稻纵卷叶螟(Cnaphalocrocis medinalis Guenee)是湖南主要水稻害虫之一,每年第二,四代为害早、晚稻严重,间或第三代也可造成危害,以往是依靠施用化学农药进行防治,为了降低农业成本,减少农药残毒和环境污染,我们希望通过保护稻田天敌来控制纵卷叶螟的发生,从1980年5月起,曾对纵卷叶螟动虫的寄生天敌一纵卷叶螟绒茧蜂 Apantelescypris Nixon,进行生物学特性的初步观察。
Cnaphalocrocis medinalis Guenee is one of the major rice pests in Hunan Province. The second and fourth generation of pests suffer from early and late rice serious and the third or third generation can also cause harm. In the past, chemical pesticides were used to prevent and control them. In order to reduce Agricultural costs, pesticide residues and reduce pesticide residues and environmental pollution, we hope that by controlling the natural enemies of rice to control the occurrence of leaf roller, from May 1980 onwards, once on the leaf roller borer parasitic natural enemies of a leaf roll cashmere cocoon Bee Apantelescypris Nixon for preliminary observation of biological characteristics.
