Abstract
Some fungal species isolated from other fungi were tested for their capacity to degrade chitin, cellulose and laminarin. Only three entomophagous fungi degraded native chitin. However colloidal chitin was degraded by all fungi tested except four. Cellulolytic activity was mainly found in fungi with a poor performance against cucumber powdery mildew. This suggests that the capacity to produce cellulase is not important for successful mycoparasitic activity against cucumber powdery mildew. A good correlation was found between the capacity to degrade laminarin and the mycoparasitic activity of the fungi that were investigated.
