摘要
河南县草原毛虫危害严重,是由于其气候和草场类型适宜草原毛虫的生长。本研究从2010—2012年对河南县的草原毛虫发生情况进行了为期三年的调查,并与三年的降水量和气温等进行相关性分析,结果显示两个气候因素都与草原毛虫的虫口密度呈正相关,两者相比气温因素对毛虫密度影响更大。
Harm of grassland caterpillar is very serious in Henan county, because of its climate and pasture type being suitable for the growth of grassland caterpillar. The happening situation of grassland caterpillar was investigated in Henan county from 2010 to 2012 , and correlation of grassland caterpillar happening and precipitation and temperature of three year was analyzed. The results showed that two climate factors and grassland caterpillar densities were positively correlated. The temperature factor has greater influence on density of caterpillar than precipitation.
