Cows do n’t feed, most of them are “Vampire Ranches” invading
The most terrifying killer in history, ordinary insecticides have no "agent" to apply
Recently, a number of pastures inquired about cows clustering and not eating, suspected of infestation by blood sucking pests like gadfly. Traditional pesticides are not effective, even imported pesticides with attractants are not effective. In order to find out more, the cattlemen went into the cowshed shirtless and found that the biting cow was a kind of blood-sucking flies that bite. What the hell is this? Today, I will introduce you to this "vampire" that is a great danger to pastures-stable sting flies.
The most blood-killing killer in history
More fierce than the invaders, the goal of the stable fly is to suck blood nakedly. Their adult worms are 5-10 mm long, grayish brown with brownish brown. They are mainly active in the daytime. They feed on the blood of livestock and occasionally human blood. After the temperature drops in autumn, they inhabit the sunny cowshed. Large ungulates are the main targets of stable sting flies, such as cattle and horses. First gather on the legs, then move to the rest. Unlike other blood-sucking insects, the saliva of stable sting flies does not contain anesthetics, so its bite can cause severe pain to cattle. In the absence of cattle and horse animal hosts, bloodthirsty targets are also directed at dogs and humans.
In addition to directly affecting the health and milk production of livestock, blood-sucking demon can also spread pathogens such as anthracnose and trypanosomiasis. Cows bitten by stable sting flies will exhibit abnormal behaviors such as clustering, non-feeding, non-drinking water, and non-rest, resulting in a reduction in milk production and weight loss of the cows, and losses to the pasture.
(Adult flies are 5-10mm long, with dark gray, black, yellowish brown and other colors, many types have metallic luster, and the whole body is covered with mane.)
