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.

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.

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.

AbstractThe cabbage maggot, Hylemya brassicae (Bouché), had three generations per year from 1970 to 1973 inclusive, a partial fourth was noted in most years. A small proportion of first generation pupae entered aestivation in 1971.Thermal units required for fly emergence from overwintered pupae fell within a narrow range (174 to 199), but there was little correlation between thermal units and fly emergence in subsequent generations. Lack of adequate moisture delayed establishment of larvae in roots in some generations. Lack of adequate soil moisture delayed establishment of larvae in roots in some generations, and this appeared to be the chief reason for the lack of correlation between thermal units and fly peaks.Throughout this investigation the over-all population remained remarkably constant. Parasitism by a staphylinid, Aleochara bilineata Gyll., and a fungus, Strongwellsea castrans Batko and Weiser, and soil moisture were the most important biological and climatic factors affecting survival. Parasitism of the adult by a nematode, Heterotylenchus sp., was recorded for the first time.Although large numbers of seed maggot adults, Hylemya florilega (Zett.) and H. platura (Meig.), were recorded, few infested rutabaga. Other species trapped included Euxesta notata (Weid.) and Muscina spp.

In a 4-yr study (1974–1977), combinations of selected soil-incorporated insecticides (carbofuran, chlorfenvinphos, disulfoton, fensulfothion, terbufos and isofenphos) and foliar-applied insecticides (Dipel®, methomyl, ethiofencarb/Thuricide®, methamidophos and permethrin) were studied to determine their effects on occurrence of cabbage maggot (Hylemya brassicae [Bouché]) and its parasites, and of various leaf-feeding lepidopterous larvae and aphids during bed-system production of broccoli (Brassica oleracea var. italica Plenck), Brussels sprouts (Brassica oleracea var. gemmifera Zenker), cabbage (Brassica oleracea var. capitata L.) and cauliflower (Brassica oleracea var. botrytis L.). Several soil-incorporated insecticides reduced the numbers of emergent seedlings. Plants treated with carbofuran and chlorfenvinphos had least maggot damage in their roots. Disulfoton was ineffective. The best aphicide was ethiofencarb closely followed by methamidophos. Permethrin was ineffective as an aphicide but very effective against lepidopterous larvae. Numbers of overwintering puparia of H. brassicae were greatest from untreated plants and least from plants treated with chlorfenvinphos. Percentage parasitism by the staphylinid beetle Aleochara bilineata Gyll. averaged 32% in puparia from untreated plots, but only 5.5% in those from treated plots.

The rove beetle, Aleochara bilineata Gyll., is known as a predator and a parasite of the cabbage maggot, Hylemya brassicae (Bouché), in most areas where the latter is an economic pest of cruciferous crops (Wishart, 1957; Wishart et al., 1956, 1957; Hughes, 1959). However, although A. bilineata is an extremely prolific insect (Colhoun, 1953; Wishart et al., 1956), in that the adult beetles destroy root maggot eggs and larvae and the parasite larvae destroy root magpt pupae, little has been reported concerning the economic value of the predator-parasite as a natural control agent. Preliminary studies in Prince Edward Island indicated that the predator destroved large numbers of root maggots but it did not appear to sive economic control (Read, 1960). Details of the biology of this predator have been presented by Colhoun (1953). This is a report of studies conducted to determine the potential value of A. bilineata as a natural control agent, and includes observations on the comparative life histories of host and parasite and notes on predation and parasitism in the greenhouse and on parasitism in the field.

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.

Immatures of the Phelypera schuppeli (Boheman, 1834) (Curculionidae; Hyperinae; Cepurini) are described, illustrated and compared with available descriptions of larvae and pupae of Hyperini. Immatures and adults from midwest (Dourados, Mato Grosso do Sul; Pirenópolis, Goiás) and southeast Brazil (Bauru, São Paulo) were found on leaves of the host plant, Pachira aquatica Aubl. ( Malvaceae, formerly Bombacaceae), a tree used as an ornamental plant in many Brazilian frost-free cities. Larvae of P. schuppeli are exophytic, brightly colored, eruciform and possess abdominal ambulatory ampullae, resembling larvae of Lepidoptera. Mature larvae can spin globular lattice-like cocoons where pupation takes place. Data in the field and under laboratory conditions confirmed previously published biological observations on P. schuppeli. Additional information about defensive behaviors, process of cocoon construction and natural enemies, such as the larval predator Supputius cinticeps (Stål, 1860) (Hemiptera: Pentatomidae) and the prepupal and pupal parasitoid Jaliscoa nudipennis Bouček, 1993 (Hymenoptera: Pteromalidae), are reported.

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.
