Jiangcheng County is the main area for the occurrence of the yellow-spine bamboo locust disaster in Pu'er City. It can be said that at present, the affected area of Jiangcheng County accounts for the vast majority of the area of the yellow-spine bamboo locust disaster in Yunnan. Sun Tianmin said that at present, the prevention and control work is concentrated in the forest area. "This is mostly mountainous areas, not many green plains. The forest area is also the place where the yellow-spine bamboo locusts have the most footholds." How many yellow-spine bamboo locusts are in the woodland? Sun Tianmin said that after the drone sprayed the medicine, the yellow-ridged bamboo locusts in the woodland fell one after another, "on average an acre of land can drop 10 kg of locusts."
Mentioning the Manchurian locusts mentioned in many short videos, Sun Tianmin pointed out that the content of the video is not true, "The local locusts are not so large. This kind of locusts usually finish eating bamboo and then eat other crops. Crops and corn have basically caused no damage. Our work for so many days is not continuous. Recently, as soon as we discovered something, we immediately killed the medicine, so now we can see that the disaster is not a major disaster."
The disaster area is about 120,000 mu and the current situation is controllable
According to the information reported by the Forestry and Grassland Bureau of Yunnan Province and the Office of the Leading Group for the Prevention and Control of the Yellow Ridge Bamboo Locust Disaster in Pu'er City, Yunnan Province on July 10, as of July 7, the cumulative area of the Yellow Ridge Bamboo Locust in the whole Yunnan Province was 81,193 mu. Among them, moderate 2000 mu and severe (disaster) 1000 mu. On July 9, two days later, the occurrence area of the yellow-spine bamboo locust monitored in Pu'er City reached 117,600 mu.
However, through the monitoring information reported by the Puer Forestry and Grassland Bureau in recent days, the reporter of the Beijing News found that the spread rate of the yellow-ridged bamboo locust has decreased. According to the latest report on July 12, a total of 119,200 acres of bamboo locust disasters occurred in Pu'er City. Compared with the figures reported on the 9th, the area affected by locust disasters increased only slightly. According to reports, the density of locusts in the severely endangered areas reached 200-800 heads per square meter. The main hazards were bamboo, plantain, rice dumplings and a small amount of corn.
In addition, according to the report, experts have determined that the rate of locust migration and the spread of insects in the country has slowed. The use of drones to spray pesticides has further reduced the density of insect populations and reduced the damage of locusts, but the pressure for prevention and control still exists. Next, we still need to strengthen the monitoring of pests at the border and prepare for emergency treatment.
