Species of Flies of Importance in Livestock 1. Flesh Fly Sarcophaga spp. Known for being a nuisance to livestock, the flesh fly is often involved in the spread of diseases and infections. 2. Horse Fly Gasterophilus sp. These flies are particularly troublesome for horses and can cause stress, irritation, and even transmission of diseases. 3. Horse Fly Tabanidae spp. Another common pest for horses, known to bite and cause pain, leading to infection and even a decrease in productivity. 4. Horn Fly Haematobia irritans Horn flies primarily target cattle, causing skin irritation, reduced weight gain, and a potential decrease in milk production. 5. Sheep Bot Oestrus ovis This fly targets sheep and causes botfly larvae to infest the nasal cavity, leading to irritation, possible infection, and health decline. 6. Stable Fly Stomoxys calcitrans Stable flies feed on the blood of cattle, horses, and other livestock. They can significantly impact the overall health of animals, causing stress and anemia. 7. Face Fly Musca autumnalis These flies are a common problem for cattle and are known for transmitting pinkeye, a contagious eye disease. 8. Screwworm Fly Cochliomyia hominivorax Screwworm flies cause serious damage to livestock by laying eggs in open wounds, leading to severe infections and even death if untreated. 9. House Fly Musca domestica House flies may not directly harm animals, but they can spread diseases and act as vectors for pathogens, which could lead to infections in livestock. Fly control is essential for maintaining healthy livestock, as these pests can cause a variety of health issues and economic losses. Knowing which species to look out for can help with better management strategies.
