Phylloxera is a plant-louse insect, specifically *Daktulosphaira vitifoliae*, that devastates grapevines by feeding on their roots. This tiny pest can cause severe damage, leading to vine decline and death. It's a major threat to vineyards worldwide. 🍇 Most grapevines are now grafted onto resistant rootstocks to combat phylloxera. Think of it as the arch-nemesis of the wine industry. 🍷
