According to the hypothesis of isomorphy rate, all the lower developmental thresholds of different developmental stages of an insect are equal. However, there is lack of a formal statistical method for testing whether there is a significant difference among the lower developmental thresholds on the basis of the traditional linear model describing developmental rate as a linear function of temperature. For comparing the lower developmental thresholds of different developmental stages, a new method based on the Chow test is proposed in the current study. Another feasible way based on the linear model proposed by Ikemoto and Takai is also proposed. The lower developmental thresholds can be compared by the analysis of covariance on this linear model. The current study can be used to test the hypothesis of isomorphy rate. When comparing the lower developmental thresholds of different geographical populations for one insect species, the two methods proposed here are also applicable.
根据同形率假说，昆虫不同发育阶段的所有较低发育阈值是相等的。然而，基于将发育速率描述为温度的线性函数的传统线性模型，缺乏一种正式的统计方法来检验较低发育阈值之间是否存在显著差异。为了比较不同发育阶段的较低发育阈值，本研究提出了一种基于邹检验的新方法。还提出了另一种基于池本和高井提出的线性模型的可行方法。通过对该线性模型进行协方差分析，可以比较较低发育阈值。本研究可用于检验同形率假说。当比较一种昆虫不同地理种群的较低发育阈值时，这里提出的两种方法也适用。
