INSECTS can maintain their blood trehalose at levels which are characteristic of the species and stage of development1. In the silkworm, Bombyx mori, the blood trehalose-level returns rapidly to normal after being experimentally altered2. In saturniid silkmoth pupæ, superficial injury is followed by accelerated carbohydrate turnover and net conversion of glycogen to trehalose, which afterwards returns to its normal level3. We have now discovered characteristics of the enzymes of trehalose and glycogen synthesis in silkmoths which may help to explain these regulatory phenomena.
