ABSTRACT The effect of seven constant temperatures (15, 20, 25, 27.5, 30, 32.5, and 35 ± 1°C) on developmental time of Tetranychus urticae Koch on cucumber leaf discs was determined under laboratory conditions of 60 ± 5% RH and a photoperiod of 16 L:8D. The egg-to-adult developmental time decreased significantly with increasing temperature, except at 35°C. To describe the developmental rate of T. urticae as a function of temperature, one linear, and nine nonlinear models (Logan-6 & 10, Lactin-1& 2, Briere-1& 2, Analytis-3, Polynomial, and Equation-16) were fitted to data. By means of the linear model, the lower temperature threshold (T 0) and thermal constant (K) were estimated for the entire immature development of female mites as 7.11°C and 227.27 ± 9.72 DD, respectively. Based on Akaike Information Criterion (AIC) and R 2 adj, Logan-10, Lactin-1, Analytis-3, Logan-10, Analytis-3 were found to be the best models to describe the temperature-dependent development rate of eggs, larvae, protonymphs, and deutonymphs, as well as of total immature development from egg to adult. The results may serve as input for the development of a simulation model that can be used to predict the population dynamics of T. urticae inhabiting cucumber crops.

温度对以黄瓜叶为食的叶螨科（Acari：Tetranychidae）发育的影响

摘要 在 60 ± 5% RH 的实验室条件下，确定了七个恒定温度（15、20、25、27.5、30、32.5 和 35±1°C）对叶螨科赫在黄瓜叶盘上发育时间的影响。光周期为 16 L:8D。除了在 35°C 时，鸡蛋到成虫的发育时间随着温度的升高而显着缩短。将荨麻疹的发育速率描述为温度的函数、一个线性模型和九个非线性模型（Logan-6 & 10、Lactin-1&2、Briere-1&2、Analytis-3、多项式和方程 16）被拟合到数据。通过线性模型，估计雌螨整个未成熟发育的下限温度阈值（T 0 ）和热常数（K）分别为 7.11°C 和 227.27 ± 9.72 DD。基于 Akaike 信息准则 (AIC) 和 R 2 adj，Logan-10、Lactin-1、Analytis-3、Logan-10、Analytis-3 被发现是描述卵、幼虫、原若虫和半成虫的温度依赖性发育速率以及完全未成熟的发育速率的最佳模型从卵发育到成虫。结果可作为开发模拟模型的输入，该模型可用于预测栖息在黄瓜作物上的荨麻疹的种群动态。
