The ultrastructural and biochemical characteristics were studied in active and diapausing pupae of Cameraria ohridella. The active pupae contained developing internal organs, while those in diapause mostly numerous non-differentiated cells packed with stored nutrients. Triacylglycerols (TGs) were the main lipids stored by pupae and were more abundant in diapausing than active pupae. The amount of diacyglycerols (DGs) and phospholipids (PLs) was almost identical in both groups. The results reveal significant differences between the two summer pupal forms of C. ohridella and further our understanding of the developmental strategy of this successful, invasive pest insect.
