The hypogeal insect pests of eucalyptus are a group of special insect pests, having made serious damages to the young plantation. To solve the problem, it is necessary to use chemicals to control the population of those insect pests. The selection of chemicals and the methods of chemical application must be appropriate so as to lighten and minimize the negative impacts of chemicals on the ecological environment.

桉树地下害虫是一类特殊的害虫群体，在造林初期的危害比较严重，此时应针对不同的害虫选用不同的化学药剂来控制其种群密度，施药时要考虑减轻化学药剂对生态环境的不利影响，应采用毒饵诱杀、根部施药等方式。

Based on the real observation data, forecast equitation or forecast model, the dynamics method such as divergence and vorticity calculation, real data correction, ascending and subsidence calculation was used to simulate the 4D field of divergence, vorticity and vertical velocity at different time, different range and different levels. The field was connected to 3D fields of insect trajectories, yielding the flying speed, direction, ascending area and subsidence. Thus the peak of immigratory insect could be timely monitored. A system of the peak of immigratory insect forecast was set up.
