Chapter 714 (1/2)

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!”
