"The second strategy is the method of prevention and control, if the big country cooks small fresh, the control of the locust plague is like controlling the water, it is better to block it than to sparse it, and after the locust plague is completed, then find a way to fight it, but it is just to make up for the loss."

"If we want to reduce the locust plague, or even solve the locust plague completely, we must let the people know how to prevent and control the ......"

"From ancient times to the present, the number of locust plagues is as numerous as a cow's hair, and they appear almost every year, and the minister has collected a large number of information on the growth of locusts and the records of locust plagues in previous dynasties, and has come to a conclusion."

Zhou Zhenwen talked about it and began to carefully introduce the living habits and growth characteristics of locusts.

Empress Liang Zhao and the ministers listened very carefully, and the Hubu Shangshu Jigu worked hard to write and constantly recorded what Zhou Zhenwen said.

"Locust plagues basically occur after droughts, when lakes dry up and become floods, and the arid, warm environment gives locusts the opportunity to multiply...... After summing up, the conditions required for the large-scale reproduction of locusts are: first, dry and water-deficient wasteland, second, land with gaps, and third, sparse vegetation cover, where these conditions are met, insect eggs are prone to appear, and locust larvae are multiplied in large numbers, forming locust plagues. ”

"Therefore, the second prevention and control method proposed by the minister is to completely eradicate the locust plague from several aspects."

"First of all, let the people go into the fields to look for small holes like beehives, and if they find them, dig them up with shovels to see if there are any locust eggs, and if they have, they immediately dig them up and burn them with fire."

"Secondly, you can plant some crops that locusts don't like to eat in locust plagues, such as soybeans, mung beans, black beans, sesame, cotton, buckwheat, ......."

"At the same time, let the people raise some chickens and ducks and other poultry, and one adult duck can eat hundreds of locusts a day......

"You can also use lime and straw ash to control it, and you can prevent locusts from eating it by applying these things to the crops......

Zhou Zhenwen said more than a dozen prevention and control methods in a breath, including the physical level, the biological level, and the chemical level, including almost most of the treatment methods he knew in his previous life.

This is also the method of prevention and control accumulated by China for 5,000 years.

"I see!"

"There is so much knowledge in locust control?"

"Taught!"

"If all the people in the world can learn, the locust plague will naturally not form a ......"

The ministers nodded their heads one after another, as if they were being taught.

Empress Liang Zhao also showed surprise, she didn't expect Zhou Zhenwen to have so many unique insights into the control of locusts?

The reason why the ministers were surprised and taught was that there was no system for the prevention and control of locusts in the Great Wilderness, and no officials wrote books on it, and to a large extent, they all relied on the spontaneous actions of the people and the cooperation of the government in governance.

This has also led to frequent locust plagues.

Because there is martial arts in this world, the people and officials also rely on the people who know martial arts, in the early stage of the locust plague, by the martial arts masters to carry out physical deworming, in this deworming mode, the people of this world, for other ways of deworming, the study is not enough.

In fact, this is related to the living environment and historical process of the two worlds.

In the world where Zhou Zhenwen is located, there is no martial arts, and there are no high-ranking martial arts masters, if you want to control locusts, you need to work hard from generation to generation, study the habits of locusts, kill insect eggs, and prevent the emergence of locust plagues.

These valuable governance experiences have been summed up only after bloody lessons.

Every locust plague is an unimaginable disaster and despair.

"Locusts have appeared in Qingzhou, and a large number of locusts are awakening and metamorphosing, before they are completely transformed, the imperial court should deal with them as soon as possible, and use the methods just mentioned by the minister to kill larvae and insect eggs in a large area to prevent the emergence of locust plagues that are difficult to suppress."

Zhou Zhenwen arched his hand and said in a deep voice.

The ministers nodded in agreement, thinking that what Zhou Zhenwen said was reasonable.

Empress Liang Zhao bowed her head slightly and looked at Zhou Zhenwen: "Zhou Aiqing said two strategies just now, what is the other strategy?" ”

Zhou Zhenwen thought for a while, and said one word: "Eat!" ”

"Eat?"

As soon as these words came out, the ministers' faces changed suddenly and they shuddered.

The thought of what locusts look like makes them scared and disgusted!!

Hubu Shangshu Jigu even said directly: "Scholar Zhou, locusts can't be eaten, they are poisonous!" ”

"To be precise, it is the formation of a plague of locusts, and the locusts that gather are poisonous!" Zhou Zhenwen glanced at the Hubu Shangshu Jigu and corrected.

"Are locusts that form plagues and gather into locusts poisonous?"

"What does that mean?"

"I also hope that Zhou University will teach you!"

Hubu Shangshu Jigu frowned slightly, bowed and asked.

"Locusts are very special creatures, they grow from eggs, they will undergo mutations, and after they become adults, there will be two situations."

"The first is the solitary locust, this kind of locust is also called nymphs, nymphs are non-venomous, people can eat, and chickens, ducks, terns and other animals, they also eat nymphs that have not yet become plagued. Many animals feed on locusts, which are highly nutritious insects that provide them with nutrients. ”

"And the second is the locusts that have gathered into a plague and began to devour crops and trees in a large area, after this locust gathers, the body will secrete a special substance, and the color on the body will change, becoming eye-catching, bright, black, yellow, red or other bright colors, the appearance will also become fierce, and the temperament will change greatly......"

"From being timid, gentle, and shy when living alone, to being irritable, aggressive, and having a great appetite......"

"This is also the origin of the plague of locusts."

"Therefore, the locusts that have not mutated can be eaten, after frying and roasting, the color and flavor are beautiful, but those locusts that change color are not edible, which contains poison, a small amount of food, may not be fatal, but once eaten in excess, it will be life-threatening, and those social locusts will be attacked after they will stimulate ferocity, enhance the toxicity in the body, and become deadly poison."

Zhou Zhenwen said the knowledge of locusts in a relatively simple and easy-to-understand way.

The locusts have a scientifically proven ability to defend themselves against swarms, synthesizing and releasing the compound phenylacetonitrile, a special organic compound, also known as benzyl cyanide, which is classified as a Class III precursor chemical.

When the social locusts are not threatened, the phenylacetonitrile in their bodies does not convert into the poison hydrocyanic acid, which only serves as an olfactory signal to warn predators. When a predator insists on attacking, the locusts immediately convert phenylacetonitrile into the poison hydrocyanic acid for defense.

Even when more than 60 social locusts mutate, their color and morphology change, and their appearance becomes more ferocious, aggressive, and aggressive.

"Scholar Zhou, well-read and strong-minded, has such a deep understanding of locusts, which really makes this official admire!" Tobe Shangshu Jigu bowed down, revealing a look of admiration.

"Ji Shangshu is polite!" Zhou Zhenwen nodded slightly.

Empress Liang Zhao thought about it for a while, and felt that this matter was feasible, but it was not easy to carry it out and let the people eat locusts.

After all, locusts are poisonous and deeply rooted in the hearts of the people, and if you want to change people's hearts, you can't just say something and give an order.

"Scholar Zhou, how do you think the people can let go of their scruples and eat locusts?" Empress Liang Zhao asked.

Zhou Zhenwen looked at the empress Liang Zhao and said in a deep voice: "If you want the people to believe that locusts are not poisonous, you must have a person of prestige to set an example and eat locusts in front of the people, so as to dispel the people's worries!" ”

"Who does the scholar think is suitable?" Empress Liang looked at Zhou Zhenwen's gaze, and her heart chuckled, and a bad premonition swelled.

Zhou Zhenwen smiled slightly, arched his hand, and said softly: "The minister thinks ...... Your Majesty is the most suitable! Your Majesty is the true Son of the Dragon, and he should be an example for all the people, if His Majesty eats locusts, then the people of the world will inevitably follow suit, and the locust plague will naturally cease to exist! ”

"What?"

"You let me eat locusts?"

Empress Liang Zhao's face was a little tense, this Zhou Zhenwen actually let her eat locusts?

This......
