Will there be parasites on the body of worms, and what bugs will parasitize on human skin

If the concept of parasites is expanded, many insects may be parasitized by parasitic mites and lie on the surface of the insect's body, I have photographed a lot of such **;

If it is a little bigger, insects can also be parasitized by insects, for example, many parasitic wasps will lay eggs in the bodies of other insects, and after the larvae of parasitic wasps hatch, they will eat meat in the body of that insect Usually, until the larvae of parasitic wasps do not need to eat meat anymore, they will pupate, and the parasitic insects will die (these are the so-called biological control, which are commonly used to control pests).

Some, such as cicadas, die in the fall because of parasites. In addition, insect parasites are one of the main biological control methods for controlling pests. For example, parasitic wasps such as wheat moth Xiaofeng and red-eyed bee lay their eggs on the larvae of moths; Kill pests by parasitism.

*Yes, worms may have parasites on their bodies**. For example, praying mantis often has nematode parasitism in their bodies.

Adult nematodes live in swamps, ponds, streams, ditches and other water bodies, male and female mate to lay eggs, and the larvae in the eggs hatch into insects (grasshoppers, crickets, cockroaches, beetles, etc.) to develop into larvae, insects enter the water, and the larvae leave the host to develop into adults in the water. Human digestive tract infections may be caused by contact with or drinking raw water, insects, fish and snails or food that contain larvae.

Please note that the above is just an example, not all insects have parasites, and you should avoid contact with untreated sewage and raw meat.

Snails refer to all terrestrial species of the class Gastropoda. In general, Western languages do not distinguish between aquatic snails and terrestrial snails, and in Chinese, snails only refer to terrestrial species, while snails in a broad sense also include giant shield slugs.

To correct it, it's a tick. 、

<> parasite is extremely fond of animals with dense fur, especially cattle, and can often be found under the neck and inside of the legs, and often gathers in herds, and is very difficult to remove. It is extremely common in rural areas such as Sichuan, Yunnan, and Guizhou.

Prevent tick bites.

1. To eliminate ticks on the body surface of domestic animals and in the barn, insecticides such as trichlorfon and dichlorvos can be sprayed. Houses should be ventilated and dry, cracks in walls should be filled, burrows should be sealed, and barns and poultry houses should be cleaned or sprayed with drugs to eliminate the breeding grounds of ticks.

2. Strengthen personal protection, enter the forest area or work in the field, wear long-sleeved shirts, tie belts, cuffs, trouser legs, tie a towel around the neck, apply ointment on the surface to prevent tick bites, take a bath and change clothes when you return from going out, and prevent ticks from being brought home.

In addition, it is summer, it is a good season for people to go out to travel, here I would like to remind everyone that when going to the wild, in addition to the above two points to pay attention to, do not go to undeveloped scenic spots, try not to go to dense forests and fields. This way we will avoid tick bites.

Bitten: Once bitten by a tick, do not pull it raw, forcibly pull it out, and do not crush it with your fingers. Alcohol, kerosene, or turpentine should be applied to the head of the tick, or a mosquito coil should be placed next to the tick to "anesthetize" the tick and let it loosen its mouth; Or thickcoat the head of the tick with liquid paraffin wax or glycerin to suffocate and loosen the mouth.
