| 中文摘要: |
| 越南是草地贪夜蛾的重要虫源地,其发生情况对我国草地贪夜蛾的动态有明显影响。2019年9月15－21日,在越南山罗省安州县对草地贪夜蛾田间发生和为害情况进行了调查。结果表明,调查区域均发生草地贪夜蛾为害,玉米田间虫株率为50.7%,百株虫量为110.7头;不同玉米生长期(苗期和穗期)的虫株率和百株虫量差异显著,苗期大喇叭口期虫株率和百株虫量(84.9%和201.1头),显著高于苗期小喇叭口初期(53.2%和114.7头)和抽雄期(14.2%和16.2头);田间虫株率和百株虫量之间的幂函数模型为y=0.842 8x1.212 5。因此,要进一步加强与越南相关部门的合作,掌握越南草地贪夜蛾发生和为害动态,为我国草地贪夜蛾的监测与防控提供依据。 |

| Vietnam is an important source area of Spodoptera frugiperda, and its occurrence has a significant impact on the dynamics of S. frugiperda in China. On September 15-21, 2019, occurrence and damage of S. frugiperda in the corn field were surveyed in Yen Chau county of Son La province, Vietnam. The results showed S. frugiperda occurred in the investigation area in Vietnam, and the ratio of plant with larva was 50.7%, and the larva per 100 plants was 110.7 heads. The ratio of plant with larva and the larva per 100 plants showed significant differences among different corn developmental stages, and the ratio of plant with larva and the larva per 100 plants at big flare period (84.9% and 201.1 individuals) were significantly higher than those at small flare period (53.2% and 114.7 individuals) and those at anthesis period (14.2% and 16.2 individuals). The exponential function model of those two parameters was established as y=0.842 8x1.212 5. Therefore, we should strengthen cooperation with relevant departments in Vietnam, and to monitor the occurrence and damage dynamics of S. frugiperda in Vietnam, which is important for the monitoring and control of the pest in China. |
