If mosquitoes disappear in this world, what impact will they have on humans? The result is not so simple
mosquitoes cause a large number of human infections and deaths every year, which brings a huge medical burden. Therefore, some researchers advocate the extinction of mosquitoes, but mosquitoes have their own role in ecology. It is not only difficult to eliminate mosquitoes, but also what kind of impact will it have.
Every morning, Murphy will open a locked door of the Walter Reed Army Research Institute in Maryland. There are many mosquitoes that carry malaria. She fed fish food to millions of larvae (mosquito larvae), and then asked them to bite unconscious mice in their abdomen. Need 24 mice every month. Murphy has been studying mosquitoes for 20 years, hoping to limit the speed at which mosquitoes can spread the virus, and even hope that mosquitoes can completely disappear from the world.
Many people have the same feeling. Every year, 247 million people are infected with malaria, causing nearly 1 million deaths. I really want them to disappear
What if there are no mosquitoes in the world?
Scientists tried to answer this question and studied some surprising answers to mosquito biology and ecology.
There are 3,500 species of mosquitoes known in the world, of which only a few will bite humans. They are found all over the world, in various habitats, and are important members of many ecosystems.
Murphy said that mosquitoes have lived on the earth for more than 100 million years and have evolved with many species. Eliminating mosquitoes will cause predators to lose their prey and plants to lose pollinators. A world without mosquitoes is more than imagination. At present, countries have invested in various ways to get rid of the most harmful mosquitoes in the world, which have the most pathogens.
Scientists understand that even without mosquitoes, other species will be replaced, and the ecology will function as usual, or even better.
Arctic pests
Eliminating mosquitoes may have the greatest ecological impact on the Arctic tundra. Many mosquitoes originate from this. After laying eggs, the insects will hatch after next year, and then it only takes three to four weeks to grow into adults. In cold Russia, the number of mosquitoes is also very high.
If the mosquitoes disappear, there is still no conclusion. Harrison, an entomologist at the North Carolina Department of Environment and Natural Resources, estimates that without mosquitoes, the number of migratory birds nesting in the tundra would be reduced by half.
Other researchers disagree with the wild zoologist Debbie of Alaska in the United States who said that when sampling the stomachs of birds, there were not a lot of mosquitoes in the polar circle, but more Eat bugs frequently. "Because humans are easy to notice mosquitoes. Let us overestimate the number of mosquitoes in the Arctic."
Every day, the mosquitoes in the reindeer group draw 300 ml of blood from each reindeer. It is believed that the reindeer choose the wind route to avoid mosquitoes. The direction of reindeer migration has slightly changed, which will have a major impact on the polar regions. Many reindeer trample on lichen, lick lichen, transport nutrients, become prey of wolves, and change the ecology. In this way, without mosquitoes, it does affect the Arctic, but what about the rest of the earth?
Mosquitoes used as food
Water entomologist Melitt of Michigan State University said that mosquitoes are easy to find and easy to catch. If there are no blemishes, hundreds of fish will have to change their eating habits in order to survive.
This sounds simple, but fish’s predatory habits are usually quite fixed. For example, big belly fish is good at eating mosquitoes hidden in rice fields and swimming pools. As the mosquitoes disappear, they may disappear, and they attack the entire food chain.
Many spiders, crickets, geckos and frogs have also lost important food sources.
If there are many food sources, most animals that feed on insects do notWill go hungry because the mosquitoes disappear, the evidence so far is not enough to prevent humans from killing mosquitoes.
serves you
If you lose mosquitoes, thousands of plants will also lose pollinators. Adult mosquitoes feed on nectar (only certain types of female mosquitoes get Only by sucking blood can we obtain the protein needed for laying eggs). However, McAllister said that for the crops that humans depend on, the pollination function of mosquitoes is not so important. "If the existence of mosquitoes is beneficial, humans have already discovered the way to use them, but we only hope that the mosquitoes are as far away as possible. ".
Every kind of creature has its necessary role in nature, and it is difficult to convince the public. And the reason why it is difficult to kill mosquitoes is not because humans do not want to kill mosquitoes, but because the ways to kill mosquitoes are limited.
Today, human beings continue to make tuna, corals and other useful species endangered, but they cannot threaten the survival of mosquitoes. American entomologist Coron said that mosquitoes do not play any important role in the environment. If mosquitoes die tomorrow, the ecological environment will continue to evolve, and other organisms will replace mosquitoes. Of course, it is not known whether it is good or bad. But the result is not that simple
Annoying mosquitoes, summer will come again soon! We use eighteen weapons to kill mosquitoes but you know what! ?
电 Mosquito-repellent lamp will always forget to unplug it, always plugged in for fear of fire, mosquito coils or insecticides contain a lot of chemical ingredients
