| 摘 要： | 根据宜春和赣州稻区10年的虫情资料,分析了早稻白背飞虱主害代虫源性质.结果表明:宜春稻区早稻白背飞虱主害代虫源以5月下旬至6月上旬当地田间虫源和前期迁入虫源为主,近期迁入虫源亦有较大的补充作用.赣州稻区主害代虫源由5月下旬至6月上旬的田间虫源和近期迁入虫源构成,早期迁入虫源对主害代影响很小.

| Abstract: | According to the incidence information of Sogatella furcifera in the last ten years in Yichun and Ganzhou rice areas, the characteristics of insect-resources of main injurious generation of this pest in early rice were ana-lysed. Results indicated that the main injury came from the last-ten days of May to the first-ten days of June and the insect-resources in Yichun rice area were mainly the local field population and the immigrative insect-resources at early period, and were also supplemented by the immigrative insect-resources in recent term to a large extent. The insect-resources in Ganzhou rice area were similar to that of Yichun rice-area except the immigrative insect-resources was composed of a very small part. |
