杜鹃属植物内生真菌的分离及对赤拟谷盗和马铃薯腐烂茎线虫的防治作用
Isolation of Endophytic Fungi in Rhododendron and Its Control against Tribolium castaneum and Ditylenchus destructor
摘要
Abstract
Twenty-two strains of endophytic fungi were screened from Rhododendron thymifolium,R.capitatum,R.anthopogonoide,and R.przewalskii using culture isolation method and their insecticidal activities were investigated.The results indicated that crude extracts of LS-Y-2 mycelium showed a better pesticide activity against Tribolium castaneum(LD50=69.31 μg/adult),crude extracts of LS-Y-2 fungal liquid showed a good bioactivity against T.castaneum(FDI=84.28%)and Ditylenchus destructor(LC50=0.06 mg/mL),crude extracts of TH-Z-1 fungal liquid showed an obvious pesticide activity against D.destructor(LC50=0.07 mg/mL),crude extracts of LS-Y-4 fungal liquid showed a better antifeedant activity against T.castaneum(FDI=73.12%),crude extracts of LS-Y-4 mycelium showed a better pesticide activity against D.destructor(LC50=0.18 mg/mL).LS-Y-2 and LS-Y-4 belong to Alternaria,TH-Z-1 belong to Trametes.关键词
