomoxys calcitrans), horse flies (Tabanus sp.) 1992). No other differences from the wild-type flies were detected in the external characteristics of the mutant phenotype or in egg viability. Appearance. 2003. A female stings a pupa, lays a single egg, and the wasp larva feeds on and kills the pupating fly. The life cycle from egg to adult fly (Figure 1) takes 9–11 days. Found primarily in and around the states surrounding Kansas. 1991. 1986. 1992). Dung beetles of the family Scarabaeidae, as well as other predaceous beetles of the families Staphylinidae and Histeridae, are important natural predators of larval horn flies in the manure (Hu and Frank 1996, Oyarzún et al. Photograph by Dan Fitzpatrick, University of Florida. In order to correlate the H. irritans postembryonic development with gametogenesis, a standard life cycle on cattle dung was established under laboratory conditions at 29 1° C and 90% relative humidity. Nickerson SC, Owens WE, Boddie RL. Studies have shown the influence of temperature on ovarian development and egg laying [6] [7], as well as the interference of physical and nutritional properties of bovine feces on egg production [9] and lar- [8] haemosporidian minute protozoans parasitic at some stage of the life cycle in blood cells of vertebrates including many pathogens haematopoiesis the formation of blood cells in the living body haematohiston a colorless protein obtained by removing heme from hemoglobin; the … The bloodsucking horn fly, Haematobia irritans (L.) (Diptera: Muscidae), is one of the most damaging pests of pasture cattle in many areas of the world. 2001. Life cycle. Hosts. Male and female horn flies feed only on blood during their adult stage, whereas other blood-feeding flies, such as the stable fly, will consume nectar. The common name of Haematobia irritans comes from the fact that these flies often cluster in the hundreds around the base of the horns of cattle. 1991).

This results in elevated heart and respiratory rates, reduced grazing time, decreased feeding efficiency and reduced milk production in cows, which can result in decreased weaning weights (Byford et al. Horn flies have short life cycles, multiple generations per year, and a large number of flies that are fertile females. [2] Manure and wasted hay can be spread thinly for quick drying, or composted. Kerlin RL, Allingham PG. part of Muscidae, eggs in fresh cow manure, hatch in few hours, larva for 7 days, pupa in soil, adults can fly several miles, both sexes on cattle or horses constantly, feed 20-30 times per day, largest numbers May-September. Effect of the red imported fire ant (Hymenoptera: Formicidae) on dung-inhabiting arthropods in Florida. (Skidmore, 1985) Key Reproductive Features; semelparous; sexual; fertilization. Knowledge on the genetic characteristics of the horn fly The resulting larval (maggot) stage, which consists of three larval instars (wingless), develops quickly and can last as little as four days. Figure 8. PLAY. Cattle producers are encouraged to protect these natural enemies of the horn fly, as without them, populations would assuredly be much higher. Biology and control of tabanids, stable flies and horn flies. Adults use liquid components as nourishment and lay eggs in the manure pat. [4], The tree swallow (Tachycineta bicolor) is also an effective predator of Haematobia irritans and can be attracted by building tree-swallow houses spaced approximately 100 feet apart. Lateral view of an adult horn fly, Haematobia irritans irritans (Linnaeus). 2003). Distribution ... Life cycle of the buffalo fly A female horn fly oviposits, or lays, an average of 78 eggs during her adult lifespan of approximately six to seven days, but can lay up to 100-200 eggs (Krafsur and Ernst 1986). Larval growth ceased if dung moisture fell to 64 per cent, of wet weight. Deoxyribonucleic acid fingerprinting of. Horn fly populations on animals in temperate areas are usually low at 200 per animal or less, flies may reach extreme numbers on cattle in the tropics and semitropics (Nearctic and Neotropical region) with … Stress and blood loss from horn flies can reduce cattle weight gain and milk production. 2005). Lysyk TJ, Colwell DD. Beef cows can tolerate upwards of 200 flies per animal, while bulls can tolerate the greatest number of horn flies (Schreiber et al. Adult females leave the host only long enough to lay their eggs in fresh manure, the material necessary for larval development, and the complete lifecyclerangesfrom10to20days(Oyarzúnetal.,2008).Thus, areaswithlongerwintersandshortersummerswillhavefewer generationsofhornfliesthanwarmerareas. 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. Eggs survived temperatures between 11.0.and 37.0°C, while larval and pupal development was restricted to temperatures between 15.0 and 35.0°C. The insect's current distribution encompasses much of the tropical, subtropical, and temperate regions of the Northern Hemisphere, 1 including Europe, North Africa, and Asia Minor. The horn fly undergoes complete metamorphosis, and has four major stages of development: The first stage is the egg, which is laid in fresh feces, and hatches quickly. Rate of development is slowed in cooler temperatures. To date, horn fly control has not been accomplished solely using naturally-occurring or augmentative biological control, principally due to the widely distributed cattle dung pats (and therefore horn fly pupae) and difficulty in getting released wasps to these sites. Another approach to this technique, the bolus, provides several weeks worth of control from a single treatment. STUDY. Miller JA, Kunz SE, Oehler DD, Miller RW. Embryogenesis lasted 24 1 hours, whereas the full cycle until imago ecdysis lasted 12 days (Figure 1A). [1], H. irritans is the smallest of the biting muscids, gray in color, approximately ​3⁄16 in (4.0 mm) in length. In addition to the teat damage they cause, feeding flies can introduce the bacteria into open wounds, causing significant infection (Edwards et al. Both male and female imagoes spend their adult stage on the host, while immature stages develop in dung. Horn fly, Haematobia irritans 33 Insect Life Cycle 34 (No Transcript) 35 Horn fly, Haematobia irritans. A cloud of horn flies (the numerous white specks), Haematobia irritans irritans (Linnaeus), feeding on cows. Insects, such as Haematobia irritans L., depend on several abiotic and biotic factors during their short life cycle [4] [5]. Mendes J, Linhares AX. The horn fly, Haematobia irritans irritans (Linnaeus), is one of the most economically important pests of cattle worldwide.
