Survival Master of Wilderness Live

Chapter 231

Not long after, Chen Hu and Isabel walked out of the baobab tree hole, each holding a light tube device in their hands, but it was a portable spectrometer. They were too lazy to move any more, and they all lay down in the corner and fell asleep.

At this moment, the moon and silver stars are sparse, and the vast prairie is pitch black, but the moonlight illuminates the earth. As long as human eyes get used to this light, they can still see the surrounding environment clearly.

Chen Hu walked with Isabel on the grassland under the moonlight with the lamp device, and then asked:

"Isa little... Doctor, what animal are we going to study tonight?"

Hearing this, Isabel turned on the light tube in her hand, and a purple light appeared immediately.

"Many insects are nocturnal, and they have a strong phototaxis. The first topic tonight is to investigate the types of insects."

After finishing speaking, Isabel also asked Chen Hu to turn on the light tube, and then held it with her hand, waiting for the insects to fly over. During this process, Isabel did not forget to explain:

"Many insects respond differently to the intensity of light and the short wavelength of light. Humans can see 800-400nm, divided into red, orange, yellow, green, blue, blue, purple, infrared light greater than 800nm ​​and ultraviolet light less than 400nm. It is invisible to the eyes. Insects visually perceive light of 700-250nm, which is short-wavelength, and especially have a strong tendency to ultraviolet light of 400-330nm..."

There are a lot of blah blah, Chen Hu can't understand anyway, so he doesn't bother to listen, as long as he can complete the task, he won't pay attention to the light wavelengths and short light wavelengths above. As for the tourists in the live broadcast room, they appear There are many children's shoes with high knowledge.

"When I saw the spectrometer, I already guessed that it would have something to do with insects."

"Different wavelengths correspond to different insects. Let's all guess what the first insect is?"

"The first one should be mosquitoes, I think this has the most things!"

"I think it's a moth. Don't they all say that moths fly into flames? It's obviously phototaxis."

……

Apparently, many tourists were very interested. Chen Hu and Isabel held the lamps emitting ultraviolet light. After a while, the first insect flew over.

The first insect was neither a mosquito nor a moth, but a beetle with two long braids...well, it should be the antennae.

The beetle flew to Chen Hu's light tube and bumped it lightly a few times. Seeing this, Isabel turned on the recorder and said at the same time:

"This is a spotted beetle. It has phototaxis at night. Its appearance means that there are eucalyptus and oak trees nearby..."

There were a lot of Bala again, and Chen Hu didn't bother to listen, but the tourists in the live broadcast room became annoyed. This dog-Ri Tianniu would actually win the first place, it's really hateful!

Not long after, a few gray and white moths flew over and danced in front of the lamp tubes of the two of them. The tourists finally became excited when they saw this, and Isabel said very seriously:
"Mulberry borers are one of the important pests of mulberry trees. They lay eggs on mulberry trees and then pass through..."

Chen Hu looked at Isabel, explaining and recording at the same time, he had to admire this foreign girl, if this is an ordinary girl, seeing these beetles, moths and other things, I'm afraid she would have screamed in fright.

After all, he is a Ph.D. in zoology, let alone the amount of knowledge, even this courage is extraordinary, and then, under Yisha's signal, Chen Hu adjusted the spectrum of the light tube to blue.

After a while, countless mosquitoes flew over, and even Chen Hu felt his scalp tingle when he saw it, and then there was white light, which attracted some lamp moths, stem moths and so on again.

These attracted insects were phototaxis insects. During this process, the barrage in the live broadcast room never stopped.

"Fancy foot-picking young man: Do you dare to attract dung beetles? Dare you!"

"Donkeys who don't eat meat: Dung beetles have phototaxis? Are you a fucking idiot upstairs?"

"Xin Gen Bao Ding: Dung beetles are also called dung beetles. It is unclear whether they are phototaxis, but one of them, the one-horned stinky dung beetle, is phototaxis."

"Donkey who doesn't eat meat @心横宝丁: There is no picture to say it! I don't believe it!"

"The world of mortals will always be with you: +1 if you don't believe it"

"Yeah Big Brother: +2 if you don't believe me"

……

Apparently, a fierce war of words had already erupted in the live broadcast room. The light tube in Chen Hu's hand, which was emitting white light, really attracted a hard-shelled dung beetle to fly over after a while.

It was the legendary dung beetle who likes to drill elephant dung and roll balls. The appearance of this scene immediately brought an end to the war of words in the live broadcast room.

Seeing this, Chen Hu couldn't help smiling, so he said that hearing is believing, and seeing is believing. When you haven't seen the truth, it's better not to draw conclusions too early, especially in nature.

But human beings are a kind of high-level animals that care about face. Even if they see the truth, they may not admit it. Although the war of words is over, the barrage has not stopped.

"No one loves to go around in their hands: see? The dung beetle is here!"

"Bumpman: Does this face hurt?"

"Donkey that doesn't eat meat: It hurts! You say it's a dung beetle? I'm going to say it's a beetle!"

"The world of mortals is always with you: You are right! Unless you can prove that the insect is a dung beetle, we still don't believe it!"

"Yeah Big Brother: +1 if you don't believe me, let's see what you can do!"

"Old Popsicle, Big Popsicle: It's not easy, let Lord Tiger pull a pile of cakes, and you'll know after a while!"

"You can cry and laugh when you read a book: Yes! Lord Tiger smacked their papas and slapped them in the face!"

"The water is cold and fragile: La Baba +1"

……

poo?Chen Hu's face darkened instantly, but in the night, it didn't look very obvious, but the words of these fans made him feel bad.

Your war of words, just war of words, what are you doing by involving me?Pull your sister's papa!If it wasn't for Isabel's presence, Chen Hu would definitely yell at her.

Fortunately, when Isa saw the dung beetle, she couldn't help explaining:

"Dung beetles can use the phenomenon of moonlight polarization for positioning to help feeding. They have a certain degree of phototaxis. There are more than 2 kinds of dung beetles in the world... Most dung beetles are coprophagous and feed on animal feces. Scavenger' title."

As soon as these words came out, a new round of war of words was finally broken, but whether it was the winner or the loser, they were a little disappointed in their hearts. After all, they didn't see the scene of Lord Tiger pulling papa to attract dung beetles.

Seeing this, Chen Hu let out a sigh of relief. He almost spat out a mouthful of old blood just now, and then accompanied Isabelle to continue to attract insects with the spectrum. After about an hour, the two used five different kinds of insects in a row Spectrum, finally finished the study of insects in this area.

[Chain task: The host successfully helped Dr. Isa to complete the research topic of 'Phototactic Insects', and was rewarded with 1000 experience points. 】

Hearing the system prompt, Chen Hu's mood suddenly improved a lot, then he looked at Isabel and asked with a smile:

"Shall we go back to sleep?"
