Infestation of Norway spruce seedlings by Cryphalus asperatus: New threat for planting of forests?
نویسندگان
چکیده
Cryphalus asperatus (Coleoptera: Curculionidae, Scolytinae) is described as an exceptional but important secondary pest of Norway spruce seedlings. Of the 10 000 seedlings transported to one location in Ore Mountains, Central Europe 2020, total 1 500 were killed by C. asperatus. The infestation and death probably resulted part from substantial local increase abundance after sanitation felling many Ips typographus-infested otherwise damaged trees; felled trees provided branches suitable for feeding. In addition, stressed multi-hour transportation (probably drought) forest nursery.

متن کاملPervasive Growth Reduction in Norway Spruce Forests following Wind Disturbance
BACKGROUND In recent decades the frequency and severity of natural disturbances by e.g., strong winds and insect outbreaks has increased considerably in many forest ecosystems around the world. Future climate change is expected to further intensify disturbance regimes, which makes addressing disturbances in ecosystem management a top priority. As a prerequisite a broader understanding of distur...
متن کاملAccumulation of ammonium in Norway spruce (Picea abies) seedlings measured by in vivo 14N-NMR.
(14)N-NMR and (31)P-NMR have been used to monitor the in vivo pH in roots, stems, and needles from seedlings of Norway spruce, a typical ammonium-tolerant plant. The vacuolar and cytoplasmic pH measured by (31)P-NMR was found to be c. pH 4.8 and 7.0, respectively, with no significant difference between plants growing with ammonium or nitrate as the N-source. The (1)H-coupled (14) NH 4+ resonanc...
