Summer and autumn are the seasons of frequent activity of many insects, and there are many kinds of poisonous insects, such as mosquitoes and ticks. If you suddenly feel a pain and itch on your neck, what do ordinary people do?
Most people subconsciously slap it, and then it's a wipe, is it not easy to kill a bug? But there is one kind of bug, if you shoot it like this, it is likely to cause serious consequences, this kind of bug is cryptopterynhopper.
Once a man abroad accidentally crushed the cryptoptera that fell on the skin with his index finger, causing the index finger and skin burns and stinging, and the information about cryptopteryx toxins on the Internet was demonized, and with many terrible pictures of skin ulceration, it exaggerated its toxicity.
The man, fearing that cryptopteryx toxin would lead to his own death, chopped off his finger in fear and panic, but fortunately the broken finger was eventually picked up by the doctor. What exactly is that cryptoptera insect, and is it really so toxic?
Cryptoptera is actually a general term for a class of beetles, belonging to the insect class Coleoptera under the organism, scientists have found nearly 37,000 species of cryptoptera, cryptoptera body is narrow and long, body length of about 0.4 cm to 3 cm.
As the name suggests, cryptoptera is actually winged, but often hidden, the largest can grow to about 4 cm, delay success is called farmers, scientists with the help of high-speed cameras that can take more than 400 photos per second, only to see how cryptoptera spread its wings to take off, land, and finally fold its wings.
There are many members of the cryptoptera family, but there are only more than 200 kinds of poisonous cryptoptera, and there are mainly three kinds of poisonous cryptoptera in the mainland, namely yellow-footed, black-footed and strange poisonous cryptoptera.
The body color of the poisonous cryptopteryx is bright, black and yellow, appears in the humid water source in autumn, itself has a phototropic and high,Iterant,It is diurnal and nocturnal, often active on crops and weeds, feeding on a variety of small insects and rotting organic matter.
People's fear of cryptoptera mainly comes from some pictures and articles on the Internet, and these pictures and articles almost exaggerate the toxicity of cryptoptera in order to win eyeballs, making people feel afraid after watching. In fact, more than 90% of Cryptoptera are not toxic, and the toxicity of cryptoptera is not enough to be fatal.
So where did the scary images of Cryptoptera come from? In fact, in most cases, cryptopters have become back pot men, although a large amount of exposure to cryptoptera toxins can also cause herpes and erythema, but it is by no means as scary as in the online pictures. The creator of the online picture actually originated from a plant: poisonous kudzu.
Kudzu is a climbable plant, mainly distributed in the Americas, the leaves grow similar to the carob leaves, although it does not look dangerous, but the poisonous kudzu contains a large number of substances that can make people allergic to urushiol.
Urushiol is an oily organic substance, if the skin accidentally comes into contact with urushiol will cause allergic dermatitis, the skin will appear herpes and erythema, there is a burning and swelling pain, for those with obvious allergy manifestations, a large amount of urushiol can even cause death.
The "pot man" cryptoptera can also cause herpes and dermatitis, but the symptoms are mild. This series of symptoms is not caused by the bite of cryptoptera, which can lead to a series of symptoms after the outflow of viscous fluids and contact with human skin. Their venom is just a weapon to protect themselves, and if humans don't hurt them, they won't have an allergic reaction.
There are three ways in which cryptoptera toxins erode human skin:
The first is direct infection, which artificially shoots the poisonous cryptoptera on the skin to cause allergies; indirect infection, the fingers are contaminated with cryptoptera toxins, and then use the fingers to touch other parts of the body to cause infection; the poisonous cryptoptera sometimes hides in towels or clothing, and people crush them without knowing it to cause infection.
The degree of cryptoptera poisoning is actually related to the amount of venom contact, cryptoptera toxin will not cause life-threatening, a small amount of contact, the skin will only appear flaky erythema and itchy feeling, and when the amount of toxin is large, it may cause nausea, vomiting and other symptoms, after medical treatment, seven or eight days can restore health.
Cryptoptera toxins can sometimes cause herpes, you can gently squeeze the blisters with a cotton swab, rinse with iodine or saline, the toxin may also lead to necrosis of the skin tissue in contact, forming a scar that will slowly heal over time.
Therefore, when the cryptopters are found to be on the body, before being unsure whether they are poisonous cryptoptera, do not blindly flap, you can gently blow away, or use a pen, a book and other tools to pull it away, to avoid direct contact between the skin and the venom of cryptoptera.
Although some cryptoptera are indeed poisonous, this small insect is broadly beneficial to humans, and cryptoptera is a veritable beneficial insect.
In the control of agricultural pests, cryptoptera has also made its own contribution, it is the natural enemy of many pests, can catch pests that harm maize and rice and other crops, including aphids, blind bugs, cotton red spiders and other pests are cryptoptera food.
