Why can the nematode control insects from diving, but they live in the human body all the time?

Wire worms do not live in the human body all the time, and the parasitism of the iron worm has a process from entering the human body to leaving the human body.

The larvae of the nematode begin to develop after entering the human body, and will swim in the human body, and when they mature, they will look for the breaking point, generally in the lower limbs of the human body, at this time the lower limbs of the human body will appear a broken bag, accompanied by a severe burning pain. In order to relieve the pain, the person will soak the leg in cool water, and then the nematode will burrow out of the broken ** into the water, and reproduce, waiting for other animals to inadvertently eat the larvae in the water, starting a new parasitic cycle.

The nematode controls the insect to dive, which does not mean that it controls the insect's brain, but also uses the burning pain to make the insect instinctively find cool water to relieve the pain, which seems to be the insect diving under the control of the nematode.

For the first time, the user inputs that in our usual understanding, the concept of "image" means something with a perceptible nature, and to say that one thing is an image of another thing is to say that one thing reproduces some sensible experiential qualities of another thing, or that there is some similarity in the nature of experience between something as an image and something as a prototype. For example, a landscape painting is a reproduction of its prototype - the real landscape, and what is reproduced is the empirical characteristics of the landscape, such as shape, color, orientation, and size ratio. However, when Wittgenstein says that "propositions are images of reality, and propositions are models of reality that we imagine", he does not use the concept of "images" in the sense of this "same perceptible property".

Since propositions are made up of words, there is no empirical similarity or resemblance between these words and things in reality, and a proposition composed of words cannot have any of the same perceptible properties as a fact made of things. Therefore, the linguistic image that Wittgenstein refers to is essentially an "image" in the abstract sense rather than in the empirical sense, and it refers only to a logical structure diagram. Although a proposition cannot have any empirical content in common with a fact, the logical structure of a proposition is consistent with the logical structure that constitutes a fact.

To say that a proposition or language is an image of a fact is to say that a proposition reproduces or depicts the logical structure of the real world with its own logical structure. It can be seen that a proposition is still an "image", but it is not an image with a perceptible empirical nature as its content, but an image with abstract logical structures as its content.

The nematode is also known as the hair-shaped snake, the nematode has a slender body, horsehair-like, up to 1 meter long, distributed in the northern and southern provinces in China, and widely distributed in all parts of the world abroad.

The eggs laid by the nematode female hatch larvae in the water, and after being swallowed by large arthropods, such as praying mantises and locusts, the larvae can continue to develop in these arthropods until they leave the host after maturity, live freely in the water, and mate and lay eggs, so the nematode can infect the human body through the water source, causing people to suffer from nematoasis.

Wire worms may live in the human body and can continue to develop and survive for several years.

When the nematode parasitizes in the human body, it can cause indigestion, abdominal pain, frequent urination, urgency, etc., therefore, the key to preventing infection with the nematode is not to drink dirty water, do not eat raw insects, fish, snails, and other foods, and avoid oral contact with dirty water.

Wire worms can live in humans.

The nematode is also known as the hair-shaped snake, also known as the capillary nematode or Gordius nematode, and the soil is called the copper wire snake or Tencel. It belongs to the phylum Nematozoa and is the general name for worms of the class Elematode. There are 250 to 300 species of insects related to medicine, including the order Nematodes, Nematodes, Chordodes, Paragordius and Parachordodes.

The body of the nematode is elongated, horse-haired, and can reach up to 1 meter long. Adults live freely in seawater or freshwater, and the larvae parasitize the arthropods. It is distributed in the northern and southern provinces in China, and is widely distributed in all parts of the world.

It can infect the human body through water sources and cause nematoasis. In scientific research, it is often used as experimental material for zoology.

Habits of nematodes

Adults inhabit rivers, ponds and ditches, and the eggs laid by females hatch larvae in the water, which are eaten by insects or humans and live as parasitists. When the worm is ingested by large arthropods such as praying mantises, locusts, etc., the larvae continue to develop in these arthropods and gradually control the behavior of the host. When the larvae grow into adults, they control the host to find water and drown the host before burrowing out of the host.

Humans can easily drink these nematode larvae in pools and unclean water, and there is a certain chance of contracting nematosis after drinking. This disease causes infection and inflammation of the body, so the water from the pond and unclean water cannot be drunk casually. The larvae in the arthropod will induce the parasite to seek water, so it is not recommended to drink it when the water source contains arthropod carcasses.
