Chapter 380: Natural enemy insects transform into forestry surprises
Nanping, Fujian Province.
"Boom!"
"Boom!"
With loud sounds in the sky, in an instant, biological agents were sprayed into the forest.
On a mountain platform.
Xu Xuenong looked at the helicopter in the distance, "This is really an anti-aircraft cannon to kill mosquitoes."
"Haha..."
Nanping Forest Pest Control and Quarantine Standing Zhou Lei smiled and said, "As long as it works, as long as it can kill the pine caterpillars, it is a good idea."
At this time, several drones also returned from the distant sky and were working Under the operation of the personnel, ammunition was replenished.
This ammunition is different from the biological missiles at the quarantine station, but a gift carefully prepared by the Natural Enemy Center for the pine caterpillars: ladybugs, chafers, and pine caterpillars Trichogramma.
Pine caterpillars, known as forest psoriasis, are the most widely distributed forest pests in my country.
Pine caterpillars feed on pine needles of pine trees. Under stable conditions, they generally do not cause serious harm.
But when the insect population density is too high, the pine needles may be eaten away.
In mild cases, it affects the growth of pine tree volume, rosin and seed production, and in severe cases, it can cause the death of large pine trees.
In Nanping, due to the decrease of natural forests and the increase of artificial pure forests, pine caterpillars frequently break out and cause harm.
In Nanping city alone, the affected forest area exceeds 3 million acres.
This time of year is also a critical period for Zhou Lei and others to organize aircraft to control pests.
Natural enemy pest control has been used in Nanping in the past, but it was always as an auxiliary method in comprehensive management.
But Zhou Lei is still happy to see Jiahe take the initiative to ask for help.
He looked at the staff loading the drone with ammunition, and then at Xu Xuenong.
"Mr. Xu, if the monitoring data does not improve in a week at most, the test area will have to be sprayed on a large scale, and all the released bugs may be killed by then."
The experimental area given to the Natural Enemy Center is also one of the most infested areas.
Zhou Lei believes that helicopters will still have to use helicopters to fire artillery in a week. The natural enemies dropped by drones are not effective.
Xu Xuenong smiled, "One week is enough."
"It is a good thing to have confidence." Zhou Lei said: "But if the effect is not good, the bureau will not pay."
The quarantine station is an institution under the Municipal Forestry Bureau, and the Natural Enemy Center is established through the Forestry Bureau Come to your door.
"It doesn't matter if it's free. What we planned from the beginning was the first free service."
Xu Xuenong stopped mentioning this and turned around and said: "By the way, Webmaster Zhou, Song I have to ask you to decide on the control area for Monochamus as soon as possible.”
“Then we have to look at the effect of the pine caterpillar control. If it doesn’t work, it will be gone.”
"Then let's wait and see."
Xu Xuenong knew clearly that the quarantine station still had no confidence in using pests to control pests.
With the help of the plant protection and aerial control team of Donghe Agricultural Machinery, the Natural Enemy Center completed the aerial control of pine caterpillars in a small town covering more than 1,500 acres in one day.
After it was completed, the Natural Enemy Center did not just wait for the result.
Instead, he led the team and rushed to the next point without stopping.
Zhou Lei also returned to the city and went to the Forestry Bureau to report on the aerial defense work to the leaders in charge.
The leader in charge asked: "What do you think after reading Jiahe's pest control method?"
"It can be used as an auxiliary method." Zhou Lei truthfully told what he saw and heard. Again, "The advantage is low cost, but the effect is uncertain."
The leader nodded, "How low is the cost?"
"The same financial funding should be able to cover all serious pests District prevention and control.”
The leader looked at Zhou Lei in surprise. Lack of funds and unclear entities for forestry pest control were common problems everywhere, and there were wranglings every year.
Zhou Lei recalled the entire governance process.
“Insects + UAV flight defense + personnel are the main components of the cost. Compared with the cost of helicopter gunfire, it saves at least one-third.”
The leader pondered: “ You have to follow up on this matter and confirm it, and I will report it to the provincial department.”
…
In addition to Nanping, Longyan, Sanming, and Ningde, three prefecture-level cities that are also suffering from pine caterpillar damage, have also set up aerial defense locations.
In a few days, Xu Xuenong and his team were exhausted from moving around.
After completing the final bee ball delivery in Longyan, Xu Xuenong finally breathed a sigh of relief and looked at the mobile operators with gratitude.
“Thank you everyone this time. Fortunately, I can fly and defend, so I don’t have to travel across mountains and rivers, otherwise I would collapse.”
“You’re welcome, Mr. Xu.”
The organic player said: "Natural enemy insects and drone flight defense are a perfect match. If Mr. Xu can develop this market, it will be a good thing for us."
"Yes, this can easily reach millions of acres. In the future, Feifang will have to earn more money.”
“Well, the only regret is that I didn’t get the feast that Mr. Xu said.”
“What feast?” br>
Several mobile phone operators looked at the sighing one in confusion. Even Xu Xuenong was attracted. His food these days is pretty good, right?
"Pine longhorn beetle!" the operator laughed and said: "Mr. Xu said that the protein of its larvae is six times that of beef. If we catch them all and fry them, the forest and I will be healthy."
< br>Everyone laughed.
"Okay, next time I will definitely meet your request and catch the beetle larvae for you with my own hands."
"Okay, if you can catch it, I will dare to eat it."
"Should I arrest two Fujianese for you?"
"Hahaha..."
At this moment, Xu Xuenong received a call. After answering it for a while, he started laughing.
After hanging up the phone, Xu Xuenong said with a smile: "Thank you brothers, the pine beetle is here."
Someone laughed sinisterly, "Now a certain People’s feast is in order”
…
Nanping, Wuyishan National Forest Park.
Wang Keke, the director of the Park Management Bureau, held a small test tube in his hand and asked doubtfully:
"This swollen-legged wasp is so small, smaller than the size of a long-legged beetle. 1%, can it definitely kill the beetle?”
“Of course, this is the beetle’s nemesis,” Xu Xuenong said with a smile: “Like Trichogramma, the swollen-legged wasp is also controlled by parasitism.
Although it is small, the swollen-legged wasp can recognize the scent of the long-legged beetle and follow its "path" to find the larvae and pupae of the long-legged beetle.
Use its bee needle to inject a biological anesthetic into the larvae to paralyze the larvae, and then lay eggs on its surface.
After the bee eggs hatch, the young bees suck the nutrients of the larvae, causing the beetle to die..."
Wang Technology marveled: “Has current technology developed to this extent? ”
“This is not our first initiative. Many domestic institutions have conducted research in this area. "
Xu Xuenong said to the many experts and leaders who came to visit this launch, "But we are confident that Jiahe's swollen-legged wasp is one of the best. ”
"We have already learned Jiahe's technology on pine caterpillars."
The leader in charge of the Forestry Bureau stood up and said: "In a week, the forest area where scarabs, ladybugs, pine caterpillars and Trichogramma were released, the insect population The density is greatly reduced.
The effect is not slower than that of a cannon. This is a real biological missile!"
Zhou Lei from Nanping Forest Pest Control and Quarantine Station, and The forecasting and reporting center that participated in the aerial defense of natural enemies was also deeply touched.
This period is the peak hatching period for pests, with hundreds of millions of pine caterpillars being born every day.
However, after the release of Jiahe's natural enemy insects, within a few days, the pine caterpillars seemed to disappear en masse. How many eggs have to be killed in one day!
They also have more confidence in Jiahe’s natural enemies, insects.
After counting the results, Nanping reported to the top immediately.
This attracted the attention of the provincial department, as well as the Forest Protection Institute of the Academy of Forestry and other units.
After confirming that it was true, they immediately asked Jiahe to increase the release of natural enemy insects.
The annual forestry pest control funds are limited, and the focus of prevention and control is also on those areas with serious harm, and fish often slip through the net.
The low cost of natural enemy control can provide wider coverage, and reducing the insect population base next year is also more conducive to the long-term stability of the ecosystem.
“The new natural enemy insects are being transported urgently. It only takes one day to fly them over.”
Xu Xuenong glanced at the platform on the mountain, and the flight defense team was also ready.
"Start releasing the swollen-legged bees."
Following his voice, a dozen drones took off almost at the same time and flew according to their respective planned areas.
Xu Xuenong was on the sidelines explaining key points such as where to put the fish, how many heads to put in one acre and so on.
Experts and cadres can also see the image data dropped by the drone through supporting equipment.
They were all surprised.
Combining drones with natural enemies of insects, the efficiency and cost are terrifying!
After the launch, the experts did not leave immediately, but stayed in Wuyi Mountain for two days.
In the past two days,
Huang Huangshui, director of the Forest Protection Research Institute of the Provincial Academy of Forestry, visited Wuyi Mountain.
In the forest, I found pine trees and poplar trees that were harmed by the pine beetle.
Longhorn beetles like to burrow into tree trunks by drilling holes or drilling holes.
In this way, it is very difficult to kill the pine longhorn beetle, whether using pesticides or manual removal.
However, if there is no effective control, a tree will be eaten up in a few years, and some will even die.
During two days of experimental observation, Huang Huangshui and other experts dissected more than fifty sections of branches that had been punched.
On almost every piece of wood, traces of newly bred swollen-legged wasps were found. The swollen-legged wasps as big as rice grains were crawling around the beetle host.
This makes the expert team extremely excited!
“The effect is incredible!”
“True beetle nemesis!”
“Everything comes down!”
Continuously Experts lamented that experience tells them that biological control is a long-term process and cannot be achieved overnight.
But what is the swollen-legged wasp in front of me?
This fuck is the beetle’s father!
It will be cured to death!
After two days of sorting out the information, Golden Water made a report to the State Forestry Administration on behalf of the province.
The swollen-legged wasp is not a mystery. The State Forestry Administration is very familiar with it, especially Wu Jian, the chief engineer of the Afforestation Department.
Because it was he and the pioneer Professor Xiao Gangrou who identified and named the swollen-legged wasp.
In 1983, he and Professor Xiao Gangrou published a paper: "An Effective Natural Enemy for the Prevention and Control of Longhorned Beetles: Guan's Swollen-legged Wasp".
However, more than 20 years have passed, and the application of swollen-legged bees in actual production is still rare.
The reason is that the effect is not obvious. In the laboratory, the cultivated swollen-legged wasps can parasitize the long beetle larvae.
But once you leave the laboratory, you will always encounter various problems.
But now someone told Wu Jian that the swollen-legged wasp was so powerful in actual production that the beetle larvae hiding in tree holes had nowhere to hide.
Wu Jian believed that Golden Water would not make a joke about this matter, but he still confirmed again,
"Is the effect really that outstanding?"
"I saw it with my own eyes, Wu Gong, I have sent you all the information.”
After Wu Jian read it, the figure of the swollen-legged wasp still appeared repeatedly in his mind. Just through the photo, he felt that there was something different about the swollen-legged wasp. .
It must be a carefully selected variety.
…
A few days later, the second batch of natural enemy insects such as Trichogramma wasps, swollen-legged wasps, scarabs, velvet beetles, and pine beetles from the Natural Enemy Center arrived in Fujian Province. .
The efficiency and speed of prevention and treatment are also visible to the naked eye.
“There are about 100 swollen-legged wasps in one tube, excluding transportation and release. The average price is 0.1 yuan/head. This is a very affordable price, Mr. Yan.”
Xu Xuenong suddenly started a business in Fujian Province, mainly because many forestry departments heard about it.
Nanping Hulushan State-owned Forest Farm is just one of them.
Director Yan stared at Xu Xuenong, "The forest farm has a total of 67,000 acres, and one management per acre costs six to seven hundred thousand. There is also investment, which is also very costly. Mr. Xu, can you give me a cheaper price?" Click."
"You think I'm stupid!"
Xu Xuenong said angrily: "The Hulushan Forest Farm is full of beetles? >
It's just a few thousand acres, and it only costs tens of thousands of dollars.
Also, you really don’t need drones? "
Director Yan said: "We have let the swollen-legged bees go before, and the effect will be better if they are artificially tied to the tree trunk. ”
“In fact, the effect is the same. "Xu Xuenong muttered, but the other party insisted that there was nothing he could do, "Okay, the packaging seems to need more design. ”
There are still many forest farms that insist on manual stocking.
After Xu Xuenong investigated, he discovered that the forest farm also supported many employees, and the drone deployment would only add a cost.
He could only mourn for a second of silence for the flying defense team. It seemed that the forestry flying defense team also earned hard-earned money.
During this period, he was reluctant to accept orders in Fujian Province.
The more orders, the lower the production cost of natural enemy insects.
A tube sells for 10 yuan, but the actual production cost of the natural enemy factory of swollen-legged wasps has been controlled to less than 2 yuan/tube.
5 times the profit is a huge profit.
The forest farm has also made a profit. The cost of prevention and control is more than ten yuan per acre. Compared with spraying pesticides, the cost of prevention and treatment is greatly reduced.
The key is to spray pesticides to treat the symptoms rather than the root cause, and it needs to be done every year;
The swollen-legged wasps can continue to reproduce and multiply after being released once, and the number of swollen-legged wasp larvae will also increase with the day. The number of cattle has decreased.
A single placement can guarantee worry-free results for several years.
This is a win-win, both sides win.
Xu Xuenong dreamed of getting rich for a while, and suddenly the phone rang.
At first glance, yo, it’s the boss, he has a weird nose.
"Hey, boss..."
"I'm in a good mood." Guo Yang joked: "It seems that the development in Fujian Province is going well. That's right, the State Forestry Administration has called me. Here I am.”
"It's not bad, I've received a lot of orders..."
Suddenly, Xu Xuenong reacted, "Did the State Forestry Administration call the boss?"
"Wu Jian, the chief engineer of the Afforestation Department, knows Right?"
"Yes, the big boss of forest insects and forest protection." Xu Xuenong opened his mouth in surprise, "Why is he calling you, boss?"
