Development time, reproduction, survival and sex ratio were determined for the omnivorous mite Amblyseius swirskii at nine constant temperatures (13, 15, 18, 20, 25, 30, 32, 34 and 36°C) on pepper leaf disks with cattail, Typha latifolia, pollen for food. These data were used to derive life table parameters at these constant temperatures. No development was observed at 13°C. The lower development threshold, based on the fit to the linear portion of the development curve, was 11.3°C. The upper development threshold was 37.4 ± 1.12°C, and the optimum temperature was calculated to be 31.5°C. Average lifetime fecundity ranged from a low of 1.3 ± 0.24 eggs/female at 15°C to a high of 16.1 ± 0.34 eggs/female at 25°C, and r (m) was greatest at 32°C. Non-linear regression of the relationship between temperature and r (m) produced an estimate of 15.49 ± 0.905°C for the lower threshold for population growth and 36.99 ± 0.816°C for the upper threshold for population growth, and an optimum temperature of 30.1°C. These values suggest that A. swiskii populations should grow quickly in response to food availability (pollen or prey) between 20 and 32°C, but that, especially below 20°C, population growth could be slow and impacts on prey populations should be monitored carefully.
在以香蒲（Typha latifolia）花粉为食的辣椒叶片圆盘上，于九种恒温（13、15、18、20、25、30、32、34 和 36°C）下测定了杂食性螨斯氏钝绥螨（Amblyseius swirskii）的发育时间、繁殖、存活和性别比例。这些数据用于在这些恒温下得出生命表参数。在 13°C 时未观察到发育。基于对发育曲线线性部分的拟合，较低的发育阈值为 11.3°C。较高的发育阈值为 37.4±1.12°C，最佳温度计算为 31.5°C。平均一生的总产卵量范围从 15°C 时的低 1.3±0.24 个卵/雌到 25°C 时的高 16.1±0.34 个卵/雌，r（m）在 32°C 时最大。温度与 r（m）之间关系的非线性回归得出种群增长下限的估计值为 15.49±0.905°C，种群增长上限的估计值为 36.99±0.816°C，最佳温度为 30.1°C。这些值表明，A. swiskii 种群在 20 到 32°C 之间，随着食物（花粉或猎物）的可用性而快速增长，但特别是在 20°C 以下，种群增长可能缓慢，应仔细监测对猎物种群的影响。
