“…(Brassicaceae), commonly known as winter cress and yellow rocket, is a biennial or short-lived perennial plant that occurs in temperate regions worldwide (MacDonald and Cavers, 1991). Barbarea vulgaris has been shown to have two morphologically-distinct forms, G and P, which have hairless (Glabrous) and hairy (Pubescent) leaves, respectively, and which also differ in the content of glucosinolates and saponins, are genetically divergent, and show differences in habitat adaptation (Agerbirk et al, 2015;Agerbirk et al, 2003b;Christensen et al, 2014;Christensen et al, 2016;Hauser et al, 2012;Heimes et al, 2016;Toneatto et al, 2010). Henceforth we will refer to G-type B. vulgaris var.…”

Two types of Barbarea vulgaris R. Br. (Brassicaceae) were tested to compare their resistance and susceptibility to powdery mildew, Erysiphe cruciferarum Opiz ex L. Junell (Erysiphales: Erysiphaceae), root-knot nematode, Meloidogyne incognita (Kofoid & White) Chitwoodi (Tylenchida: Heteroderidae), and western flower thrips, Frankliniella occidentalis Pergande (Thysanoptera: Thripidae). In experiments conducted in the greenhouse, the percentage of plants showing powdery mildew symptoms ranged from 54.2 to 83.3% in P-type B. vulgaris plants and from 0 to 20.8% in G-type B. vulgaris plants.In plants infected by powdery mildew, the percentage of leaves affected was higher in Ptype than in G-type plants, ranging from 11.8 to 21.1% in P-type plants, and from 0 to 0.36% in G-type plants. Infection by powdery mildew was more likely to occur on the leaves of largest diameter. Root galling showed that G-and P-type plants were equally attacked by root-knot nematode, but the multiplication rate of the nematode was 4.1 to 7.6 times higher in P-type than in G-type plants. Significantly more leaves per plant were damaged by western flower thrips in P-type (73.1 to 88.3% of leaves affected) than in Gtype plants (2.1 to 2.9% of leaves affected). The total numbers of adult and immature thrips found per plant on P-type plants were, respectively, 29.9 and 2.5, while on G-type plants less than 0.3 adult and immature thrips were found per plant. This study indicates that Gtype B. vulgaris could be a source of resistance to powdery mildew and western flower thrips.

Several Barbarea spp. (Brassicaceae) have been tested as trap crops for the diamondback moth Plutella xylostella L. (Lepidoptera: Plutellidae). The use of trap crops can be affected by their susceptibility to other pests, especially if the purpose is to reduce insecticide use. Barbarea rupicola Moris, B. verna (Mill.) Asch., and B. vulgaris Aiton (types G and P) (Brassicaceae) were tested for their susceptibility to the cabbage whitefly Aleyrodes proletella L. (Hemiptera: Aleyrodidae). The percentage of plants showing infestation by cabbage whiteflies ranged from 50% in G-type B. vulgaris and 8.3% in B. verna to no infestation at all in B. rupicola and P-type B. vulgaris. On the other hand, 95.8% of P-type plants showed symptoms of powdery mildew, Erysiphe cruciferarum Opiz ex L. Junell (Erysiphales: Erysiphaceae), while the G type and the other Barbarea spp. were unaffected by this pathogen. Additionally, the G and P types were used in two-choice oviposition preference tests to compare their attractiveness to the small white butterfly Pieris rapae L. (Lepidoptera: Pieridae). No significant differences in total oviposition per plant were found between the two types, but within-plant differences show that the small white butterfly prefers to oviposit on the adaxial leaf side in the P type. This study indicates that in locations where the cabbage whitefly is an economic pest, B. verna, which can also be used as a dead-end trap crop for the diamondback moth, could be chosen over G-type B. vulgaris.
