根结线虫天敌真菌及其高效菌株筛选

ROOT KNOT NEMATODE-DESTROYING FUNGI AND THE SCREENING OF EFFECTIVE STRAINS

本文报道捕食和寄生南方根结线虫(Meloidogyne incognita)和爪哇根结线虫(M.javanica)的天敌真菌6属14种。其中Arthrobotrys candida A.cladodes var.macroides,A.musiformis,Monacrosporium cionopagum,M.doedycoides,Drechmeria coniospora,Harposporium crassum,H.lilliputanum,Myzocytium humicola和Verticillum coccospora为我国新纪录种。室内测定结果表明:GACA 1B(Arthrobotrys oligospora)、GACM 102(Monacrosporium doedycoides)菌株对南方根结线虫和爪哇根结线虫均具极高的捕食率,接种线虫7天后,捕食率达98%以上,接种20天后,捕食率均达100%。

Fourteen species of root knot nematode-destroying fungi were isolated from soil of England and China.Ten spacies of them have not been described in China before.The ssreening of strains to captute Mtloidogyne incognita and M.javanica showed that Arthrobotrys oligospora 1B and Monacrosporium doedycoides GACM 102 were much effective.Seven days after inoculation,more than 98% of the root knot nematodes were captured by the fungi.
