ABSTRACT
The shiitake mushroom is an aerobic fungus decomposer of wood, traditionally cultivated in oak trunks in other countries. In Brazil it is cultivated in the trunks of newly-cut Eucalyptus spp., an abundant and low-cost tree. Ease of getting the substrate and its acceptation in business, have made it the second most-consumed mushroom in the world. The Opogona sacchari moth has been found making unviable the cultivation to small and mid-size productors, because it is an insect of great distribution and with many hosts. A sample realized at 15 little farms evidenced, on averege, that 35.17% of inoculated trunks in production were infested.
