Abstract: Spatial dynamics of 3 wheat aphid populations are investigated.The aggregation and dispersion indices of 3 wheat aphids and their mixed populations are compared under the sameenvironment at different time.It is found that the distribution of wheat aphid populationand its colonization within population show a tendency of periodical aggregation and dispersion with time sequence.It is the first time in the paper to describe this tendency withresistant free vibration model,which is more suitable than Fourier Series.
