Forests are an enormous economic resource in Canada and France. Not only do they represent an immediately exploitable resource, they are renewable and sustainable. Today we find our forests under the unprecedented twin threats of climate change and species invasions due to large-scale movement of people and products across the planet. Our project focuses on extensive insect invasions due to the global seed trade. Insect seed parasites destroy conifer seed crops and are essentially invisible within seed lots shipped internationally. Parasites also serve as vectors for pathogens, as well as facilitating the establishment of other pests. Our ability to predict the influence of insects and diseases on future landscapes depends on how well we understand the relationship between immobile trees and highly mobile insects. Tree seed insects damage forests and

森林在加拿大和法国是一种巨大的经济资源。它们不仅是一种可立即开发的资源，而且是可再生和可持续的。今天，我们发现我们的森林受到前所未有的气候变化和物种入侵的双重威胁，这是由于人类和产品在地球上的大规模流动造成的。我们的项目专注于全球种子贸易造成的广泛昆虫入侵。昆虫种子寄生虫破坏针叶树种子作物，在国际运输的种子地块中基本上是看不见的。寄生虫也是病原体的媒介，也促进了其他害虫的形成。我们预测昆虫和疾病对未来景观的影响的能力取决于我们对静止不动的树木和高度移动的昆虫之间的关系的理解程度。林木种子害虫破坏森林和
