Extract

Early in September, 1953, an examination of 370 first-generation pupae of the onion maggot, Hylemya antiqua (Mg.), collected from large field rearing cages at St. Jean, Que., revealed that 41, or 11.1 per cent, were parasitized. The parasite was identified as Spalangia rugosicollis Ashm. Dr. O. Peck, Systematic Entomology Unit, Entomology Division, Ottaiva. Dr. Peck (in litt.) stated that this is the first record of this parasite attacking the onion maggot and thatthe Nearctic species in this genus have been greatly confused.
