A natural defence for vineyard pests (BDIS)

Mealybugs may be tiny, but they’re causing big problems for Aotearoa New Zealand’s wine industry by spreading the destructive Grapevine leafroll-associated virus 3 (GLRaV-3). In this episode of Scigest, host and scientist Nicola Sullivan chats with fellow scientist Michelle Thompson about her Endeavour Fund research exploring whether some grapevines are naturally better at defending themselves against these pests. With support from Lincoln University, Michelle’s team is using an ultra-fine gold wire and a technique called electropenetrography to track how mealybugs feed on Sauvignon blanc grapevines. The goal? To develop smart, resilient rootstocks that help future-proof our vineyards. Hit play to explore the science that could help future-proof your favourite vintage.
