A distinct black leafspot with fungal growth was found on Platanus orientalis ‘Digitata’ (cut-leaf oriental plane tree) in northern Sydney, New South Wales, Australia, February 2019. Morphological characteristics, internal transcribed spacer sequencing and phylogenetic analysis of the associated fungus identified it as Pseudocercospora platanigena (= Stigmina platani). This pathogen has previou...

Crown shapes of common European urban tree species differ from to and are modified by the age a its local environment. A tree’s crown shape has great influence on volume thus ecosystem service provision such as shade area or density. We used data 3852 individuals eight German cities 528 trees for Acer platanoides, pseudoplatanus, Aesculus hippocastanum, Fraxinus excelsior, Platanus × acerifolia...

The sycamore lace bug, Corythucha ciliata (Say) (Hemiptera: Tingidae), is an important invasive exotic pest of Platanus (Proteales: Platanaceae) trees in China. The objective of this study was to determine the effects of temperature on C. ciliata in the laboratory so that forecasting models based on heat accumulation units could be developed for the pest. Development and fecundity of C. ciliata...
