| Abstract: | The spacial distribution of wheat aphids (Macrosiphum avenae F,Phopalosiphum padi L,Schizaphis graminum Rond ) and the larva of Aphidius avenae Halida was determined with both Iwao's M-m~*regression method(l968)and Taylor's power law(l96l). The results indicated that the spacial distribution of the aphids and the larva of A.avenae belonged to the aggregation distribution. Based on the distribution, the most moderate sampling number for estimating the population of wheat aphids in the fields was presented and the sequential sampling table was got according to the control index of 5 heads per individual plant. |
