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.
