Molecules, 2019 Crops, such as white cabbage (Brassica oleracea L. var. capitata (L.) f. alba), are often infested by herbivorous insects that consume the leaves directly or lay eggs with subsequent injury by caterpillars.

Pest Management Science, EarlyView.SYN‐A, a naturally derived synergist, inhibited key metabolic pathways associated with pyrethroid insecticide resistance in cabbage stem flea beetle (CSFB) and its parasitoid Microctonus brassicae. SYN‐A restored pyrethroid efficacy against resistant CSFB allowing up to 80% reduction in application rates.

Control of Flea Beetles on Cabbage, 1995
, 1996 Cabbage was transplanted on 13 Jun at the Vegetable Crops Research Farm near Geneva, NY. Plots consisted of two 10-ft rows on 36-inch centers with 18-inch plant spacing. Treatments were replicated 4 times in an RCB design.

The conservation of saproxylic beetles in boreal forest [PDF]
, 2006 Forest management has altered the age structure, tree species composition and dead wood availability of Swedish boreal forests. As a consequence, many saproxylic (wood living) insect species have decreased in abundance and many species are threatened ...

Pest Management Science, EarlyView.Genotype and cropping system influenced oilseed rape ecophysiological traits, including glucosinolate compounds (glucoraphanin, glucobrassicanapin, and butyl‐glucosinolates) and biomass, which were linked to Psylliodes chrysocephala larval infestation, with varietal effects stronger than faba bean companion planting.

Pest Management Science, EarlyView.The cabbage stem flea beetle (Psylliodes chrysocephala) is a major pest of winter oilseed rape (Brassica napus). We tested B. napus and Sinapis alba seedlings for feeding resistance and underlying chemical defenses. S. alba was least damaged, while metabolite profiles revealed resistance‐linked compounds, highlighting breeding potential for insect ...

Pest Management Science, EarlyView.We screened a panel of 98 Brassicaceae genotypes (97 Brassica napus and 1 Sinapis alba) for cabbage stem flea beetle (Psylliodes chrysocephala) larval antibiosis. We found limited evidence for antibiosis across B. napus but consistent antibiosis in S. alba. Brassicaceae relatives may therefore better inform resistance traits for breeding.

HortScienceFeeding damage from flea beetle and harlequin bug reduces the marketability of brassica crops, including bok choy and napa cabbage. Fine-mesh row covers can be used as a pest management strategy to augment, reduce, or replace organic-compliant ...

Flea Beetle Control in Canola, 1995 [PDF]
Arthropod Management Tests, 1996 Abstract Plots were established at the Washington State University Animal Science Farm in Pullman, WA. Treated and untreated seed were planted on 19 May with a small plot drill at a seeding rate of 6 lb/acre in 7 rows, 6 inches apart. The late seeding date insured an even distribution of flea beetle adults.
