Winter polyol metabolism of the house spider, Parasteatoda tepidariorum is essentially the same between adults and nymphs

Abstract

Low-molecular-weight carbohydrates accumulated in the overwintering adults of Parasteatoda tepidariorum were identified. At least three compounds, sorbitol, scyllo-inositol, and myo-inositol, were detected in the extract. The spectrum and the amounts of accumulated polyols were almost the same as those accumulated in the overwintering nymphs. Thus, within the same species, winter polyol metabolism did not differ between the developmental stages.
