摘　　要：为了研究斯氏小盲绥螨[Typhlodromips swirskii(Athias-Henriot)]取食3种不同花粉和椭圆食粉螨[Aleuroglyphus ovatus(Troupeau)]的发育和繁殖,为斯氏小盲绥螨人工大量饲养提供理论依据,在光照L∥D=10h∥14h、相对湿度85%,温度(25±1)℃的条件下,研究斯氏小盲绥螨取食向日葵花粉、丝瓜花粉、玉米花粉和椭圆食粉螨的生物学特性,并组建其实验种群生命表。结果表明,斯氏小盲绥螨取食向日葵花粉、丝瓜花粉、玉米花粉和椭圆食粉螨均能从卵发育至成螨并繁殖后代,雌螨发育历期分别为10.42、8.32、9.18、14.43d;平均每雌总产卵量分别为31.20、65.30、40.17、9.62粒;内禀增长率分别为0.134 3、0.150 2、0.144 9、0.089 5;取食丝瓜花粉的净增殖率(R0=45.057 0)、内禀增长率(rm=0.150 2)和周限增长率(λ=1.162 0)都最大;取食玉米花粉的雌雄性比最大(2.27∶1);取食椭圆食粉螨的雌雄性比(0.91∶1)、净增殖率(4.578 8)和内禀增长率(0.089 5)都最小。Developmental duration, survival rate, fecundity, hatching rate and longevity of Typhlodromips swir- skii （Athias-Henriot） feeding on different pollens and Aleuroglyphus ovatus （Troupeau） were investigated in this study. The life table of laboratory population were constructed at constant temperature of （25 ±1）℃, a photoperi- od of 10L： 14D and relative humidity of 85%. The results indicated that T. swirskii could develop from egg to adult and reproduce when feeding on sunflower pollen, loofah pollen, corn pollen and A. ovatus. The Develop- mental period was 10.42 d, 8.32 d, 9.18 d, 14.43 d, average fecundity per female was 31.20, 65.30, 40.17, 9.62 eggs, respectively; The intrinsic rate of natural increase were 0. 134 3, 0. 150 2, 0. 144 9, 0.089 5. The in- trinsic rate of natural increase, net reproductive rate and the finite rate of increase reached maximum values on loofah pollen： rm ~0. 150 2, R0=45.057 0, ）,~1. 162 0. When mites feed on corn pollen, the sex ratio reached maximum value by 2.27： 1; The intrinsic rate of natural increase （rm =0. 089 5）, net reproductive rate （R0 4. 578 8） and sex ratio （0.91： 1） reached minimum values when predatory mites prey A. ovatus.
