We experimentally reanalyzed the classic interaction between Pieris rapae, a specialist lepidopteran herbivore, and isothiocyanates (mustard oils) that are characteristic phytochemicals of the Brassicaceae. Previous investigations have suggested that P. rapae is unaffected by isothiocyanates. Using whole plants, root extracts, and a microencapsulated formulation of allyl isothiocyanate, we now show that isothiocyanates reduce herbivore survival and growth, and increase development time, each in… 

Nematicidal potential of Brassicaceae

The present review paper focuses on GLSs role as bionematicides and the current knowledge on the efficacy of these phytochemicals against the most common phytoparasitic nematodes affecting crops of agriculture importance such as tomato, potato and grapevine.

Isothiocyanate metabolism in generalist lepidopteran herbivores

The presence of GSH conjugates in larval faeces after consumption of crucifers suggests isothiocyanate-detoxification via GST (glutathione-S-transferase) activity in caterpillars.

Glucosinolates: The Phytochemicals of Nutraceutical Importance

Iso-thiocyanates, one of the hydrolyzed products, show best anti-carcinogenic activity and has recently attracted intense research interest because of their cancer chemo-protective attributes.

Glucosinolate and Trichome Defenses in a Natural Arabidopsis lyrata Population

In a quantitative genetic experiment with the out-crossing perennial Arabidopsis lyrata spp, phenotypic and genetic correlations between candidate defense traits and insect resistance suggested that A. lyrata resistance was conferred by a combination of indole GS amount and trichome density, and, to a lesser extent, aliphatic GS ratios and leaf thickness.

Glycine Conjugates in a Lepidopteran Insect Herbivore—The Metabolism of Benzylglucosinolate in the Cabbage White Butterfly, Pieris rapae

It is shown that P. rapae larvae convert benzylglucosinolate to phenylacetylglycine, which is released in their faeces, and the first description of such conjugates from lepidopteran insects is described.

Mechanisms of Isothiocyanate Detoxification in Larvae of Two Belowground Herbivores, Delia radicum and D. floralis (Diptera: Anthomyiidae)

Like aboveground herbivores, belowground herbivores are confronted with multiple plant defense mechanisms including complex chemical cocktails in plant tissue. Roots and shoots of Brassicaceae plants

Brassicaceae: a rich source of health improving phytochemicals

This review summarizes information on the phytochemical profile of Brassicaceae plants, with a special regard to glucosinolates and their derived degradation products, the isothiocyanates, and their role as antioxidant and cancer protective metabolites is discussed.

Alkaloid concentration of the invasive plant species Ulex europaeus in relation to geographic origin and herbivory

The results showed that pod infestation rate by the seed predator Exapion ulicis and infestation by the rust pathogen Uromyces genistae-tinctoriae were negatively correlated to concentration of the QA lupanine, suggesting that no evolution of decreased resistance occurred after gorse lost its enemies.

Effect of volatiles derived from Brassica plants on the growth of Sclerotinia sclerotiorum

The study of hydrolysis substrate variations shows that oxalic acid concentrations and pH levels, even at physiological rates of ambient concentration and pH, did not affect the GSL-M defence system during fungal activity in the host tissues.



Chemical barriers to adaptation by a specialist herbivore

The assumption that specialist herbivores such as the parsnip webworm are adapted to hostplant chemistry, and are therefore unaffected by chemical variation in hostplants, was tested.

Disarming the mustard oil bomb

Sulfatase activity of this enzyme largely prevents the formation of toxic hydrolysis products arising from this plant defense system, thus enabling diamondback moths to use a broad range of cruciferous host plants.

Induced responses in Nicotiana attenuata affect behavior and growth of the specialist herbivore Manduca sexta

It is proposed that induced plants growing in close competition with an uninduced conspecific may offset the fitness costs of these induced responses and perhaps obtain a fitness benefit by motivating herbivores to move to their neighboring competitors.

Wound‐induced increases in the glucosinolate content of oilseed rape and their effect on subsequent herbivory by a crucifer specialist

Damage to the oilseed rape plant by the cabbage stem flea beetle induces systemic changes to the glucosinolate profile, which implies that other aspects of the damage response are being induced by the jasmonic acid treatment and having a negative effect on subsequent herbivory.

Allylglucosinolate and Herbivorous Caterpillars: A Contrast in Toxicity and Tolerance

Larval growth of Spodoptera eridania, a generalist feeder, is inhibited by high but not by low concentrations of the compound, while that of Pieris rapae, a crucifer specialist, is not affected even by artificially high concentrations of allylglucosinolate.

Experience‐based food consumption by larvae of Pieris rapae: addiction to glucosinolates?

Bioassays of cowpea extracts failed to show any deterrent activity and supported the conclusion that addiction to glucosinolates is responsible for the fixation of P. rapae larvae on their host plants.

Induced responses in three alkaloid-containing plant species

It is hypothesized that the nature of the response is not a feature of the type of secondary metabolite, but is related to whether the plants are damaged mainly by generalist or by specialist herbivores.

Milkweed latex and cardenolide induction may resolve the lethal plant defence paradox

It is these sequestering specialists that pose a paradox for plants because greater investment in toxic chemical defences by a plant may lead to enhanced herbivore fitness and reduced plant fitness.

Specificity of induced resistance in wild radish: causes and consequences for two specialist and two generalist caterpillars

Variation in the specificity of induction and effects of induced plant resistance was found and these results add a novel level of complexity to interactions between plants and leaf chewing caterpillars, suggesting that coevolution can only be diffuse.

Influence of foliar glucosinolates in oilseed rape and mustard on feeding and growth of the bertha armyworm,Mamestra configurata Walker

The data suggest that foliar isothiocyanate-releasing glucosinolates may provide some degree of plant protection from polyphagous insects.
