摘要
青海湖滨区草地蝗虫适生于海拔 31 0 0～ 350 0m ,植被盖度 60 %～ 85%的温性草原和高寒草原上坡度≤ 9℃的缓坡区 ;其种群数量主要受胚胎期和蝗蝻期温湿 (或温雨 )系数的影响 ,当胚胎期温湿系数为9%～ 1 4%、蝗蝻期温湿系数为 1 1 %～ 1 6%时 。
Grasshopper are suitable in the temperate grassland and alpine grassland with an elevation 3100～3500m,cover of vegetation reavhes to。60%～85% sloping ares(≤9°).Grasshoppers quantity were effected by temperature coefficient of embryonic and larva period.. Grasshoppers were occurring when temperature coefficient reached to 9%～14% during embryonic period and 11%～16% during larva period.
