Abstract
An unusual mass outbreak of the pale tussock moth (Calliteara pudibunda) occurred in beech stands in the White Carpathians Mts. and in the Hostynske vrchy hills in 1992 and 1993. An epizootic of nuclear polyhedrosis virus (NPV) was the basic mass outbreak regulating factor. A mycotic disease caused by the fungus Paecilomyces farinosus was also important. Insect parasitoids were a less important factor that contributed to a reduction in the pale tussock moth gradation. Dominant parasitoids involved ichneumon flies of the species Pimpla hypochondriaca (=instigator) and Phobocampe sp. The species P. hypochondriaca parasitized 8.6 to 13.2 % of larvae and pupae.
