Description: The establishment and prevalence of the entomopathogenic fungus Entomophaga maimaiga, (Zygomycetes, Entomophthorales), introduced into two gypsy moth populations in Bulgaria, was monitored during 2000-2004. In the Karlovo Region population, where E. maimaiga was introduced in 1999, the fungus was recovered every year and the prevalence of infection varied from 6.1% to 15.9% A microsporidian infection caused by an Endoreticulatus sp. (Protista, Microsporidia) was also recorded every year and the prevalence varied from 2.1% and 5.0%. In the Svoge Region population, where E. maimaiga was introduced in late 2000 and first found in 2002, the prevalence of infection varied from 8.8% to 13.8%. Larval parasitism caused by Cotesia melanoscela, Protapanteles liparidis (Hymenoptera, Braconidae) and species of tachinids (Diptera, Tachinidae) was also recorded in the larvae of both populations. We provide a rationale as to why other countries should consider introducing E. maimaiga for biological control of Lymantria dispar populations.
