You are fighting in the heat and heat, and the spider is not idle, and it has entered the peak of breeding. As a special self-feeding class, spiders are more likely to attack other species when their counterparts cannot satisfy their appetite, and the most poisonous black widow also begins to hurt people. Talk to Healthy Everyday to learn the essentials of preparedness.
How poisonous is Black Widow? Let's look at an example: There are reports recently that a farmer in Hunan Province was accidentally bitten by a black widow spider while mowing grass, and he didn't pay much attention at first, insisted on working for a while, and then rode home on a tricycle. But before he got home, he fainted on the handlebar of the tricycle, his lips were dark, his breathing was weak, and he twitched from time to time. The violent convulsions caused the 57-year-old injured man to bite off four of his front teeth and kick the bed stalls. His family took him to the hospital, where he was rescued and woke up after 17 days in a coma.
Black widows belong to the bulbous arachnid family in animal taxonomy, appearing fatter than the average spider, resembling a small black bulb, which is widely distributed and is more common in warm environments. The black widow has a shiny appearance, and the female black widow will be 2 to 3 cm long, with a red hourglass-shaped pattern on the face, sometimes with two small erythemas. Males are smaller in stature and are rarely seen because they are eaten by females after breeding. Spider fertility is very strong, after the female spider breeding, in good conditions every 25-30 births once an egg, a lifetime can lay 5000 eggs. Each nest of baby spiders takes about 12-14 days to hatch and live together for about 14 days, then pull the roots from the belly and float downwind to start a new life. Black Widow likes to tie the net under the edge of the house or in the gutter, where there is sunlight on one side and shade on the other. Black Widow's venom is 15 times more powerful than that of the rattlesnake, but it does not secrete as much, and generally only poses a danger to young or infirm people. Spiders will first use webs to trap animals with poisonous juice, then break down their flesh into liquids and suck their flesh.
After a person is bitten by the black widow spider, it is difficult to detect at first, but the role of neurotoxins soon appears, and the wound will appear after a few minutes, fever and pain, and after a few small starts a large attack, a lot of sweating, muscle weakness, nausea, vomiting, tinnitus, rapid heartbeat or irregular beating, fever, convulsions and other symptoms, if not treated in time can lead to death. June to August is the peak of spider breeding, spiders are more active and more likely to attack people. In the summer, it is hot, take the children out for a walk in the evening, because the light is not good, be especially careful. When working in the wilderness, it is advisable to wear long pants and tie the cuffs of the pants tightly. Feel that there are bugs crawling into underwear, do not pounce, you should take off your clothes and carefully check, and find that there are spiders and then exorcise. If you are unfortunate enough to be bitten, do not exercise strenuously and should be sent to the hospital in time. If a limb bite occurs in the wild, the proximal end of the wound can be pressed or ligated on the way to the hospital, such as ligation with a rope strap, every 10 minutes to relax for two or three minutes and then ligation, and the summary tying time should not exceed two hours.
Spiders can hurt people, but they are not useless. Spider silk is stronger than steel wire, and researchers at the University of California announced that they have identified two key genes of spider silk protein, and may be able to imitate spider silk in the future. Hmmm, did you think of Wei Xiaobao's amulet armor? Or imagine building a fleet of thin and light body armor?
Black Widow also has interesting places. Canadian researchers have found that male spiders, in order to escape the sad fate of being eaten by female spiders after breeding, have evolved a strategy of choosing immature females to breed, because immature females can store bodily fluids until they reach maturity, so that males can continue their genes without risking their lives. This belongs to the rhythm of becoming a sperm.
