| 摘 要： | 为了有效地进行草地蝗虫的防治，必须摸清其生长和繁殖与生态环境条件的关系，研究表明，气温对草地蝗虫影响较为明显的是在蝗卵越冬期和孵化期。降水量太多不利于草地蝗虫的发育，但适量降水因有利蝗蝻出土可能会增加蝗虫基数。青海湖Ⅱ级湖成阶地和构造台地更有利于蝗虫的繁育，此外，土壤的温度，质地及水分和盐分含量对草地蝗虫的发生和繁育也有一定影响。 |

| Abstract: | Qinghai Lake is located on the northeast Tibet Qinghai Plateau. Grasshopper is the major pest in the region around the Lake and there are ten grasshopper species with economical importance. The ecological study showed that air temperature had a significant effect on grasshopper egg survival and hitching. The low temperature during the winter killed some eggs and the mortality rate of eggs could be as high as 45%. Rainfall itself, especially the rainfall in May and June, and its interaction with soil temperature played an important role in the grasshopper hitching, which in turn affecting the number of grasshopper in the fields. It was found that the Lake formed terraces and the tectonic platforms were favourable for grasshopper reproduction. Egg survival and hitching of grasshopper were also affected by the soil conditions including soil temperature, soil water content, salt content and soil texture. |
