摘要
林地清理、开隔离带、林分改造等营林措施，对压低松褐天牛的危害有明显作用，林地清理虫口密度减退率达９１．０％，隔离带可有效阻止松褐天牛的自然扩散，局部林分改造；林分被害率可减少５５．７％。
some management measures,such as forest land cleaning,isolation belt opening and stand transformation, had significant function of decreasing damage of Monochamus alternatus.forestland cleaning could decrease density of Monochamus alternatus population by 91.0%; isolation belt could effectively prevent M onochamus alternatusfrom naturally diffusing; local stand transformation could decrease damage rate of forest by 55.7%.
