气候变暖使许多森林害虫迅速蔓延。入侵者的适应潜力在很大程度上影响着入侵物种向新地区扩散的程度，以及它们对入侵生态系统的影响程度。为了衡量的适应潜力的入侵（冬蛾）和潜在的入侵落叶蛾物种（稀缺土蛾），我们研究了生活史参数在两个环境中的一组遗传多样性的主机树和比较性状与居民蛾物种（秋蛾）。此外，由于宿主基因型的生活史参数的变化进行了计算和比较。
The warming climate has enabled a rapid expansion of many forest pests. The adaptation potential of the invaders affects largely on how well the invasive species can spread to new areas and in what extent can they have an impact on the invaded ecosystem. To measure the adaptation potential of an invasive (winter moth) and a potentially invasive defoliating moth species (scarce umber moth), we examined life history parameters in two environments on a set of genetically diverse host trees and compared the traits with those of a resident moth species (autumnal moth). In addition, variations in life history parameters due to host genotype were calculated and compared.
