Distribution model of organism development times. Academic Article uri icon


  • It is shown in this analysis that the distribution of organism development times for constant and variable temperatures can be described based upon one simple assumption. This assumption is that the concentration of enzymes which are rate controlling for development are symmetrically distributed about some genetically determined mean concentration. It then follows mathematically that the skew in the distribution in development times, observed by Stinner, Butler, Bacheler & Tuttle (1975) and others, results naturally from the transformation from development rates to emergence times. The distribution model is shown to agree with observed data for (i) boll weevil, Anthonomus grandis Boheman, and (ii) cotton fleahopper, Pseudatomoscelis seriatus Reuter, reared under both constant and variable temperature regimes. The resulting model enables predictions of the distribution of emergence times for organisms reared under any set of variable temperature field conditions. 1977.
