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.

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.

AbstractAn onion maggot, Hylemya antiqua (Meigen) (Diptera: Anthomyiidae) strain, having low level (≤ × 5) resistance to organophosphorus insecticides, was selected with parathion to determine if higher resistance levels to the selection agent and other insecticides used for onion maggot control would result. Parathion resistance levels increased to ×10.1 and ×23.8 after 4 and 14 generations of selection, respectively; without further selection, resistance levels declined by ca. 1/2 in 6–7 generations. Parathion resistance was ×24.4 after 20 generations of selection and resistance levels to ethion, diazinon, fonofos, and carbofuran were 2 to 3 times higher than those measured initially. The pattern of resistance development in field strains of onion maggot collected in 1975 and 1980 was similar to that observed in the laboratory selection program, but resistance levels were lower, probably because of lower selection pressure and the variety of chemicals used under practical conditions. After 14 generations of parathion selection, resistance levels were ×23.8 and ×10.1 to parathion and carbofuran, respectively. After 12 additional generations of carbofuran selection, carbofuran resistance increased to ×31.2, while the level of parathion resistance remained the same.
