How can you tell if a praying mantis has nematoasis? Thank you! Experts, please!!

Hello landlord! Clematodes are living things, not diseases. If the praying mantis is parasitized by a nematode, then its belly will be unusually large!!

And often go to places where there is water. The praying mantis does not die from the nematode breaking out of its body, but the nematode will take it out when the mantis dies. As long as the mantis's belly is immersed in water, the nematode will come out because the nematode has to reproduce in the water.

But if you wait a while and still don't have it, just pick up the praying mantis! Because praying mantis breathes on its stomach, it will die if it is soaked in water for too long!

The parasitic praying mantis will have a particularly large belly, and when the nematode matures, it will drive the praying mantis to the water's edge, and then burst out of the belly, and the praying mantis will die of injury and cannot live.

It is not so much the control behavior as the major defects in the nervous system of insects and even arthropods with the exception of crustaceans that lead to the control of the praying mantis, which is parasitized by the nematodes. The same thing you don't put on other animals doesn't happen.

The nervous system of insects is actually made up of ganglia that perform a series of motor tasks relatively independently of each other. In the long evolution, for the relatively evolved praying mantis, he has completed the merger of 6x2=12 ganglia in the head, and at the same time, the ganglia in the tail are basically completely wasted, and the ganglia in the abdomen are closest to the head, so the head only provides the necessary movement commands.

So have you heard of any flies that fell out of their heads and that he was still alive? That's evidence that the insect's nerves responsible for abdominal movements can be easily disconnected from the nerves in the head.

Because of this, the nematode, which is parasitic on the body of the praying mantis and is not at all in the head, naturally easily blocks the connection between the nerve of the abdominal tube movement and the head. For other higher animals, if you want to control your behavior, you have to manipulate your brain directly.

At the same time, the nematode must also retain another signal from the head to the body, "phototaxis", so as to achieve control over the direction of the body, in fact, the praying mantis crawls to the water because of the reflection of the water surface, not other factors.

If it is not reflected on the surface of the water, but on the road, a large number of praying mantis parasitized by the nematode can still gather.

In addition, the temperature, sound, etc. have been varied to confirm that it will not cause the praying mantis to throw water.

The principle of iron nematode control mantis is that iron nematode can secrete a neurohormone, which affects the nervous system, causing its disorder, making the host feel that he is seriously dehydrated, so the host will go to find water, and the mantis will drown if it looks for water and jumps into the water. 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. Species related to medicine belong to the order of nematodes, nematodes, nematodes and stingworms, etc., and the nematodes are slender, horsehair-like, and up to 1 meter long. Adults live freely in seawater or freshwater, and the larvae parasitize the arthropods.

The habits of the nematodeAdults 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 this insect is swallowed by large arthropods such as praying mantis, locusts, etc., the larvae continue to develop in these arthropods, and will gradually control the behavior of the host.

Put the lower body of the praying mantis in salt water, and if there is a nematode, the nematode will come out. The praying mantis is not impulsive when passing by the water, but walks slowly over it, which indicates that the praying mantis is not infected with nematodes. At.

In the late summer of August and September, a drowned praying mantis is found by the pool, which is the masterpiece of the nematode. <1. Put the lower body of the praying mantis into salt water, and if there is a nematode, the nematode will come out.
