摘　　要：研究了奥氏钝绥螨杀扑磷抗性种群在20℃、25℃与30℃温度下的繁殖适合度.结果表明,在20～30℃温度范围培养下,随着温度的升高,奥氏钝绥螨杀扑磷抗性种群的各发育历期缩短,雌性比降低,每雌日产卵量升高,但在25℃温度下每雌总产卵量均明显高于在20℃与30℃的每雌总产卵量.25℃温度是室内人工繁育奥氏钝绥螨杀扑磷抗性种群的最适温度.The reproduction fitness Schicha （Acari ： Phytoseiidae） were temperature from 20 ℃ to 30℃, of methidathion resistance predacious mites A rablyseius womersleyi studied at 20℃, 25℃and 30 ℃, respectively. With the raise of the all developmental stages of A. womersleyi become shorter and it decreased, the ratio of female and improved the fecundity of a female in one day. The total eggs laid by a female in a generation was the highest at 25 ℃. The results indicate that 25 ℃ is the most suitable temperature for the artificial culture of the methidathion resistance predacious mites A. womersleyi.
