Transport engineering as a strategy to realize rapeseed's potential as a protein‐rich food

Pest Management Science, EarlyView.
The heavily pesticide‐dependent rapeseed is an under‐utilized protein source for food owing to anti‐nutritional glucosinolates. Transport engineering technology may reduce glucosinolates in seeds while increasing defense in vegetative parts. Abstract Rapeseed is the world's second‐largest oilseed crop, and the low‐value press cake that remains after ...

Integral projection models show exotic thistle is more limited than native thistle by ambient competition and herbivory

Ecosphere, 2015
Both competitors and natural enemies can limit plant population growth. However, demographic comparisons of the effects of these interactions on introduced versus co‐occurring, related native species are uncommon.

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.

Hyperspectral imaging to characterize plant–plant communication in response to insect herbivory

Plant Methods, 2018
Background In studies of plant stress signaling, a major challenge is the lack of non-invasive methods to detect physiological plant responses and to characterize plant–plant communication over time and space.

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 ...

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.

Landscape connectivity and insect herbivory: A framework for understanding tradeoffs among ecosystem services

Global Ecology and Conservation, 2015
Current theory suggests that ecosystem services in fragmented landscapes can be maintained by preserving connectivity of remaining habitat patches. However connectivity does not always influence services positively.

Impact of insect herbivory on plant stress volatile emissions from trees: A synthesis of quantitative measurements and recommendations for future research

Atmospheric Environment: X, 2020
Plants, and particularly trees, are the largest source of atmospheric volatile organic compounds globally. Insect herbivory alters plant volatile emission rates and the types of compounds that are emitted.

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 ...

Invasive plants reduce functional feeding diversity and trophic interactions of insect herbivores on a remote tropical island.

PLoS ONE
Invasive plants are a driver of global insect decline, yet their impacts on trophic interactions in insular tropical island ecosystems remain poorly understood.
