Field investigation of glucosinolates and morphological traits in mitigating Psylliodes chrysocephala larval infestation through crop varieties and companion planting

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.

Seedling resistance and chemical defenses against Psylliodes chrysocephala: the roles of seed age and sinapinic acid in Sinapis alba and Brassica napus

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 ...

Recent speciation in three closely related sympatric specialists: inferences using multi-locus sequence, post-mating isolation and endosymbiont data. [PDF]

PLoS ONE, 2011
Shifting between unrelated host plants is relatively rare for phytophagous insects, and distinct host specificity may play crucial roles in reproductive isolation.

Larval antibiosis to cabbage stem flea beetle (Psylliodes chrysocephala) is absent within oilseed rape (Brassica napus)

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.

Flea beetle (Phyllotreta spp.) management in spring‐planted canola (Brassica napus L.) on the northern Great Plains of North America

GCB Bioenergy
Canola (Brassica napus L. and B. rapa L. [Brassicales: Brassicaceae]) is a major oilseed crop grown globally as a source of vegetable oil, animal feed and biofuel feedstock.

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.

Behavioural manipulation of the cabbage stem flea beetle (Psylliodes chrysocephala L): Prospects for push–pull strategies in oilseed rape

Pest Management Science, EarlyView.
Behavioural manipulation of Psylliodes chrysocephala provides promising opportunities for sustainable pest management in oilseed rape systems. This review synthesises evidence on glucosinolates and their volatile isothiocyanate derivatives as phagostimulants and attractants, alongside the repellent or antifeedant effects of non‐host plants, plant ...

Intercropping with legumes can reduce insect pest pressure but does not increase yield in winter oilseed rape (Brassica napus L.)

Pest Management Science, EarlyView.
Intercropping winter oilseed rape with spring faba bean reduced cabbage stem flea beetle and pollen beetle damage but also reduced crop yield. Sowing the intercrop simultaneously with winter oilseed rape was essential to maximize crop protection against cabbage stem flea beetles. Abstract BACKGROUND Winter oilseed rape (WOSR, Brassica napus) is a major
