粘虫(Leucania Separata Waiker)是暴食性害虫。目前我省粘虫测报工作还以单站短期预报为主,大范围地进行区域性的异地数理统计预报尚无实践。所以研究我省二代粘虫区与三代粘虫区的关系,建立中长期异地预报的数学预测模式,对研究我省范围的粘虫发生消长规律,对指导生产防治工 Leucania Separata Waiker is a binge-eating pest. At present, the survey on armyworm in our province also focuses on the short-term forecast of single stations. It is not yet practiced to carry out a large-scale regional statistical forecast of remote maths. Therefore, we study the relationship between the second generation armyworm area and the third generation armyworm area in our province, and establish the mathematical forecasting model in the long-term and off-site forecasting. It is of great significance to study the growth and decline of the armyworm in our province,
