Sažetak
The entomopathogenic fungus Entomophaga maimaiga Humber, Shimazu & Soper (Entomophtorales: Entomophtoraceae) was found for first time in populations of gypsy moth, Lymantria dispar (L.) (Lepidoptera: Erebidae), in Greece and the Former Yugoslavian Republic of Macedonia (FYROM) after its introduction in Bulgaria in 1999. Monitoring studies were conducted in 2012 in oak stands in three sites in the Xanthi region in Greece, and in three sites in FYROM in the Prilep region. Gypsy moth larvae, predominately in fourth to sixth instar, were collected in May and June. During laboratory rearing, mortality of gypsy moth larvae collected in two sites in Greece ranged from 36.4–89.3%. Larval mortality of L. dispar in the three sites in FYROM ranged from 16.7–87.8%. Dead larvae were analysed under light microscopy for presence of E. maimaiga and other entomopathogens. E. maimaiga was recorded from one site in Greece (Kidaris vill.), and in all study sites in FYROM (Toplica, Belovodica and Krushevo vill.). Azygospores of E. maimaiga were found in the bodies of 78.6% of gypsy moth larvae from Kidaris, and in 8.3–16.3% of the larvae from sites in FYROM. Recent records of E. maimaiga in Serbia and the European part of Turkey, and present findings in Greece and FYROM, indicate that the fungus most probably has invaded gypsy moth populations in other parts of Balkan Peninsula.
