Hello everyone, I am a star brother said farmer, last October I went to my father-in-law's house to harvest rice, my father-in-law's family in the Anhui Mountains at an altitude of more than 500 meters, where the sky is high and cloudy, the rows of terraces are like a picture, because of the high altitude, the terrace area is small, the rice harvesting is still all artificial, to the place, the mountains are full of farmers harvesting rice, sickles, straw hats, artificial threshing machines can be seen everywhere, shallow ripples in the low-lying areas of the rice fields, I just want to go down to the field to cut rice, my father-in-law said, there are leeches in the water, that is, locusts, to wear rubber shoes, Applying wind oil or garlic juice to the cuffs can drive away leeches, but I don't think so.
Harvesting rice is more tiring than harvesting wheat, dry for about half an hour, I feel the pain and itching in the neck of the foot, open the pants to take a look, three or four leeches are greedily stinging on the skin to suck blood, locusts are as big as adult thumbs, black and yellow, I can't tear it off, my wife and brother said to shoot with the palm of my hand, or bake with a lighter, it will fall down, if it is drilled into the skin, it will breed life in the human body, until it is drunk dry blood, I am a little afraid after listening, is there such a mystery, leeches into the human body can really survive? Can it still reproduce? A bit sensational!
I remember when I was a child, Brother Xing was the most fond of playing in the river, fishing and catching shrimp, summer evening, with a body of dry heat, fluttering and jumping into the feeling of the river, still fresh in my memory, but into the small river, adults will say don't stand still, otherwise leeches will adsorb the body, if it enters the body through the mouth or nose, it will live in the human body, people do not die It does not come out, so at that time as long as you jump into the river, the legs and feet do not stop moving, did not think that they had learned to float, but occasionally after going ashore, there are still leeches adsorbed on the belly, The legs and stomach were brought out, and I was still a little scared.
First, can leeches survive when they enter the human body?
First of all, leeches are a kind of blood sucking insects, not parasites, leeches belong to cold-blooded links, it mainly lives in the ditches, paddy fields, and lakes in fresh water, especially rice fields, ponds are the most common, like to suck human and animal blood, it is actually omnivorous animals, plankton in the water, mollusks, algae are its food, which shows that its life is inseparable from the air, can not breathe without oxygen, which is also the reason why it sucks human blood, there will always be a section of exposed outside the body, as for the in vitro into the human body is simply impossible, There's never going to be a hole in someone who can't feel it, right? The only possibility of entering the human body is its eggs, which are brought in by drinking unclean water, but the development of eggs is inseparable from air, so leeches cannot survive.
Second, can leeches reproduce in the human body
Leeches are hermaphrodites, allogeneic mating, that is to say, leeches in its reproductive stage, can change gender, that is to say, during the breeding period it can be a father, can also be a mother, but breeding must be two heterosexual combinations, and because the breeding period still needs air to support it to survive, so in the body closed environment can not reproduce, those who say that entering the human body to swallow blood are deceptive ghost tricks, scare and frighten children, it is false at all.
In short, there are many leeches in the rural rivers, the water is bitten by it, vigorously slapped with the hand or burned with fire, it will be loose, pulling with the hand is not feasible, of course, it will not drill into the human body, at most it will fall down when it is full, in case you accidentally drink its eggs into the stomach, do not worry, there is no air, the eggs will only die, but it is necessary to prevent the parasites it may carry, which needs to be treated in the hospital.
