- Abstract
【Objective】 To understand the species or group and analysis on the function of fungi associated (symbiotic) with Scolytus schevyrewi in fruit trees in the hope of providing basic information for utilization of these symbionts and revealing the damage mechanism of S.schevyrewi.【Method】 S.schevyrewi adults were collected from infested fruit trees in Shule, Yingjisha and so on, the species and group of fungi associated with S.schevyrewi were identified by using MiSeq high-throughput sequencing technology and indoor isolation and culture methods.The functions of the fungi were analyzed by using FUN Guild and referring to relevant literatures.【Result】 The fungi belonged to 7 Phylum, 24 Class, 66 Order, 124 Family, 221 Genus.The dominant fungal microflora of the surface of S.schevyrewi were Geosmithia, Saccharomycetales, Byssochlamys and Wickerhamomyces, which accounted for 29.55%, 19.50%, 8.20% and 6.07% of the communities, respectively.The dominant fungal microfloras of the gut of S.schevyrewi include Geosmithia, Pleosporales, Gibellulopsis, accounting for 42.14%, 15.61% and 6.97%, respectively.The fungi were mainly saprotroph, plant pathogen, pathotroph- saprotroph and animal pathogen.S.schevyrewi adults, which infested apricot, plum, peach and almond trees, coexisted with a variety of plant-pathogenic fungi.The proportion of plant-pathogenic fungi was the highest in S.schevyrewi adults that infested peach trees, which was 19.06%.Thirteen associated fungi were isolated and identified in laboratory.Among them Geosmithia pallida, Yamadazyma Mexicana and Cladosporium Macrocarpum were plant pathogens.Wickerhamomyces Silvicola, Meyerozyma Guilliermondii, Rhodotorula mucilaginosa and Aureobasidium pullulans were antagonists of the plant-pathogens.【Conclusion】 It was common to carry and spread plant-pathogens by S.schevyrewi in Xinjiang fruit trees.When preventing and controlling S.schevyrewi, attention should be paid to the prevention and control of fruit tree trunk diseases, so as to prevent the two kinds of pests from synergistic damage and aggravating the damage.The beneficial antagonistic fungi associated with S.schevyrewi should be exploited and used as biological control fungi for some plant diseases.
