Remember when those red, spotted beetles were seemingly everywhere earlier this year?<\/p>\n

Due to warming temperatures, those pesky bugs are growing in numbers \u2014 and Brock University researchers have provided research-based strategies for managing their impact on grape and wine production in a special climate change edition of Biomolecules<\/em><\/a>.<\/p>\n

\u201cThis international collaboration between a leading viticulturalist, oenologist and industry extension specialist brought together three complementary skill sets to compile this comprehensive review and contextualize the research for winegrowers,\u201d said leading author Gary Pickering, Professor of Biological Sciences and Psychology and Researcher at Brock\u2019s Cool Climate Oenology and Viticulture Institute (CCOVI). \u201cIt is aimed at better understanding the impact climate change will have on the grape and wine industry, including considerations such as the increased presence of this invasive pest.\u201d<\/p>\n

Gary Pickering, Professor of Biological Sciences and Psychology and Researcher at Brock\u2019s Cool Climate Oenology and Viticulture Institute, was the lead author on a recent literature review in Biomolecules.<\/p><\/div>\n

The publication, “Prevalence and Management of Alkyl-Methoxypyrazines in a Changing Climate: Viticultural and Oenological Considerations<\/a>,\u201d was co-authored by Jim Willwerth, CCOVI Researcher and Assistant Professor of Biological Sciences; Andreea Botezatu (PhD \u201914), of Texas A&M University; and Margaret Thibodeau, who successfully defended her PhD thesis in Biological Sciences at Brock earlier this year.<\/p>\n

The authors explored the impact that climate change will have on the presence of methoxypyrazines, a class of molecules that contribute \u2018green\u2019 characteristics to wine.<\/p>\n

CCOVI has been a world leader on research in this area.<\/p>\n

These chemicals are naturally occurring in some grape cultivars, and can, in low levels, contribute favourably to the overall flavour profile of certain wines (like Sauvignon Blanc, for example).<\/p>\n

In higher quantities, however, they produce an undesirable flavour that is likened to green pepper or peanut butter.<\/p>\n

The compounds can also be introduced when Harmonia axyridis, or multi-coloured Asian ladybeetles, are inadvertently crushed and incorporated in with the grapes at harvest.<\/p>\n

Andreea Botezatu ((PhD \u201914), of the Department of Horticultural Sciences at Texas A&M University, returned to Brock earlier this year to co-author a recent literature review in Biomolecules.<\/p><\/div>\n

While these invasive pests have been present in wine-growing regions around the world for the last decade or so, warmer temperatures in Canada are allowing them to live longer and reproduce in higher numbers.<\/p>\n

\u201cThey usually die off because our winters are so cold, but they are now surviving longer and since they are able to proliferate early in the season \u2014 and can actually get two or three generations in one season \u2014 there\u2019s now more around on a regular basis,\u201d Pickering explained.<\/p>\n

The article outlines that there are insecticides and repellents that have shown promise for managing the presence of these ladybeetles in the vineyard, as well as remediation practices that can take place in the winery. The authors also note that viticultural practices, such as implementing a vine training system to increase temperature and light exposure, also have potential to manage concentrations of the chemical in its naturally occurring form in the grape.<\/p>\n

\u201cHow the grapes respond to climate change is going to be dependent on the part of the world, and even the appellation that we\u2019re talking about,\u201d Pickering added. \u201cFor instance, we have a really interesting story here in Canada this vintage, with our two major grape growing regions \u2014Ontario and B.C. \u2014 experiencing polar opposites in terms of weather and related vineyard stressors, yet both scenarios are predicted from the climate change models.\u201d<\/p>\n

That\u2019s why the collaborative work that CCOVI and its partners do to support the grape and wine industry is more important than ever.<\/p>\n

\u201cIncreased frequency of extreme weather events happening during the growing season are going to have different impacts, so it\u2019s important for us to continue doing research on flavour compounds such as methoxypyrazines to better understand how to mitigate the impacts of climate change and maintain the high quality of our wines here in Canada,\u201d Pickering said.<\/p>\n","protected":false},"excerpt":{"rendered":"
