| 摘 要： | 用盘拍法调查褐飞虱虫量的查获率仅在30％～70％之间，查获率的高低因虫口密度、水稻生育期及盘面涂抹粘胶与否而异。在所拟会的24个查获率回归方程中，极大部分的拟会效果是比较好的。当盘拍虫量在水试验范围以内时，代入相应的方程内，即能求出查获率，换算出实有虫数。

| Abstract: | The tracking down rate of the investigation of the population of Nilaparpata lugens (Stal) with the plant-flapping method, varing with the population density, rice growth period and the quality of plate surface (with or without glue), is between 30% and 70%. Most of the fitting results are good in 24 regression eqqation of the tracking down rate. Introducing the insects quantity flapped into the relevant equation, the tracking down rate is got, the real insects quantity can be converted. |
