Entomophaga maimaiga, a pathogen of Lymantria dispar in Asia, was successfully introduced in Bulgaria during 1999. The first epizootics caused by this fungus occurred during 2005 and three recent epizootics occurred in the immediate vinicity of Bulgarian borders with Serbia, Greece and Turkey (6-12 km), suggesting that the fungal pathogen has spread naturally to three of the neighbouring countries. No massive Lymantria dispar outbreaks have been recorded recently in Bulgaria, possibly due to the impact of this entomopathogen. We believe it is desirable to iniciate a monitoring program and to augmentatively expand the range of E. maimaiga as an alternative to the use of chemical and Bacillus thuringiensis insecticides, which are a threat for the stability and biological diversity in oak forests of the Balkan Peninsula.
