CATDOLL : CATDOLL: Why do centipedes stink?

1. Why do centipedes stink?

【Species name】 Centipede

【Also known as】 Centipede, dragon, millipede

【Scientific name】Scolopendra subspinipes

【English name】 Scolopendra

【Classification】 Myriapoda, Psittacidae

The first pair of legs are hook-shaped and sharp, with poison gland openings at the hook ends, generally called palatine teeth, claws or poison limbs, etc., which can discharge poison. After being bitten by a centipede, its poison glands secrete a large amount of venom, which is injected into the subcutaneous tissue of the bitten person through the poison gland openings of the palatine teeth, causing poisoning. It is generally between 1.5 mm and 34 mm long.

The medicinal centipede is a large lipped myriapod with only 21 pairs of legs and one pair of maxillipeds; the "money string" is also a centipede with only 15 pairs of legs and one pair of maxillipeds; the "stone centipede" also has only 15 pairs of legs. Some centipedes have many and short legs, with 35 or 45 pairs, and the largest number reaches 173 pairs.

Medicinal name: Centipede

Other names: Tianlong, Baijiao, Wugong, Qianchuanzi

Origin: Centipede is a long, flat arthropod carnivore with a pair of legs on each segment. It originated in the Silurian Period and there are still 2,800 species alive today. Like arthropods, it is famous for its multi-arthropod organisms.

Centipede, also known as Tianlong, Baizu, and Centipede, is the dried body of the Giant Scolopendra subspinata of the Scolopendra family. This product is pungent, warm, and poisonous. It has the effects of dispelling wind and calming the nerves, detoxifying and dispersing knots, and dredging meridians and relieving pain. It is a traditional animal product medicinal material in my country. Centipede is mainly produced in Jiangsu, Zhejiang, Hubei, Hunan, Shaanxi, Henan, Guangxi and other provinces and regions. It is currently in the season for catching and processing. The catching method is introduced as follows:

Living habits Centipedes like to live in hilly areas and sandy areas. During the day, they lurk in the cracks of bricks and stones, at the foot of the wall, and in dark corners of piles of leaves, weeds, and rotten wood. They come out at night to look for caterpillars, spiders, cockroaches, etc. Generally, when the weather turns cold in October, they drill into the soil on the leeward and sunny slopes, lurk in the soil about 12 cm deep from the ground to hibernate until the next year after the Waking of Insects (early March), and then move around to look for food as the weather warms up.

Capture Method: Centipedes are usually captured in late spring and early summer, especially between the Waking of Insects and the Qingming Festival. If it is after the Beginning of Summer, most females will hide in secluded places to lay eggs and molt, making it difficult to capture them. In addition, after the Beginning of Summer, there will be more rain, and the captured centipedes will be difficult to dry, and they will easily become infested with insects and rot, and the meat will be thin and of poor quality.

To capture centipedes, you can do it according to their activity characteristics. The methods are as follows: ① Centipedes are carnivorous animals, and they forage for food from 8 pm to 3 am the next day. At this time, you can use a flashlight or a windproof oil lamp to search for centipedes in their hiding places. If you find centipedes, pick them up with bamboo clips or tweezers and put them in the prepared bamboo basket or cloth bag. ② Choose a place where centipedes hide, use a pointed hoe or a nail rake to dig the soil layer, lift up stones and bricks, and catch centipedes using the above methods. ③ Dig a nest to trap. In the habitat where centipedes often move, choose a damp mountain area around the beginning of spring, dig a "cross" shaped long pit, 1 to 2 meters long, 0.5 meters wide, and 15 to 20 cm deep, put chicken feathers, miscellaneous bones, horse manure or bird droppings and some rotten grass in it, cover it with branches, soil or bricks and tiles, and lure centipedes to crawl into the gaps. Check the next morning, and if there are centipedes in the pit, you can catch them.

Centipedes have venom. If you are stung by one accidentally during the capture process, you should squeeze the sting with your hands in time to prevent the venom from spreading to the subcutaneous tissue. Then apply 3% ammonia water or 5% to 10% baking soda water to the sting as soon as possible; or mash fresh mulberry leaves, dandelion leaves or onions and apply them on the sting.

Processing technology: The captured live centipedes are first scalded to death with boiling water, then the tails are cut off and the feces and urine are squeezed out. Then, a thin bamboo piece with the same length and width as the centipede is sharpened at both ends, one end is inserted under the centipede's jaw, and the other end is inserted into the tail. The centipede is straightened by the elastic force of the bamboo piece and placed in the sun to dry. If it is rainy, it can be dried with charcoal fire. After drying, take out the bamboo piece (do not break the head and tail, which will affect the quality), and place the centipedes of similar length with their heads facing one side, and clamp them horizontally at the dorsal and ventral parts with a thin bamboo piece about 1 cm wide, tie them into rows, 50 per row, and seal them in wooden boxes for storage.

Quality requirements: The finished centipede should be dry and flat, with a reddish-brown head, a black-green, shiny back, and two protruding ridges. The abdomen is brown and shrunken. The feet are yellow or reddish-brown and bent backwards. The last segment is like a thorn, with cracks or hollows in the cross section. It has a slightly fishy smell with a pungent odor, a spicy and slightly salty taste, a complete head and tail, no breakage, no insect bites, and no mildew.

Centipedes are divided into four grades: special grade, each one is more than 16.5cm long; first grade, each one is more than 13cm long; second grade, each one is more than 10cm long; third grade, each one is more than 6.6cm long.

On the one hand, its own characteristics are used to defend against natural enemies.

Because it protects yourself

It stinks, there's nothing we can do about it

2. There are centipede-like insects in my house. They have stripes and smell bad. What kind of insects are they? How can I get rid of them?

This is a kind of purple-brown centipede with a segmented shell on its body. We call it "straw sandal board". It will not harm people or animals. Just sprinkle some "666" powder or a little dichlorvos in those dark places.

Stink bugs, it is said that if they are disturbed by people, they will fart and the gas is very poisonous and may damage the eyes.

3. There is a kind of insect that looks like a centipede, but when you step on it to death, its body emits a very smelly odor. What kind of insect is it and how can you prevent it?

Sulfur and lime can prevent it, but killing it is easy.

Millipedes are insects similar to centipedes. They are non-toxic, but their body fluids have a foul odor after death. They are herbivorous insects.

Haha, spray dichlorvos on the corners

4. Why does the centipede still have a bad smell after being burned by fire?

Although the centipede was burned by fire, it is also a cellular animal with flesh and skin. It will produce a burnt smell. After a chemical reaction with fire, its corpse will also produce a burnt smell and the smell of burning flesh. This is normal.

5. Find the chemical substance that makes centipedes smell bad

Ammonia, phosphine, hydrogen sulfide gas
