[Background] Since June 28, the Yellow-ridged bamboo locusts have been found migrating and entering the country in Pu'erjiangcheng County, Xishuangbanna, and Mengla County, bordering Laos, and gradually spread to adjacent areas, causing local damage.
[Explanation] As of July 28, a total of 143,400 acres of yellow spine locust occurred in Yunnan province, and the province's cumulative area of prevention and control was 428,700 acres. A total of 54 groups of plant protection drones were mobilized to carry out 14,498 flight control operations, 13022 sprayers were put into operation, and 64,528 people were dispatched.

From June 28 to now, there are a total of 4 large (batch) 4 batches of bamboo locusts, which have migrated and entered the border through our border. So far, the situation of migration and entry, each batch, the main body The swarm of insects, the main part of the large-scale population of the main body, has been handled well by us.
[Explanation] The reporter learned in Jiahe Township, Jiangcheng County on the 30th that the township's industry is mainly based on 103,000 mu of rubber and 24,000 mu of tea. In addition, the villagers also planted corn and rice. Because the main food sources of the yellow ridge bamboo locust are bamboo and zongye reeds, and the prevention and control work is carried out in an orderly manner. As of that day, the yellow-ridged bamboo locusts caused minor damage to the crops in Jiahe Township.

All the ecological forest rangers, agricultural scientists, and village-level vanguards in each village were mobilized to form a grid of teams to monitor, monitor and supervise the locusts. If locusts are found, the masses will spontaneously organize extermination. Especially in the crop fields and corn fields, he sees and finds them, no matter how many he spontaneously controls them. If a large number is found, it is in groups, so we will report it to the county-level headquarters and use drones to carry out centralized culling.
[Explanation] It is understood that most farmers in Jiangcheng County are equipped with sprayers, and locust-killing drugs are uniformly distributed to the village. Once the traces of the yellow-ridged bamboo locusts are found, the locust-killing drugs will be delivered to the villagers for locust-killing operations as soon as possible. On the same day, along a certain highway in Jiahe Township, forest managers and villagers dealt with the discovered yellow-ridged bamboo locusts. After spraying the medicine, the locusts fell and died.

After the drone flies, we sometimes cooperate with the drone. The layer below the locusts killed at that time was piled up on the side of the road. Because there are so many on the top, the bottom will fall off after more than ten minutes after hitting it up. As long as it has been treated with (medicine), there are very few that it can survive, and now there are far fewer locusts than before.
[Explanation] The reporter learned from the Yunnan Forestry and Grassland Bureau that at present, Yunnan Province has established a province, city, county, township, village, group, and forest ranger pest monitoring network, and more than 3,000 people are invested every day to investigate hidden locust disasters; At the same time, the measures of "integration of ground and air, and implementation of regional policies" were adopted to jointly carry out prevention and control; a 155,500 mu of "agricultural land interception zone" was established in the townships bordering Jiangcheng and Mengla, and the overall prevention and control effect was obvious. From July 26 to 29, no large-scale migration of bamboo locusts has been found in Jiangcheng County for 4 consecutive days.

If bamboo locusts mean that they no longer migrate on a large scale, that is, when this condition is established, then according to the situation of internal non-proliferation, reducing the stock, that is, reducing the stock, and eliminating the stock. The next step is to concentrate on preventing the second migration, so it is expected that in 10 to 15 days, this swarm has already entered, and the remaining swarms can be effectively controlled.
[Explanation] The Yunnan Province Huangji bamboo locust prevention and control work expert group analyzed and judged that at present, the number of overseas bamboo locust populations is still large, and they are still moving in in batches, and the prevention and control situation is still severe.
