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).

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.

Experiments conducted in the greenhouse and in the field by Perron et al. (1958) on 44 varieties of Allium revealed that the varieties Nebuka and Hishiko of A. fistulosum (L.) were significantly more resistant to attacks by the onion maggot, Hylemya antiqua (Meig.), than varieties of A. cepa (L.). This is a report of experiments conducted in 1957 and 1958 in the greenhouse and in the field on the attractiveness of seven of these varieties to oviposition by H. antiqua.

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.

Host Diet

Agria [= Pseudosarcophaga] affinis (Fall.) and Aphaereta pallipes (Say) make an excellent host-parasitoid couple for a determination of effects of host diet on a parasitoid. The anatomy, life history, and behaviour of these insects have been described (Salkeld, 1959; Coppel et al., 1959). Moreover, A. affinis can be reared axenically on chemically defined diets and it is readily attacked in the laboratory by A. pallipes, a parasitoid of the onion maggot, Hylemya antiqua (Meig.). This parasitoid deposits eggs into the body cavity of its host and these increase in size: the duration of the egg stage depends on the age of the host larva when parasitized (Salkeld, 1959).

This is a report on field observations and experiments on the life-history of the onion maggot, Hylemya antiqua (Meig.), conducted from 1955 to 1958 in sandy and organic soils of southwestern Quebec. The dates of emergence of adults, the number of generations, the percentage of pupae entering diapause in each generation, and the relationship between diapause, air temperature, and precipitation were recorded.

AbstractDirect contact toxicity data were obtained with selected insecticides on 24–48 h old adults of insecticide-susceptible onion maggot, Hylemya antiqua (Meigen), cabbage maggot, H. brassicae (Bouché), and seedcorn maggot, H. platura (Meigen); and on third-stage darksided cutworm, Euxoa messoria (Harris). All insecticides were highly toxic to onion maggot flies, with the order of toxicity being: cypermethrin > chlorpyrifos > fenvalerate > permethrin > parathion > isofenphos > terbufos. Chlorfenvinphos was 1.4 × more toxic to cabbage maggot adults than parathion; the pyrethroids were less toxic, with fenvalerate being 1/13 as toxic as parathion. The order of toxicity of insecticides tested on seedcorn maggot flies was: diazinon > cypermethrin > chlorpyrifos > fenvalerate > permethrin. With the darksided cutworm, DDT and leptophos were 1/10 and 3/4 as toxic as chlorpyrifos, while cypermethrin, fenvalerate, permethrin, and decamethrin were ca. 10, 11, 12, and 120 × more toxic, respectively.

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.
