Chapter 714

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

The same is true for wild animals!

Many times, people's fear and even hatred of animals actually come from the unknown. With the in-depth understanding of them, unnecessary fear will gradually disappear.

Like the two climbing halls in the zoo, many people were afraid of snakes at first. Through the explanation and publicity of popular science exhibition boards and breeders, people learned that it would not provoke snakes, it would not take the initiative to attack people, and even snakes would make friends and pay attention to family affection.

There are project animals such as pig nosed snakes. You can touch them yourself.

In this process, I gradually became less afraid and realized that snakes are an important member of the ecosystem and can't hurt 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, "Mr. Fang spoke very well.

In fact, bats are also very important cornerstone species. Although they usually appear at night, they play a huge role in the ecosystem. "

The host leaned forward, showing a look of serious listening: "Oh?"

Wang Yan said, "take mosquitoes for example. Mosquitoes are very annoying, aren't they?"

Fang Ye echoed: "I'm very afraid of mosquito bites! Once a mosquito bites, I will swell up a big bag, and it belongs to the kind of mosquito attraction constitution. If I live in a bedroom with people, mosquitoes will bite me if they don't bite others."

The environment in the zoo is good. Of course, there is no shortage of opportunities to be bitten by mosquitoes.

Fortunately, there is a systematic lottery. Some props such as mosquito repellent incense have been pulled out, which is more effective than mosquito nets. Mosquitoes will not fly in with the windows open in the house, so that he can have a safe sleep.

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

What's the concept? A 20 gram bat can prey on about 200-1000 small insects in a night. A bat can eat 15-20 mosquito sized insects in a minute.

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

These small insects multiply very fast. Mosquitoes can lay two or three hundred eggs at a time after sucking blood. It takes only ten days and a half months from egg hatching to adult.

If there are no bats, they can only be controlled by pesticides or other means. "

The host was genuinely surprised and said, "is it so powerful?"

At this time, the program is becoming more and more popular!

Many viewers are sending messages to friends or calling their families to watch TV.

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

Originally, Fang Ye wanted to laugh because she also had a special constitution to attract mosquitoes.

Seeing what Wang Yan said, he stared: "a bat can kill thousands of mosquitoes in a night!"

Tang Ma thought at this time: "when I was a child, there were many bats at my door. I really didn't get bitten by mosquitoes."

Tang Xiaoxin wailed: "why don't we have bats here! If only there were more bats, I wouldn't be afraid of mosquitoes at night!"

"Bats are really rare now. If it weren't for this epidemic, I didn't know there were bats in the community," said Tang dad

Tang Xiaoxin participated in farming activities and understood the impact of chemical fertilizers and pesticides on the paddy ecosystem. She guessed: "it's probably the cause of pesticides! Frogs and dragonflies are hard to see now. When pesticides kill insects, they poison bats."

Regretfully sighed: "what a pity!"

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

And their control of agricultural pests. According to statistics, a group of 150 big brown bats in the Midwest of the United States can eat 15W leaf cicadas, 19W gill golden turtles, 33W stink bugs and 60W leaf beetles every year. 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 pumpkin, cucumber and other crops. "

Fang ye said, "we have a lot of traditional culture about bats in China. For example, the word" Fu "pasted in the new year is usually painted with bats, right? There are also bat patterns on various utensils and buildings. In the past, gifts decorated with bats and deer were given to the elderly on their birthday. In addition, the elderly's birthday star is" Fu Lu Shou ".

Not only are bats homonymous with luck, they can really bring good luck. Where there are bats, the probability of getting sick from mosquito bites will be reduced, and the harvest of crops will also be improved.

Let's think about it. If the bat is located, all kinds of bad things will happen. Would the ancients use it as an auspicious decoration? Maybe the bat will be renamed batevil and batugly. "

"Wow!"

The audience in front of the TV exclaimed.

If we say that we have just dispelled some fears, our attitude towards bats has changed greatly.

Before, those who insisted on driving away the bats and even killed the bats had a vague feeling of regret!

This is driving away the blessing!

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

"When I was a child, bats flew home to rest. They stayed for one night and flew away."

Wang Yan continued: "in addition to eating insects, bats are also prey of other carnivores, such as monkeys, raccoons, raptors and snakes. Birds and snakes are the main predators and an indispensable part of the food web.

Bats are also important pollinators. Some bats feed on nectar and pollen.

In the long process of evolution, the flowers of many plants are highly specialized, and even bloom at night to attract bats to pollinate, such as gourd trees and cactus!

The flowers pollinated by bats vary in size, some of which are large and have broad stamens; others may have outward extending petals, as if providing a platform for bats. When bats approach the stamens, pollen falls on them.

There are also bats that eat fruit. They have a large number and fly far. The seeds in the fruit cannot be digested and are spread during the flight of bats.

For bats living in caves, their feces accumulate at the bottom of the cave, providing food for insects and fungi living in the cave.

So if we want to eliminate bats on a large scale, the ecosystem will be hit hard. "
