    Opis:
    W 2014 roku prowadzono badania nad fauną chrząszczy saproksylicznych, w tym korników w siedlisku borów sosnowych Puszczy Kampinoskiej. Badania objęły trzy powierzchnie reprezentujące dojrzałe drzewostany ze starodrzewem sosnowym w obszarach ochrony ścisłej Sieraków i Kaliszki. Chrząszcze były odławiane na każdej powierzchni w okresie IV – VII za pomocą pułapek ekranowych IBL-2, przegrodowych IBL-5 oraz żółtych misek Moerickego. W trakcie badań odłowiono 30 gatunków korników, z czego aż 24 nie było wcześniej wykazywanych z obszaru Kampinoskiego Parku Narodowego. Dominującymi gatunkami były Xyleborinus saxesenii, Hylastes opacus i Trypodendron lineatum. Większość, bo aż 19 odłowionych gatunków biotycznie związanych jest z drzewami iglastymi.
    Bark beetles (Coleoptera, Curculionidae, Scolytinae) of the pine forest of Kampinos National Park. The research on saproxylic beetles, including bark beetles, inhabiting pine forests in Kampinos forest was conducted in the year 2014. It covered three sites representing mature pine stands located in the strict protection areas Sieraków and Kaliszki. Beetles were trapped in IBL-2 screen traps, IBL-5 partition traps and Moerick’s on each site from April till July. 30 species of bark beetles were trapped 24 of which were not previously noted in Kampinos National Park. Xyleborinus saxesenii, Hylastes opacus and Trypodendron lineatum were the dominating species. 19 of the noted species are biotically connected to conifers.

    Korniki: drzewotocz japoński - Xylosandrus germanus (Bldf.), drwalniczek – Xyleborinus attenuatus (Bldf.), drwalnik – Trypodendron laeve i Gnathotrichus materiarius (Fitch) Egg. (Coleoptera, Curculionidae, Scolytinae) to obce gatunki w faunie Polski. Drzewotocz japoński Xylosandrus germanus jest też gatunkiem inwazyjnym, który znany jest z 11 stanowisk w prawie całym kraju. Liczebność tego gatunku na znanych stanowiskach szybko wzrasta. Drzewotocz jest ekstremalnym polifagiem i rozwija się w drewnie ponad 200 gatunków drzew i krzewów. W Europie zasiedla zwykle martwe drzewa. Jednak może być bardzo niebezpieczny, ponieważ atakuje także zdrowe drzewa, więc może stać się poważnym szkodnikiem w Środkowej Europie. W Polsce najczęściej spotykany jest w zdrowym drewnie buka, dębu, jesionu, olszy, wiązu i sosny, ale prawdopodobnie zasiedla inne drzewa. Pozostałe gatunki mają mniejsze znaczenie.
    Alien species of bark beetles (Coleoptera, Curculionidae, Scolytinae) in the Polish fauna and potential risks to forest stands. Bark beetles: Xylosandrus germanus (Bldf.), Xyleborinus attenuatus (Bldf.), Trypodendron laeve and Gnathotrichus materiarius (Fitch) Egg. (Coleoptera, Curculionidae, Scolytinae) are alien species in Polish fauna. Xylosandrus germanus is also invasive species, which is known from the eleven localities most of the country. The number this species on well-known localities is increasing rapidly. X. germanus is extremely polyphagous and develops in the wood over 200 species of trees and shrubs. In Europe it usually infests dead trees. However it is considered as a very dangerous because it attacks also healthy trees, so it may become a serious pest in Central Europe. In Poland, the most common in healthy wood of beech, oak, ash, alder, elm and pine trees, but probably inhabits a diff erent trees. Other species are less important.

    Opis:
    In 2013–2014, a set of 30 pheromone traps baited with synthetic lures attracting I. duplicatus (Duplodor – 15 traps) and I. cembrae (Cembrodor – 15 traps) was installed in 6 altitudinal transects (1000–1400 m a.s.l., every 100 m of elevation) in the eastern, central and western part of the Tatra National Park (TPN) in Poland and operated during the entire growing season. The main aim of the survey was to check if and to what vertical extent these two species of bark beetles, not yet recorded, are presently distributed in TPN. Collected insects, including non-target Scolytinae and Cerambycidae, were determined. Overall 1896 Scolytid bark beetles belonging to 13 species, all occurring in the whole elevation range, were collected. I. duplicatus (28 specimens in total) was collected in the whole elevation profile, similarly as I. cembrae (718 specimens in total). Among Cerambycidae (282 individuals) belonging to 19 species, Rhagium inquisitor and Pidonia lurida, found on all elevations, were the most abundant; 8 species were collected on the highest locality. Pogonocherus decoratus was found for the first time in the Tatra. Results indicate the upward spreading of the studied insects as a possible effect of climate change and the resulting environmental conditions favourable for those organisms.

    Opis:
    The six-toothed bark beetle (Ips sexdentatus) is known to be associated with ophiostomatoid fungi. However, very little is known about these fungi in Poland. The aim of this study was: 1) to identify fungi of Ophiostoma s. lato carried by this bark beetle and 2) to test the pathogenicity of several commonly occurring fungi. Isolations were carried out from the beetles and their galleries at three sites in Poland. Samples yielded a total 3162 cultures, which included 10 species of Ophiostoma s. lato. The most frequently encountered fungal associates of I. sexdentatus were L. cf. truncatum, O. brunneo-ciliatum and O. ips. Ophiostoma cf. rectangulosporium, O. cf. abietinum, O. quercus and O. floccosum appeared to be also specifically associated with I. sexdentatus. Leptographium cf. truncatum and O. minus were most virulent and can be consideredas serious pine pathogens.

    Opis:
    This study dealt with the species distribution and frequency of ophiostomatoid fungi associated with the bark beetle Ips typographus on Norway spruce and Scots pine in north-eastern Poland. At all locations high spruce bark beetle damage has occurred in 2002-2003. Fungi were isolated from beetles and from brood systems of trees infested by the spruce bark beetle. The ophiostomatoid fungi were represented by 13 species. A similar spectrum of ophiostomatoid fungi as that recorded from Picea abies was associated with I. typographus on Pinus sylvestris trees. The most frequent ophiostomatoid species isolated from beetles, phloem and sapwood of Norway spruce were O. bicolor and O. penicillatum. The frequency of occurrence of ophiostomatoid fungi varied significantly among the examined locations. O. bicolor was the most frequently found species on Scots pine infested by I. typographus. The potential role of ophiostomatoid fungi in the epidemiology of I. typographus is discussed. Additionally, we also recorded how the ophiostomatoid fungi associated with spruce bark beetle could grow into phloem and sapwood of Pinus sylvestris trees.

    Opis:
    Ophiostomatoid fungi are known to be associated with Tomicus spp. on Pinus sylvestris. However, very little is known about the fungi present in the pine shoots damaged by these insects. The aim of this study was to survey species of Ophiostoma s.l. associated with fallen shoots of Scots pine pruned by Tomicus spp. in Poland. The study was conducted in four pure Scots pine stands in southern and south-western part of the country. Fungi were identified based on morphology and DNA sequence comparison for two gene (the ITS rDNA region and ß–tubulin). In total, 64 isolates obtained, represent seven species of ophiostomatoid fungi, including their asexual states of the genera. Two of them, Ophiostoma sp. 1 and Sporothrix sp. 1 probably represent new taxa. All species were found at very low frequencies. Among them, Ophiostoma minus, Ophiostoma sp. 1 and Sporothrix sp. 1 were the most frequently isolated, with a frequency of 2.0%. Occasionally, isolated species were: Leptographium piriforme, Ophiostoma canum, O. floccosum and Grosmannia cucullata-like. Association of species of Ophiostoma s.l. with Tomicus spp. and the taxonomic status of two new species are discussed.
    Grzyby należące do grupy gatunków w przeszłości zaliczanych do rodzaju Ophiostoma s.l. są znane ze współżycia z owadami z rodzaju Tomicus żerującymi na sośnie zwyczajnej Pinus sylvestris L. Jednakże bardzo mało wiemy o grzybach występujących w pędach sosny, uszkodzonych przez te owady. Celem badań było poznanie składu gatunkowego i frekwencji występowania grzybów z tej grupy związanych z pędami sosny zwyczajnej uszkodzonymi przez żer uzupełniający cetyńców. Badania przeprowadzono w latach 2007-2008 w czterech drzewostanach sosnowych zlokalizowanych w różnych częściach Polski. Grzyby były identyfikowane na podstawie cech morfologicznych, a wybrane, reprezentatywne szczepy grzybów poddano także amplifikacji i sekwencjonowaniu fragmentów ITS1, 5.8S, ITS2 oraz fragmentów genu ß-tubuliny. Ogółem, z pędów uszkodzonych przez cetyńce, otrzymano 64 izolaty grzybów reprezentujące siedem gatunków grzybów należących do Ophiostoma s.l. Dwa z nich, Ophiostoma sp. 1 i Sporothrix sp. 1 prawdopodobnie reprezentują taksony nowe dla nauki. Niepewny pozostaje również status taksonomiczny izolatu zaklasyfikowanego jako Grosmannia cucullata-like. Wszystkie stwierdzone gatunki charakteryzowały się niską częstością występowania. Wśród nich, Ophiostoma minus, Ophiostoma sp. 1 i Sporothrix sp. 1 były izolowane z 2.0% pędów. Pozostałe gatunki grzybów (Leptographium piriforme, Ophiostoma canum, O. floccosum i Grosmannia cucullata-like) zasiedlały pędy sosny sporadycznie. Wśród zidentyfikowanych grzybów O. floccosum, Ophiostoma sp. 1 i Sporothrix sp. 1 zostały stwierdzone w Polsce po raz pierwszy.

    Opis:
    In the years 2005– 2006, in the Karkonoski National Park there were conducted observations on infestation of spruce trees by bark beetles (Col., Curculionidae, Scolytinae). Data on bark beetle species composition and frequency of occurrence of individual species were collected. The data on development phenology of the small spruce bark beetle Ips amitinus in the upper subalpine spruce forest sites (1000– 1250 m a.s.l.) indicated higher frequency of occurrence of this species (26.3%) when compared to the European spruce bark beetle Ips typographus. The study included analyses of population size, density, fecundity and mortality of I. amitinus. The rate of development in I. amitinus in the Karkonosze Mts. is similar to that observed in the Alps. The number of laid eggs observed was low and the reproduction success was very high at minimal mortality. Establishment of feeding galleries and egg laying lasted several weeks and 1/3 of feeding galleries were found in the second series of trap trees.

    Opis:
    Ips duplicatus adults were sampled with pheromone-baited black window-slot traps (Theysohn) in 70- to 100-yearold Norway spruce (Picea abies) stands between 280 and 650 m a.s.l. in the eastern Czech Republic and southern Poland during 2000– 2010. Sets of 5–12 traps were placed about 20 m from the edge of the infested forest. Each trap was baited with a standard synthetic pheromone lure (ID Ecolure), and was setup 1.5–2.0 m above the ground. The objectives were to determine the relationship between the numbers of adults trapped in the overwintered generation and those in the offspring generation. According to data from 135 traps, the numbers of overwintered beetles captured in spring (April–June) were significantly higher than the numbers captured in summer (July–August), but the numbers of offspring beetles captured in summer were significantly correlated with the numbers overwintered beetles captured in spring. The spring captures can be used to estimate the threat caused by I. duplicatus during the whole vegetation season. The traps installed in summer should be used to determine the peaks in the bark beetle flight activity, thus enabling early identification of trees infested by I. duplicatus, especially inside stands.

    Field research was conducted in selected pine−spruce stands of the Oleśnica Śląska Forest District (SW Poland), where in 2004 intensive mortality of trees infested by I. typographus and I. duplicatus was observed. The results show that most I. typographus beetles hibernated under the bark of sample trees (71.2%). Most I. duplicatus beetles hibernated in forest litter and soil (90.5%). In the litter and soil samples, the largest number of hibernating beetles (of both species) were observed in the close neighborhood of tree stems, within the radius of up to l m (96.2% and 94.0% respectively). The estimated number of beetles hibernating in the forest litter and soil under the canopy of a single sample tree was 383 and 61, respectively. In bark samples I. typographus hibernated only as adult (imago).

    Opis:
    In 2010–2012, investigations on Ips typographus populations were carried out in Norway spruce stands recently affected by bark beetle outbreak in the Beskid Żywiecki Mts. in Poland. The aim of the study was to test the usefulness of several traits describing I. typographus populations for evaluation of their actual outbreak tendency. Infestation density, sex ratio, gallery length, progeny number and beetle length were used as the traits. Trait variability was analyzed in relation to infested tree mortality in the current year of observation and outbreak tendency defined by the comparison of data on tree mortality in the current year and that in the year before. The highest infestation density was found in the stands representing the highest tree mortality in the current year and in those characterized by decreasing outbreak tendency. The gallery system with 2 maternal galleries dominated. The sex ratio of attacking beetles inclined towards females (63.8%) and remained stable during 3 years of observations; the highest percentage of females was found in locations being in stabilization/latency outbreak phase. The length of maternal galleries was somewhat negatively affected by infestation density and positively correlated with the number of progeny in the gallery. The average beetle length was 4.800 mm (± 0.293), ranging between 3.718 and 5.817 mm and being the highest in the uppermost class of tree mortality recorded in the current year of observation. The shortest beetles were collected in the stands with increasing outbreak tendency, and slightly longer – in the stands with outbreak stable and decreasing tendencies. None of the traits tested can be selected as a direct indicator for prediction of outbreak tendency in I. typographus populations. Possible reasons of variability in the analyzed traits are discussed. The traits indicate that I. typographus in the study area represent very high reproductive potential, thus the risk of repeated outbreak is very high.

    Opis:
    The strictly protected Swiss stone pine (Pinus cembra) is one of the most valuable elements of Polish dendroflora, naturally distributed only in the Tatra Mts. (S Poland/N Slovakia). In 2008−2009 intense P. cembra dieback was recorded in Slovak part of the mountains, especially in the localities adjacent to the Norway spruce stands affected by bark beetle Ips typographus outbreak. The mortality of individual P. cembra trees was observed in 2012 also in the Polish part, next to the area of the bark beetle outbreak on spruce. In the winter 2017/2018 the survey was carried out in order to assess the intensity of P. cembra dieback and the impact of the bark and wood boring insects on this process. In Suchej Wody Valley, where all P. cembra trees were precisely mapped in 2004−2008, health status of all previously living trees were checked again. In the summer 2018 bark samples from 50 dying or dead standing trees attacked by those insects and distributed over the whole Tatra National Park area were collected in order to define their species composition based on the gallery systems and (if possible) beetles or their fragments. Only 4 out of 439 checked trees (<1%) were recorded as dead. The bark samples were collected mostly from dead trees (88%), and in some cases from dying ones. The presence of insects belonging to 10 taxa (Curculionidae, Scolytinae – 6, Molytinae – 1; Cerambycidae – 2) was detected. Most of them is known as infesting Norway spruce. The most frequently (on the entire tree level) occurring were Cerambycids Tetropium sp. (56%) and Rhagium sp. (36%), as well as I. typographus (52%), contrarily to the species known as living on or preferring P. cembra (I. amitinus, Pissodes pini, Polygraphus sp.). The dieback of Swiss stone pine seems to be a slow process, in which the bark and wood boring insects (I. typographus, I. amitinus, Tetropium sp., Pityogenes chalcographus, Polygraphus sp.) are involved, but rather as secondary factor affecting weakened trees. However, the possible impact of the bark beetle outbreak in neighbouring spruce stands, expressed by high I. typographus frequency, should be also taken in consideration.
