This paper is a review of fundamental information on bark beetles and their interactions with several predisposing factors (air pollution, drought/temperature interactions, windthrows, management activities) that are thought to contribute to the outbreaks in the High Tatra Mountains. The findings of many research projects indicate that the impact of air pollution on bark beetle populations is indirect and complex and that the disturbances in the physiology and natural resistance of trees may be of crucial importance to bark beetle population dynamics. An active forest protection approach is needed to be applied to the secondary Norway spruce forests affected in the past by human activity. Bark beetle populations in natural and near-natural forests (mainly in the upper montane zone) are regulated by natural mechanisms; bark beetles are therefore a natural factor contributing to forest development, including the transition of future generations of spruce.

We carried out an experiment with using the entomopathogenic fungus Beauveria bassiana (Bals.) Vuill. for sanitation of active infested trees. We used 15 active infested trees from which 5 stems were treated with an insecticide, 5 were treated with solution of the tested entomopathogenic fungus and 5 were left as control. The used insecticide was pyretroid Fury 10 EW. We used a biopreparation based on the entomopathogenic fungus B. bassiana in form of wettable powder. The material was diluted. The suspension contained 107spores of the tested entomopathogenic fungus in 1 ml. The suspension was applied across the whole stem surface. We succeeded to infect about 28.75% of Ips typographus L. individuals in the treated stems. The number of live individuals was comparable with the variant using the insecticide.

Using GIS techniques, spruce bark beetle Ips typographus (L.) damage was analysed against distance from the edge of small spruce stands with strict protection regime; for reference damage nearby managed spruce stands was used. Mean volume of spruce timber, harvested with sanitary fellings was significantly higher near spruce stands with strict conservation status (14.7 ±2.1 to 17.0 ±3.8 m3/ha) than in the vicinity of managed control sites (9.9 ±0.4 to 11.5 ±0.8 m3/ha). Under endemic spruce bark beetle population levels strict conservation regime in small areas (forest woodland key habitats of average 3.7 ha size) was found to be Ips typographus hazard for adjacent spruce forests up to 450 m distance.

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.

Bark beetle outbreaks and tree mortality patterns should be better understood to control outbreak impacts. We investigated landscape-level patterns of Norway spruce mortality caused by Ips typographus outbreaks across three periods from 1999–2012 in Tatra National Park (Poland) using high-resolution aerial orthophotos and satellite imagery. Shifts in tree mortality related to elevation, slope, and solar equinox radiation were analyzed with ANOVAs (Tukey's HSD tests). Boosted regression trees were employed to assess the forecasting effectiveness of these variables related to mortality period. Spruce mortality severity increased significantly across time in both managed and unmanaged forests. Management activities did not effectively reduce spruce mortality severity. Mortality severity increased significantly at higher elevations over time, while slope and radiation trends varied. Elevation and radiation were the best forecasters of mortality period, exhibiting moderate predictive ability. Beetle-induced spruce mortality increased significantly in Tatra National Park from 1999–2012, particularly at high elevations. Management strategies aimed at minimizing spruce mortality have been ineffective.

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.

From among 392 Picea abies trees growing at the height of 700-800 m above the sea level in the Beskid Sądecki mountain range of the Carpathians (49o35’ N, 19o31’ E, southern Poland), infested by cambio- and xylophagous insects, 110 (28.1%) were also attacked by Ips amitinus (Eichh.). This bark beetle infested most willingly the weakened standing trees of age classes III-V (i.e. 41-100 years old) as well as trees recently overthrown, broken, and felled. It was most abundant in the middle part of the stem where the bark was 2-3 mm thick, infesting 38.4% of its length on the average. On a single tree I. amitinus always occurred in associations of cambio- and xylophagous insects composed of 2-12 species. There was only one generation of I. amitinus in the year, composed of the main brood and the sister brood. Its life-cycle is presented against a background of phenology of forest plants. There were three larval instars. Dimensions of all developmental stages and individual components of brood galleries are also given. I. amitinus plays an important role in killing weakened P. abies trees. The trap trees commonly used against Ips typographus turned out to be very effective also in the control of I. amitinus.

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.
