Abstract
AbstractThe life cycle characteristics of Tribolium castaneum for body weight, RNA Concentration, soluble protein concentration and the rates of four dehydrogenases were examined using an outbred wild type stock. Average egg weight decreased until hatching occurred. Larval growth showed an exponential pattern over time reaching a maximum body size just prior to pupation (14 days). Adults increased in size only slightly.Maximum RNA and soluble protein concentrations were observed at 9 and 14 days, respectively, and decreased rapidly thereafter. Activities of glucose‐6‐phosphate, 6‐phosphogluconate, lactate and NADP‐linked isocitrate dehydrogenases also were maximal at 14 days, the time of most rapid growth rate. The data suggest a definite relational pattern between growth rate, RNA and protein synthesis at least during larval development.
