Every summer, mosquitoes have become the "enemy" of almost all land vertebrates, and when mosquitoes are mentioned, many people hate them to the bone, hoping that they will disappear from the earth immediately, but no matter how the earth's climate changes, the number of mosquitoes is increasing.
In July 2020, after the hurricane, many places in the United States caused a "mosquito plague", and many livestock were directly bitten alive, so the "human mosquito war" was about to erupt, and in 2021, the United States plans to release 1 billion genetically modified mosquitoes, in order to control the number of mosquitoes.
The most frightening part of mosquitoes is not their bites, but their spread of the virus, such as yellow fever, chikungunya, West Nile, dengue fever and Zika, where tens of thousands of people die each year.
Kissing insects that specialize in biting animals' lips
In addition to mosquitoes, there is another terrible flying insect in the world, statistics show that because of its existence, it causes nearly 10,000 deaths every year, this flying insect is named kissing insect, kissing insect, what a romantic and seductive name, it is easy to make people have beautiful fantasies.
So named because it sucks blood specifically on the lips of humans and other vertebrates, when humans and animals are asleep, the kissing insect will sneak to the lips, and when the kissing insect bites, it will also release a protein, causing an allergic reaction in sensitive and sensitized individuals.
The blood sucking is well sucked, and the kissing insect, after eating and drinking enough, also does a very shameless thing, excreting feces into the wound so that the animal can be infected with parasites, just by virtue of this, it is much more shameless than the mosquitoes that hate it to the bone, it is simply shameless to the extreme.
It should be known that the feces of the kissing insect contain a tiny parasite - Trypanosoma cruzi, which will multiply in the host heart as soon as the wound enters the bloodstream, and eventually cause the host to die of heart failure, which is called Chax disease.
So, being bitten by a kissing insect is called the dreaded "kiss of death" by scientists, because that kiss could make you fatal.
Adult kissing insects are about 14 mm long, the growth process to go through five completely different forms, just hatched when only 2 mm long, no wings, after five forms of growth, only to obtain two pairs of wings, grow into adults.
In the world, there are more than 130 species of kissing insects, mainly distributed in Latin America, and a few distributed in Asia, Africa and Australia, but China has not found them for the time being.
In order to facilitate the consumption of animal blood, kissing insects build their nests near animal shelters, living in underground burrows of rodents or armadillos, in the tree houses of bats, birds, sloths or possums, and 5% of kissing insects often live around human houses or human houses or in livestock shelters.
During the day, the kissing insect hides in the nest, and at night it appears to look for blood, and the smell, heat and carbon dioxide of the animal will attract a large number of kissing insects, in addition, the kissing insect is also easily attracted by light, often coming to the place where there is light.
In 1909, Chaks disease was first discovered by brazilian doctor Carlos Chagas, and in 1940, researchers in Texas in the United States conducted a study on humans and found that the main spreader of Chaaks disease was actually a kissing insect.
In real life, many people who get sick don't even know they have been infected with Chagas disease, because they don't have any symptoms in the early stages of infection, and when they have fever, fatigue, lymphadenopathy and "flu-like" symptoms, the condition is already very serious.
In addition, 30% of people with Chaaks disease develop heart and gastrointestinal complications, and patients rarely suspect that they have Chaaks disease.
summary
Although mosquitoes are hateful, but have been widely concerned by humans, so far, has mastered a variety of prevention and control knowledge, prevention and control is also very simple, and even bred genetically modified mosquitoes, so that the number of mosquitoes is getting smaller and smaller, and finally to extinction.
But the kissing insect, I believe many people do not know much about it, how to control, but also do not know anything, it has become another flying insect in the world that is enough to make people deadly.
