ANR-Megastigmus and conifers: the biology of invasion

森林是加拿大和法国的巨大经济资源。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面临着前所未有的双重威胁，即气候变化和物种入侵，这是由于全球范围内大规模的人员和产品流动造成的。我们的项目重点关注由于全球种子贸易而引起的广泛的昆虫入侵。昆虫种子寄生虫破坏针叶树种子作物，在国际运输的种子批次中基本上是不可见的。 寄生虫也是病原体的载体，并促进其他害虫的建立。我们预测昆虫和疾病对未来景观影响的能力取决于我们对不移动的树木和高度移动的昆虫之间关系的理解程度。树种害虫破坏森林，

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.
