Chapter
This chapter describes the impact of some nonbiotic factors on forest health in Europe during the past decades. Storms, floods, and fires, as well as anthropogenic factors, were taken into consideration as primary disturbances predisposing trees to biotic damage. Data and information on the main harmful factors in a few countries obtained since 195...

The presence of Lepturalia nigripes (DE GEER) has been confirmed after more than 80 years in Poland. One specimen of this rare longhorn beetle was collected in the range Grzędy (Biebrza National Park, NE Poland) in a downy birch (Betula pubescens EHRH.) forest affected by fire. Distribution, biology and habitat requirements of L. nigripes are brief...

This paper presents data on 23 beetle species recorded for the first time from the Białowieża Forest (Polish part), and among them two species new for the fauna of Poland. All the beetles were collected using multifunnel (Lindgren) traps, placed in the the selected sites of the study area in 2018. Collected species belong to 13 families: Carabidae...

Open habitats are disappearing from European forests. This is mainly due to various management-related practices, such as afforestation and the maintenance of closed canopy plantation forests. Open forests are also declining as a result of the abandonment of traditional forest use practices and natural succession. The effects of the establishment a...

Common mistletoe is increasingly mentioned as contributing not only to the decline of deciduous trees at roadside and in city parks, but to conifers in stands. The presence of Viscum in fir stands has been known for many years, but since 2015 has also been the cause of damage to pine. In 2019, mistletoe was observed on 77.5 thousand hectares of Sco...
Article
The paper presents new data on the occurrence of 69 beetle species collected in 2017 in the Białowieża Forest, NE Poland. The list contains representatives of 27 families: Anthribidae, Bostrichidae, Ciidae, Cleridae, Coccinellidae, Corylophidae, Cryptophagidae, Curculionidae, Dasytidae, Elateridae, Endomychidae, Eucnemidae, Histeridae, Laemophloeid...
Article
Organisms dependent on dead wood (i.e., saproxylic) are some of the most threatened by changes in the forest environment. Aside from anthropogenic disturbances resulting in forest fragmentation and a decrease in dead wood, the expansion of homogenous closed-canopy forests due to successional changes is identified as the main threat for many saproxy...

The paper presents the changes in the Scots pine forest conditions in Poland in 2015-2018, with a special focus on the increasing threat from "new" (Ips acuminatus, Viscum album ssp. austriacum) and "old" (Diplodia sapinea, Phaenops cyanea, Monochamus galloprovincialis, Lymantria monacha, Panolis flammea, Dendrolimus pini, etc.) pests as an effect...

Full-text available
Root-feeding Melolonthinae larvae are a forest pest species in Europe that can exert serious damage. In Poland, they are classified as the most dangerous pest on land dedicated to afforestation and the most serious threat to natural regeneration in the stands. This study was performed in three forest districts in east Poland (Lubartów, Marcule, and...

New data on the distribution, biology and ecology of the longhorn beetles occurring in southern and eastern regions of Kazakhstan are presented together with a list of 78 species that were collected during two entomological expeditions conducted in May and June 2017. New localities of some rare taxa endemic to this region of Asia, such as Psilotars...
Article
Monochamus sartor sartor from Central European mountain ranges and M. s. urussovii from the Eurasian boreal zone are subspecies whose taxonomic statuses have been questioned. This sawyer beetle is a natural element of spruce forests but is considered to be a timber pest in spruce plantations. In this study, different sets of data (morphology, genet...

A Fibroporia gossypium (Speg.) Parmasto fruit-body was found on a Norway spruce [Picea abies (L.) Karst.] stump in the northeast of Poland (Waliły forest district). The mycelium from wood samples was sequenced (KF725876), identified and used to examine: (i) linear growth of the mycelium on malt-extract medium and (ii) the decay of spruce wood sampl...

Spruce stumps located in 10 stands, representing the northern and southern range of distribution of Norway spruce in Poland and growing on post agricultural lands, were artifi cially inoculated with two registered Phlebiopsis gigantea preparations against Heterobasidion annosum s.l. One year later a total of 240 wood cores were taken from three ran...

The paper presents the results of our studies on the preferences of the flower chafer, Protaetia speciosissima (Scopoli, 1786). The studies were carried out in 2009-2010 in the Forest Districts of Hajnówka, Krotoszyn, Łochów, Pińczów, and Puławy, located in various regions of Poland. Barrier traps consisting of a Moericke's trap and a Malaise's tra...

Number of Melolontha grubs in forest soils reforested with Scots pine (Lubartów A, LA, Lubartow B, LB) and those in post agricultural soils afforested with this species (Swierczyna, SW) were assessed before (autumn 2011, spring 2012) and one year after (2013) planting. At the same time, mortality of seedlings was evaluated on both study sites. Pine...

In the study, the influence of remises (forest plots of high biodiversity) on abundance of Carabidae assem− blages is presented. Results were analysed using ecological indices as well as bioindicators. It was obtain that the development of Carabidae is going faster in remises than on control plots (forest around remises). The forest species and lar...

Effectiveness of protection of the horse-chestnut against the horse chestnut leaf-miner Cameraria ohridella was evaluated using diflubenzuron and chlotianidine. Spraying of trees with water suspension of Dimilin 25 WP (0.05%) and Dimilin 480 SC (0.025%) during the first swarm of butterflies was found to protect horse-chestnuts effectively against d...

A three-year researches were conducted to assess the similarity of Carabidae communities on 3 plots differentiated in age, planned in "remises" of complex-centre forest protection method which are the patches of 5-12 ares with fell and broadleaved trees and shrubs, and in Scots pine stands as control. In remises as well as in control stand the most...
