A morphometric comparison of aphid mummies containing diapausing vs. non-diapausing larvae of <i>Aphidius rhopalosiphi</i> (Hymenoptera: Braconidae, Aphidiinae)

Abstract

Abstract The morphology and ultrastructure of aphid mummies formed by diapausing 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 thecocoon weight were observed depending on parasitoid development. A morphometric characterization of the two groups of mummies is given.
