Trehalose of Culex pipiens fatigans.

Trehalose was found to occur in the mosquito, Culex pipiens fatigans, to the extent of 23 to 49% of total free sugars in different developmental stages of the insect. Induction of stress to the insects led to significant reduction in the trehalose of larvae and glucose of adults. The label from alpha,alpha'-U-14C-trehalose readily incorporated into lipids of the adults in which triglycerides seemed to undergo rapid turnover.
