Saproxylic Beetles in Standing Dead Wood Density in Relation to Substrate Sun-exposure and Diameter
Species-specific densities of saproxylic beetles in cut 4-m high, medium to large diameter stumps of spruce, birch, aspen and oak were monitored for 7 years after cutting, by trapping emergingExpand

Cut high stumps of spruce, birch, aspen and oak as breeding substrates for saproxylic beetles
Abstract Cut, 4 m high, medium to large-diameter stumps of spruce, birch, aspen and oak were monitored for 7 years as breeding substrates for saproxylic beetles, by trapping emerging insects withinExpand

Is eradication of the pinewood nematode (Bursaphelenchus xylophilus) likely? An evaluation of current contingency plans.
The pinewood nematode (PWN) is one of the worst tree-killing exotic pests in East-Asian countries. The first European record of establishment in Portugal in 1999 triggered extensive surveys andExpand

Ecological effects and management aspects of an exotic tree species : the case of lodgepole pine in Sweden
The North American tree Pinus contorta var, latifolia was experimentally introduced in Sweden already in the 1920s, and has been used in Swedish forestry on a large scale since the 1970s. These plaExpand

Attacks by Ips typographus and Pityogenes chalcographus on Windthrown Spruces (Picea abies) During the Two Years Following a Storm Felling
Attacks by Ips typographus and Pityogenes chalcographus during the first 2 yrs after a storm were studied on 1848 windthrown spruces (Picea abies) in southern Sweden. In the first and second summer,Expand

Attraction of scolytids and associated beetles by different absolute amounts and proportions of α-pinene and ethanol
The attraction of bark and ambrosia beetles as well as associated beetles to α-pinene and ethanol was studied in field experiments with flight barrier traps. α-Pinene and ethanol were releasedExpand

Modelling the potential impact of global warming on Ips typographus voltinism and reproductive diapause
The Eurasian spruce bark beetle, Ips typographus, is one of the major forest insect pests in Europe, capable of mass-attacking and killing mature Norway spruce trees. The initiation and developmentExpand

Recapture of marked spruce bark beetles (Ips typographus) in pheromone traps using area-wide mass trapping
Mark–release–recapture experiments were performed with Ipstypographus (L.) populations to estimate recapture rates (number recaptured/number released) in pheromone traps. The recapture rate of barkExpand
