Among them multi-types of body colour and special types of hosts are the most universal phenomena. In our experiment, methods of microsatellite primer PCR molecular marker and partial gene sequence analysis of mitochondrial DNA COⅠ-Ⅱwere used to analyze genetic diversity of two body colour bio-types (red bio-type and green bio-type) of green peach aphid from different plants and relationship between green peach aphid and host plants by separately selecting individuals of aphid from rape, Chinese cabbage and tobacco. The main results as follows: 1. Selecting An Ruisheng'method of extracting DNA from small sized insect, using this method can extract DNA well and steadily.
