| Abstract: | The spatial pattern and the vertical and level distribution of the Liriomyza sativae Blanchard in cotton field were studied with the indices of patchness,The result showed that the spatial pattern of Liriomyza sativae Blanchard belong to random distribution,and the number of the Liriomyza sativae Blanchard in the lower part was more than middle part,and the middle part was more than the upper part.It also showed the harm rate of Liriomyza staivae to cotton is almost the same the margin and middle part of the cotton field. |
