Sažetak

Sweet chestnut (Castanea sativa) is a species of forest trees which has in the last 50 years experienced considerable and strong attacks from biotic factors in Europe. Primarily this applies to chestnut blight (Cryphonectria parasitica). Chestnut blight has caused great harm to stands of sweet chestnut and diminished the economic importance of this species. A new pest which threatens stands of sweet chestnut is the oriental chestnut gall wasp (Dryocosmus kuriphilus), which appeared in Europe for the first time in 2002., and in Croatia was first recorded in 2010. Interconnection between these two biotic factors and new possibility for growing intensity of chestnut blight caused by the attack of oriental chestnut gall wasp was investigated by Prospero and Forster in Switzerland, 2011. Their research revealed that the possible new entry points of chestnut blight spores are abandoned galls of oriental chestnut gall wasp, which the fungus can saprophyticly populate and can lead to expansion on adjacent branches and formation of cankers. In view of this new information research is necessary in order to determine whether there ise a danger of spreading of this type of infection in stands of sweet chestnut in Croatia.
