It was hypothesized that the development rate lines of ectotherms within a taxon such as a family would have a common intersection. Thus for a given temperature, the development time should be the same for all the species within any specified taxon. In the current study, the data on temperature-dependent development rates of species of the Aphididae and Tetranychidae families were used to test the validity of the common-intersection hypothesis. The hypothesis was supported with either dataset used. In addition, the current study tested the common-intersection hypothesis through mathematical analysis on the basis of two linear relationships (i.e., the linear relationship between temperature and development rate and that between the lower developmental threshold and the sum of effective temperatures). An attempt was made to combine the rate isomorphy hypothesis that all the lower developmental thresholds of different stages were assumed to be equal for a single species with the common-intersection hypothesis for related species within a taxon and hypothesize that if these two hypotheses hold, then for any developmental stages a common temperature of all stages should exist. specialized Effective temperature Linear model Aphididae Tetranychidae 080 020 36 7 422-429 2011 0306-4565 https://www.documentation.ird.fr/hor/fdi:010054102 10.1016/j.jtherbio.2011.07.009 0306-4565 [F B010054102] https://www.documentation.ird.fr/hor/fdi:010054102 https://www.documentation.ird.fr/intranet/publi/2011/11/010054102.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2011-11-30 2017-08-23 fdi:010054102 fre
