<h1>In the breeding of cattle, flying insects will affect the breeding of cattle, let's take a closer look at it specifically: the prevention and control of common flying insects in cattle and their corresponding flying insects. </h1>
1. Mosquitoes
There are many types of mosquitoes, including Aedes mosquitoes, Anopheles mosquitoes, Culex mosquitoes, mandelos and scaly mosquitoes. When these mosquitoes congregate in large numbers, they attack people and animals, and mosquitoes suck blood and spread disease. The larvae and pupae of mosquitoes live in water and feather into adults in 5 to 21 days. The method of controlling mosquitoes on a large scale is to remove sewage or treat sewage with oil agents, synthetic pyrethroids and other insect repellents. The cost of insect repellents for cattle is prohibitive, and semi-automatic coaters are also required. In addition, mosquito infestations can be prevented by using mosquito nets for smaller herds.
2. Black fly
Black flies belong to the family Ants, including blackflies, bison flies, and whiteflies, and are small and have a black or off-white body color. Black flies are present in many countries, and when blackflies gather in large numbers, they can cause a lot of trouble. There is a toxin in the saliva of black flies, which can produce small vesicles after bite, which are transformed into ulcers and are prone to secondary infection, and the larvae and pupa adhere to the reed stalks or branches of the moving waters, and it takes 3 to 4 weeks from egg development to adult. In summer, blackflies are very active, invading animals and occasionally causing them to panic, causing them to step on the ground and kick their legs. Cows sometimes roll in the mud or raise dust to drive away flies. The control method is to spray insecticides on the hatching sites of flies.
3. Midge
Midges are very small flying insects of the midge family, important of which are Cyborgs and Midges, which suck the blood of animals and humans and transmit one-day fever, bluetongue and other viral diseases. The larvae live mainly in swamps and can also survive in mud and stagnant pools. In addition, midges as carriers of the virus can cause hypersensitivity reactions in animals. Draining stagnant waterholes around cattle farms, or spraying stagnant water pools with oil or DDT insecticides, is effective at controlling midge hazards. Anthelmintics are effective in the short term, especially phosphorus benzodimethylates.
4. Horse flies and zebras
Horse fly is a type of fly. There are many species of cantharids, belonging to the genus Cantharid, The Mammoth and Aphids. The eggs are laid on plant leaves that grow in water or at the water's edge, and the larval and pupal stages are spent in water or mud. Adult flies are active during the summer months, especially when the weather is sweltering, and are often found on the ventral side and legs of cattle. Horse flies can be controlled by draining the water from the wetland or by treating stagnant pools with oil and insecticides. In addition, anthelmintics are used, which are effective but last only a few days, such as phthalemia hydrochloric acid and γdimethylaniline.
5. Houseflies
Common houseflies are distributed around the world and can cause irritability in livestock when active in large numbers and can transmit diseases. Houseflies can worsen wound infections, excrete some stomach contents and feces, stain food and cause infection, and easily transmit pathogens. The eggs are laid on decaying plants or feces, and the eggs hatch out of the larvae, which mature after about 10 days. During the warmer season, the entire life history of houseflies is 12 to 14 days. The control method is to remove feces and other maggot-prone organic matter at least once every 3 days. Collect flies and maggots with a flycatcher, spray buildings with insecticides, keep the environment clean, or spray with insecticides in places where there is a breeze. Insecticide impregnation of ear tags is not very effective for controlling houseflies.
6. Autumn housefly
The autumn housefly is a small fly, similar to but slightly larger, common in Europe, Asia and North America, and often gathers in flocks during the summer months, especially attacking cattle outdoors. Because the fly feeds on nostrils and eye secretions, it is often found in the nostrils and around the eyes of cattle, and fresh cow dung is its only breeding ground. Although organophosphorus agents and plastic ear tags impregnated with insecticides have a certain effect on the control of autumn houseflies, there is still no complete and systematic control method.
7. Head flies
The head fly belongs to the genus Pteropodium and is a nuisance type of fly. The fly has a grass-green abdomen and yellow wings. It does not bite animals, but feeds on exudates around the wound, causing local inflammation of the skin and mucous membranes. Headflies can irritate the body, worsen the wound, resulting in an enlarged wound ulcer surface, which can spread both summer mastitis and corneal conjunctivitis in cattle. Controlling head flies is difficult, usually using spray and impregnation. Plastic ear tags soaked in insecticides also have an effect.
8. Stable flies
The stable fly is similar in shape to the house fly, grayish white, and the stable fly has a sharp beak, which sucks the blood of the host for a living, which can cause severe irritation, and bites can cause bleeding from the wound. Stable flies lay eggs in feces and rotten hay or straw, and the warm and humid environment is conducive to the growth and survival of flies, which can affect the normal production performance of livestock when the fly appears in large quantities, and can cause hypersensitivity reactions in cattle anemia and forelimb skin. Large blisters appear at the site of the bite, which fuse to form bleeding ulcers. Control methods include frequent house changes and timely disposal of mat grass and feces. Livestock houses can be killed using ear tags soaked in insecticides or sprayed with a suitable spray.
