To study the effect of the invasion of on the functional relationship between woody plants and insect communities, the populations of tree species and insect communities were investigative in the Masson pine forests with different infestation durations of . In this study, the number of began to decrease sharply, whereas the total number of other tree species in the arboreal layer increased gradually with the infestation duration of . The principal component analysis ordination biplot shows that there was a significant change in the spatial distribution of woody plant species in different Masson pine forest stands. Additionally, a total of 7,188 insect specimens were obtained. The insect population showed an upward trend in stand types with the increase of pine wilt disease infection periods, which demonstrated that the insect community had been significantly affected by the invasion of . However, the insect diversity indexes were not significantly different among Masson pine forest stands. The structure of insect functional groups changed from herbivorous (He) > omnivorous (Om) > predatory (Pr) > parasitic (Pa) > detritivorous (De) in the control stand to He > Pa > Om, De > Pr after infestation in the forests. The results showed that the populations of He, Pa, and De increased after the invasion of , but the populations of Pr decreased. Moreover, the redundancy analysis ordination biplots reflected the complicated functional relationship between woody plant communities and insects after the invasion of . The present study provides insights into the changes in the community structure of woody plants and insects, as well as the functional relationship between woody plant communities and insect communities after invasion of .
为研究[某种因素]入侵对木本植物与昆虫群落功能关系的影响，在具有不同[该因素]侵染持续时间的马尾松林内，对树种种群和昆虫群落进行了调查。在本研究中，[某种树种]数量开始急剧减少，而乔木层中其他树种的总数随着[该因素]侵染持续时间的增加而逐渐增加。主成分分析排序双标图表明，不同马尾松林分中木本植物物种的空间分布存在显著变化。此外，共获得7188份昆虫标本。随着松材线虫病感染期的增加，林分类型中的昆虫种群呈上升趋势，这表明昆虫群落受到了[该因素]入侵的显著影响。然而，不同马尾松林分之间的昆虫多样性指数没有显著差异。昆虫功能群结构从对照林分中的植食性（He）>杂食性（Om）>捕食性（Pr）>寄生性（Pa）>腐食性（De），在森林受到[该因素]侵染后变为He>Pa>Om，De>Pr。结果表明，[该因素]入侵后，He、Pa和De的种群数量增加，但Pr的种群数量减少。此外，冗余分析排序双标图反映了[该因素]入侵后木本植物群落与昆虫之间复杂的功能关系。本研究为木本植物和昆虫群落结构的变化以及[该因素]入侵后木本植物群落与昆虫群落之间的功能关系提供了见解。
