Application Program

Several Canadian workers have reported various results in the control of the onion maggot, Hylemya antiqua (Meig.), with chemicals applied to the soil surface (Dustan, 1938; Matthewman et al., 1942; McLeod, 1946; Perron et al., 1953; Finlayson and Handford, 1954). In these tests, the date of the first application of insecticide coincided with early oviposition of the insect, the second and third applications following at weekly or ten-day intervals. Satisfactory control was therefore dependent to a great extent on the grower's ability to recognize the beginning of oviposition by the pest in the field. However, many growers find this recognition difficult and poor control often results from the three-application program.

Stimulate Plant Growth

In organic soils of southwestern Quebec from 1955 to 1958, dieldrin heptachlor and endrin wettable powders mixed at the rate of 1 ounce of toxicant per pound of onion seed applied for the control of the onion maggot, Hylemya antiqua (Meig.) were highly effective. The heptachlor treatment appeared to stimulate plant growth. Toxaphene as seed treatment was poor, while di-syston also as seed treatment was effective but reduced germination by one-third. A soil surface treatment with chlordane dust at 4.5 pounds of toxicant per acre gave also a fair control where seed had not been treated. Combinations of dieldrin or DDT seed treatments with chlordane or aldrin soil surface treatments when plants averaged 2 inches high were not more effective than a seed treatment alone.

Experiments at two localities in the interior of British Columbia in 1952 and 1953 showed that a seed treatment of dieldrin at 0.5 oz. per pound of seed gave as good control of the onion maggot as any other treatment, was not phytotoxic, and gave the highest yield of marketable onions each year. Lindane, 25 per cent wettable powder, applied three times at 10-day intervals to the soil surface at 1 lb. of toxicant per acre per application gave consistently good control and high yields, but was more expensive in both labour and materials. Calomel at 1 lb. per pound of seed gave satisfactory control in a light infestation but cost twenty times as much as dieldrin. DDT at 8 oz. per pound of seed gave effective control but the bulk of insecticide on the seed caused jamming of the seeder. When the amount of DDT was reduced the degree of damage increased. Lindane as a seed treatment at 1 oz. per pound of seed was extremely phytotoxic. The same amount of aldrin applied in a similar manner was phytotoxic but to a lesser degree.

Diazinon and V-C-13 granular formulations, applied as furrow treatments at the rate of 1 and 2 pounds toxicant per acre, and diazinon wettable powder as seed treatment at [Formula: see text] ounces toxicant per pound of seed, effectively controlled populations of the onion maggot, Hylemya antiqua (Meigen) resistant to cyclodiene insecticides in southwestern Quebec, in both mineral and organic soils. EN 18133 granular formulation was also very effective but caused a slight delay in germination without, however, affecting the stand or decreasing the yield to any extent. Ethion, Trithion and Guthion granular formulations as furrow treatments at either 1 or 2 pounds toxicant per acre, and also as wettable powder seed treatments at the rate of 1 ounce toxicant per pound of seed, were significantly inferior to Diazinon, V-C-13 and EN 18133. Dylox water soluble powder, applied as a drench post-emergence treatment at 4 pounds toxicant per acre, gave poor control.

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.
