| Abstract: | The spatial distribution of pseudococcuski (Kuwana) was determined by using the pro-liferative coefficient (c),the law of Taylor power,the regression of lwao -..The result showed that the spatial distribution of the insect belongs to concentration distribution and the lower the insect's density,the higher the concentration degree.The basic composition of distribution is individual group.The distribution of individual group is random and the aggressive intensity changes with different direction. |
