根据历年调查资料,保定地区玉米螟卵赤眼蜂一般要在八月份以后者大量寄生于田间玉米螟卵,在此以前并未发现其活动。今年调查所得略有出入。八月份遇上水灾,因此这期间的工作只得暂告中断。后期继续观察的结果与往年一致。

According to the survey data over the years, Batriao corn borer Trichogramma usually in August after a large number of parasitic in the field corn borer eggs, in the past did not find its activity. This year’s survey a slight discrepancy. Floods hit August, so the work during this period was temporarily suspended. The result of continuous observation in the later period is the same as in previous years.
