Starting from the northern region, wild bullfrogs in Jiangsu and Zhejiang provinces were quickly cleaned up.

These wild bullfrogs are either steamed at high temperatures to become prepared biomass power generation fuel, or they are collected by farmers to be sold as food, and none of them are spared.

In the process, Lin Han also cleaned up some other long-lived invasive animals, such as Fushou snails.

Although the lifespan of the Fushou snail is only more than a year, it is obviously a relatively long-lived existence compared to a pest of a few days and months.

Due to the large number of parasites in the body, cooking is more troublesome, and the chances of it being served on the table are generally less.

In addition, it is slow to act, and it is not easy to convene on a large scale. So after consideration, Lin Han finally chose to cooperate with local goose and duck farmers to let the geese and ducks eliminate the Fushou snails in the water and fields.

The pecking of geese and ducks was originally the main way to curb the snails.

Now the Fushou snail has been deprived of reproductive ability for life by the "eunuch buff", plus a certain degree of small-scale concentration, in a very short period of time, its number has been rapidly reduced.

All the invasive plants in Jiangsu and Zhejiang provinces, as well as most of the invasive animals, have been thoroughly cleaned up, and the effect is very significant.

Of course, there are a small number of invasive animals that Lin Han will not be able to completely solve for a while, such as the Brazilian turtle.

Although the Brazilian turtle is a famous short-lived ghost among turtle creatures, the thousand-year-old king and 80,000-year-old turtle, the Brazilian turtle is still a turtle no matter how short-lived it is, and it is no problem to live for one or two decades.

Although the eunuch buff can make it incapacitated, as a race, it obviously cannot die in a short period of time.

Take it to people to eat, this thing doesn't taste very good, and there is basically no market.

There is no way to take the iron armor of an adult Brazilian tortoise for poultry and livestock.

The lions and tigers in the zoo can kill such smaller turtles like swallowing melon seeds, but the lions and tigers obviously don't look down on them.

Collecting them to make fertilizer and generate electricity, with the speed of the Brazilian turtle's action, it is too troublesome to gather, and I am afraid it will take a lot of time to do it.

In the end, Lin Han had to temporarily let go of the Brazilian turtle. Anyway, they have collectively lost their reproductive capacity, and sooner or later they will all be extinct.

After all, the immediate priority is to clean up 30% of the country's invasive plants and animals within this year.

If you waste a lot of time to clean up a few bigwigs in the invasion circle, it will be too worthwhile.

Dong Quang Provincial Department of Health.

Between the corridors of the office building, a young man in a suit and leather shoes, holding a stack of documents in his hand, walked around and down to the door of the director's office.

"Knock knock. He knocked on the half-hidden door.

"Come in. ”

The young man entered the office and placed the document in his hand in front of Director Wei's desk.

"Director, this is the latest dengue fever epidemic risk monitoring report, please take a look. ”

Director Wei raised his hand to take off his black-rimmed glasses, and at the same time picked up the report and looked at it carefully.

"According to the report of the Epidemic Prevention and Control Committee, due to the introduction of mosquito strains implanted with Wolbachia newia, the risk of dengue fever epidemic this year has dropped to the lowest level since the founding of the People's Republic of China. The young man said in general.

Director Wei nodded: "So, dengue fever has been basically controlled in the province, and it will be difficult to re-epidemic in the future?"

"Yes. ”

Director Wei put down the report and said with a smile: "Professor Chen is worthy of being the youngest Changjiang scholar, and he has solved the problem so quickly. I thought I would have to wait two years. ”

Although dengue fever is only endemic, it is also lethal after all, and each outbreak will kill several people.

Human life is never a trivial matter.

Provincial and national leaders are concerned about dengue fever to some extent, and sometimes ask about it. If the epidemic is not resolved, and people die every year, the Dongguang Provincial Health Department will have to be collectively depressed.

Now, as long as the idiosyncratic mosquito species multiply and grow, the dengue virus will no longer have a place in Dongguang Province. Funds used to prevent and control dengue outbreaks can also be saved and used in other areas.

Nanhai, Hujian and other southern provinces will definitely follow suit and purchase mosquito strains for stocking. It didn't take long for dengue fever to be extinct throughout China.

Director Wei will undoubtedly become a pioneer in the eradication of dengue fever in China...... At least politically.

"I remember that in addition to the Institute of Microbiology of Peking University, Vientiane Technology Co., Ltd. in Handong Province and the School of Biology of CUHK were also involved in the research and development work. Is that so?" Director Wei seemed to remember something.

The young man nodded: "Peking University and Vientiane are responsible for the research and development of a new type of Wolbachia, and CUHK is responsible for the cultivation of mosquito strains." ”

Director Wei said: "Since the control effect is good, the remaining amount will be paid in full this month." ”

"In addition, I am going to hold a report meeting on dengue fever prevention and control at CUHK, and Peking University, Vientiane, and CUHK will all inform you, as well as the Nanhai and Hujian Provincial Health Departments, and invite some people to participate. ”

As soon as the young man was about to leave, Director Wei said again: "There is one more thing, in the name of the Dongguang Provincial Health Department, a public letter of thanks will be issued......

……

A few days later, a public letter of thanks in the name of the Dongguang Provincial Health Department began to circulate in major media outlets, and in addition to mainstream media, there were also some related news reports on the Internet.

The thank-you letter said three things to the effect. First of all, it is necessary to adhere to the party's leadership, adhere to the road of socialism with Chinese characteristics, and adhere to the ......

However, to get to the point, he said that Dongguang Province took the lead in overcoming dengue fever, and that the dengue fever epidemic is expected to be completely far away from China within three years, and has made a small contribution to the health and medical cause of all mankind.

Finally, on behalf of the people of Dong Quang Province, the Department of Health of Dong Quang Province expressed its gratitude to the three scientific research institutions of Peking University, Vientiane and CUHK, and invited them to participate in a report meeting on epidemic prevention and control to be held at CUHK......

Since this thank you letter is mainly disseminated in the official media, its influence is also more targeted. Various official institutions and scientific research institutions have responded greatly.

Vientiane has recently gained a reputation for its work on invasive species, and its reputation in scientific research, especially in the field of biotechnology, has become like a rocket.

So as soon as this letter of thanks came out, many universities and scientific research institutions couldn't help but feel a little pantothenic: how can it be Vientiane again......

Lin Han had just finished cleaning up invasive species in Jiangsu and Zhejiang provinces, and was preparing to continue in neighboring Hujian Province.

However, after reading this letter of thanks and the invitation to the report meeting, after some consideration, he changed his itinerary and went directly to Dongguang, a place known as a paradise for invasive species.
