摘要
通过对沙地樟子松天然林火烧迹地不同火烧程度过火木病虫害发生情况的调查和分析,明确火烧迹地过火木病虫害发生规律。结果表明,不同火烧迹地火烧木病虫害主要是云杉大黑天牛、云杉小黑天牛、灰长角天牛和小蠹虫;随着火烧程度的增加,蛀干害虫的寄生率和虫口密度显著增加。
Through the investigation and analysis of the occurrence of fire wood pests and diseases in the firewood of Pinus sylvestris var.mongolicain the sandy land,the occurrence rule of the fire wood pests and diseases in the fire burned areas was determined.Result shows that firewood diseases insect pests of different fire burned areas are mainly Monochamus urussovi,Monochamus sutor,Acanthocinus aedilis and Scolytidae.With the increase in the degree of fire,the parasitism rate and density of insect populations of the stem pests increase significantly.
