Several populations of the green peach aphid, Myzus persicae (Sulzer), were collected in the most important Italian peach-growing areas. In these populations, collected as primary colonies or as secondary ones, total esterase content and acetylcholinesterase sensitivity towards pirimicarb was assessed using biochemical assays. Most of the individuals analysed generally exhibited an elevated esterase content, and in some cases acetylcholinesterase insensitivity. The implications of resistance levels and distribution on M persicae control strategies are discussed.
在意大利最重要的桃树种植区采集了几个群体的桃蚜(烟蚜,Myzus persicae (Sulzer))。在这些作为原种群或次种群采集的群体中,使用生化测定法评估了总酯酶含量以及乙酰胆碱酯酶对抗蚜威的敏感性。大多数被分析的个体通常表现出酯酶含量升高,在某些情况下还表现出乙酰胆碱酯酶不敏感。文中讨论了抗性水平和分布对桃蚜防治策略的影响。
