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.

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.

Trypodendron laeve has a disjunctive distribution and was unknown until recently in most of Europe, where it is now considered by some sources to be an alien pest. The abundance of all four Trypodendron species in Europe (T. laeve, lineatum, domesticum, and signatum) was monitored with traps containing the aggregation pheromone lineatin, which attracts all four species, in 70- to 100-year-old Norway spruce stands in 10 study areas (seven in the Czech Republic and three in Poland). Pheromone-baited, black, window-slot traps (Theysohn, Germany) were deployed (1 to 5 per site) from mid-March/early-April to late-May/early-June. Three Trypodendron species were captured (20,040 beetles). T. lineatum was the most abundant (n = 16,922), followed by T. laeve (n = 2,686) and T. domesticum L.) (n = 432); T. signatum was not detected. T. laeve was detected in three of seven study areas in the Czech Republic over the 3 years of monitoring. Although T. laeve had been detected in Poland during preliminary monitoring in 1988, it was not detected in the three study areas in Poland in the current study. The abundances of T. laeve males and females did not significantly differ in the Czech Republic. The abundance of T. lineatum was correlated with the abundance of T. laeve in the same traps. Although T. laeve has an extensive distribution, its abundance is generally low. Because the species is widely distributed in Europe, there is no practical reason to consider it alien pest in this region.

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.

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.

This study concerns a new neogregarine parasitic in the great spruce bark beetle Dendroctonus micans (Kugelann) (Curculionidae, Scolytinae). The rate of infection was high, reaching 27.3%. There was no difference in the rate of infection of male and female beetles. The life-cycle stages of the pathogen were described by light and electron microscopy. Each gametocyst of the neogregarine included 8–16 actinocephalid oocysts measuring 11.19 ± 0.42 × 4.99 ± 0.25 μm. The described pathogen has the typical characteristics of members of the genus Menzbieria within the order Neogregarinida and it was identified as Menzbieria chalcographi. This is the first record of an infection of D. micans by M. chalcographi. Possibly, this pathogen could be useful for the biological control of this destructive bark beetle.

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.

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.

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.

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.

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.
