Role of defense enzymes and phenolics in resistance of wheat crop (Triticum aestivum L.) towards aphid complex

, 2017
Herbivory damage leads to induction of rapid signals and responses in plants such as oxidative burst, accumulation of secondary metabolites and defensive proteins.

The Potato Aphid Salivary Effector Me47 Is a Glutathione-S-Transferase Involved in Modifying Plant Responses to Aphid Infestation

Frontiers in Plant Science, 2016
Polyphagous aphid pests cause considerable economic damage to crop plants, primarily through the depletion of photoassimilates and transfer of viruses.

Combined effects of canola plant density and insecticide management strategies on flea beetle abundance, canola defoliation, and yield across the Canadian prairies

Pest Management Science, EarlyView.
Increasing canola plant density reduced flea beetle abundance per plant and increased yield, independent of region or insecticide use, highlighting its potential as a component of integrated pest management. Abstract The crucifer flea beetle, Phyllotreta cruciferae (Goeze), and the striped flea beetle, Phyllotreta striolata (Fabricius) (Coleoptera ...

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 ...

Distribution and incidence of viruses in Irish seed potato crops

Irish Journal of Agricultural and Food Research, 2015
Virus diseases are of key importance in potato production and in particular for the production of disease-free potato seed. However, there is little known about the frequency and distribution of potato virus diseases in Ireland. Despite a large number of

An Immuno-Suppressive Aphid Saliva Protein Is Delivered into the Cytosol of Plant Mesophyll Cells During Feeding.

Molecular Plant-Microbe Interactions, 2016
Herbivore selection of plant hosts and plant responses to insect colonization have been subjects of intense investigations. A growing body of evidence suggests that, for successful colonization to occur, (effector/virulence) proteins in insect saliva ...

Glucosinolate hydrolysis products suppress entomopathogenic nematodes in vitro but do not protect sequestering flea beetle larvae in vivo

Pest Management Science, EarlyView.
The flea beetle's glucosinolate‐based chemical defense fails to protect larvae from nematode infection. However, the defense inhibits the nematode's symbiotic bacteria, thereby potentially impairing nematode reproduction and biocontrol success. Abstract BACKGROUND The efficacy of entomopathogenic nematodes (EPNs) in the biological control of insect ...

Host Plants Indirectly Influence Plant Virus Transmission by Altering Gut Cysteine Protease Activity of Aphid Vectors*

Molecular & Cellular Proteomics, 2016
The green peach aphid, Myzus persicae, is a vector of the Potato leafroll virus (PLRV, Luteoviridae), transmitted exclusively by aphids in a circulative manner. PLRV transmission efficiency was significantly reduced when a clonal lineage of M.

Towards an attract‐and‐reward strategy: evaluating nectar resources and HIPVs under laboratory conditions to enhance Aphelinus mali parasitism activity, a key parasitoid of Eriosoma lanigerum

Pest Management Science, EarlyView.
Euphorbia segetalis is a promising attractant insectary plant for Aphelinus mali. Meanwhile, Vicia faba and Vicia sativa are a promising nectar resource to sustain the parasitoid in early spring when the population of Eriosoma lanigerum is low, and honeydew is scarce.
