| 中文摘要: |
| 根据气象要素的变化具有季节承继关系,通过白背飞虱的虫情指标(始见期、迁入虫量及第五(2)代虫量)与冬春以来气候因子的相关分析,发现前期温度及降水因子是影响白背飞虱迁入、降落和在栖息地发生、危害程度的主要因子,且影响具有区域性和阶段性。在此研究基础上,建立了白背飞虱虫情指标的气象预报模型,其拟合和预测效果较好。

| 英文摘要: |
| Based on gradual variation of weather elements with seasons, this article analyzes the relationship between the population index (occurrence, ingoing quantity and the quantity of the fifth generation) and weather factors, especially climate elements in winter and spring. It was found that the factors of temperature and precipitation in the previous phase have strong influence on ingoing, landing, occurrence and injures caused by WBPH at the landing sites. On the other hand, the influence was characterized by changing with regions and phases. Furthermore, several weather models have been developed to predict the population index and good results have been obtained. These models can be applied in operation.
