８０年代以来，云南全省云南松林区遭受纵坑切梢小蠹的猖獗危害，造成大量林木死亡。１９９２年在昆明市现有的云南松与栎类、云南松与华山松、云南松与滇油杉混交林及云南松纯林中，设置１１块定位观察样地，观察云南松混交林蠹害发生情况，１９９２～１９９５年经过４年的观察，混交林平均株受害率１０．９％，纯林平均株受害率４８．９％。混交林比纯林降低纵坑切梢小蠹危害率３８．０％。混交林内由于乔、灌、草种类的多样性，带来纵坑切梢小蠹天敌种类的多样性，有效地抑制纵坑切梢小蠹的发生与发展，形成有虫不成灾的生态环境
Since the 1980s, the pine forests in Yunnan Province in Yunnan province have suffered from the rampant damage caused by the beetles and the death of a large number of trees. In 1992, a total of 11 plots of observation and observation were set up in Kunming, Yunnan, China with Pinus yunnanensis, Quercus mongolica, Pinus yunnanensis, Pinus yunnanensis, Pinus yunnanensis, and Pinus yunnanensis forest in Kunming. After 4 years of observation from 1992 to 1995, the average damage rate of mixed forest was 10.9% and the average damage rate of pure forest was 48.9%. The mixed forest was lower than the pure forest to cut the diameter of cut pipiens pachyderm 38.0%. Due to the diversity of Qiao, Shrub and grass species in mixed forest, the diversity of natural beetles in the vertical borer, Betula pendulifolium, is diversified, which effectively restrain the occurrence and development of Betula albacter.
