| 摘 要： | 研究结果表明，美洲斑潜蝇危害四季豆时，虫情指数与产量损失率之间有极显正相关，其直线回归方程为Y＝0．7399＋1．0185X，r＝0．9980^**。防治指标：当虫情指数为9．504－19．725时，必须用药防治，控制其为害。

| Abstract: | The study result showed that the correlation between pest damage index and yield loss ratio was significantly positive when snap bean was damaged by Liriomyza sativae Blanchard, with the linear regression equation of Y=0.7399+1.0185X, r=0.9980 ** . The pest had to be controlled by pesticide when the pest damage index was up to 9.504-19.725. |
