摘要
通过对2005—2009年东疆地区棉蚜及气象数据的分析,得出了东疆地区棉蚜种群的消长规律和主要气象因子对棉蚜种群的影响。结果表明:6月是东疆地区棉蚜发生和危害的高峰时段,5—8月棉蚜种群数量变化极为剧烈,发生程度具有相邻年份间的相关性,气温是影响棉蚜种群发展的主要气象要素,低湿是东疆地区湿度影响棉蚜种群的主要方式,东疆地区主要降水时段与棉蚜严重发生时段不重合利于棉蚜的大发生,棉花的矮密化栽培模式削弱了大风对棉蚜的抑制作用。
This study analyzed Aphis Gossypii population and meteorological data from 2005 to 2009 in the eastern Xinjiang to find the population dynamics characteristics of Aphis Gossypii and the influence mechanism of meteorological factors to Aphis Gossypii.The result showed that the principal peak time of Aphis Gossypii occurring and harming was mainly in June in the eastern Xinjiang,the Aphis Gossypii population varied fiercely from May to August,the harming degree has correlation with the meteorological conditions in the last year and current year,air temperature was the main meteorological influence factor to Aphis Gossypii population,low humidity was the main way of humidity influence on Aphis Gossypii population in the eastern Xinjiang,the un-superposition between the main rainy period and the serious occurring period of Aphis Gossypii was advantageous to Aphis Gossypii breaking out.In addition,the shorter-closer cultivation pattern of cotton weakened the strong wind restraining Aphis Gossypii population.
