摘要
观察2016年夏季深渡镇松毛虫种群动态,分析在适宜的气候条件下,当天敌减少、食物丰富而林业技术措施又跟不上时的暴发过程,指出夏季气温小幅升高对松毛虫生长发育的促进作用以及防治松毛虫的对策。
In this paper the population dynamics of Dendrolimus punctatus in Shedu Township in summer,2016 were observed and an analysis was made on the outbreak process in suitable climatic conditions with fewer natural enemies,abundant food and lack of technical measures. It was pointed out that a slight temperature rise in summer would promote growth and development of Dendrolimus punctatus and some control measures were presented.
