Interpretive Summary: The stable fly is an economically important pest of livestock. Stable fly. What does the stable fly cause to my dog? Cattle heavily infested with stable flies have been noted to become anemic and milking cows have been observed to show lower milk production. Flies and Mosquitoes of Cats. Horn flies feed on the ventral midline, and abscesses are commonly found in the area where fly irritation occurs. These flies are most active in the daytime, breed in old manure or other wet, decaying matter and can travel in a range of up to 100 miles. They also expose employees working on the feedlot to diseases such as E. Coli and Salmonella. The infection is spread by exposure to contaminated soil, by horn flies, stable flies and house flies, and may also be spread by horse-to-horse contact. The accumulation of stable fly bites leads to a certain degree of anemia, weight loss in cattle, reduced milk production in dairy cattle. Mastitis, the most costly disease of dairy cattle, is caused when the bacteria invade the teat and gain entrance to the mammary gland. Because it has sponging or lapping mouthparts, the housefly cannot bite; a near relative, the stable fly, however, does bite. The difference between ticks and flies related to anaplasmosis is that biting flies are mechanical vectors of anaplasmosis. Areas along fence rows, under feed bunks, or wherever manure and straw or decaying matter can accumulate should be kept clean. opthalmia, mastitis, parafilariasis. This is due to the inability of the dog to defend their ears. In addition to inflicting a painful bite when blood-feeding, the stable fly can carry certain microbes that cause disease in domestic animals. The stable fly pictured can spread anthrax and mycoplasma. The stable fly bites humans at rest in the outdoors. Now found worldwide, the species is considered to be of Eurasian origin. Stomoxys calcitrans economically affects humans in two ways: livestock reduction and disease. Mass attacks on livestock can cause loss of blood, flesh, lowered milk production and reduced vitality thus making the animals susceptible to disease as well as, causing tissue and hide damage. In addition, bite wounds can be sites for secondary infection. These species carry diseases including equine infectious anemia, anthrax, contagious conjunctivitis and eyeworms. The bites of the stable fly produce skin lumps that are called external parasitic nodules. The nodules become worse when rubbed. Flies that cause irritation and economic loss include the house fly, the heel fly, the horn fly and the stable fly. Stable flies cause irritation and weakness in animals and ac-count for much blood loss in severe cases. The biggest difference is that the stable fly has a bayonet-like proboscis for blood sucking. High temperatures and drought conditions often precede outbreaks. Disease Transmission: Not an important vector of animal pathogens. Common to horses being stabled or horse that are kept close together. • The disease is vectored by triatomine (cone‐ nosed) bugs. It is known to cause intestinal myiasis in humans. Since they do take blood meals, severe cases can result in excessive blood loss and bite wounds can develop infections. Good sanitation practices can reduce the stable fly population by up to 90%. One of the most frustrating flies is the face fly which spreads the organisms that cause pink eye. Horse flies are even worse than normal house and stable flies. The bacterium that causes Pigeon Fever survives and thrives in soil contaminated by fecal matter.

Egg to adult development requires three to four weeks. Mass attacks can cause livestock to lose blood and limit their milk production. The stable fly lays its eggs in piles of decaying vegetation such as grass clippings, manure and urine, contaminated hay and wet feed. Houseflies, face flies and stable flies transfer parasitic nematode larvae (e.g., Habronema species) to moist areas around the eyes, nostrils, mouth, genitalia and wounds. The house fly and other types of “filth flies” can become nuisance pests, but also are important for their potential to harm humans and animals. Due to its short life cycle and a high reproduction rate, the species often builds up high population densities, when suitable breeding sites and host species are present. Pigeon fever This disease caused by bacteria transmitted by horn, stable, and house flies, creates swellings on your horse’s chest, puffing him up like a pigeon. These infestations and infections cause distress to companion animals, and in livestock industry the financial costs of these diseases are high.

The house fly is found in and around barns and feeds on waste, especially garbage and animal feces. Stable flies may become numerous around premises because females deposit eggs on moist decaying organic matter. Females deposit 80-100 eggs in decaying organic matter, typically wet bedding, wasted feed, and mixtures of manure and straw or other bedding. House flies, for example, can spread diseases such as food poisoning and dysentery. Stable flies, or dog flies (Stomoxys calcitrans), are a type of hematophagous insect with parasitic habits. The common biting fly (Stomoxys calcitrans), also known as the stable fly, is widespread worldwide and looks similar to the house fly but has a proboscis through which it sucks blood.During this blood meal, it can transmit diseases to its host animals. These flies mostly live in fields, farms and rural areas. Stable Fly. What does the stable fly cause to my dog? Intestinal myiasis occurs when fly eggs or larvae previously deposited in food are ingested and survive in the gastrointestinal tract. Insect-borne Equine Diseases Mechanical dermatitis. This is due to the inability of the dog to defend their ears. Moraxella bovis is the primary cause of IBK. The main species present are house flies and stable flies. House flies can spread disease like cryptosporidium, salmonella and E. coli. These flies are primarily a nuisance during the warm summer months. The larvae (maggots) develop in and around the wound and can tear the skin to obtain more food. The habits of filth flies favor the spread of bacteria and other disease-causing organisms. Besides transmission of disease agents, the stable fly S. calcitrans causes considerable irritation by its frequent biting activity. Anthrax, an acute disease caused by Bacillus anthracis, affects all classes of mammals, including man.

Flies, including stable flies and mosquitoes (which are also classified as flies, or Diptera), can inflict painful bites while feeding on the blood of humans and other animals, and some species transmit disease. Ticks cause blood loss, discomfort, and spread diseases in cattle such as bovine babesiosis, tick fever, Lyme disease, and anaplasmosis. Similarly, stable flies cause significant pain when feeding on the legs of the animals that will cause the animals to react that then interrupts feeding by this fly. Apart from the flies mentioned above, surface parasites can also cause equine diseases. These, and other species of flies, are most prevalent in summer and autumn and are particularly active during warm humid periods. The habits of filth flies favor the spread of bacteria and other disease-causing organisms. Like houseflies, which have no piercing mouthparts, biting flies can spread disease-causing pathogens that hitchhike on the flies’ legs, abdomen, or mouthparts, transmitting disease from ill to susceptible animals. It is only after 4 days since infected that these symptoms start to occur, however, sometimes it takes up to 2 weeks to start showing symptoms. They belong to a large, complex order of insects called Diptera. If you notice livestock bunching, that is a good indication that stable fly bites have reached the point of impacting production and profits. Stable flies were collected on alsynite traps placed near the exhaust fan of the close-sided tunnel-ventilated buildings, suggesting blood seeking flies are attracted by olfactory cues. [1] Unlike most members of the family Muscidae, Stomoxys calcitrans ('sharp mouth' + 'kicking') and others of its genus suck blood from mammals. Figure 7. It pierces the skin and sucks blood as a food source. “They can transfer diseases such Equine Infectious Anemia, a very fatal disease that we don’t have a cure for,” she said. Horn flies are very costly to control but cannot be ignored; horn flies consume up to a pint of blood each day. How do flies spread disease? The house fly is able to spread disease through several routes. It does not bite like the horse fly or tsetse fly in order to inject the pathogen into a person.
