Grassland locust regulation and control method

Abstract

The invention discloses a grassland locust regulation and control method, and belongs to the technical field of pest regulation and control. The grassland locust regulation and control method is characterized by comprising the following step of constructing a dominant vegetation community in a target area, wherein the dominant vegetation community is composed of dominant plants, and the dominant plants comprise polygala tenuifolia. According to the grassland locust regulation and control method, the locust density can be effectively reduced, and the locust population growth can be controlled.By the adoption of the regulation and control method, the purpose of effectively controlling locusts can be achieved only by conducting simple reseeding or weeding on the target area to be treated, the cost is low, environmental protection and effectiveness are achieved, local ecology is protected, and the regulation and control method can be widely applied and popularized in grassland areas.

Description

Technical field [0001] The present invention belongs to the field of pest regulation, and is specifically involved in a grasslands locust regulation method. Background technique [0002] Locust, commonly known as "grasshopper", a straight wings, including the Tetrigoidea, the Testacoidea, the Templer (Locustoidea), more than 10,000 species around the world, there are more than 1,000 kinds in my country, Distributed in the world of tropical, temperate meadows and desert areas. Specific species of grassland locusts include: white grain, short stars, Japanese diamonds, Asian small car locations. It is well known that locusts are agricultural pests, they will cause certain damage and harm to crops, grassland vegetation, and ecological environments. [0003] At present, the main methods taken by locust prevention and treatment are: chemical prevention and biological prevention. The means of chemical control mainly includes: using a chemical drug in Cartridge, Maraiulfonikozoine, to Fu...

AI Technical Summary

Problems solved by technology

[0004] The above methods have certain drawbacks. Chemical control has certain toxicity and will cause pollution to the environment; although biological control will not cause pollution, it is very difficult to find effective biological pesticides. The practice of stocking poultry is not advisable in some grassland areas with harsh natural environments; Large-scale application of microsporidia may kill some beneficial natural enemies of pests and cause ecological imbalance
