Experiments with sausages? Is it to test the chemical composition of sausages?

If it is food surveillance, people from the health department should go to the market to take samples, instead of Li Bai buying sausages in the small supermarket in the center.

It's not to test the sausages, it's to use the sausages for other purposes, is it to be used as bait?

"Is it for catching small animals?" is the emergency team going to catch rats again?" asked Lin Xiaoxiao.

"Half of the guess is to catch small animals, but not rats, to catch red fire ants. ”

Lin Xiaoxiao searched for information about red fire ants in his mind, and this small animal should belong to a type of ant, not a native species of China, but an invasive species.

"Is there a red fire ant infestation in our Yunhai City?"

"Well, the scope of the invasion is not clear at the moment, and we are going to investigate. ”

"I want to go too. Lin Xiaoxiao volunteered.

Lin Xiaoxiao is a personality who loves to join in the fun, and this is the first time that there has been a biological invasion of red fire ants in Yunhai City, so she must follow to see such an exciting and exciting thing.

Seeing that Li Bai was a little hesitant, Lin Xiaoxiao immediately explained, "My exam today has ended, and I am an intern at our Center for Disease Control and Prevention, so I will not violate the rules by bringing it." ”

Li Bai smiled, "Okay, you can follow, but you have to take good precautions." ”

After settling the account, the two people passed through the central compound and went to the shunting car under the emergency warehouse, and found that several members of the emergency team had gathered here.

When everyone saw Lin Xiaoxiao following Li Bai's side, they all laughed strangely.

Yu Fei: "Xiaoxiao, why are you here? Is the exam over?"

"Well, it's just over, I'm going to catch red fire ants with you. ”

Gao Meng: "Red fire ants bite very painfully, you have to be prepared." ”

"Well, like you, I wear a special hazmat suit. ”

Yang Le: "Xiaoxiao is really diligent, no wonder our boss likes you so much." ”

Lin Xiaoxiao was stunned.

Li Bai glared at Yang Le.

Yang Le immediately changed his words, "I mean that our leader admires you very much, catching red fire ants, bringing you with you for such a difficult task shows that you have strong professional ability." ”

Zhang Lin changed the subject, "Boss, why are you buying sausages?"

"It's bait for catching red fire ants. Let's go first, and talk about the content of this on-site flow on the way. ”

Driving to Oasis Park Road, Li Bai introduced the action plan.

"The main purpose of our survey is to find out the anthill density and insect population density in Oasis Park and several surrounding residential areas.

Just now, I have sent the "Red Fire Ant Epidemic Monitoring Regulations" to the group of our emergency response team, everyone has a look, and the specific actions are carried out in accordance with the standards.

As for the anthill density survey, I have drawn up three routes that pass through Oasis Park, six surrounding residential areas and the main street, and the marked maps have been posted in the group.

When the insect population density is investigated, sausages are used as bait, and red fire ants and worker ants are lured by the trapping method.

Is it clear to everyone?"

Yu Fei was the first to ask, "How do we divide the labor of the three inspection routes?"

"Yu Fei and Gao Meng are in a group, Zhang Lin and Yang Le are in a group, and Lin Xiaoxiao and I are in a group, after checking the density of anthills and insect populations, we will coordinate the help of community personnel in the next ant extermination work. ”

Yang Le looked through the red fire ant epidemic monitoring procedures in his mobile phone, saw the insect population density survey, and asked, "I didn't understand this specific operation." ”

Li Bai: "When I get to the location, I will demonstrate the operation process on the spot." ”

Soon to the Oasis Park.

The disease control team carried a bunch of tools to the lawn first, and Li Bai taught on the spot.

He opened a sausage, took out a bamboo skewer, and said as he made it, "First clean up the weeds near the bait point, the sausage we brought is two centimeters in diameter, cut into small pieces one centimeter thick and wear on the bamboo skewer, and then make the ham sausage close to the ground, not in contact with the surrounding grass, after 30 minutes, collect the red fire ant worker ants on the bait into a petri dish filled with alcohol, count the number, and record the surface temperature and humidity."

Today is a sunny day, suitable for placing bait, and the bait placement time is from 8 am to 17 pm, each sample site survey 500 square meters, set up 5 baits, bait spacing more than 10 meters. ”

The operation seems simple, but you need to be careful and pay attention to protection from being bitten by red fire ants.

The three component heads went into action.

Lin Xiaoxiao followed Li Bai's side, the first time he watched him operate, the second time he was able to operate independently.

Their group is in charge of the Oasis Park, which has many ant mounds in the lawn and a large number of dark red ants on the surface.

When Lin Xiaoxiao sets up the bait, try not to disturb the red fire ants.

Sometimes if you accidentally step on a piece of turf, a large number of red fire ants will gush out of it.

Lin Xiaoxiao stared at the turf and asked, "These grasses look strange, they don't look like they grow out of the ground." ”

"This is the ditch leaf knotweed, also called Manila grass, artificially planted turf, transported here from the outside, spread on the yellow soil of the park, usually take good care of it, otherwise it is easy to wither and turn yellow. ”

"Director Li, we have been checking for so long, and there are the most anthills of red fire ants in this lawn in the park, is it related to this turf?" Lin Xiaoxiao analyzed.

"It is very likely that this park was newly built last year, and the seedlings and turf are all new species, and if the seedlings and turf carry red fire ants, the lack of natural enemies of red fire ants in the local area can easily multiply and cause biological invasions. ”

"What then?"

"After this is over, contact the garden construction department to check the information, and you can know where these seedlings and turf come from. ”

Investigate the density of anthills and insect populations, and the next step is to exterminate ants.

Li Bai took out different ant killer baits and began to spray them.

The emergency response team has been working in Oasis Park and surrounding residential areas for nearly a day, and it is almost evening after spraying medicine.

A few people returned to the shunting car, and Yang Le let out a long sigh, "Oops, I'm tired of my old waist, and I'm finally done." ”

Yu Fei made up for it, "Red fire ants are tenacious in life, and it is not a matter of a day or two to completely eradicate them, and some will be busy in the future." ”

Yang Le looked up to the sky and sighed, "The Jade Emperor, the Buddha of the Western Heavens, and the gods from all walks of life...... Help me, I don't want to deal with these little ants every day. ”

Li Bai felt strange, although Yang Le usually gossiped, he never complained about his work, what happened this time?

"Yang Le, where were you bitten by red fire ants?" Li Bai suddenly asked.

"Ankle ......" Before he finished speaking, Yang Le suddenly reacted, he didn't tell anyone that he was bitten by red fire ants when he was acting just now, how did Li Bai know?

"Chief, how do you know?"

Yang Le saw that he couldn't hide it, so he simply pulled up his trouser legs.

He already had three blisters on his ankles, and the blisters were red and swollen as a symptom of being bitten by red fire ants.

Several members of the disease control team surrounded Yang Le and carefully observed the blisters on Yang Le's legs.

Gao Meng gloated, "The ant exterminator was bitten by the ants, Yang Le, you can do it, the protective clothing is worn in vain." ”

Yang Le was angry, "Gao Meng, do you still have some love from your colleagues?
