Changes of Scots Pine Phyllosphere and Soil Fungal Communities during Outbreaks of Defoliating Insects

摘要: Outbreaks of forest pests increase with climate change, and thereby may affect microbial communities ecosystem functioning. We investigated the structure phyllosphere soil during defoliation by nun moth (Lymantria monacha L.) (80% defoliation) pine tree lappet (Dendrolimus pini (50% in Scots forests (Pinus sylvestris Germany. Ribosomal RNA genes fungi bacteria were amplified polymerase chain reaction (PCR), separated denaturing gradient gel electrophoresis (DGGE), subsequently sequenced for taxonomic assignments. Defoliation both changed dominant fungal (but not bacterial) taxa soil. The highly abundant ectomycorrhizal taxon (Russula sp.) soils declined, which be attributed to insufficient carbohydrate supply host trees increased root mortality. In contrast, potentially pathogenic pest outbreaks. Our results suggest that pines insect pest, change communities, indirectly contributing aggravation health.
