2020.20·The development of feed and forage | 饲料与牧草开发122 ·2020.202 草原害虫发生原因2.1 草原退化严重草原病虫害会对草地资源造成严重破坏，草地植被严重退化，草原沙漠化荒漠化现象严重，使植被覆盖面积越来越少，植被生物多样性遭受严重破坏，给害虫繁殖生长提供广阔空间。
在草场返青阶段，草原害虫会快速繁殖生长，破坏牧草生长，同时也会生产大量虫卵，造成草场害虫数量越来越多，对草原造成的危害日趋严重。
大范围的害虫危害使新生牧草被啃食殆尽，失去应有的利用价值，并且还会造成草场寸草不生，荒漠化进程进一步加重。
2.2 气候条件适合害虫生长草场进入返青期后，由于外界温度逐渐回升，草原环境湿润，空气新鲜，十分有利于草场害虫生长和繁殖。
在适宜的季节环境中，害虫数量会迅速增加，尤其是在春季降雨季节更有利于虫卵孵化。
在干旱季节，由于外界温度较高，十分适合蝗虫虫卵繁殖，并且很多害虫还可以通过大风向四周扩散，造成大面积草原被危害，对整个草原生态系统造成极为不利的影响[1]。
3 草原虫害生物和生态治理措施3.1 引入微孢子虫在草原害虫中，蝗虫是最常见种类，同时也是危害草原生态系统的常见虫害。
草原蝗虫虽然个体较小，但是数量庞大，一旦大范围传播流行，将会对整个草原生态系统造成毁灭性打击。
在草原蝗虫防控中，通过在草场引入微孢子虫，微孢子虫能附着在蝗虫身体上，并且长期存活，与蝗虫体内进行物质交换，留下新的孢子，生长发育过程中会以蝗虫体内的营养物质为食，并且具有一定传染性，防治蝗虫效果十分显著。
通过应用该种防治手段，草原蝗虫危害率会下降60%[2]。
3.2 利用苦参碱防治苦参碱主要是从植物中提取，对草原生态环境不会造成任何危害。
但是苦参碱中的黄酮类和微生物碱对蝗虫具有很好的消杀作用。
每公顷草原选择使用1%的苦参碱防控，能起到很好的防治蝗虫作用，减少蝗虫对草原造成危害。
