Insects of the order Diptera anneus can be called flies. China has found more than 400 species, more than 40 kinds of human body related, a fly can carry a variety of germs, the number of germs carried can be as high as millions to tens of millions, flies are one of the four major pests in the city. Therefore, how to actively improve the method of controlling flies has become an important issue in public health.
<h1 class= "pgc-h-arrow-right" > the secret of the fly</h1>
Fly eggs are mostly oblong in shape and are often clustered into clumps. Larvae are commonly known as sisters, footless, and their cephaopharyngeal bone, posterior valve sheet, posterior valve fissure, and abdominal end process are commonly used features in classification and identification. Pupae are caudal pupae. Eggs hatch in about a day in the summer, but there are also direct larvae, such as the fly. The larvae are generally 3 years old, and the old mature larvae pupate in the surface layer of the breeding ground or crawl into the loose and dry soil nearby. Adults can mate about 2 days after feathering and lay eggs a few days after mating.

01# Houseflies
The activity of houseflies is greatly affected by temperature: it is more active at above 20 °C, it is most active at 30-35 °C, and it is stationary at 35-40 °C.
When the temperature rises to 30 ° C, the houseflies like to stay in a relatively shady place, and when the temperature drops, they invade the room, often perching on the ceiling, electric light hanging line, window frame and so on. It is also often concentrated in stables, and is active on livestock or around manure and garbage heaps.
02# Stable rotten fly
The suitable temperature for the activity of the stable rotting fly is about 20 °C. The fly is active indoors and outdoors, and the outdoors are mainly concentrated in farmers' markets, campuses, parks, pigsty, cattle, horse sheds and other places, and indoors are often concentrated in dormitories, restaurants and other places.
03# Big-headed gold fly
The large-headed golden fly likes outdoor activities, the population number and activity season in China are very different from the north and south, the more south, the larger the population, the longer the activity season; the more north, the smaller the population, the shorter the activity season, and its peak season is mainly in the middle of summer. It is often active around toilets, wet markets, and garbage dumps, and can be used indoors during peak seasons. The larvae mainly breed in rare human feces.
<h1 class="pgc-h-arrow-right" > food for flies</h1>
Omnivorous food, its food range is very wide, including warm-blooded animal excrement, secretions, human food, kitchen waste and plant juice. Water has a greater impact on the survival of houseflies, and some liquid and moist surfaces can lure houseflies due to frequent drinking of water.
It likes to eat human and animal manure, but also feeds on human food, household garbage, plant juice, etc.
Adult flies like to eat fruits or fishy substances, and also like to eat feces.
Flies control
01 Control of fly breeding environment
Improving sanitation, eliminating or reducing the breeding sites of fly maggots, and controlling and managing breeding sites are important links in the eradication of flies. It is mainly used for manure (including livestock manure) treatment and garbage removal pretreatment. It is necessary to strengthen health supervision over industries that are prone to breeding flies, such as meat factories and sauce factories, do a good job in hygiene, and remove and control breeding sites.
02 Install fly prevention facilities
Fly prevention facilities mainly include screen windows, screen doors, yarn covers, glass rooms and glass cabinets, glue curtains and wind curtain machines. In the catering industry, food processing plants, beverage factories, food sales industry, cabinets selling cooked food, pastries, etc. should be set up perfect anti-fly facilities, enterprises, institutions, institutions and other units of the kitchen, restaurant, deli operation room, cold meat room, processing direct import food workshops should also be set up anti-fly facilities.
03 Adult fly control
The insecticide with effective effect will be sprayed, smeared, painted and applied uniformly to the surface of the place where flies like to crawl or inhabit, and the contact killing effect will be used to kill the flies. This method is often used to treat places where flies inhabit and feed, especially on surfaces where they stay at night. When applying the drug, the drug concentration should be adjusted according to the water absorption performance of the surface of the treated object to ensure the effective dose per unit area.
