Abstract:
:Trichothecene mycotoxins were produced byFusarium sporotrichioides DAOM 197255 isolated from a spruce budworm cadaver. An extract from the culture filtrate containing these metabolites was toxic to budworm when ingested at concentrations as low as 10 ppm in diet, and survivors were predisposed to infection with a fungal entomopathogen. The possible role of these metabolites in the balsam fir-spruce budworm habitat is discussed.
