摘要
为了对凤凰县烟蚜的适时治理提供参考,2008-2012年对该县烟蚜的越冬基数、迁飞及田间消长规律进行了调查。结果表明:有翅蚜迁飞高蜂主要集中在毎年5月上、中旬和6月中旬,且高峰期内的烟蚜迁飞数量最多;烟蚜种群消长除2010年呈双峰曲线外,其余4年均呈单峰曲线。建议,大田防治在5月中旬到6月中旬进行。
The overwintering base number, migration and growth and decline regulation of M. persicae from 2008 to 2012 were investigated to provide a referance for M. persicae control in Fenghuang County, Hunan. The results showed that the migration peaks of adult M. persicae were in the first ten-day period of May, the middle ten day period of May and the middle ten-day period of June mainly, and the migration quantity of adult M. persicae was maximum in the peak periods. The population growth and decline regulation presented a unimodal curve except for the bimodal curve in 2010. The measures to control M. persicae should be conducted from the middle ten-day period of May to the middle ten-day period of June.
