为避免因使用化学农药污染草原生态环境,有效保护草原生物多样性和生态平衡,本文采用在草原上进行人工招引粉红椋鸟的试验方法,分析研究粉红椋鸟控制草原蝗虫的效果,试验结果表明,招引粉红椋鸟可有效控制草原蝗虫灾害的发生,在以招引巢为中心点,方圆半径为5 km范围内的蝗虫种群数量明显减低,防治效果达到90%以上,说明人工招引粉红椋鸟技术能够很好的控制草原蝗害的发生,这一研究为在草原上合理建设椋鸟招引巢提供了重要的数据支撑。

To avoid contamination of grassland ecological environment due to the use of chemical pesticides,and in order to effectively protect the grassland biodiversity and ecological balance,in this paper,we used the test method of artificial attracting Sturnus roseus to analyze the effect of locust control.The results showed that,attracting Sturnus roseus can effectively control the occurrence of locusts,the populations of grasshopper within a radius of 5 km was significantly decreased to attracting nest for the center,that over 90 percent of locust had been control.This shows that the technology of artificial attracting Sturnus roseus is a very good method of controlling the occurrence of grassland locusts.This resiut also provided an important data support for building the attracting nest properly in the grassland.
