摘要：

以盆栽茄苗上桃蚜为研究对象，用单体和群体饲养的方法研究了85.5mg/m3、199.5mg/m3、399.0 mg/m3和570.0 mg/m34个SO2浓度处理和1个未处理（ck）对桃蚜个体及种群生长发育的影响。研究结果表明，SO2能缩短桃蚜的龄期，降低桃蚜的死亡率，对桃蚜的繁殖有一定促进作用，有利于桃蚜种群动态发展，且199.5mg/m3浓度的SO2处理对桃蚜生长的促进作用明显高于其它浓度。

Abstract:

The effects of sulfur dioxide（85.5 mg/m3、199.5mg/m3、399.0 mg/m3and 570.0 mg/m3 ）and an untreated （ck） stress on the growth and development of individuals and populations of Myzus persicae(sulzer) with individual and group feeding method.The results show that: instar of Myzus persicae(sulzer) was decreased, the mortality of Myzus persicae(sulzer) was decreased,sulfur dioxide had a promotion to the reproduction of Myzus persicae(sulzer), the effects of sulfur dioxide on the population dynamic of Myzus persicae(sulzer),it is propitious to the development of population dynamics of Myzus persicae(sulzer), and 199.5mg/m3 concentrations of sulfur dioxide treatment had a promotion to the growth of Myzus persicae(sulzer) was significantly higher than other concentrations.
