“…Bodnaryk (1992) showed that S. arvensis from Manitoba could serve as a host for the flea beetle, Phyllotreta cruciferae (Chrysomelidae). In caged feeding trials in Manitoba, Lamb and Palaniswamy (1990) found that the striped flea beetle P. striolata (F.) fed on eight crucifers in the genera Brassica, Raphanus and Sinapis and not on the legume Pisum; it also fed less on S. arvensis and S. alba than on plants in the other genera.…”

. An updated review of biological information is provided for Sinapis arvensis L. Native to the Old World, the species is widely introduced and naturalized in temperate regions around the world. The species occurs in all the provinces, the Northwest Territories, and the Yukon. It is an important weed of field crops in the Canadian prairies. A strongly persistent seedbank, competitive annual growth habit and high fecundity all contribute to its weedy nature and ensure that it will be a continuing problem. Several cases of herbicide resistance have been documented for natural populations of S. arvensis in Canada, including biotypes resistant to: i) Group 2 herbicides, which inhibit acetolactate synthase (ALS), from Manitoba in 1992 and Alberta in 1993; ii) Group 4 herbicides or synthetic auxins from Manitoba in 1991; and iii) Group 5 herbicides, which inhibit photosynthesis at photosystem II, from Ontario in 1983. The species is a close relative of Brassica nigra (L.) Koch, black mustard, and is capable of limited genetic exchange with the Brassica crop species under laboratory hybridization conditions either by conventional crossing or with the aid of ovary/embryo recovery techniques.

“…Several species of oligophagous leaf beetles (Coleoptera: Chrysomelidae) also have been reported to show preference for some host plants over others. For example, the striped ßea beetle, Phyllotreta striolata (F.) was shown to discriminate among its host plants in the family Brassicaceae, preferring some hosts such as Brassica oleracea, B. napus, and B. campestris over B. juncea (L.) Czern and B. nigra (L.) Koch (Lamb andPalaniswamy 1990, Anderson et al 1992). The Colorado potato beetle, Leptinotarsa decemlineata (Say) also demonstrated host preference to its host plants, preferring potato (Solanum tuberosum L.) over tomato (Lycopersicon esculentum L.) and eggplant (Solanum melongena L.).…”

The yellowmargined leaf beetle, Microtheca ochroloma Stål (Coleoptera: Chrysomelidae), is an introduced pest of cruciferous crops in the southern United States, and arguably the most damaging pest of organic crucifer vegetable production in the region. Studies were conducted in the greenhouse and laboratory to investigate host finding and acceptance preference of M. ochroloma on four commonly grown cruciferous crops: cabbage (Brassica oleracea L. variety capitata), collards (B. oleracea L. variety acephala), napa cabbage [B. pekinensis (Lour.)], and turnip (B. rapa L.) First, adult beetles were allowed to choose among the four plants in a multiple-choice greenhouse cage experiment and host preference was evaluated by using three parameters: number of beetles on each plant, number of larvae on each plant, and plant damage ratings. The results showed that M. ochroloma adults actively discriminated among the four host plants, with significantly higher numbers recorded on turnip and napa cabbage than on cabbage or collards. Significantly higher numbers of larvae also were recorded on turnip and napa cabbage starting on day 10. Similarly, higher damage ratings were recorded on turnip and napa cabbage than on the remaining two hosts. Results of four-choice olfactometer experiments, which compared attraction of M. ochroloma to headspace volatiles of the four host plants, demonstrated that host preference is mediated primarily by plant volatiles. Both sexes were significantly more attracted to napa cabbage than to the remaining treatments, with turnip being the second most attractive plant. These results confirm that turnip and napa cabbage are two preferred host plants of M. ochroloma, and may support the development of a trap crop system and attractant-based strategies for managing M. ochroloma in crucifer production.

“…Feeding tests have been used before to quantify resistance in Brassica crops to several insect pests ( Dunn & Kempton, 1976;Eigenbrode et al , 1990;Lamb & Palaniswamy, 1990 ). Picoaga et al (2003) evaluated the performance of several kale varieties from northwestern Spain to lepidopterous pests and found variation in resistance.…”

Abstract1 The objectives of this work were to study the resistance of six kale (Brassica oleracea acephala group) varieties to cabbage moth Mamestra brassicae (L.) expressed as antibiosis and to determine the effect of plant age on larval survival and development.2 The influence of plant age on resistance was determined using leaves from seedlings and from mature plants. Survival and development of M. brassicae larvae and feeding rates were determined in laboratory bioassays.3 Leaves from seedlings were more suitable than those of mature plants for establishing differences in resistance. There were significant differences between kale varieties in larval survival, growth rate, leaf feeding, and time to pupation but not pupal weight. The varieties MBG‐BRS0031, MBG‐BRS0351, and MBG‐BRS0287 reduced survival of M. brassicae larvae. Larvae that fed on MBG‐BRS0060 were the heaviest and took the longest time to pupation. MBG‐BRS0031 was consumed significantly less by larvae than were all the other varieties examined. Leaves from mature plants of MBG‐BRS0142 and MBG‐BRS0170 were defoliated significantly less than those of other varieties.4 In conclusion, the variety MBG‐BRS0031 may be a promising source of resistance to M. brassicae. Leaf antibiotic resistance was shown to play a role in defense against M. brassicae attack but it is not the only possible mechanism of resistance.
