Abstract

Prikazujemo sedem vrst metuljev, ki obžirajo hrastove liste: gobar (Lymantria dispar), zeleni hrastov zavijač (Tortrix viridana), mali zimski pedic (Operophthera brumata), veliki zimski pedic (Erannis defoliaria), hrastov sprevodni prelec (Thaumetopoea processionea), zlatoritka (Euproctis chrysorrhoea) in prstaničar (Malacosoma neustria). L. dispar in T. viridana sta se v submediteranskem in predpanonskem območju Slovenije pojavljala večkrat v močnejših gradacijah in povzročala škode. Naslednje dve vrsti pri nas povzročata manjše golobrste predvsem v naravnih sestojih doba v Prekmurju in Krakovskem gozdu ter v sestojih termofilnih hrastov v primorskem območju. T. processionea, E. chrysorrhoea ter M. neustria sporadično povzročajo poškodbe listja hrastov. Ugotavljajo, da se metulji defoliatorji pojavljajo v evropskih gozdovih vse pogosteje in začenjajo ponovno povzročati velike škode.Tudi pri nas ugotavljamo v zadnjih letih ponavljajoče se golobrste v hrastovih sestojih. Na kratko je prikazana morfologija, bionomija, opis poškodb, morebitne zamenjave, gostitelji, najpomembnejši naravni sovražniki inza nekatere omenjene vrste tudi vzroki za nastanek in nadaljevanje gradacij ter ogroženost sestojev.

Secondary title: Oaks - Quercus spp.
Secondary abstract: In the present contribution seven species of butterflies on oaks (Quercus spp.) are presented: gypsy moath (Lymantria dispar), European oak leaf roller (Tortrix viridana), winter moth (Operophthera brumata), mottled umber moth (Erannis defoliaria), oak processionary moth (Thaumetopoea processionea), browntail moth (Euproctis chrysorrhoea) and lackey moth (Malacosoma neustria).L. dispar and T. viridana have appeared several times in the sub-mediterranean and sub-pannonic areas of Slovenia and have caused damage. The next two species cause less significant defoliation mostly in natural pedunculate oak (Quercus robur) stands in Prekmurje and in the Krakovo forest as well as in thermophyllic oak stands in the coastal region. T. processionea, E. chrysorrhoea and M. neustria cause damage on oaks sporadically. Researchers state that butterflies which defoliate forests are appearing more frequently in Europe and are starting to cause extensive damagein forests again. Recently, in Slovenia the situation in oaks forests isthe same. A short description of the insects' morphology, bionomy, a description of damage, possible misidentifications, hosts, their most important natural enemies, causes of beginning or continuation of their outbreaks and their threat to forests are given.
