The Chinese Academy of Sciences team reveals the secret! What is the chief culprit of locust plague?

The scientific research team of Chinese Academy of Sciences successfully found the culprit of locust plague, which is of great significance to change the countermeasures and technologies for locust control. This research result will change people's ideas and methods of preventing and controlling locust plague in many ways.

After decades of research, Chinese scientists have found that the latest iconic compound, 4- vinyl anisole Virginia (4), has great attraction to migratory locusts in different social development stages and genders, and positioned the olfactory receptor OR35 as the specific receptor of locust pyramidal receptors.

On August 13, the Chinese Academy of Sciences held a press conference on this achievement. The team's latest research comprehensively and fully identified and verified the chemical analysis, behavioral verification, neuroelectrophysiological recording, olfactory receptor recognition, gene knockout and field verification of migratory locust pheromones for the first time, and found and confirmed the 4va migratory locust pheromones. This is the first time that 4VA has been found in animals, not just insects.

Extended data:

Yunnan was "attacked" by locusts, and drones were dispatched urgently;

The yellow-ribbed bamboo locust is a locust that harms crops such as bamboo, banana and a small amount of corn. As of July 25th, a total of bamboo locust 140623 mu occurred in Yunnan * *. The State Forestry and Animal Husbandry Bureau and the Ministry of Agriculture and Rural Affairs have set up a work guidance group and rushed to the main locust-stricken areas in Jiangcheng County, Pu 'er, Yunnan Province to take preventive measures with the local people.

On the morning of July 26, in the cornfield of Qushui Town, Jiangcheng County, some corn leaves were eaten by Huangling bamboo locust, and the prevention and control personnel used drones to carry out anti-flying operations.

Jiang, deputy head of Jiangcheng County, Pu 'er City, Yunnan Province, said that drones will be used to stop locusts from flying along the border, and air interceptors will be set up to do their best to eliminate border locusts.

In the forest where traffic is inconvenient and drones and fog guns can't control, the expert group suggests using smoke agents to prevent leakage and repair, so as to prevent the remaining adults from mating and laying eggs and forming insect areas.

As of July 25th, the occurrence area of bamboo locust in Yunnan Province was 140623 mu, including woodland 107638 mu and agricultural land of 32985 mu, involving 28 townships in 7 counties of 3 states (cities). At present, the total treatment area has reached 354,667 mu.
