月季线虫病风险初步分析

通过月季线虫种类的调查、鉴定及月季线虫病害危险性分析，结果表明：国内月季线虫的种类较少，只有12属14种，其中6种线虫即卢兹垫刃线虫（Tylenchus luci)、诺曼琼斯丝尾垫刃线虫（Filenchus norhanjonesi)卡文斯螺旋线虫（Helicotylenchus cavenessi)、粗尾矮化线虫（Tylenchorhynchus crassicaudatus）、磨菇滑刃线虫（Aphelenchoides composticola)及燕麦真滑刃线虫（Aphelenchus awenae)等在国内外首次报道为月季寄生线虫，1种即双宫螺旋线虫（Helicotylenchus dihystera)为国内首次报道为月季寄生线虫；月季寄生线虫对中国月季生产存在潜在的危险性，特别是以北方根结线虫（Meloidogyne hapla)、伤残短体线虫（Pratylenchus vulus)、双宫螺旋线虫（H.dihystera)、裂尾剑线虫（Xiphinema diversicaudatum)、印度剑线虫（X.indica)等5种线虫危害最严重。对中国来说，应加强对北方根结线虫（M.hapla)、伤残短体线虫（P.vulnus)、裂尾剑线虫（X.diversicaudatum)等3种线虫的检疫。

Preliminary Study on Nematode Risk to Rose

Investigation of rose nematode species shows that 14 species in 12 genera of plant parasite nematodes associated with rose has been encounted in China. 6 species of Tylenchus luci,Filenchus monhanjonest,H. cavenessi,Tylenchorhynchus crassicaudatus, Aphelenchoides composticola and Aphelenchus avenae were firstly reported as rose nematode; and 1 speciese of Helicotylenchus dihystera was reported as rose nematode in China. The result of rose nematode risk analysis shows that rose nematode is a latent risk to rose production in China. M. hapla, Pratylenchus vulus, Xiphinema diversicaudatum, X. indica and Helicotylenchus dihystera are more dangerous nematodes to rose production. Chinese cultivators should pay more attention to quarantine M.hapla,Pratylenchus vulus and X. diversicaudatum .;
