温度与昆虫生长发育关系模型的发展与应用

Development and application of models for describing the effects of temperature on insects' growth and development

昆虫作为变温动物,对温度变化更为敏感。研究温度变化对昆虫生长、发育的影响有重要理论和实践意义。目前已构建了多个描述温度与昆虫增长速率的关系模型,用于解释温度对昆虫发育速率的影响。这些模型大体可分为两类:没有热动力学基础的纯描述性模型和有热动力学基础的应用性模型。本文在对现有的有关温度变化与昆虫生长发育关系的11个模型进行评述的基础上,结合作者近年来的研究,重点介绍了迄今为止国际上最为合理的、用以反映温度对昆虫发育速率影响的Sharpe-Schoolfield-Ikemoto模型,并利用这些模型拟合了一组温发育速率数据用以展示这些模型的应用。

As ectotherms,the growth and development of insects is affected by temperature.Several mathematical models have been built to describe the relationship between temperature and the development rate of insects.These models can be generally divided into two categories;the first are based on thermodynamics whereas the second are not.In this paper,we comment on eleven mathematical models that attempt to describe the temperature-dependent developmental rates of insects and emphasize the advantages of the Sharpe-Schoolfield-Ikemoto（SSI） model with reference to our previous studies.We consider this model to be the best so far developed.We illustrate the application of the various models with a published dataset of developmental rate versus temperature.
