Description and photos of larvae and eggs of flies

Larvae of flies are extremely mobile white worms. They do not have legs, but move with the help of special hooks. Many females lay their eggs, but there are also viviparous flies. Synanthropic is well known to man. housefly, which is practically unable to live in the wild, meat, carrion or cadaver. The larvae of these species are similar in appearance, but they differ somewhat in their habitat and lifestyle.

Female fertility

Flies acquire the ability to fertilize the day after their birth. Young females lay about 70 eggs at a time, and more mature individuals - up to 120 eggs. The eggs of the flies are oval, off-white in color, no larger than 1 mm in size. They are always in heaps. A photo of the eggs of the flies can be seen below.

Flies on stage adults live from 14 days to 2 months depending on climatic conditions. During his life he manages to lay about 2 thousand eggs. Begin to show activity in the early spring, when the air temperature rises to +10 degrees Celsius. At the end of September, October, with a decrease in climatic parameters, the insect hibernates. Flies, larvae, pupae overwinter.

On a note!

Household habitual flies lay eggs in feces, rotting plants, vegetables, in order to immediately provide the larvae with food after birth. A carrion fly, it is also a meat fly, is viviparous. Reproduces in the same large number of larvae of the first age, about 1 mm in size. Baby Development Medium meat flies - dead tissue of animals, humans. Some larvae are predators, eat their own kind, grasshoppers, snails, or live under the skin of a person or animal, causing terrible diseases - myiasis.

Larval development cycle

After fertilization, eggs form for several days inside the female. In viviparous flies, this process is always 2-3 days longer. After laying in a favorable environment, the worms are able to hatch after 2 days. Shelving begins in late March, lasts until mid-autumn.

On a note!

Larvae of flies are called maggots. The term was given to unpleasant creatures due to its rapid growth, similar to a yeast dough called dough. Maggots move quickly, constantly feed, grow every day. Over 10 days of their active development, the larvae increase in size from 1 mm to 13 mm.

Outwardly, the maggot looks like a worm. The color is off-white or yellowish. It has no legs, no separation of the head. On the one hand, the body is pointed, in this part the oral apparatus is located, on the other hand, it is cut off. They are moved using special hooks, initially they are fixed, then they are pulled up.

Depending on temperature conditions, larvae develop from 10 days to 20. During this time, about 4 links pass. Periodically dump the old chitinous cover, increase in size. A photo of a fly larva is presented below.

In the last stage, pupation occurs. Maggots look for a dry, cool place or burrow into the soil. The body hardens, becomes immovable. Within three days, an adult fly appears, ready for fertilization. The entire life cycle of an insect from an egg to an adult takes 15 days on average. Flies of a new generation hatch for the entire warm season up to 20 times.

Feeding maggots

Synanthropic insects feed on decaying organics, sour juices. Food source they are served by human food, crumbs, garbage in a trash can, feces, rotting vegetables, fruits, plants. The same food is needed for the larvae.

Meat flies develop on the dead rotting tissues of animals, humans, as well as in feces, manure, pus, and garbage cans. Larvae help decompose corpses, thereby bringing extreme benefits. At the last stage of their development, they dig into the soil, pupate.

The larvae of flies do not have a digestive system; they absorb already digested food. To do this, they initially emit a caustic, aggressive chemical substance that dissolves any organic tissue, and then they absorb the ready-made food.

Interesting!

Maggots live in an extremely dangerous environment that is teeming with pathogens. They themselves do not get sick, they produce the strongest antibiotic - seraticin, to which pathogens are not able to develop immunity. Larvae stop rotting tissues, therefore used in medicine for treating poorly healing wounds. Maggots are grown specifically under sterile conditions.

Benefit and harm

They are trying to get rid of the larvae of flies in every possible way, they are also specially grown in artificially created conditions. Maggots act as food for other animals, fish. They are used in the fishing industry as a bait.

In the wild, the larvae perform an important function - they decompose corpses, which is of great benefit. The behavior and development of maggots is well studied, therefore, according to their age, forensic pathologists determine the date of death of a person.

Despite the fact that the habitat of maggots is extremely aggressive, pathogenic, they are not the spreading agents of the infection. Adults do this - flies, clinging a different infection to itself on the legs, body. The most common diseases are intestinal infections, the most dangerous are leprosy and anthrax.

The larvae of some flies can live in the body of an animal, even a person, causing a terrible disease - myiasis. Penetrate into the body in the form of eggs through open wounds, settle under the skinforming tubercles. A close inspection reveals movement inside. Some larvae of flies as they develop can migrate, settling in the eye, ear, internal organs. To remove them requires surgical intervention.

On a note!

There are no dangerous maggots in our area. But there are times when horseflies lay their eggs in an open wound, and undergo several stages of development under the skin. There were cases when they lived larvae of flies in the ear. Dangerous to the eye myiasis, a person risks completely blind. Not always after a successful operation to extract the worm, the visual organ is restored.

Maggot control

Extermination of larvae of flies in most cases, carried out by preventive methods to prevent the completion of the full development cycle. The following methods actively influence flies to reduce the number of eggs:

• Indoors, you can get rid of larvae of flies with sterility. Dispose of garbage in a timely manner, discard rotten fruits, vegetables, do not leave crumbs on tables, maintain cleanliness in the toilet. It is recommended to install mosquito nets on windows and doors.
• To get rid of adults, larvae use insecticides. In most cases, use sprays, aerosols. Effective, affordable remedy - Karbofos, Dichlorvos, Raptor, Raid, Clean house, Agita. Death occurs within 2 hours.
• The area where garbage cans are installed, concreted, put asphalt.
• Promptly remove fresh poultry, animal, fish meat into the freezer. Eggs die at temperatures below +8 degrees Celsius. Adult flies are instantly killed by -12 degrees Celsius.At +10, females stop laying eggs.
• Wash hands thoroughly before eating, process foods, and disinfect wounds. Such measures resist the ingestion of eggs in the body, prevent intestinal diseases, miases.

For capturing insects using sticky traps, poisonous baits, special lamps.
