| Abstract: | The correlation between the attacking rate and population density of Hylobitelus xiaoi larva was studied and the mathematics model was optimized.It could be described as Y=1/(-0.006 8 0.983 9/X)with the hyperbola.The model could meet production needs. |
| Keywords: | Hylobitelus xiaoi population density correlation |
