Surveillance of grape berry moth, Paralobesia viteana Clemens (Lepidoptera: Tortricidae), in Virginia vineyards
… pheromone lure design and the activity of the grape berry moth, Paralobesia viteana, flight and infestation across three years of study. In my lure evaluations, I found all commercial lures contained impurities and inconsistencies that have implications for management. First, sex pheromone …

The role of Gamma-aminobutyric acid and Hydrogen peroxide in cell death in grape berry development
… vitality (i.e., cell death) in the mesocarp of grape berries occurs during ripening. However, cell death is genotype-dependent and modulated by increasing temperatures and drought. Cell death and associated berry shrivel negatively affect the grape quality and wine chemistry. The causes of cell …

Mating disruption in apple orchards: dispenser release rates, generic blends and community impact
… Pacific Biocontrol codling moth, one AgriSense grape berry moth and two Pacific Biocontrol grape berry moth dispensers were studied using gravimetric measurements. It was found that the addition of titanium dioxide to the polyethylene mixture significantly reduced the release rate of the …

Effect of Protective Covers Against Biotic and Abiotic Disorders for Grape Production in Virginia
Grapes (Vitis spp.), globally cultivated for wine and other grape-based products, are susceptible to various diseases, pests, and disorders. These challenges are particularly pervasive in Virginia and viticultural regions in similar climates. Thus, growers routinely use insecticides and fungicides …

A comparative analysis of the metabolomes of different berry tissues between Vitis vinifera and wild American Vitis species, supported by a computer-assisted identification strategy
Grape (Vitis vinifera L.) is among the most cultivated plants in the world. Its origin traces back to the Neolithic era, when the first human communities started to domesticate wild Vitis sylvestris L. grapes to produce wines. Domestication modified Vitis vinifera to assume characteristics imparted …

Within the skin: Grape berries during the mature stages of ripening
… systems biology approach was used to investigate berry skins of three red- (Cabernet Sauvignon, Merlot, Pinot Noir) and two white-skinned (Chardonnay, Semillon) wine grape cultivars. Identical sample aliquots were analyzed for transcripts by a grapevine whole genome oligonucleotide microarray and …

Characterisation of the Auxin Signalling Pathway in Vitis vinifera L. cv. Shiraz
… has been found to be a repressor of ripening in grapes, and a decrease in berry auxin concentration is required to allow the initiation of ripening. To investigate the role of the auxin signalling pathway in grape, 19 VviARF transcription factors, 23 VviIAA repressors and six VviAFB receptor …

Investigating peduncle colour evolution and chemistry during ripening in Vitis vinifera L. cv Shiraz
… investigation of how the various sections of the grape stem (peduncle and rachis) in Vitis vinifera L. cv Shiraz evolve in terms of their colour and chemical attributes during the ripening period and is compared to the prototypical berry ripeness parameters (⁰Brix, pH, TA, etc) over three seasons. …

Heat wave mitigation strategies for wine grape production and measures of the impact of heat on berry ripening and wine composition
Loss of berry mass, commonly referred to as berry shrivel, can occur in some cultivars late in ripening. This phenomena is particularly common in Shiraz where it has been linked to a decrease in berry cell vitality (cell death) at high sugar concentrations. Moreover, both cell death and loss of …

Identification of grapevine Pectate Lyase genes altering Berry Texture during ripening
… in winemaking and as a fresh fruit (table grapes). Several parameters determine consumer acceptance in the table grape market, including berry size, aroma, flavour, and texture. While consumers perceive berry texture as an indicator of fruit freshness, for producers, the firmness is a …
