我们研究了十个恒温（20.0、22.5、25.0、27.5、30.0、32.5、35.0、37.5、39.0 和 41.0 摄氏度）对云南Liposcelis yunnaniensis Li & Li（Psocoptera：Liposcelididae）发育、生存和繁殖的影响。在 39.0 和 41.0 摄氏度时，没有个体能够成功发育或繁殖。从20℃到37.5℃，从卵到成虫的发育周期为20℃时的64.3天到35℃时的16.1天。卵、若虫和组合未成熟阶段的较低发育阈值分别估计为15.08、15.13和14.77℃。雌虫羽化后经历产卵前期，22.5℃时为18.5d，35℃时为3.11d，20℃时为16.3d。云南Liposcelis yunnaniensis在35℃时产卵最多，22.5℃时产卵最少。35℃饲养种群的内在增长率最高，平均代数较短。时间，以及与其他温度相比最短的群体倍增时间。根据Weibull频率分布，在所有温度下饲养的云南乳杆菌均具有III型存活曲线（c < 1.0）。根据生命表参数估计，我们建议该物种的最佳温度范围是 25 至 37.5 摄氏度。这些数据为我们提供了有关云南 L. yunnaniensis 种群生物学的有用信息，可用于更好地管理该物种。
We investigated the effects of ten constant temperatures (20.0, 22.5, 25.0, 27.5, 30.0, 32.5, 35.0, 37.5, 39.0, and 41.0 degrees C) on the development, survival, and reproduction of the psocid Liposcelis yunnaniensis Li & Li (Psocoptera: Liposcelididae). At 39.0 and 41.0 degrees C, none of individuals could develop successfully or reproduce. From 20 to 37.5 degrees C, the development period from egg to adult ranged from 64.3 d at 20 degrees C to 16.1 d at 35 degrees C. The lower developmental threshold for egg, nymph, and combined immature stages were estimated at 15.08, 15.13, and 14.77 degrees C, respectively. After emergence the females went through a preoviposition period that ranged from 18.5 d at 22.5 degrees C to 3.11 d at 35 degrees C, whereas it was 16.3 d at 20 degrees C. Liposcelis yunnaniensis produced most eggs at 35 degrees C and the fewest at 22.5 degrees C. The population reared at 35 degrees C had the highest intrinsic rate of increase, shorter mean generation time, and shortest population doubling time compared with other temperatures. According to Weibull frequency distribution, L. yunnaniensis reared at all the temperatures had type III survivorship curves (c < 1.0). Based on life-table parameter estimations, we suggest that optimum range of temperatures for this species is from 25 to 37.5 degrees C. These data give us useful information on population biology of L. yunnaniensis and can be used to better manage this species.
