Green prevention and control method for desert grassland locusts

Abstract

The invention discloses a green prevention and control method for desert grassland locusts. The green prevention and control method comprises seven locust prevention and control methods such as a system investigation method, a natural enemy conservation method, a pheromone locust elimination method, an ecological locust elimination method, a physical locust elimination method, a poultry raising locust elimination method and an insecticidal fungus locust elimination method. Two to seven of the locust prevention and control methods are adopted to be combined and matched for use according to the practical situations of different regions and are used for comprehensively preventing and controlling the locusts in desert grassland. According to the green prevention and control method for the desert grassland locusts, the single prevention and control methods are adopted to be combined and integrated for comprehensively preventing and controlling the locusts in the desert grassland, use of chemical pesticides can be reduced by 100%, no chemical preparation is used, and therefore the aims of protecting grassland biodiversity and maintaining grassland ecosystem balance can be achieved; the economic income of farmers and herdsmen is effectively increased, injurious insect hazards are controlled, and meanwhile the living environment is protected.

Description

technical field [0001] The invention belongs to the technical field of pest control, and in particular relates to a green control method for locusts in desert grasslands. Background technique [0002] Locusts are destructive pests on farmland and grasslands. In recent years, with the abnormal climate, the ecological environment has been deteriorating. Grasshopper disasters in Inner Mongolia have broken out on a large scale year after year. One of the most serious biological disasters in the world, it has brought huge losses to the lives of farmers and herdsmen. The vegetation in the desert grassland is characterized by the fact that the vegetation itself is very scarce, and most of the desert grasslands are gramineous grasses that locusts like to eat, so the outbreak of locusts is extremely harmful to the desert grassland. At present, the prevention and control of locusts in the prior art is mainly based on the compounding of chemical pesticides or botanical pesticides and ...

AI Technical Summary

Problems solved by technology

At present, the prevention and control of locusts in the prior art is mainly based on the compounding of chemical pesticides or botanical pesticides and chemical pesticides. This locust control method in the prior art has the disadvantages of large pesticide residues, serious pollution of grassland soil, and harm to grasslands. There are many shortcomings such as biodiversity and serious damage to grassland ecosystems, so it is urgent to study a green control method for desert steppe locusts that can protect grassland biodiversity and maintain the balance of grassland ecosystems
