Organisms are said to be in developmental rate isomorphy when the pro- portions of developmental stage durations are unaffected by temperature. Comprehensive stage-specific developmental data were generated on the cabbage beetle, Colaphellus bowringi Baly (Coleoptera: Chrysomelidae), at eight temperatures ranging from 16℃ to 30℃ (in 2℃ increments) and five analytical methods were used to test the rate isomor- phy hypothesis, including: (i) direct comparison of lower developmental thresholds with standard errors based on the traditional linear equation describing developmental rate as the linear function of temperature; (ii) analysis of covariance to compare the lower devel- opmental thresholds of different stages based on the Ikemoto-Takai linear equation; (iii) testing the significance of the slope item in the regression line of arcsin(√p) versus tem- perature, where p is the ratio of the developmental duration of a particular developmental stage to the entire pre-imaginal developmental duration for one insect or mite species; (iv) analysis of variance to test for significant differences between the ratios of developmental stage durations to that ofpre-imaginal development; and (v) checking whether there is an element less than a given level of significance in the p-value matrix of rotating regres- sion line. The results revealed no significant difference among the lower developmental thresholds or among the aforementioned ratios, and thus convincingly confirmed the rate isomorphy hypothesis. 展开更多
