Summary

D. alboannulatus (Ratz) is a frequent parasite ofP. flammea Schiff. andB. piniarius (L.); its mass production in the laboratory was therefore investigated.

The species is not very specialized. It could be bred in the pupae of 10 species of lepidoptera, 4 of which were not yet known from literature. The adult life may be prolonged by low temperatures without loss of viability; a female deposits under favourable conditions about 190 eggs; the development is completed in 18 days at 27,2°C. All these properties facilitate the mass production of the parasite in the laboratory and its possible use for biological control.
