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 ...

Zbiranje genskih virov oljne ogrščice (Brassica napus ssp. napus L.) iz različnih habitatov v Sloveniji

Acta Agriculturae Slovenica, 2012
Oljna ogrščina (Brassica napus L.) se v naravi pojavlja v različnih habitatih, njena prisotnost izven pridelovalnih površin pa omogoča spontan prenos peloda v času cvetenja.

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.

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 ...

The role of plant phenology in the host specificity of Gephyraulus raphanistri (Diptera: Cecidomyiidae) associated with Raphanus spp. (Brassicaceae)

European Journal of Entomology, 2008
Recent host records for Gephyraulus raphanistri (Kieffer), a flower-gall midge, show restriction to Raphanus raphanistrum throughout Europe. Gephyraulus raphanistri has never been reported infesting commercially grown Brassica crops.

Transcriptomic resources and functional validation of RNAi in the cabbage seedpod weevil, Ceutorhynchus obstrictus

Pest Management Science, EarlyView.
Transcriptome sequencing of Ceutorhynchus obstrictus revealed RNA interference (RNAi) targets; double‐stranded RNA microinjection reduced transcript levels and increased mortality, with αCOP and Rop showing strongest lethal effects, indicating promising RNAi‐based pest control candidates.

Introgressed Brassica napus × Sinapis alba enhance resistance to the crucifer flea beetle (Phyllotreta cruciferae)

Pest Management Science, EarlyView.
This study demonstrates that Brassica napus lines with Sinapis alba introgressions enhanced resistance against Phyllotreta cruciferae, resulting in reduced feeding damage and improved seedling physiological performance. The introgressed lines showed strong potential as genetic resources for developing more resilient and sustainable canola varieties ...

The negative effects of an allelopathic invader on native plant photosynthesis are amplified after tree canopy closure

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Many invasive plants produce antimicrobial allelopathic compounds that disrupt plant–fungal symbioses of native species in the communities they invade, influencing nutrient and water provisioning that support photosynthesis.
