Abstract
The morphology and ultrastructure of aphid mummies formed by diapausin g and non-diapausing larvae of Aphidius rhopalosiphi De Stefani Perez, are described. Two types of silk thread were present in both types of cocoons: well-structured rounded threads, and flat threads which form a gum coating. Differences in the cocoon weight were observed dependi ng on parasitoid development. A morphometric characterization of the t wo groups of mummies is given.
