Abstract: The nun moth (Lymantria monacha /L./) is a polyphagous pest feeding on coniferous and deciduous trees in Eurasia. This paper, based on a literature review, presents an overview of the nun moth outbreaks in Czech forests from 1784 to 2010 in terms of host tree species. At least 22 genera of host trees, bushes and herbs were recorded in the Czech Republic. On the other hand 2 genera were evaluated like non-hosts and 4 genera like indifferent. The nun moth defoliated mainly coniferous forests (almost 90 % of all recorded outbreaks with known data about host trees) in the Czech Republic. Forests with mixture of coniferous and deciduous trees were defoliated nine times less frequent, and only insignificant portion were recorded in clearly deciduous forests. Although wide host range, the nun moth has defoliated predominantly spruce forests (almost 70 %). Mixed coniferous (with mixture of spruce, pine, larch, fir) forests were attacked three times less frequently then the spruce forests. Pine and larch forests were defoliated in low range. Defoliations were sorted also according the intensity. Spatial distribution of the recorded outbreaks was displayed in maps.
