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.

During studies at Ottawa on the physioloLgy of the onion maggot, Hylemya antigua (Meig.), 29 per cent of 2,320 puparia that had been collected in muck soil at Ste. Clothilde, Que., in the autumn of 1957 were parasitized by the braconid Aphaereta pallipes (Say)2. There are few reports of this insect's parasitizing Diptera in Canada and none on its life-history orbehaviour. Hammond (1932) found it in first-generation puparia of the onion maggot at Ottawa. Wishart (1957) reared it from puparia of the cabbage maggot, Hylewyn brassicae (Bouché), collected from St. Martin and St. Rose, Que. Notes on the biologies of two other species of Aphaereta have been published by Graham-Smith (1919) and Evans (1933), the former on Aphaereta cephalotes (Hal.) and the latter on Aphaereta minuta Nees. Both species are parasites of carrion-infesting Diptera.

History Of

The onion maggot, Hylemya antiqua (Meig), has three distinct generations a year in Canada (Armstrong 1924, Hammond 1924, Baker 1928, Lafrance and Perron 1959), and usually two generations in England (Miles 1955). In Canada the three generations overlap considerably and adults of each generation are observed in flight in late summer (Perron et al. 1953). It is the most important pest of onions (Matthewman et al. 1950, Hudon and Perron 1956), and the first generation is the most injurious to the onion plants (Kendall 1932, Miles 1953).

AbstractA gelatine-based diet for rearing the onion maggot, Hylemya antiqua (Meigen), that contains sucrose, evaporated milk, yeast hydrolysate, wheat embryo, cellulose powder, n-propyl disulfide, water, and antibiotics is described. Three consecutive generations reared on this medium were equal in puparial weights, percentages of pupation, adult emergence, and egg hatch, to those reared on onion bulbs. The procedure is simple and two man-hours per week is sufficient for producing 1000 maggots daily.

History Of

In investigations on the life-history of the onion maggot at St. Jean, Que., in 1951, a few specimens of a dipterous predator were found in the rearing cages in the laboratory. They were feeding voraciously on the adults, destroying a colony of nearly 300 flies within two weeks.Specimens were identified by Mr. A. R. Brooks, Systematic Entomology, Division of Entomology, Saskatoon, Sask., as Coenosia tigrina (F.). Mr. G. E. Shewell, Systematic Entomology, Division of Entomology, Ottawa, has stated that nothing is known in Canada about the life-history of this species, but that it is apparently well known as a predator in Europe and that B. M. Hobby has published a long list of species on which it preys, including many anthomyiids.

Aseptic Conditions

Larvae of the onion maggot, Hylemya antiqua (Mg.), were reared individually under aseptic conditions on chemically defined diets. Of 11 growth factors tested, biotin, pantothenic acid, choline, folic acid, pyridoxine, riboflavin, niacin, and thiamine were essential for normal growth and development of the larvae. Omitting one of vitamin B12, thioctic acid, or coenzyme A slowed larval development slightly; fewer larvae pupated, and the ratio of male to female flies was high. However, these growth factors were not essential under the experimental conditions. This is believed to be the first chemically defined diet that will support the growth and development of a phytophagous insect under aseptic conditions. The check diet, which contained all of the vitamins tested, consisted of 19 l-amino acids, 9 B vitamins, coenzyme A, thioctic acid, inosine, thymine, ribonucleic acid, glucose, cholesterol, a salt mixture, and agar.

A Current

Attempts to maintain large cultures of the onion maggot, Hylemya antiqua (Mg.), have led to the development of special glass cages (Perron et al., 1953). Under oar laboratory conditions the lights used to obtain the degree of illumination necessary for acceptable oviposition rates raised the temperature and lowered the humidity excessively within the cage. Reasonable control of these factors was obtained by atomizing cold water into a current of air blown through the cage.
