Why are there white flies? Why are there so many flies?

White flies.

It is flies that have albinism.

This should belong to the phenomenon of albinism in animals, and there are many animals in nature that can have albinism, such as white leopards.

Tiger, etc. The phenomenon of albinism in animals is only that the body is white, and other manifestations are normal.

For species in nature, the morphological structure of the members of the same species is very similar to each other, but in higher animals, there will occasionally be individuals who are different from the same species, especially in the body color such as feather or coat color and all other individuals of the same species are obviously different, but there is no difference between them and other individuals of the same species in their internal structure and various organs, and they also have the ability to reproduce offspring. Individuals with this abnormal body color are generally white in color, and all are referred to as albino animals.

It is said that Hubei Shennongjia.

In 1987, a white tortoise was found with a white body, only bright red eyes, and a transparent neck, resembling a carved work of art.

The ways in which genes affect an animal's body color are complex. It is mainly to control the activity of enzymes, through enzymes to control the biochemical reaction process in the body, and finally determine the morphology of the animal. In the body of normal animals, some phenylalanine.

Involved in the proteins that make up the animal body, other phenylalanine is converted into tyrosine, which is finally formed by the action of tyrosinase.

However, due to the lack of tyrosinase in albino animals, melanin cannot be synthesized, resulting in albinism.

1. There are many flies in the house, generally there is extruded garbage in the house, and the squeezed garbage in the house will attract flies to a large extent.

2. The food in the room is rotten, and many people are reluctant to pour the leftovers after eating, and then forget these leftovers, which eventually leads to rot and thus attracts flies.

3. Windows are often opened, and many people open windows for ventilation, but when the windows are often opened, they will also attract flies.

4. The house is a basement, because flies like a cool environment, if the house is a basement, it will greatly attract flies due to environmental problems.

5. The house is close to the toilet, and most of the rental houses have their own toilets, although this is much more convenient, but it will also cause too many flies in the house.

6. There is moisture in the house, and if the house is too humid, this environment will also attract a lot of flies.

The white bugs in the stomach of the flies are the eggs of the flies. Flies have amazing fecundity. It has been observed that houseflies in the laboratory lay about 100 eggs per batch, and a female fly can lay 10 20 batches of eggs in her lifetime, with a total of 600-1000 eggs.

The peak of spawning is at 17:00 to 19:00 every day.

The length of the pre-oviposition period (i.e. the time from emergence, to the first oviposition) of female flies is closely related to the ambient temperature: an average of 9 days at 15 o'clock, only a few days at 35 o'clock, and no eggs at 15 ovitable. After mating, female flies often crawl into breeding crevices such as human and animal feces, and extend out of the ovipositor tube to lay eggs deep in the breeding organism, so that the eggs can be fully protected.

Yellow dung flies are 5 to 11 mm long.

Male flies are bright golden yellow with orange-yellow hairs on their forefeet. Female flies are darker in color, greenish-brown in color, and do not have brightly colored hairs on their forefeet.

Drosophilidae (scientific name: drosophilidae) is a family of Drosophila of the order Diptera that is distributed all over the world and spends the winter in human homes. Some species of fruit flies live on rotting fruits, while others live on fungal or fleshy flowers.

It is small, 3 4 mm in length; The body of the insect is mostly yellow-brown, and some are black; There are a pair of large and mostly bright red compound eyes on the head, three pairs of eye-edge bristles on the inside of the two compound eyes, the back of the compound eyes is slightly raised, forming a monocular triangle, and there is a pair of monocular bristles under the front and bottom of the three monocephalic eyes.

Summary. Hello, the big white fly is a kind of fruit fly, I will send you **, you can take a look.
