据观察一代二化螟化蛹地位的变动与水稻品种特性密切相关,在杂交水稻稻株上一代二化螟化蛹地位多在健株叶鞘内,所在叶位多在当时生育期稻株顶部以下2—8叶。调查测定:桂朝二号、泸科三号等杂交稻品
It is observed that the change of the pupal status of the two generations of rice stem borers is closely related to the characteristics of rice varieties.

Survey determination: Gui Chao II, Luke 3 and other hybrid rice products
