20.500.12556/DiRROS-17268 Infestation intensity by the invasive oak lace bug, Corythucha arcuata (Say) in mixed and pure oak stands There has been accumulating evidence for effects of tree species composition on herbivory with many examples of lower damage by specialist feeders in tree species rich forests. In a joint study in five Central and Southeastern European countries, we studied the effect of tree species richness on infestation intensity of the oak lace bug, Corythucha arcuata (Say) (Heteroptera, Tingidae), an invasive pest on oak trees that has spread rapidly across the Balkan Peninsula and Central Europe. Intensity of infestation by C. arcuata on oaks was assessed on three or four study plots with high (pure stands) and three or four plots with low percentage of oak (mixed stands) in each country. Ordinal regression analysis showed that intensity of infestation of trees by C. arcuata differed between countries; no significant effect of stand type (mixed or pure) on infestation levels was detected. When analysing the percentage of trees in the highest infestation class, stand type had a significant effect with more intensive infestation in pure stands. We conclude that mixed stands will not prevent severe infestation but may help mitigating the impact of established C. arcuata populations. associational resistance Corythucha arcuata diversity host tree concentration invasive forest pest asociacijska odpornost Corythucha arcuata pestrost koncentracija gostiteljskih dreves invazivni gozdni škodljivci varstvo gozdov entomologija true false true Angleški jezik Slovenski jezik Neznano 2023-11-14 09:32:34 2023-11-14 09:32:35 2024-01-16 03:40:55 0000-00-00 00:00:00 2024 0 0 Nasl. z nasl. zaslona; Opis vira z dne 14. 11. 2023; str. 26-33 iss. 1 Vol. 148 2024 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2023-01-01 630*14 1439-0418 10.1111/jen.13205 171986947 https://onlinelibrary.wiley.com/doi/10.1111/jen.13205 1 fc614b29-82bf-11ee-9ccb-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=23450 RAZ_Hoch_Gernot_2024.pdf RAZ_Hoch_Gernot_2024.pdf 1 9F391125A35BCAD6C33DF217A8DCC4B8 7994884739b8306aaddef974830cc035b09369c78d07d05b4f5ab643a27b000d b76a7fb9-b384-11ee-b0d4-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=24148 Gozdarski inštitut Slovenije 0 0 0
