Abstract:

China was a country of great amount of grassland, which accounted for 42 percent of total area. These grasslands have been an important base of the animal products, as well as high ecological and economic value. Grasshopper was one of biological disasters on the grasslands. If the density of grasshopper reached into a certain value, a large number of plants was grazed, which caused greatly harm to grassland animal husbandry and the ecological environment, even disaster. In recent years, climate change, overgrazing and irrational human activities lead to the appearance of grassland locusts in large pieces of area, therefore, anti-locust disaster and reduction lossless has became an important research topic of related department. According to literatures material in recent decades, in this study we generalized the main content and research focuses of grasshopper and plague of locusts during different periods in 20th century, overviews their achievements and developments, including the grasshopper classification, physiological, biochemical and biological characteristics, ecology, monitoring and forecasting, damage assessment, the prevention strategy, and the trendy research in the future etc., which supplied significant references for the further research of related study areas.
