Sažetak
Two invasive organism Dryocosmus kuriphilus and Cryphonectria parasitica are serios threat to chestnut stands, chestnut trees and the quality of the production of fruit. The interaction of the fungus C. parasitica and chestnut gall wasp D. kuriphilus and the role of other fungi on the necrotic gall wasp in chestnut stands were investigated during the 2012, 2013 and 2014 years. The study was conducted at 7 sites of Croatia: Medvednica, Ozalj, Samobor, Koprivnica, Lovran, Petrinja and Pokupsko where the 30 branches infected with wasp galls were colected randomly per site. On tree selected sites Samobor, Koprivnica and Pokupsko, three tres per site were felled to take the samples for additionall research in 2014 year. Branches were analysed for the presence of chestnut blight and necrotic gall wasp in the trees crown. From necrotic gall wasp the fungi were isolated and determinated using standard phytopathological and molecular methods. 10 gall wasp per site were randomly collected to investigated the presence of the fungi on D. kuriphilus larve. Chestnut fruit were collected on the localities: Medvednica, Samobor and Petrinja. Chestnut fruit were exemined for the presence of the fungi. From necrotic gall wasp the fungi C. parasitica, Gnomoniopsis sp., Colletotrichium acutata, Botryosphaera dothidea, Cytospora sp., Diaporthe eres, Botrytis cinerea, Trichothecium roseum, Trichoderma viride, Alternaria alternata, Penicillium sp. and Fusarium sp. were isolated. On chestnut fruit were determinated following fungi: Aspergillus niger, Aspergillus flavus, Gnomoniopsis sp., Colletotrichum acutata, Botryosphaeria dothidea, Ciboria batschiana, Alternaria alternata, Diaporte eres, Botrytis cinerea, Trichothecium roseum, Trichoderma viride, Penicillium sp., Fusarium sp. On the remains of dead larvae D. kuriphilus the fungi: Alternaria alternata, Botrytis cinerea, Fusarium sp, Penicillium spp were detected. The analysis of dry twigs above gall wasp show that thay were without symptoms of fungi infections and the reason of their drying were physiological conditions. On the chestnut tree crowns infected with D. kuriphilus the diversity of fungi and mutual presence of several types of fungi on gall wasp, larvae of wasp gall and chestnut fruit were observed.
