Recently, the whole country has been heating up, and summer has quietly arrived. Pig farms, a large amount of piled up manure can be described as a paradise for flies. Flies are widely distributed around the world, they have a strong adaptability to the environment, female adult flies have a very sensitive sensing system, can accurately find the right temperature and humidity place to lay eggs, and larvae can find enough food once out of the eggs. When the sound of "hum, hum" bombards people's eardrums one after another, a war of annihilation flies has begun.
The appearance of flies in people's daily work and life has become increasingly intolerable. A fly, no matter how small it is, can cause a lot of trouble when it appears on some occasions.
Flies are an important vector for the spread of swine disease. Flies can transmit the pathogens of Japanese encephalitis, pseudorabies, highly pathogenic blue ear disease, swine fever, erythrocytic body disease, infectious meningitis, foot-and-mouth disease, porcine erysipelas infectious gastroenteritis, and swine dysentery. If the pig farm fly control work is not done well, no matter how strict the epidemic prevention of the pig farm is, how thorough the sanitation and disinfection are, the flies will still spread the above pathogens everywhere.
The fly's ability to complete its life cycle depends heavily on climatic conditions. When the temperature is below 15 ° C or above 45 ° C, and the humidity is less than 60% or above 80%, it can well inhibit the growth of flies. Of the entire fly population, 80% are developing and only 20% are adult flies. Therefore, the extinction of flies in April allows the flies to be controlled in the larval stage.
Properly reduce the temperature of the pig house, the flies will feel "cold" and are more willing to go outside the house.
In order not to affect the normal production of pigs, it is possible to control the number of eggs. The eggs of mosquitoes and flies generally reside in pigs and in pig droppings. Cipromazine is an efficient and low-toxic insecticidal agent that is effective in killing larvae of diptera insects. Feed addition allows flies to be eliminated before they become adults, which has a good effect on many pig farms.
Fly-killing tools such as fly-killing lamps, fly-catching cages, and sticky fly stickers can be placed in areas where mosquitoes and flies are active, but traditional methods have limitations, are less flexible, and require regular cleaning and replacement.
If you have missed the best time to kill flies, there are already flies in the pig house, and you can spray a permethrin solution on the walls and corners of the pig house, which can effectively kill the flies attached to the wall. Spraying points: Do not spray directly on the pigs to avoid poisoning.
Doing a good job in the exorcism of flies can effectively reduce the spread of diseases and improve economic benefits significantly.
