The little gray beetle will spew a very smelly gas

It's called a bug.

Known as the "stinky big sister", its scientific name is "Tsubaki elephant, also called "bug". There is a stinky gland opening behind the stinky big sister's body, and when it encounters an enemy, it emits a stinky gas, which is also called a "fart bug."

Stinky Girl", etc., resembling a cantharid.

When attacked, the fart bug can release a large amount of poisonous mist from the tip of its abdomen to spray at the attacker. To produce these pulse bombs, fart bugs have a gland inside their body that is specialized in storing different chemicals. When attacked, they mix these different chemicals in a pair of combustion chambers.

The toxic mist produced in the combustion chamber passes through the exoskeleton.

The exhaust hole is released, and the toxic mist is even accompanied by a sound. Some fart bugs in Africa also have a pivot nozzle that releases poison fog bombs that are more targeted and aggressive.

Many species are able to spray "ink", foul-smelling chemicals, or feces in their bodies. At these times, the most is to stain your clothes, and other than that, you don't have to worry about how serious the damage will be. But fart bugs take internal ejection to a whole new level:

It makes use of chemical reactions.

The force generated, which sprays out a boiling ** liquid, which can be discharged up to 70 times at a time, is simply a "napalm". When a bug is frightened, it mistakes it for an attack, and the stink gland will shoot venom at the human eye, so that the enemy cannot see it for a while, so that it can escape. When the venom is sprayed into the eyes, there will be tears on the spot, the eyes cannot be opened, severe pain, red and swollen eyes, and in severe cases, corneal burning defects and inflammation will occur.

You're not talking about a shield beetle, that's a way of self-defense.

Judging from your **, this is a greedy beetle, a beneficial insect, and harmless to people.

Chinese Insects, Insecta, Coleoptera, Insects of the family Carapace. body black, shiny; palate, periphery of upper lip, whiskers, antennae, lateral margin of dorsal plate and posterior part of thorax brownish-red; The ventral surface of the body is black-brown. The head is smooth and free of notches.

Adults appear from June to September and are a common species in agricultural areas. It feeds on insects such as spider mites and aphids, but can also feed on the seeds of wheat, barley, oats and millet crops. It is distributed in North Korea, Japan, Russia, and China.

This little bug is a small beetle. Looks a bit like a close relative of a morning glory. It's just that the tentacles are much shorter than those of petunias.

There are a lot of these beetles in the countryside. There is a bug bug like this, the little beetle. Grab it and it will spew stinky gas from the tail.

It's its defense system. Also, don't get bitten by its jaw. Although it is a little toxin, it does not pose a threat to adults, but the ** of young children is too tender and will still be bitten.

Don't be too afraid that this bug is harmless, we often catch such beetles when we were children.

I do not know. It could be a monster, but I don't have it at home.

When I was in my dormitory, I was always bitten by bugs. I didn't see what the insects looked like, and finally found that the mattress on the top bunk was a straw mat, (when he moved in, there were two mattresses, one grass and one brown silk) I heard that the grass mat loves to give birth to insects, and it will be fine if the straw mat is skimmed. The best treatment for bed bugs is to spray blue whiss, you can use insecticides do not use physical methods, one is not good, the other is that the eggs are not dead if they are easy to breed again, the small bag of biting is not big, but it is very itchy, garlic toothpaste is not good to use, and the last cool oil bought to stop itching.

For insects, you can buy insecticides, spray the house, and then close the doors and windows, and people should not stay indoors for 2-3 hours to ventilate, it should not be a big problem.

It is the largest group of species in the Hemiptera, with about 5,000 species in the world.

The last segment of the antennae ends 2 and 3 parts are orange-yellow or orange-brown, partly, individuals are partly in the first.

There is still a section of orange-yellow or orange-brown spots in the second and third segments. There is the outer edge of the dorsal plate of the prothorax plate.

Tsubaki elephant (3 photos).

A sharp spike with a transverse arc of orange-yellow or orange-brown spots.

The membranous part of the upper wing is dark brown. The abdomen is partially exposed on the outside of the upper wing, and each segment has small orange spots. The hind feet are particularly well developed, especially the basal half of the tibial joint, which is flattened in the leaf-like shape, which is the main distinguishing feature of this species.

There are many yellow spots on the ventral surface of the body; The most distinctive feature is the leaf-like appearance of the tibial joints of the hind feet.

The anterior half of the upper wing is leathery, and the membranous part is triple conical in the ventral dorsal. It has a well-developed stabbing mouthparts. The eggs are cylindrical in shape with a lid on top, and are often laid neatly on the leaves.

terrestrial Tsubaki elephants developed short whip-like antennae; Most of the aquatic elephants have sickle-like front feet; The middle and hind legs of the amphibian elephant are particularly slender, and at first glance they resemble spiders.

The common ones are insects that prey on small insects and are beneficial to agriculture, nine spice insects for traditional Chinese medicine, osmanthus cicadas for food, and military matching insects that harm agriculture, and soft-shelled turtles and pine algae that specialize in preying on juvenile fish for the breeding industry, etc., and the Tsubaki family belongs to the order Hemiptera.

Tsubaki elephant, also called bug elephant, Tsubaki insect, common name fart insect, stinky sister. There are more than 30,000 species of Tsubaki elephants, with flat bodies and tiny to large ones. The mouthparts are long and beak-shaped, suitable for stabbing and suctioning.

forewing basal half leathery, terminal half membranous; The hindwings are all membranous or vestigial. There is an opening of volatile odor glands next to the basal ganglion of the hind foot, which releases odor when encountering the enemy, so it has the name of "fart bug". It doesn't bite, but it stinks.

Control method: It can be sprayed with 1000 times dilution of 80% trichlorfon [span] emulsion or 800 1000 times dilution of 90% trichlorfon crystals. If some pine alkali mixture is added to the trichlorfon [span] solution, the control effect can be improved, and it can be mastered.

The control effect of the first and second instar nymph stage is better.

You can't tell you clearly, smelly beetles are more common, and the famous ones are Tsubaki elephants, which generally don't bite.

How to prevent this kind of worm, there are many in rural areas.

Something in the house that attracts this kind of bug.

Isn't there a lot of greenery outside your house?

There are still some tall trees.

Bed worms like to bite the most place is the neck, limbs and other places, people wear little sleep in summer, they generally only bite the exposed outside of the place, other posts on the Internet say that the whole body should be wrapped in clothes or plastic wrap to sleep, not joking, I thought about it, but in the summer of Shenzhen, there is no air conditioning, I think this method is particularly unreliable. So at that time, I was almost having a nervous breakdown, and it was also a variety of distress posts, and I summed up a lot of other people's experiences to make my family now bed worms extinct. Spray the guard, don't ask me why, the corpses of bed worms fell on the ground three minutes after this medicine was administered, it is very powerful, and now I have been in the dormitory for a year, and there are no bed worms.

In fact, bed worms are not terrible, but people have almost failed many times and given up, and if you persist, you will find that success is not far away. There are also some people who don't react at all after being bitten, because in fact, redness, swelling and itching are common allergic reactions, which are related to the difference in human physique.

It's a bed bug, this thing has a very strong vitality, it can't be starved to death for several months, the temperature is between 16 degrees and 50 degrees, it's very lively, afraid of Quanguang, it's best to encounter this kind of insect It's best to carefully disinfect the whole house at high temperature, and wait for a week to repeat, because the peak breeding period is seven to fifteen days is a generation, and if you want to cut grass and eradicate roots, you have to disinfect it two or three times. After the bed bug bites, there is a red bump and itching. Therefore, the grass must be cut to the roots.

Don't ask my brother how do you know, my brother used to be a victim, and he sprayed Blue Whiss directly, and dropped insects all over the place, and he didn't ** for half a year.

This kind of insect should not be underestimated, it is very good at biting, and the effective way to repel the enemy is to kill the insect repellent spray.

Introduction to insectsdarkling beetle

It is found on all continents, but is more common in warm, dry regions. Eat more dry and rotten plant or animal tissues, some burrow wood, some eat the larvae of other animals or live in ant nests. Body length 2, 35 mm(1 12 inches), flat to cylindrical.

The larvae are about 25 mm long and cylindrical. Mealworm larvae are used as food for birds and fish, but mealworms and tribolium confusum are warehouse pests. The remains of miscellaneous grain thieves were found in a grain jar from an Egyptian tomb around 2500 B.C.

Heterogeneous pirates can be fed in large quantities under various experimental conditions, so they are also used as experimental materials for population ecology, genetics and behavioral studies. The head of the bolitotherus cornutus has a pair of blunt horn-like processes, and the adult body is 10 12 mm long, black, and the elytra resemble a piece of bark. Eleodes is large, smooth, and has no hind wings; In dry areas, the two elytra heal to reduce the evaporation of water from the body.

When frightened, the back of the body secretes an unpleasant oily liquid as a defense. Resembles insect eggs.

I want to ask what kind of insect this is, and then how do you prevent insects in the end, can you please reply, tell me, thank you.

My house also has such bugs at night, and I want to know what to do.

Gnats, also called copy

Moths, moth flies, butterfly flies, gutter flies, etc. Common ones include the white-spotted moth midge and the star-spotted midge.

When the adult of the moth midge is at rest, the wings are mostly ridge-like oblique on the body or obliquely upward, and there are different colored hairs on the wings to form markings, and the wings are hairy or scaly and resemble small moths, so there are names such as moth gnats, moths, and sandflies. The radial veins of the wing veins are divided into 4 veins, and the terminal segment of the cubital vein Cu1 is long and extends parallel to the midrib M4. Mouthparts are short and do not suck blood.

There are many species of this subfamily, and the adults are often found in dwellings, and the larvae mostly breed in sewers. It breeds mainly in shallow waters containing spoilage organic matter, septic tanks, cesspools, toilets, bathroom washbasins, stagnant water on the floor, kitchen sinks, damp rags, etcand so on, and a large number of gnats can be cultivated. Outdoor gnats larvae can also be found in silt gutters, septic tanks, and some containers of stagnant water with high organic matter.

Most of the adult gnats that emerge are parked on the nearby walls.

Control method: Kill adult insects. Adults fly slowly, and can be eliminated with fly swatters, electric mosquito swatters, etc., or they can be sprayed with insecticides and then close the bathroom door tightly for half an hour.

Try to keep the bathroom and kitchen dry.

There should be no stagnant water in the bathroom, the soap box should be hung as much as possible, and the mop and rag should be dried to prevent it from being in a damp state for a long time.

The use of deodorant floor drains can effectively prevent the fledging adults from flying out.

Scald floor drains and sewers with solid pipe unclogging agent or boiling water once a week.
