Several beech trees on Prince Edward are showing signs of an invasive species called the beech leaf-mining weevil. These weevils can disrupt the flow of nutrients and kill entire trees. Simon Wilmot, coordinator for the P.E.I. Invasive Species Council, said it’s uncertain how much damage the weevil will cause to the Island’s beech trees, but “it can spread easily.” …”It most likely came over in some firewood from Nova Scotia,” he said. …Wilmot said unfortunately there is no effective way to fight against the weevil. There is an environmentally friendly insecticide called TreeAzin that can be injected directly into beech trees and kill weevil larvae. However, the insecticide must be injected on a regular basis and therefore would not be an efficient large scale solution. …The Invasive Species Council asks anyone who spots weevil damage on beech trees to contact them.
