The results showed that the aphids were either restrained or promoted when they fed on different treatment crops, compared with the control not fed by aphids and the corresponding treatment previously fed by different aphid species. S. avenae restrained the growth of S. graminum (MRGR=0.0974±0.0071) on 98-10-30, but S. graminum promoted the growth of S. avenae (MRGR=0.1614±0.0048) on 98-10-30. Penetrations of aphids promoted the growth of S. avenae on Amigo, while promoted growth of S. graminum on Batis.

结果表明：品种不同，蚜虫在不同处理条件下取食作物时受到的影响也不同，即在品种98-10-30上，通过与前期不接虫的对照及前期接不同麦蚜的相关处理比较，麦长管蚜对后期取食的麦二叉蚜(MRGR=0.0974±0.0071)具有抑制作用，而麦二叉蚜对后期取食的麦长管蚜(MRGR=0.1614±0.0048)却有促进作用；在品种Amigo上，前期麦蚜的危害对麦长管蚜的取食具有促进作用，而在品种Batis上前期危害对麦二叉蚜的取食具有促进作用。

In nucleotide and amino acid sequenece levels, this protein was identified as GroEL protem of endosymbiotic bacterium (Buchnera sp.) of aphid.

以玉米蚜杨凌生物型为材料，设计特异性引物采用PCR的方法在国内首先克隆了一种玉米蚜体内参与传毒的共生菌groEL基因，序列测定结果表明：玉米蚜杨凌生物型共生菌groEL基因全长为1647bp。

To further explore the phylogenetic relationships between the aphid Myzus persicae and its endosymbiotic bacterium Buchnera, COⅠ/COⅡ, 12S/16S rRNA and EF-l alpha genes in four populations of M. persicae were amplified. Through phylogenetic trees constructed by the COⅠ/COⅡ, 12S/16S rRNA and EF-l alpha genes in M.
