Two larval pathogens of Epinotia aporema Wals. were determined from samples collected on alfalfa: a bacteria, belonging to the Streptococcus genera and a granulosis virus, which apparently is not yet dis- tributed over all the E. aporema affected area. The mortality caused by the bacteria during the win ter months and by the granulosis virus in the areas where it was detected, seems to be important in the regulation of the E. aporema population.
