From 1974 to 1978, we released 14 species of European parasites (ca. 82,000 insects from 3 agromyzid host species on alfalfa) as part of a biological control effort against the alfalfa blotch leafminer, Agromyza frontella (Rondani), in the USA. A list of release locations, dates, and parasite numbers is presented. Techniques for rearing 4 of the species are briefly described. Two species, Dacnusa dryas (Nixon) (Hymenoptera: Braconidae) and Chrysocharis punctifacies Delucchi (Hymenoptera: Eulophidae), have been established in Delaware. Sufficiently large field populations of these species were present in 1978 so that insects were collected by sweeping and moved to other release locations.
