| Abstract: | A practical and easy using method of forecasting outbreak of Matsucoccus matsumurae was put forward in this paper. With systematic observation of outbreak time of this insect in five years, expected distance values and mean standard errors of different instars were calculated. Meanwhile, a linear regressive equation was established and used in insect control practice. |
