Extract

Most laboratory studies of insect development have been conducted under constant temperature conditions. Since constant temperatures are rarely encountered under natural conditions, results of such studies are limited in their application. It is desirable to compare the effects of fluctuating temperatures and constant temperatures on insect development. For this purpose, control devices which produce regular alternations of periodic constant temperatures or continuously varying temperatures of a predictable nature are needed.
