The oldest and strongest human emotion is fear, and the oldest and strongest fear is the fear of the unknown.

It's the same with wild animals!

In many cases, people's fear and even hatred of animals comes from the unknown, and as we learn more about them, unnecessary fear will gradually disappear.

For example, the two climbing halls of the zoo, many people were very afraid of snakes at first, but through the science exhibition boards and the explanation and publicity of the keepers, people understand that they do not provoke snakes, and they will not take the initiative to attack people, and even snakes will make friends and value family affection.

There are project animals such as hognose snakes, which can be petted by yourself.

In the process, I gradually became less scared and understood that snakes are important members of the ecosystem and cannot harm them at will.

Fang Ye said with a smile: "So, although bats are ugly, don't dislike them or even hurt them because of this." ”

Wang Yan said: "Director Fang Yuan spoke very well. Many people may have this thought, since the source of the new crown may be bats, why not eliminate them, that will solve the problem?

In fact, bats are also very important cornerstone species, although they usually appear at night and are very inconspicuous, but they play a huge role in the ecosystem. ”

The host leaned forward and looked like he was listening: "Oh? ”

Wang Yan said: "Take mosquitoes as an example, everyone hates mosquitoes, right?" ”

Fang Ye echoed: "I'm afraid of mosquito bites!" When a mosquito bites, I will be swollen with a big bag, and it belongs to the kind of mosquito physique, living in a bedroom with people, and mosquitoes will bite me if they don't bite others. ”

The environment in the zoo is good, and of course there is no chance of being bitten by mosquitoes.

Fortunately, there is a systematic lottery, and some small props such as incense to repel mosquitoes have been drawn, which are more effective than mosquito nets, and mosquitoes will not fly in if the windows are open in the house, so that he can sleep peacefully.

"Many bats feed on insects, which are very important insect controllers, including mosquitoes, flies, moths, and many agricultural pests, and studies have shown that a bat can eat one-third of its own weight in insects every night," Wang said.

What is the concept, a 20-gram bat can prey on about 200-1000 small insects in one night, and a bat can eat 15-20 mosquito-sized insects in a minute.

In a community, conservatively speaking, there are more than ten or twenty bats, and they can eat tens of thousands of insects in one night. This is only what they eat on the surface, not including the offspring of these insects.

The reproduction speed of these small insects is very fast, mosquitoes can lay two or three hundred eggs at a time after sucking blood, and it only takes ten days and half a month from the eggs to hatch into adults.

If bats are not present, the insects can only be controlled with pesticides or other means. ”

The host was genuinely surprised: "Is it so powerful?" ”

At this time, the popularity of the show is getting higher and higher!

Many viewers are sending messages to friends or calling family members to come over and watch TV together.

Tang Xiaoxin was doing her homework, and she was also called to allow her to watch TV together.

Originally, I wanted to laugh when I heard Fang Ye say it, because she also had a physique that was particularly mosquito-friendly.

Seeing what Wang Yan said, his eyes widened: "One bat can kill thousands of mosquitoes in one night!" ”

Tang's mother was thoughtful at this time: "When I was a child, there were a lot of bats in front of my house, and I really didn't have much mosquito bites. ”

Tang Xiaoxin wailed: "Why don't we have bats here!" It would be nice if there were more bats, and I would never be afraid of mosquitoes when I sleep at night! ”

Dad Tang groaned: "Bats are indeed rare now!" If it weren't for this outbreak, I wouldn't have known there were bats in the community. ”

Tang Xiaoxin, who had participated in farming activities and learned about the impact of chemical fertilizers and pesticides on the rice ecosystem, had a guess in her heart: "It is probably the cause of pesticides!" Frogs and dragonflies are also hard to see now. When the insecticide kills the bugs, it poisons the bats. ”

sighed regretfully: "What a pity! ”

Wang Yan said: "If there were no bats, these mosquitoes and flies would be rampant, and our risk of infectious diseases would increase tenfold or dozens of times.

There is also their control of agricultural pests, according to statistics, a group of 150 large brown bats in the Midwest of the United States can eat 15 bugs and 60w leaf beetles every year, and if each female leaf beetle lays 110 eggs, they can prevent the birth of 33 million leaf beetle larvae and save a large number of pumpkins, cucumbers and other crops. ”

Fang Ye said: "We have a lot of traditional culture about bats in China, such as the word 'Fu' posted on the New Year, which is generally painted with bats, right, as well as various utensils and bat decorations on buildings.

Not only because of the homonym of the 'bat' and good fortune, but also because they really bring good luck, the chance of being bitten by mosquitoes in places with bats will be reduced, and the yield of crops will also increase.

Let's think about it, if all kinds of bad things happen where the bats are, will the ancients use it to make auspicious ornaments? Maybe the bat will be renamed Bat Evil and Bat Ugly. ”

"Wow!"

The audience in front of the TV exclaimed.

If some of the fears have just been dispelled, the attitude towards bats is now much different.

Before, I insisted on driving away the bats, and even killed the bats, and I faintly felt remorse!

This is a blessing that drives away the blessing!

"Yes, bats have always been a symbol of good luck, and we have lived with bats for so many years, and nothing has happened."

"It's a pot for those who eat game, not a pot for bats! Do not harm bats. ”

"When I was a child, there were bats that flew to my house to rest, and I borrowed them for one night and flew away."

"It's not bats that let the virus spread, it's the harm we do to wildlife."

"In addition to eating insects, bats are also prey on other carnivores, such as monkeys, raccoons, birds of prey, and snakes, among which birds and snakes are the main predators and are an indispensable part of the food web.

Bats are also important pollinators, with some feeding on nectar and pollen.

Over the course of their long evolution, there have been many plants whose flowers have been highly specialized and even bloomed specifically at night to attract bats to pollinate, such as gourd trees and cacti!

Flowers that rely on bat pollination vary in size, some of which are large and have wide stamens; Others may have petals that stick outward, as if providing a platform for bats to fall pollen on the stamens as they approach them.

There are also some fruit-eating bats, which are numerous and fly far, and the seeds in the fruit cannot be digested, and are spread in the process of the bat's flight.

For cave-dwelling bats, their droppings accumulate at the bottom of the cave, providing food for the insects and fungi that live in the cave.

So, if you were to slaughter bats on a large scale, the ecosystem would be hit hard. ”
