摘　　要：1993～ 1 995年连续 3 a对桃蚜在 7种主要寄主植物——桃树、烟草、油菜、杏树、甘蓝、白菜和萝卜上不同时期 4种体色生物型 (红色型、绿色型、黄绿色型和褐色型 )种群消长动态进行了系统调查 ,并对优势生物型的优势度与优势集中性时间变化格局作了剖析。The population dynamics of body colour(red,green,yellow green,brown) biotypes of the green peach aphid ,Myzus persicae (Sulzer) were systematically investigated on 7 species of main host plants including peach (pruns persicae (L.)),tobacco(Nicotiana tabacum L.),rape(Brassica compestris L.),apricot(Prunus armeniaca L.), wild cabbage(Brassica olerocea var. capitata L.),Chinese cabbage(Brassica pekinsneis Rupr.)and radish(Raphanus sativus L.) in various seasons of 1993～1995.The time patterns of dominant degrees and dominant concentralization of the dominant biotypes were analysed. These investigations and analyses are of significant importance to clarify the formation mechanisms of body colour biotypes of the green peach aphid.
