What parasites do spiders have? What kind of creatures do spiders belong to?

It's not uncommon to have spiders in the city pet industry now. Compared with cats and dogs, spiders are relatively cheap and easy to keep ornamental pets. But animals that can breathe can get sick, and owners should always pay attention to the health of their pet spiders.

1. Wasting.

When you notice that the surface of the spider's body is becoming dull and the epidermis is starting to dry and yellow, it is likely that you have developed wasting. This condition is generally caused by spiders not eating well, and long-term starvation leads to malnutrition.

2. Enteritis.

Contrary to wasting, this is eating too much. The owner keeps feeding the spider, or the food temperature is too low when feeding, which will cause the spider to have abdominal distension and abdominal pain, and over time it will form enteritis.

3. Hemiplegia.

Spiders do not have high requirements for the environment, but when the temperature is too high, especially in summer, high temperature and humidity, the spider cage is too far away from the vent, so that the spider is close to heat stroke, and the legs and feet are paralyzed by nerves, and they will not be able to move half of their bodies.

4. Constipation. Constipation is most likely caused by not drinking water. In addition to eating, spiders also need water. If the owner blindly feeds the spider but does not give it water, the water in the food will not be able to supply the spider with the water it needs.

5. Black rot.

If you don't eat or move, your spirit will decline, and a black putrefactive ulcer lesion will appear in your abdomen, which is the manifestation of spider black rot. The reason for this is that the water and food are not fresh, and spiders will be infected with black rot if they eat food with germs, which can lead to death.

6. Mold disease.

Especially in the south, the high temperature and humidity in summer can easily cause the body surface of spiders to be invaded by bacteria. The joints of the spider are getting stiffer and the body is getting more and more damp, and the bacteria like to survive and reproduce in this environment, which makes the spider mildew.

7. Parasites.

Parasites are arguably the most disgusting disease of spiders. It's fine if it's a small bug, but the rampant parasite will wriggle around the spider's body and look very disgusting. Not to mention the rest of the spiders, they may also carry other viruses, causing multiple infections and threatening the lives of spiders.

1. Mites are more common.

This kind of insect will be born in a poor breeding environment.

2. In addition, some nematodes may also infect spiders.

3. Parasites on the raised spiders.

Very few. So few that it's almost invisible.

The way spiders live and feast can be divided into two main categories. That is, the nomadic type and the sedentary type. Safari type spiders, spiders that hunt everywhere, hunt, have no fixed residence, do not build webs, do not burrow, and do not build nests. There are scaly arachnidae, ursoaradae and most tarantulas.

Sedentary: some build nets, some dig holes, and some build nests as fixed dwellings. Such as wall money, stone-like spiders, etc. Spiders seem to be polite, and those who live independently keep a certain distance from each other and do not invade each other.

Compared to ordinary insects, spiders are long-lived, most spiders complete a life cycle, generally 8 months to 2 years, and male spiders are short-lived and die soon after mating. Others such as water spiders and cunning spiders can live for 18 months, burrowing tarantulas can live for 2 years, cancer spiders can live for more than 2 years, and birdcatcher spiders can live for up to 20 to 30 years.

All spiders live by the use of silk, silk secreted by the silk gland cells, in the gland cavity is a viscous liquid, through the spinning tube out, when it encounters air quickly condensed into a filament, the specific gravity of the silk is, strong and elastic.

Cave spiders are inside their webs during the day and at the entrance of their burrows at night, waiting for opportunities to hunt or go out to forage. The Xiongxiang wide spider digs a shallow pit under the clods, the burrowing tarantula digs a vertical deep hole in the ground, and the dancing spider also adds a trap at the entrance of the hole. This type of flap is made up of multiple layers of filament.

The hole of the spider is up to 1 meter deep, the spider is small, poisonous, and dies in four minutes after biting the burrowing hare.

2. Predatory habits of spiders:

Spiders feed on insects, other spiders, myriapods, and some spiders also feed on small animals. Jumping spiders have good eyesight and can dive within 30 centimeters to catch their prey and pounce on them. Crab spiders wait for their prey on flowers that are similar to Okiki's body color.

Spiders burrowing in the earth build burrows lined with silk, and the entrance of the burrow has a trap that opens at night to prey on insects that pass through the hole. funnel spiders weave funnel webs, and insects fall into the nets to cause vibration; The spider itself resides in a filament tube with a narrow end that leads into a plant or a crevice in a rock.

Spiders are poisonous, but there are very few species that can cause harm to people, and friends who often watch "Animal World" know that the average domestic spider is very small in size and has a limited amount of poison, which is insignificant to us and will not cause harm to life. If you are bitten by a house spider, **red, swollen or rash, please disinfect with alcohol or rub some toilet water.

Spiders, this ancient creature, have been on Earth for 400 million years, 150 million years before the dinosaurs. Over the course of their long evolution, spiders have developed a strong ability to adapt to their environment, and they are distributed in water, land, and air.

Spider silk, a silk protein with ultra-high strength elasticity and toughness, is an ideal material for making defense equipment such as body armor and parachutes. Spiders don't need any measuring tools to weave perfectly shaped webs: at the same angles and at equal intervals, it's a miracle of nature!

When the flying insect hits the web, the spider crawls over, spews out sticky silk to tie up the prey, anesthetizes it with fangs, and spits out the digestive juices on the food for external digestion. After the prey tissue has melted into liquid, it can be sucked in a big gulp. The food is digested externally by spitting out the digestive juices, and then inhaling the liquefied food.

Spiders have the ability to analyze quickly, and they can quickly catch any insect attack, even the slightest movement, and immediately distinguish friend from foe. The body of a spider is divided into two parts, thorax and abdomen, whereas the body of an insect is three. So, spiders belong to small animals, not insects.

There are an estimated 1.7 million species of spiders in the world.

Benefits of spiders.

Spiders only eat insects and never harm plants, so they are natural enemies of many pests. The lifespan of spiders, large spiders can reach 3 to 5 years. And spiders are very reproductive.

Experiments have shown that in a rice field with only about 1,000 spiders per acre, after 1 to 2 months, it can reach 5 to 60,000!

Spiders are very resistant to hunger. After you are full, you can go without food for more than ten days, dozens of days, or even dozens of months. They are also very hardy and will come out as long as the temperature is above 4 degrees.

If it is hot, it will avoid the shade, and if it is cold, it will be dormant. Unlike other insects, they do not lie dormant during the winter months.

Therefore, agriculture and forestry can achieve good results by using spiders to control insects. <>
