The strong smell of blood tempts it,
Hunting and sucking blood is its fatal contract,
The instinctive light mouthpiece reveals a long lip and tongue,
The compound eyes were covered with blood and flashed a seductive light,
Let all prey "be willing to fall",
In this way, they are absolutely noble and elegant
Drop a passionate kiss on your prey...
Who are they?
They're arrogant blood-sucking insects.
Even if you don't want to, there's nothing you can do!
Ran Goose,
The saddest thing is not that you've been sucked in blood.
The saddest thing is that it "kissed" you,
You don't know who it is yet?!
In this way, I suffered a loss in vain
Now xiaobian heroically dedicates himself to tell you about the blood-sucking diary of blood-sucking insects.
"Doesn't it suck my blood when I know it?"
"Of course not--(̄Д ̄)--,you know it,
At least when it's sucked in blood and cursed in circles,
Say its name. ”
Q1. What are blood-sucking insects?
Blood-sucking insects refer to insects with blood-sucking ability in the insect order (soul interpretation), which are mainly divided into 4 orders: hemiptera, lice, fleas, and diptera.
Q2. The dangers of blood-sucking insects?
Blood-sucking insects live by sucking the blood of people or animals. They suck blood, cause mechanical damage, spread diseases, and cause varying degrees of physical and psychological harm to everyone.
。。。
Look, in order to fight with blood-sucking insects,
A lot of people have lost their minds,
Some feudal superstitious practices were used...
It is said that vampires are afraid of the cross!
In order to save everyone's sanity,
Adopt a more scientific method of deworming,
Xiaobian is going to enlarge the move:
Who, I call you, do you dare to say yes!
Who are you calling it?
Hemiptera of blood-sucking insects
bedbug
Bed bugs are insects of the hemiptera bed bug family and are a worldwide distribution of sanitary pests. These insects are extremely annoying, not only because they have a pair of odor glands that can secrete an unusually foul-smelling liquid to defend against predators and promote mating, but also leave a bad odor everywhere they go, but they are more than 90 kinds of people, both "men and women", young and old (nymphs and adults, both male and female suck blood) all suck blood.
In addition, the "bugs" of bed bugs are also extremely bad: the attitude towards their "blood donors" is just bad, and the treatment of their beloved sisters is also very rogue. The male bed bug is an out-and-out sex ghost, and the temperament is impatient, seeing the female will pounce on it, whether people like it or not, where the genitals are, they will use their spiked genitals to poke randomly, poke into it directly and forcibly infuse sperm.
Bed bugs hide between crevices during the day, are nocturnal, and when it comes to blood sucking, they are not strictly selective to the host, and the younger the nymph, the stronger the blood-sucking ability. Fortunately, most of the bed bugs suck the blood of bats and birds, and the only two species of stinging sucking human blood are temperate bed bug cimex lectularius and tropical bed bug cimex hemipterus.
Cone bugs
The cone bug is a common name for insects in the subfamily Cone bug family Hemiptera, named after its narrow cone-like head. Most of the cone bugs survive in the wild, and a small number have adapted to human life. They are nymphs and adults, both male and female, suck blood and body fluids from their mouths, and will suck the blood and body fluids of mammals, birds, reptiles, bed bugs, and even the same kind.
Also known as the "kissing bug", the cone bug sounds quite romantic at first glance, but in fact its blood-sucking method is quite evil. Cone bugs specialize in biting people's faces and like to look for areas with thinner skin, such as the lips, eyelids, etc. They are large in size and suck a lot of blood at once.
Not only that, but trypanosomiasis is the main vector for the transmission of trypanosomiasis in the Americas. After a trypano bug bites a victim, a parasite called Trypanosoma cruzi enters the human bloodstream and eventually enters the heart and survives and multiplies in the heart. Infected people develop symptoms similar to AIDS in the early stages of the disease, are easily transmitted by blood, and may be transmitted from mother to child during pregnancy and childbirth.
Patients with latent trypanosomiasis have no symptoms in the body, and once the disease occurs, it may lead to heart failure or other fatal diseases, so it is also called "new AIDS".
Scared, I carried the dried fish around 360 times
It is said that the great biologist Darwin suffered from three different diseases in his later years, one of which was American trypanosomiasis, which is also likely the cause of his death. He wrote in the Voyages of the Beagle, "At night I was bitten by a large black worm in the Pembas steppe of Argentina. A wingless insect crawls on top of you and you will always feel very uncomfortable. The insect is about 1 inch (about 2.5 cm) long. ”
Well, as a well-known biologist, Darwin didn't know that it was the cone bug that bit him!
Lice of blood-sucking insects
louse
Insects of the order Lice are commonly known as lice, referred to as lice, and sucking louse in English. These include the traditional lice anoplura and the hair-eating order mallophaga. There are more than 5,000 known species in the world, and more than 1,000 species are known in China.
The lice are small and wingless, but have stubby climbing feet and strong claws that bend inward, clamping with the protruding pincers at the tip of the tibia to grip the hairs, making it difficult to break free as long as it is caught. They are nymphs and adults, both male and female, and live a lifelong obligate parasitism outside birds or mammals, with a host specificity.
Although lice have host specificity, but can not stand it variety, large number, fast reproduction, strong blood sucking, many birds and animals are infected by a variety of lice, most birds have 4 to 5 species, but also parasitic in different parts (lice, here I express deep admiration, this social division of labor is really good).
There are also many kinds of lice that can parasitize the human body, including: pubic lice, head lice, and body lice. When I was a child, I was also deeply affected by lice: when I was in elementary school, there was a small tablemate, and I found that he was covered with lice and white lice (lice eggs), and I went, densely packed tops and pants, I can't count how many, and I was disgusted to think about. At that time, he also said to me very enthusiastically, "I'll do you magic and tricks", and then scratched his body, felt out a lice and put it on the desk, and rushed to play. Well, he's a great magician, gorgeously turning lice into me.
At first, I still remembered him, but then I let go. Because this matter has been around for a long time, in ancient times, there were many soldiers in Wei and Jin, and there were many lice on the bodies of famous people. "Talking about lice" and "talking about lice" seemed inconceivable today, but at that time it was the most fashionable and common thing, and it became a beautiful talk (forehead, far away).
Flea of blood-sucking insects
flea
Fleas are commonly known as fleas [zǎo], abbreviated as fleas; English is fea. At present, about 2500 species of fleas have been recorded in the world, and more than 700 species have been recorded in China.
Fleas are completely metamorphic insects, and they are very small, only a few millimeters in size. Although they have no wings, they are very good at jumping because of their rounded breasts and a pair of muscular hind feet. The study found that fleas can jump 30 cm high, which is equivalent to a 1.2 m child jumping over a distance of 4 football fields. It is also thanks to the extraordinary jumping ability that fleas can easily jump on when the host animal passes by.
Blood sucking is the only way fleas can get nutrients: some species are free to move outside the host body, and only when sucking blood, the mouthparts pierce the skin of the host for a short time but frequently; others permanently burrow the entire body under the skin of the host, leaving a hole in the skin to breathe, feces and lay eggs.
Everyone hates fleas, but one person loves it so much that he runs a flea circus that tailors a circus program for pet fleas, and if they are hungry and have no strength, they put them on their bodies and suck their own blood.
Diptera of blood-sucking insects
mosquito
Diptera insects are blood-sucking households, although not all insects of the order suck blood, but most insects, including: mosquitoes, midges, flies, flies and other 3 suborders and 9 families are blood-sucking for a living. There are 150,000 known species of dipteran insects in the world, and more than 16,000 species have been recorded in China.
Among so many dipteroded insects, the most annoying of them is the mosquito. In order to suck blood, they also spent a lot of effort to enhance their weapons and equipment, the mouthpiece. Although the mouthparts of mosquitoes and other blood-sucking insects (bed bugs, cone bugs, lice, lice, fleas) are all sucking mouthparts, they are very different. The mouthparts of mosquitoes have 6 needles, and in addition to the two pairs of upper jaw and lower jaw needles, the upper lip and tongue have also become mouth needles.
The needle is not hard and unbendable, but can swim freely in the skin. When the upper and lower jaws of the mosquito freely bend between the skin and flesh, looking for suitable capillaries, the upper lip and tongue begin to work, the upper lip is responsible for sucking blood, and the tongue injects saliva into the body. As a result, mosquito-borne pathogens are also transmitted to the human body.
However, it is worth noting that mosquitoes only female adults suck blood, male mosquitoes are mainly nectar and plant juice, and female mosquitoes maintain normal survival by sucking nectar and plant sap, but only after sucking blood, their ovaries can develop. And not all insects called "mosquitoes" are blood-sucking, such as: large mosquitoes of the family Of Large Mosquitoes, dumb and long legs, commonly found at the water's edge and in the bushes, they never bite people, and they can be calm when they meet later.
Large mosquitoes
Also common among the blood-sucking insects of diptera are insects of the midge family, commonly known as the ink mosquito or small bite. Their feeding habits are divided into two categories: one is based on plant sap and nectar; the other is based on animal blood, and female midges suck blood, while male midges only suck plant juice for nutrition.
Diptera flies, because they suck blood on the bodies of cattle, horses, etc., have common names such as cattle flies and horse flies. The mouthparts of the bullfly are different from the sucking mouthparts of mosquitoes and are called the stinging mouthpieces.
Unlike the delicate operation of mosquitoes, the mouthparts of the cattle fly are like a series of sharp short knives, roughly poking at the skin of the host, and then licking the blood flowing out of the lower lip. Like mosquitoes and midges, cattle flies are only female adults who suck blood, and males suck only plant sap. Usually adult flies generally suck blood on animal bodies and do not suck human blood, with the exception of cantharids and cannabis flies.
In addition to the mosquito family, midge family, and flies, the blood-sucking insects of diptera also include: flies, whiteflies, tsetse flies, flies, lice flies, arachnids, and bat flies.
Ah, so many insects are sucking blood!
