摘　　要：观察了巴氏钝绥螨Amblyseius barkeri Hughes在5种温度(15、20、25、30和35℃)、食料为芦笋蓟马,相对湿度72%,L∶D=12∶12条件下的发育历期、存活率和繁殖力。结果表明:巴氏钝绥螨卵、幼螨、前若螨、后若螨及世代发育历期在15℃下最长,随着温度的升高而缩短,35℃下最短。产卵前期在15～30℃下,随温度的上升而缩短,35℃下稍有延长。存活率15℃下最低,随温度的上升而提高,30℃下最高。产卵量15℃下最少,其次是35℃,20～30℃下产卵量较多。根据实验结果,组建了巴氏钝绥螨以芦笋蓟马为食料在5种不同温度下的实验种群生命表。The developmental duration, survival rate and fecundity of Amblyseius barkeri Hughes were investigated under five different temperature conditions （ 15,20,25,30,35℃ , RH72% , L： D = 12 ： 12 ） when feeding on Thrips tabaci Lindeman. The results indicate that the developmental duration of eggs, larvae, protonymphs, deutonymphs and an entire generation of A. barkeri shortened with increasing temperature; the longest developmental durations were at 15℃ , and the shortest at 35℃. Duration of the preoviposition stage shortened when temperatures increased from 15℃ to 30℃ , but was prolonged at 35℃. The survival rates of all generations improved when temperatures increased; the lowest being recorded at 15℃ and the highest at 30℃. Oviposition was lowest at 15℃ , then at 30℃ , with temperatures between 20℃ and 30℃ the most suitable for oviposition. Population life tables of A. barkeri feeding on T. tabaci at five different temperatures were constructed based on these results.
