通过对甘肃省草原技术推广总站历年防蝗总结报告分析得出,甘肃草原蝗虫发生的重点区域是四大蝗区(祁连山蝗区、甘加蝗区、马鬃山蝗区、龙首山蝗区).蝗虫危害占甘肃省草原虫灾的50%以上,蝗虫种类有152种以上,是全国草原蝗虫的重点区域.一年中蝗虫多种类发生、不同时期发生,彻底防除难度大,干旱和草原退化加剧草原蝗虫大发生,因蝗制宜,创建草原蝗虫防治新机制,将一般防治和应急防治相结合,才能实现防控草原蝗灾的目标.

The occurrence and control situation of grassland locusts in Gansu Province were analyzed with the documents of several year's reports of Gansu Grassland Technology and Extension Station, and control strategies were summarized. There are 152 species of locusts, and the damaging area was more than 50% in whole nation. Therefore, grassland in Gansu is the key area in the locust's controlling. According to the intensity of the damage by locusts in Gansu, grassland in Gansu can be divided into four area: Qilian Mountain, Ganjia Mountain, Mazongshan Mountain and Longshoushan Mountain. Drought and decline of grassland enhance their lives, reproduction and damage. Since there are many locust' species, and damaging times are different for different species, controlling locusts become the most important work within the all pest control in grassland. Attempt to found some new mechanism to control locusts, and integrate common methods into special methods that used at emergency, grassland locusts would be finally controlled.
