ABSTRACT
In poikilothermic animals the dependence on temperature of physiological processes such as growth, respiration, heart-beat, wing-beat, motility, etc., has been studied, but no information seems to be available for the temperature dependence of the synthesis of a defined product. An opportunity to measure rates of synthesis of specific products, namely, the accumulation of caloric reserves, is offered by the female mosquito. When mosquitoes are starved they catabolize all glycogen and triglycerides; after subsequent feeding on a single, measured meal of sugar, quantitative relations can be established between this precursor and its products, the new glycogen and triglyceride pools (Van Handel, 1965 a). In the present investigation, this biological technique has been used to determine the velocity with which these two products accumulate at different temperatures.
