INTERACTION BETWEEN AMINO ACIDS AND GLUCOSE IN LARVAL NUTRITION OF THE FLY AGRIA HOUSEI (DIPTERA: SARCOPHAGIDAE) AT LOW TEMPERATURE

Abstract

AbstractDifferences were shown in the rate of larval development of the fly Agria housei Shewell reared axenically at 15° and 30°C on chemically defined (meridic) diets with varied proportions of glucose and an amino acid mixture. Although the rate of larval development differed with amino acid level and rearing temperature, the important finding was an interaction between glucose and suboptimal low levels of amino acids that occurred in suboptimal low (15°C) temperature. This shows that nutritional requirements can change with temperature and is noteworthy because any relationship between the nutrition of an organism and environmental temperature can have ecological significance.
