Abstract

In experiments on development of poikilotherms in alternating temperatures, developmental duration frequently has been compared with some expected duration. The expected durations have generally been calculated erroneously from an average of rates determined at constant temperatures. A method is described to predict correctly the expected duration, based on the average of expected developmental durations. The procedure may also be used to predict correct duration for apparent retarding or accelerating of development under the Kaufmann effect, where rate-temperature relationships are curvilinear. The method is particularly useful where developmental durations are relatively short.
