尖翅小卷叶蛾Bactra lancealana(H(?)bner)属卷叶蛾科小卷叶蛾亚科,是席草的主要害虫,江苏各席草产区均有发生,危害严重。据江苏仪征朴席乡1985年调查,由于此虫危害,席草平均减产二成以上,严重田块减产高达七成,已成为席草生产的一大威胁。为此,我们从1985年组织协作组,对尖翅小卷叶蛾的发生危害及其综合防治进行了系统研究。 研究方法 于1985年起在本省席草产区仪征朴席乡
Bactra lancealana (H (?) Bner) is a member of the genus Curvularia, which is the main pest of the grasshopper. All of the grass producing areas in Jiangsu have occurred and are seriously endangered. According to a survey conducted in 1985 by Yizheng Park Township in Jiangsu Province, as a result of this pest’s harm, the average output of grass seats dropped by more than 20%. As a result, the yield reduction of fields by as much as 70% has become a major threat to the production of grass seats. To this end, we organized a collaborative group in 1985, conducted a systematic study of the occurrence of Harpoonnaria involucrata and its integrated control. Methods of research Since 1985 in the province grass grass-producing area Yizheng Park Township
