通过连续2a的系统普查,初步查明嘉祥县共有土蝗17种,分属2总科,6科,15属。同时,摸清了土蝗的优势种类、分布区域及一些发生规律;不同生态环境条件下其优势种分布明显不同;地形、地貌及植被覆盖度对土蝗发生有明显的影响。
Through continuous census of 2a system, we initially identified 17 species of soil locusts in Jiaxiang County, belonging to 2 families, 6 families and 15 genera. At the same time, the dominant species, distribution area and some occurrence rules of soil locusts were found out. The distribution of dominant species was obviously different under different ecological environment conditions. The topography, landform and vegetation coverage had a significant impact on soil locust occurrence.
