The common green lacewing Chrysoperla carnea (Steph.) (Neuroptera: Chrysopidae) is a polyphagous and efficient predatory species commonly found in a wide range of agricultural habitats. It plays an important role in biological control of pests. The effect of temperature on developmental rate of the predator C. carnea was studied at 7 constant temperatures, 15, 20, 25, 27, 30, 32, and 35 °C, 50 ± 10% RH, and a photoperiod of 16:8 h (L:D). Six nonlinear models were evaluated to determine the trend of developmental rate of the predator in examined temperatures and to estimate thermal thresholds of development. Nonlinear models were evaluated based on coefficient of determination (R2), adjusted coefficient of determination (R2adj), residual sum of squares (RSS), and Akaike information criterion (AIC), beside biological significance of the estimated values for the model parameters. Among evaluated nonlinear models, Lactin-2 for all immature stages was the best-fitted model on observations, considering statistical criteria and biological significance of the estimations. The values of the lower temperature threshold by using Lacin-2 were 9.90, 10.90, 11.90, 11.40, 11.11, 11.61, and 11.30 °C for incubation period, 1st, 2nd, and 3rd larval instars, overall larval period, and pupal and total immature stages, respectively. The values of the upper temperature threshold for the mentioned developmental stages were 33.82, 37.66, 33.14, 34.04, 33.58, 32.14, and 32.18 °C, respectively. Estimated values for the optimal temperature for incubation period, 1st, 2nd, and 3rd larval instars, overall larval period, and pupal and total immature stages were 30.69, 30.22, 30.90, 30.34, 30.90, 31.75, and 31.72 °C, respectively. The results, in addition to determine thermal tolerance for the development of C. carnea, provided advantage information for better use of C. carnea in biological control programs.

温度对常见绿色草lace（Chrysoperla carnea，Steph。）的发育速度的影响的建模（神经翅目：Chrysopidae）

常见的绿色草laceChrysoperla carnea（Steph。）（Neuroptera：Chrysopidae）是一种多食性和有效的掠食性物种，通常在广泛的农业栖息地中发现。它在害虫的生物防治中起着重要作用。在7个恒定温度，15、20、25、27、30、32和35°C，50±10％RH和光周期为16：8的恒定温度下研究了温度对捕食者角膜梭菌发育速率的影响h（L：D）。对六个非线性模型进行了评估，以确定在检查温度下捕食者的发育速率趋势，并估计发育的热阈值。根据确定系数（R2），调整后的确定系数（R2adj），残差平方和（RSS）和Akaike信息准则（AIC）对非线性模型进行评估，除了具有生物学意义的模型参数估计值。在评估的非线性模型中，考虑到统计标准和估计的生物学意义，所有未成熟阶段的Lactin-2是最适合观察的模型。使用Lacin-2的较低温度阈值在潜伏期，第1、2和3龄幼虫龄，幼虫总龄，total期和总期分别为9.90、10.90、11.90、11.40、11.11、11.61和11.30°C不成熟的阶段，分别。所述发育阶段的最高温度阈值分别为33.82、37.66、33.14、34.04、33.58、32.14和32.18°C。孵化期，第一龄，第二龄和第三龄幼虫，幼虫总期以及p和总未成熟期的最佳温度的估计值为30.69，30.22、30.90、30.34、30.90、31.75和31.72°C。这些结果，除了确定对角叉菜的发育的热耐受性之外，还为更好地在生物控制程序中使用角叉菜提供了有利的信息。
