It's getting darker

The lights in the rice fields are even brighter.

The grasshoppers around them soon noticed the light in the rice field, and flew towards the glowing place.

One, two............

After a while, grasshoppers were seen flying all over the flashlight, and their numbers were so dense that they couldn't be counted at all.

"I'll go, I didn't expect this to really happen!" In just seven or eight minutes, so many grasshoppers gathered over, and Uncle Er Niu was also surprised when he saw it.

"Hehe, how is it? I'm not bad at this, right?" said Zhang Feng's wife selling melons and boasting about herself.

As if he hadn't heard, Uncle Er Niu took his flashlight and ran to the rice field on the side, taking action like this.

In a short time, almost all the people in the field learned this method.

So, in the wide field, the lights are dotted, and from a distance, it looks like the lights of thousands of homes, and it is also like the shining stars in the sky.

"Crazy, can you catch it?" Seeing more and more grasshoppers gathering around, Yiyi asked Zhang Feng with some anxiety.

"Alright, let's get going!"

Zhang Feng smiled, stood up, and walked towards the center of the rice field with Yiyi.

"Wow, that's a lot, madman, you see I caught two of them in one hand!"

Seeing that Yiyi was having so much fun, Zhang Feng nodded with a smile, but his hands were not idle, he kept flying in the air, and almost every time he shot, he could catch a grasshopper.

After five or six minutes of non-stop catching, the first wave of grasshoppers was finally caught, and the rest had escaped and disappeared into the vast night.

"Crazy, should we change places?"

"Okay, let's move over there!" The area of the rice field in front of me is not small, and it can be caught three or five times like this.

It has to be said that insects are too phototaxis, and as long as they see the light, they fly over as if they are flying to fight a fire.

After a few minutes, almost all the grasshoppers around the area gathered around the flashlight.

Zhang Feng and Yiyi also drew scoops according to the gourd, and hurriedly acted, seeing so many grasshoppers, Zhang Feng couldn't wait to give birth to a few more hands, wanting to catch all these grasshoppers.

As we all know, grasshoppers are locusts.

From ancient times to the present, locust plagues have been natural disasters that make people talk about changing colors, and in ancient times, they were as terrible as floods and droughts.

In modern times, although locust plagues occur much less frequently due to the use of chemical pesticides, they do occur occasionally, and each time they appear, they can bring huge losses.

Every time the locust plague appears, it is like a cloud covering the sky and the sun, and everywhere it passes, it will gnaw all the plants away, and it is no exaggeration to describe it with no grass left, no matter how beautiful the green mountains and green waters are, as soon as the locust plague arrives, it will become a barren mountain and bald mountain in an instant, and it is said that the locust can even gnaw off the reed poles mixed with mud that were used to bear the weight of people's houses many years ago, which shows how terrible it is.

However, no matter how terrible the locust plague is, it still can't stop our big foodie nation.

It is said that a few years ago, there was a locust plague in Lu Province, but the peasants there were not angry but happy, because they could earn hundreds of yuan every day just by catching locusts and selling them, which was simply good luck from heaven, which was unimaginable in previous times.

So at that time, when Zhang Feng saw the news, he also thought it was very interesting, thinking that locusts met us foodies, it was really eight lifetimes of mold, every time it appeared, it was almost just to send food to everyone, fried in vegetable oil, thinking about the crispy and refreshing deliciousness, it made people's mouths water.

And in September last year

At the same time as the locust plague occurred in Lu Province, there was also a locust plague in a certain area in southern Russia, there is a video showing that the locusts there cover the sky and the sun, and several locals are drowning in the boundless locust swarm, holding a large net to catch locusts, but with little effect, it is said that the Russian locust plague has swept many grasslands and agricultural areas in the south, leaving no grass in the place, so that the Russian agriculture and animal husbandry industry has suffered huge losses.

So why does the locust plague still appear in Russia, but it has not been able to develop in China in the past few decades? Is it just because we can eat locusts? Of course, the fact that we eat locusts is also a reason, but in fact, a bigger reason is that there are fewer tidal flats and swamps in the whole country.

The reason is that the swamps and tidal flats near rivers and lakes are the birthplaces of large-scale locust plagues, and the ancients summed up their experience, because the tidal flats and swamps are rich in water and grass, and they are the best habitat for locusts.

Zhang Feng still remembers that when he was a child, he once played on the river beach and found that there was a tall and dense aquatic weed, but when he got closer, he found that the tall aquatic weeds were full of locust larvae, these small locusts could not fly, because the wings had not yet grown, but the size was not small, it was already two or three centimeters long, and he could catch the next handful by brushing it along the aquatic weeds from the bottom to the top with his hand, and there could be more than ten of them, probably most people have not seen such a situation.

But since then, Zhang Feng has known that the tidal flat swamp area must be the birthplace of locust infestation, such as the locust plague in the Lu Province area just mentioned happened in the tidal flat swamp in that area.

Because of the increase in population, arable land has been almost maximized in China, and once the tidal flat swamp is transformed, it is usually good land, so the swamp and tidal flat area has been developed into farmland in China.

This leads to the loss of locusts to breed larvae in a large area, even if there are locusts growing on some relatively small river beaches, but they will not form a huge number, and it will not form a disaster, which is the main reason for the decline of locust plagues.

But there is another important reason, and that is the use of pesticides.

For example, the scale of the locust plague in Lu Province last time was not large, so most of the locusts that appeared were caught and sold for money, and were fried and eaten.

If you can't catch them, you can also spray pesticides to eliminate them, so modern Chinese have a way to deal with locusts.

However, the decrease in locusts also reflects another problem, that is, the environmental pollution is relatively more than before, industrial wastewater is discharged into some waters, resulting in some river beaches are polluted, it is difficult to grow aquatic plants, such waters can not grow locust larvae, coupled with the large use of pesticides, locusts entering the farmland will also be killed, of course, the number is not as large as before.

"Crazy, it's okay, you see our bottles are full!" Yiyi said happily to Zhang Feng with both hands holding her plastic bottle.

"Okay, let's go see Xiao Yue, where are they going?" Zhang Feng nodded, looked up, and saw Xiao Yue and a group of little children mingling in the field, chattering lively.

"Hee-hee, they're so lively over there!" Yiyi couldn't help but laugh when she saw it.
