温度对昆虫发育速率的影响通常采用线性模型和Logan模型。线性模型常用于估计发育下限。然而，它不能用来计算上发展阈值。此外，它无法描述在最佳发育温度附近、温度下和温度以上的发育速率。Logan模型可以反映温度依赖的发育速率从低到高的发育阈值。它通常用于计算最佳发育温度和发育上限，但不用于计算发育下限。为了避免这两种模型的缺点，我们在温度升高对酶活性和变性影响的基础上建立了一个新的模型，即“性能模型”。绩效模型最早由休伊和史蒂文森（美国）使用。Zool. 19, 357-366)提供了体温对表现影响的统计描述，但他们没有提供潜在的生理机制。很少有研究使用性能模型来分析昆虫的温度依赖性发育速率，可能是因为缺乏理论依据。本文为该模型的应用提供了理论依据，并利用性能模型对两种昆虫的发育速率数据进行了评价。我们发现绩效模型比线性模型和Logan模型更有优势，并且该模型可以同时获得下、上发展阈值。(C)韩国应用昆虫学会、台湾昆虫学会、马来西亚植物保护学会，2010。Elsevier B.V.版权所有。
The linear and Logan models are usually used to describe the effect of temperature on insect developmental rate. The linear model is often used to estimate the lower developmental threshold. However, it cannot be used to calculate the upper developmental threshold. Additionally, it fails to describe developmental rates near, at, and above the optimal developmental temperature. The Logan model can reflect temperature-dependent developmental rates from the lower to upper developmental thresholds. It is often used to compute the optimal developmental temperature and the upper developmental threshold, but it is not used to compute the lower developmental threshold. To avoid the disadvantages of these two models, we develop a new model, the 'performance model' on the basis of the impact of increasing temperature on enzyme activity and denaturation. The performance model was first used by Huey and Stevenson (Amer. Zool. 19, 357-366) to provide a statistical description of the impact of body temperature on performance, but they did not provide underlying physiological mechanisms. Few studies have used the performance model to analyze the temperature-dependent developmental rates of insects, perhaps because of the lack of a theoretical justification. Here, we provide a theoretical justification to use the model and we use the performance model to evaluate the developmental rate data of two insect species. We found that the performance model has advantages over the linear and Logan models, and that the lower and upper developmental thresholds can be simultaneously obtained from this model.
