Almost everyone had to deal with fruit flies, most often they swarm around vegetable stores, warehouses, shops. Under natural conditions, fruit flies are found in gardens, often at the end of summer they fly from the street into an apartment and can cause trouble.

Where do Drosophila come from? If you leave a rotting apple in a bucket for a short time, after a few days a swarm of flies will fly around it, which can be very difficult to get rid of. Drosophila is widely used in scientific experiments, experiments in genetics are carried out on them, their demand in this area is explained by their short life cycle and availability.

Description

Drosophila is also called fruit flies, for a long time they have been living in close proximity to people, since each apartment has a trash can with waste.

Appearance, differences between individuals of different sex

Drosophila is small in size, the average length of an individual is 1.5-3 mm, the wings are longer than the body. The color of the eyes is red, which is noticeable only under a microscope. Insects are distinguished by a yellow-brown color and a pronounced sexual diformism: the body length of females is on average 2.5 mm, the body length of males is noticeably shorter, the back is darker.

A distinctive feature of the male is also considered to be pointed bristles, the female has a more rounded abdomen, the end is pointed, in the male the abdomen has a cylindrical shape, the end is blunt. In the female there are 8 developed tergites, in the male - only 6, 6 and 8 are fused, in 8 they are part of the reproductive system.

In the female, there are more chitinous plates on the ventral side, in males 1, 2, 7, and 8 sternites are not developed.

Important! Some of the differences between females and males vary depending on food and living conditions.

Habitat

Insects wide distributed in the south of Russia, in the northern part of the country they penetrate through vegetables and fruits. The species is distributed throughout the country, with the exception of the Far North, which is explained by low temperatures throughout the year.

The life span of fruit flies is at a temperature of 25 degrees ten days on average, at 18 degrees, the period increases threefold. Throughout her life, the female lays several hundred eggs, while much depends on the living conditions, temperature, stocking density, food conditions.

Larvae

Larvae are worm-shaped, hatch from eggs in just a day, the transformation period of the larva into an adult is ten days, which is why they can quickly populate the room in which they originated. The main source of food for the larvae are microorganisms that cause the processes of acetic acid fermentation, they live on the surface of the fruit.

Adults feed on rotting vegetables and fruits, juices, wine, tree sap, jam and various waste products.

Important! Fruit flies reproduce very quickly and can become a real problem if this happens in an apartment. In order to prevent their appearance, it is recommended to throw away garbage as often as possible, not to leave waste on the table, to get rid of rotten vegetables and fruits in time.

If this does not help, there are special chemical and mechanical means to combat them, many use insecticides, traps and folk recipes.

Views

There are more than a thousand species of fruit flies on the planet, the largest number is observed in tropical and subtropical climatic zones, about three hundred species are localized in Hawaii.

The most famous is Drosophilia melanogaster, a flightless fruit fly that is widespread in Russia.

This species is considered very important for research, and hearth flies have been used in science for several decades.

Important! Drosophila histrio, Drosophila trivittata, and Drosophila funebris are also known species.

The fruit fly feeds on fermented products, it is sensitive to sour odors and inhabits rooms in which rotting fruits, vegetables, and fermented drinks are stored. During her life, the female lays several hundred eggs, which explains the high reproduction rate of insects. There are more than a thousand varieties of Drosophila, with visual differences between males and females.
