水稻二化螟又叫水稻钻心虫.它以幼虫为害稻株,一代幼虫取食和蛀茎造成“枯鞘”和“枯心苗”,二代幼虫蛀茎造成水稻“白穗”.水稻二化螟多发生在丹东地区,近几年其它稻田也有发生.由于二代幼虫蛀茎为害造成白穗,常常被误认为水稻穗颈瘟病,造成防治上的失误.所以掌握水稻二化螟的形态特征、 Rice stem borer, also known as rice borer, which larvae damage rice plants, feeding and the first generation of larvae infestation and stem causes “dead shell” and “dead heart seedlings”, the second generation of larvae cause stems rice “white spike.” Rice two Stem borers mostly occur in Dandong area, and other paddy fields have also occurred in recent years .Because of the second generation larvae caused by stem damage caused by white spike, often mistaken for rice panicle blast, resulting in control errors. So grasp the rice borer morphology feature,
