Since a technique for mass rearing of the cabbage maggot Hylemya brassicae (Bouché), was described (Read, 1960), inquiries from different countries indicate that many workers encounter difficulties in rearing this insect in captivity. This paper discusses these difficulties and describes methods successfully used by the authors for establishing and maintaining cultures in the greenhouse. Using these methods, 22 successive generations of H. brassicae have been reared at Belleville in less than four years.

Large numbers of each of the stages of the cabbage maggot, Hylemya brassicae (Bouché), are often required for studies on biology or on biological or chemical control of the insect. A method has been reported by Sherwood and Pond (1954) for maintaining a colony for more than a year. The method described herein enables mass rearing of eggs, larvae and pupae and easy separation of any stage.

AbstractCounts of the cabbage maggot, Hylemya brassicae (Bouché), on cabbage did not conform to the Poisson distribution, there being an excess of uninfested and highly infested plants over the expected number. But when the negative binomial series was fitted to the observed distribution, the discrepancies were not significant when tested by chi-square. The negative binomial parameter k tended to increase with density. Using a common k, the distribution of the various stages may be described by expansion of (q − p)−k, when values of k are as follows: egg 0.78, larva 0.71, pupa 0.84. Three different transformations are offered for stabilizing the variance of field counts.

AbstractThe cabbage maggot, Hylemya brassicae, has a facultative diapause induced by the appropriate conditions of light and temperature: 16 hours of light per 24 hours at 20 °C produce nondiapause pupae while 12 hours of light per 24 hours at 20 °C produce diapause pupae. Diapause can be terminated if the pupae are exposed to temperatures from 0 to 5 °C for 4–5 months. Discrepancies in the literature with regard to the foregoing facts are explained.

AbstractIn Hylemya brassicae (Bouché) little oviposition occurred when access to host plant material was denied. The mustard oil, allyl isothiocyanate (AITC), stimulated the flies into greater activity and attracted them to its source. Sinigrin and four other glucosinolates (mustard oil glucosides) tested induced oviposition. AITC by itself did not induce, oviposition, but in the presence of a glucosinolate, small concentrations of AITC caused an increase in the number of eggs laid. Glucose, sucrose, casein, wheat germ oil, and a mixture of B-vitamins did not influence oviposition at the concentrations tested, but casein hydrolysate inhibited it. The role of glucosinolates and common nutrients in host selection by H. brassicae is discussed.

During investigations on the natural enemies of root maggots attacking Cruciferae, the beetle Baryodma ontarionis Casey was reared from puparia of the cabbage maggot, Hylemya brassicae (Bouché). This was not unexpected, for Gibson and Treherne (1916) had reported a similar occurrence; the staphylinid beetles reared at that time were identified by Casey (1916), who decided that they belonged to the verna group of Baryodma and assigned the name Baryodma ontarionis. Casey (loc. cit.) considered the species rather common and stated that it did not seem to resemble any European species; but Mr. W. J. Brown (in litt.), Systematic Entomology, Division of Entomology, Ottawa, who identified the beetles collected in 1950, is of the opinion that B. ontarionis is synonymous with Aleochara bilineata Gyll., tvhich attaclrs the cabbage maggot in Europe. Wadsworth (1915) dealt with the biology of A. bilineata, giving detailed descriptions of the immature stages. A study of the biology of B. ontarionis was carried out at the Belleville laboratory as part of n program of parasite introduction with the purpose in view of using the information to evaluate the beetle as a factor in the control of root maggots that are severe pests of cabbage, cauliflower, turnip, and radish.

AbstractA study of sampling variation in field populations of the cabbage maggot, Hylemya brassicae (Bouché), on cabbage in Ontario, revealed that inter-plant and block differences were rarely significant. For the immature stages, the most appropriate sample unit was the plant root together with a 4- to 6-in. diameter core of soil. The number of samples required was inversely proportional to population density; this relationship was graphed for three levels of sampling precision.The insect is bivoltine in eastern Ontario but has three generations in the southwestern part of the province.
