通过对蒙城县植保站27a黏虫资料的研究分析,可以看出一代黏虫多年雌虫率的平均值应是最佳雌虫率。一代黏虫种群的雌虫率愈接近最佳雌虫率,其下代种群数量趋势指数则越高;反之,则较低。
Through the study and analysis of the 27a sticking insect information in the plant protection station in Mengcheng County, it can be seen that the average of many generations of the armyworm should be the best female. The results showed that the female rate of one generation of armyworm population closer to the best female rate, the trend index of the next generation population number is higher; otherwise, it is lower.
