采用试管观察及大田逐日捕捉，对发翅麦茎蜂进行了年生活史及其成虫田间消长动态的观察研究。得出，该虫在我省煌中县地区年发生一代。7月初孵活后，开始为害，于9月底入根茬内越冬，翌年6月上旬化蛹、羽化。通过田间调查研究，该成虫田间消长动态模拟方程为：为化学防治及引进天敌效果起指导作用。 Using tube observation and day-by-day field catching, the annual life history and the dynamics of the growth and decline of adults in the field were studied. It was concluded that the pest occurred in the area of ​​Huangzhong County in our province. Early July hatch, the beginning of damage, by the end of September into the stubble winter, the puppet in early June the following year, eclosion. Through the field investigation and research, the dynamic simulation equation of field growth and decline of the adult was as follows: to guide the chemical control and the introduction of natural enemies.
