Why do they always swim up and down the water?

Scientists conducted experiments on underground house mosquitoes. These mosquitoes maintain a strong mobility even in winter, and their larvae are resistant to insecticides. The researchers put the larvae of the subterranean mosquito into a glass container and added copper coins to the container, and soon the larvae of the subterranean mosquito also died.

Scientists have detected copper ions in water that has been added to copper coins. The maximum concentration of copper ions is only 1ppm, which is harmless to humans. Scientists believe that copper is more resistant to bacteria when it is not rusting, so you can try to use copper coins to repel mosquitoes, but it is better to use clean new coins.

If there are no mosquitoes, then there will be no mosquitoes, and if there are no mosquitoes, then there will be no mosquitoes.

For breathing.

孑孓 (jiejue) invertebrates, insects, larvae of the genus Diptera. It is hatched from eggs laid by female mosquitoes in fresh water. The body is elongated and dark brown in color, swims vertically up and down in the water, feeds on bacteria and unicellular algae in the water, and breathes the atmosphere.

For example, the tail end of Culex mosquito (house mosquito) has a long breathing tube, and the tube end is the opening of the respirator, and when breathing, the body is at an angle to the water surface, so that the breathing tube is perpendicular to the water surface; Anopheles mosquitoes (Anopheles mosquitoes) do not have a breathing tube, and the respirator at the tail end of the mosquito opens on the surface of the body, and the body is parallel to the surface of the water when breathing. After 4 molts, they develop into pupae, and then feather into adult mosquitoes.

Answer: These two words refer to a kind of thing, which is explained in the dictionary as the larvae of mosquitoes, that is, mosquitoes in childhood. Because it is a larva when it is in the water, when it develops into a pupa after molting, it grows into an adult mosquito from the pupa and then feathers, and the mosquito with limbs cannot survive in the water, and it is also because of the living habits of the widow so it must surface, so that it can grow and survive.

This allows you to breathe air through your snorkel, which is why sprinkling a layer of gasoline on the surface of the water can kill the baby.

Oxygen! It can't breathe with its gills like a fish!

It needs oxygen, and it doesn't have gills.

Because it is a mosquito larvae, it has no gills and goes to the surface of the water to breathe!

Mosquito larvae, once I put a basin of water on the balcony, and then I forgot about it, and after a few days there were a lot of these mosquito larvae, you can spray insecticides to kill them, and if you don't kill them, they will become worms and come to suck your blood.

It is the larvae of mosquitoes that pour out the dirty water, scald them to death with boiling water, and then refill the vase with fresh water. Change the water frequently in the future, otherwise, mosquitoes may still visit.

It is a proliferation of dirty water bacteria, and it is recommended to keep a few goldfish in it, and the goldfish can eat the bugs.

It looks like a child. 孑孓 ([jié jué] is the larva of a mosquito, an intermediate stage in which a mosquito grows from egg to pupa, hatched from mosquito eggs in water, lives in water, feeds on bacteria and unicellular algae in the water, but it breathes air.

There is a long snorkel at the end of the tube, and the end of the tube is the opening of the respirator. When breathing, the body is at an angle to the surface of the water so that the breathing tube is perpendicular to the surface of the water and sticks out of the water, breathing air directly. If frightened, dive underwater.

The meaning of 孑孓 and 孒 both refer to the larvae of mosquitoes.

1. 孑孓 (jiéjué).

The larvae of mosquitoes are the intermediate stage of mosquito growth from eggs to pupa, hatched by mosquito eggs in water, with a slender body, a wider chest than the head or abdomen, and a bent and stretched body when swimming, commonly known as a heel worm. It has a slender, dark brown body and swims vertically up and down in the water, feeding on bacteria and single-celled algae in the water and breathing air.

Interpretation: The little red heel worm in the well is the larvae of mosquitoes, called Xiaoxiao.

Habits: 孑孓 (jiéjué) is hatched from the eggs laid by female mosquitoes in fresh water. When breathing, the body is at an angle to the surface of the water so that the breathing tube is perpendicular to the surface of the water; Anopheles mosquitoes (Anopheles mosquitoes) do not have a breathing tube; The respirator at the tail end of the body is open to the surface of the body, and the body is parallel to the surface of the water when breathing; If frightened, dive underwater. After 3 molts, the pupae develop into a pupa that can still be moved at the beginning, but is basically immobile when it is feathered, and then feathers into an adult mosquito.
