摘　　要：【目的】研究主要气象因子与草地螟种群数量变动的相关关系。【方法】2015和2016年通过诱虫灯,在哈巴河县研究主要气象因子对草地螟种群数量变动的影响,并进行系统分析。【结果】6月中旬和7月中旬草地螟越冬代成虫和第一代成虫达到种群数量的高峰期。逐步回归分析得知,平均温度、最高温度、最低温度、平均空气相对湿度、日照时数和降雨量是影响草地螟种群数量变动的主要气象因子。最高温度、最低温度的增大,限制草地螟数量的增多。【结论】哈巴河县6~8月的平均空气相对湿度和平均温度有利于草地螟生长发育,故该时期是草地螟在研究区域猖獗发生期。【Objective】To explore the relation between the main meteorological factors to the population fluctuation of Loxostege sticticalis.【Method】During the period of 2015 and 2016 the systematic analysis of the effects of the main meteorological factors on the population dynamics of L.sticticalis in the Habahe County was carried out.【Result】The population of L.sticticalis reached the peak between mid-June and mid-July.The regression analysis indicated that the average temperature,maximum and minimum temperature,relative air humidity,precipitation and sunshine hours were the main meteorological factors affecting the population fluctuation of L.sticticalis.The increase of maximum temperature and minimum temperature limited the increase of L.sticticalis.【Conclusion】The average temperature and relative humidity in Habahe County during June and August are conducive to the growth and development of L.sticticalis,and therefore L.sticticalis is the most rampant during this time.
