Summary
Isolated larvae of the parasitic wasp,Pteromalus puparum, were reared in a hanging drop on the haemolymph of diapausing pupae of their natural host,Pieris brassicae. A high mortality was observed, but, in a few cases, the complete development was obtained. The weight of the larvae was evalued according to their calculated volume, and their growth curves were compared to that of normally fed larvae. Among the artificially reared larvae, various types of development were observed and most of them appeared to enter into diapause. The high mortality and the variability of larval growth may be attributed either to the poor quality of the food, or to the bad physical conditions offered to the larvae.
