The occurance of two insect pests, Xyleborus dispar (Col., Scolytidae) - the broadleaved pinhole borer - and Dasyneura abietiperda (Dipt., Cecidomyiidae) - a spruce gall midge - in parts of Austria was worth mentioning. Xyleborus dispar, well known in horticulture and orchards, infested young deciduous tree afforestations in Lower Austria (Waldviertel) and caused severe damage there. Dasyneura abietiperda occurred in old spruce stands as well as in urban gardens on hetches and on individual plants in Carynthia and Lower Austria. Apart from brief information about the biology of the insects and the kind of damage, some recommendations for control are given.
