Ips amitinus (Eichh.) and Pityogenes chalcographus (L.) reached the higher frequency of occurrence on sections placed in the open area than in half-shade and on stems felled in the autumn season than in the spring season. Dryocoetes autographus (Ratz.) was markedly profiled on sections in half-shade with the gradual desiccation of phloem. P. chalcographus preferring open areas occurred on branches being accompanied by Cryphalus abietis (Ratz.), which attacked branches located in half-shade. On stems of sections from both autumn and spring felling, one generation of I. amitinus developed, however, on autumn sections, the 2nd generation developed unsuccessfully on the original nutritive material. P. chalcographus completed the development of one generation on stems and branches from autumn felling. On the spring material, the invasion was delayed and a part of wintering larvae did not complete their development.

The region, on the whole, is notable for the domineering coniferous and a great diversity of forests, with Pinus sylvestris L., Pinus sibirica Du Tour, Abies sibirica Ledeb. and Picea obovata Ledeb. being domineering species. The physicogeographical conditions of the region are favourable for reproduction of coleopterous insects in weakened stands on oversaturated soils, in forests exploited with violation of the logging technology, in fire-damaged stands as well as in the locus of the rot diseases. Increased numbers of the dendrophagous insects are observed in timber store-houses, wood processing plants and in sites of transporting timber beyond the region including the countries importing Russian timber, in which a number of coleopterous phytophagans living in the Priketye forests are objects of a forest quarantine. The investigations were conducted in 2001[long dash]2009. The conventional methods of the pathology investigation of the forest were used when the material was being collected: route examination of the forests; analysis of model trees of various conifer species for insect invasion in sample areas in the forests; analysis of the quarantine forest materials. The total volume of the material collected and studied was 2,780 samples of beetles. The article is supplied with an annotated list of 60 species of the coleopterous families Buprestidae, Bostrichidae, Cerambycidae, Curculionidae and Scolytidae feeding on the trunk tissues of the coniferous. The list contains information on their spread in Tomsk Oblast and some original data on the Priketye location and ecology. For the first time, 17 species have been indicated for the region studied: Buprestis octoguttata, Anthaxia quadripunctata, Stephanopachys substriatus, Tragosoma depsarium, Acmaeops marginatus, A. septentrionis, A. smaragdulus, Gnathacmaeops pratensis, Anastrangalis sequensi, Pronocera sibirica, Semanotus undatus, Monochamus saltuarius, Acanthocinus griceus, Pissodes piniphilus, P. harcyniae, Hylastes opacus, Pityogenes irkutensis.

This means a slight decrease of bark beetle damage compared to the year before. However, the record level of 2 million m3 has been exceeded the fifth consecutive year. Due to the massive wind throw from gales early in 2008, bark beetle gradation will remain a topical issue. Seven federal provinces joined the Austrian bark beetle monitoring system consisting of approximately 170 pheromone traps. The flight activity and especially the flight maxi-mum differed considerably.

(Coleoptera: Scolytinae), was studied on Norway Spruce (Picea abies) L. (Karst.) stands in southern Poland. It was found that such materials, originating from windbreaks and windfalls and spread loosely over the forest floor, were more readily infested by P. chalcographus than materials gathered in piles. However, the beetles achieved a significantly higher reproductive efficiency (number of new generation beetles per each parent individual) on branches in piles than on those spread loosely. In piles, the P. chalcographus infestation density, measured as the total number of individuals per square decimetre of bark area, and reproductive efficiency varied, depending on the location of the branches in a pile. The most favourable breeding conditions occurred in the middle layer of a pile. It was also found that at different infestation densities the method and placement of woody debris deposition did not affect the number of beetles that emerged. These results are discussed in the context of using logging residues as natural traps for bark beetles.10aPityogenes chalcographus1 aKacprzyk, Magdalena  uhttps://weevil.myspecies.info/feeding-habits-pityogenes-chalcographus-l-coleoptera-scolytinae-norway-spruce-picea-abies-l-karst-lo01546nas a2200169   4500008004500000020001400045245010200059210006900161260000900230300001200239490000700251520093400258653002601192100001801218700001401236856012601250       2008                        Engldsh    a1437-478100aAssociations between Pityogenes bidentatus and fungi in young managed Scots pine stands in Poland0 aAssociations between Pityogenes bidentatus and fungi in young ma  cJune  a169-1770 v383 aThe association between Pityogenes bidentatus and fungi was studied in young, managed Pinus sylvestris stands in Poland.

Geosmithia sp. 1 species was the dominant species in P. bidentatus galleries with a frequency of occurrence of 57.9%. Hormonema dematioides was the second most abundant fungus in gallery systems (17.1% of wood samples). Two of the isolated Geosmithia species were previously undescribed.

The logs stored in sunny place were less infested, and the infestation density was not related to the section diameter. The frequency and infestation density was lower by 13 and 6.5 times, respectively, on the logs sprayed with lime. In 2006, high (88%) P. chalcographus frequency was found on standing, infested trees next to the place of experiment from 2005. Stored spruce timber can serve as additional breeding material for the pest, but can also be used as trap logs. The consequences of such untypical occurrence for the threat to the surrounding spruce stands are discussed and possible forest protection practices are proposed.10aPityogenes chalcographus1 aGrodzki, Wojciech1 aPlata, Jaroslaw  uhttps://weevil.myspecies.info/stored-spruce-timber-breeding-material-pityogenes-chalcographus-l-col-curculionidae-scolytinae01878nas a2200193   4500008004500000020001400045245012700059210006900186260000900255300001000264490000900274520115500283653002001438653002901458100001901487700002401506700001901530856013501549       2008                        Serbdan    a0350-175200aNatural regeneration of mixed spruce and fir stand (Abieti-Piceetum) damaged by spruce bark beetles in the area of Knezevo0 aNatural regeneration of mixed spruce and fir stand AbietiPiceetu  c2008  a53-640 v20083 aNatural regeneration in a mixed fir and spruce stand (Abieti [long dash] Piceetum) was resea- rched on the areas damaged by spruce bark beetles and reclaimed by clear cutting. The damage occurred in 2003 due to poorly applied forest order.

The degree of regeneration, abundance and the characteristics of fir and spruce young growth were studieddepending on the aspect of the regeneration areas and their sizes. Natural regeneration of firand spruce stands after the reclamation of the damage caused by bark beetles should be adapted to a specific management system, because the differences in fir and spruce bioecological characters require different silvicultural procedures depending on the actual state. By the application of clear cutting in the form of circular areas with eccentric extensions, the conditions of spruce natural regeneration can be improved in the aim of achieving the technical goals of management of mixed fir and spruce forests.10aIps typographus10aPityogenes chalcographus1 aGovedar, Zoran1 aStanivukovic, Zoran1 aZlokapa, Brane  uhttps://weevil.myspecies.info/natural-regeneration-mixed-spruce-and-fir-stand-abieti-piceetum-damaged-spruce-bark-beetles-area-kne01317nas a2200205   4500008004500000020001400045245018900059210006900248260001300317300001000330490000700340520049700347653002000844653002900864100002100893700001900914700002300933700002000956856013500976       2008                        Engldsh    a1815-511100aResearch on the proper usage of the pheromone trap method monitoring and mass trapping of Ips typographus L. and Pityogenes chalcographus L. in the federation of Bosnia and Herzegovina0 aResearch on the proper usage of the pheromone trap method monito  cNovember  a10-110 v443 aThe purpose of this paper is to determine the number of installed synthetic pheromone baited traps for monitoring and mass trapping of 1ps typographus and Pityogenes chalcographus. the types of traps and pheromone dispensers and the propriety of used method on the site (trap position, trap distance of the nearest healthy spruce tree, trap height, etc.) are examined.

(Coleoptera: Scolytinae) causes damage in European coniferous forests, primarily on Picea abies L. Karst., but is also recorded on other native and exotic Pinaceae species. Estimating the adequacy between adult preference and larval performance of this beetle among its host-range, as well as the influence of plant taxonomic relatedness on these parameters, would provide useful information on the beetle's ability to shift onto novel hosts.Choice and no-choice assays were conducted under laboratory conditions. Adult preference and larval performance parameters among two native (Pinus sylvestris L. and Picea abies) and three exotic north American (Pinus contorta Dougl., Picea sitchensis (Bong.) Carr. and Pseudotsuga menziesii Mirbel (Franco)) conifer species were measured.Pityogenes chalcographus exhibited a significant positive relationship between preference and performance. Picea abies was both the preferred and the most suitable host species for larval development. The closest relative, P. sitchensis, was the second best choice in terms of preference and performance. Pseudotsuga menziesii occupied an intermediate position for both beetle preference and performance, and Pinus spp. were the least suitable hosts for beetle development.Adult preference and larval performance ranking among hosts provides little support to the plant taxonomic relatedness hypothesis. Taxonomic relatedness could play a role on the diet breadth, although only at a limited scale, within the genus Picea. At higher taxonomic levels, other factors such as bark thickness might be decisive.10aPityogenes chalcographus1 aBertheau, Coralie1 aSalle, Aurelien1 aRoux-Morabito, Geraldine1 aGarcia, Jacques1 aCertain, Gregoire1 aLieutier, Francois  uhttps://weevil.myspecies.info/preference-performance-relationship-and-influence-plant-relatedness-host-use-pityogenes-chalcographu02195nas a2200205   4500008004100000020002500041245015200066210006900218260000800287300001200295490000700307520138600314653002901700100002201729700003201751700001901783700002301802700002901825856013501854       2012                        eng d  a1286-4560; 1297-966X00aLack of genetic differentiation after host range extension argues for the generalist nature of Pityogenes chalcographus (Curculionidae: Scolytinae)0 aLack of genetic differentiation after host range extension argue  cApr  a313-3230 v693 aThe bark beetle, Pityogenes chalcographus, is one of the main pests in Picea abies stands, and it has also been found on other European Pinaceae species. With massive introductions of North American conifer species into European forests, this insect has extended its host range to exotic Pinaceae species. This study assessed whether a wider host range has influenced the genetic structure of P. chalcographus and has led to host specialization. Insects were collected from two different regions of France, where eight native and exotic conifer species coexist and were analyzed using mitochondrial and nuclear genetic markers. Considerable haplotypic diversity was observed within the regions and within host species from where P. chalcographus populations were collected. No genetic differentiation, especially with respect to host species associations, could be detected. Moreover, no relationship could be established between closely related P. chalcographus haplotypes and taxonomically related conifer species. The capacity of P. chalcographus for host shifting and dispersal may have played a key role in the rapid extension of its host range. These findings are important for pest management in forests and health and phytosanitary measures in the timber trade, especially for risk assessment in mixed coniferous forests including tree species of major economic importance.10aPityogenes chalcographus1 aBertheau, Coralie1 aBankhead-Dronnet, Stephanie1 aMartin, Carine1 aLieutier, Francois1 aRoux-Morabito, Geraldine  uhttps://weevil.myspecies.info/lack-genetic-differentiation-after-host-range-extension-argues-generalist-nature-pityogenes-chalcogr01752nas a2200181   4500008004500000020001400045245011500059210006900174260000900243300001200252490000700264520106400271653002901335100002601364700002301390700002401413856013301437       2008                        Engldsh    a0024-406600aSympatric occurrence of diverged mtDNA lineages of Pityogenes chalcographus (Coleoptera, Scolytinae) in Europe0 aSympatric occurrence of diverged mtDNA lineages of Pityogenes ch  cJune  a331-3400 v943 aDifferentiation among the European populations of the six-toothed spruce bark beetle Pityogenes chalcographus was observed for the first time in the 1970s as mating males from Northern Europe with females from Central Europe led to a significant decline in fecundity. Morphological examination revealed that P. chalcographus can be separated into two European races. Here, we investigated the genetic background of this separation by analysing 39 populations (n = 695), sequencing almost the complete cytochrome oxidase I gene (1543 bp) and applying single-strand conformation polymorphism. Phylogenetic analysis of 58 haplotypes yielded three major clades with a maximum sequence divergence of 2.33%, indicating that the demographic events took place in the late Pleistocene. These results support the hypothesis of allopatric divergence of the mtDNA lineages, which postglacially came into sympatric existence in Europe. However, as a result of partial crossing incompatibility the diverged lineages retained their genetic identity during postglacial times.10aPityogenes chalcographus1 aAvtzis, Dimitrios, N.1 aArthofer, Wolfgang1 aStauffer, Christian  uhttps://weevil.myspecies.info/sympatric-occurrence-diverged-mtdna-lineages-pityogenes-chalcographus-coleoptera-scolytinae-europe01874nas a2200205   4500008004100000020001400041245012600055210006900181260000900250300000900259490000700268520114000275653002901415100001901444700001701463700001701480700001501497700002101512856013501533       2010                        eng d  a0254-538100aPityogenes chalcographus (Coleoptera: Scolytinae) at the southernmost borderline of Norway spruce (Picea abies) in Greece0 aPityogenes chalcographus Coleoptera Scolytinae at the southernmo  c2010  a3-130 v193 aThe six toothed bark beetle, Pityogenes chalcographus L. (Coleoptera: Scolytinae) is a widely distributed pest in Europe, infesting mainly Norway spruce (Picea abies) as well as other conifer species such as Pinus sp., Abies alba, Larix deciduas, L. sibirica and Pseudotsuga douglasii. Even though the distribution of this bark beetle coincides that of its main host tree, P. abies, the occurrence of P. chalcographus has never been recorded in the spruce forest of Elatia-Drama, Northern Greece, which is the southernmost area of the natural, autochthonous distribution of P. abies. In this study we installed five pheromone traps baited with chalcogran dispensers in the forest of Elatia. The total number of bark beetles attracted to these traps exceeded several thousands of individuals. Norway spruce trees growing in the natural forest of Elatia demonstrate low vigor, something that can be attributed to the marginal environmental conditions in concert with the effects of climate change. The combination of these factors inhibits the regular growth of spruce, rendering trees more susceptible to the attack of P. chalcographus.10aPityogenes chalcographus1 aAvtzis, D., N.1 aArthofer, W.1 aStauffer, C.1 aAvtzis, N.1 aWegensteiner, R.  uhttps://weevil.myspecies.info/pityogenes-chalcographus-coleoptera-scolytinae-southernmost-borderline-norway-spruce-picea-abies-gre02209nas a2200193   4500008004100000245009800041210006900139260000900208300001000217490000700227520151800234653002901752100002301781700002601804700002001830700002501850700002401875856011601899       2007                        eng d00aPitfalls in applying mitochondrial markers onto the scolytid species Pityogenes chalcographus0 aPitfalls in applying mitochondrial markers onto the scolytid spe  cJune  a15-190 v453 aPityogenes chalcographus is one of the major pests in Eurasian spruce stands. Crossing experiments performed in the mid-1970s suggested race differentiation, and mtDNA analysis of P. chalcographus gave evidence that today's populations are divided into several clades. The genetic distance between clades favours a model of allopatric origin with a separation about one million years ago while today haplotypes of the major clades exist sympatrically all over Europe. Within the last few years, the use of mtDNA as a sole genetic marker became a matter of critical discussion. It was shown that nuclear copies of mtDNA (numts) led to artefacts in some of the derived genealogies. A long PCR based approach for elimination of potential numt sequences was developed to validate the dataset of P. chalcographus. This method showed that the beetle's genome does not contain numts. Another factor that may influence mitogenomes is the presence of endosymbiotic Wolbachia, which causes alterations in insect reproduction and thus influences the population's mtDNA patterns. While Wolbachia was not found in P. chalcographus in past studies, the use of long and nested PCR, cloning and sequencing of PCR products, and in situ hybridization techniques gave evidence that at least a certain percentage of European populations harbour this intracellular endosymbiont. An influence on the mitochondrial dataset can not be excluded and further research is proposed to estimate the prevalence of Wolbachia in P. chalcographus.10aPityogenes chalcographus1 aArthofer, Wolfgang1 aAvtzis, Dimitrios, N.1 aRiegler, Markus1 aMiller, Wolfgang, J.1 aStauffer, Christian  uhttps://weevil.myspecies.info/pitfalls-applying-mitochondrial-markers-scolytid-species-pityogenes-chalcographus01548nas a2200217   4500008004100000020001400041245011600055210006900171260001400240300001200254490000700266520074900273653002901022100002301051700003201074700002501106700002601131700002201157700002401179856012701203       2007                        eng d  a0022-284400aLessons from a beetle and an ant: coping with taxon-dependent differences in microsatellite development success0 aLessons from a beetle and an ant coping with taxondependent diff  cSeptember  a304-3070 v653 aMicrosatellites are powerful markers often isolated de novo for species yet to be investigated. Enriched genomic libraries are usually used for isolation purposes. We critically evaluate the outcome of an enrichment-based protocol applied to two insect species (the ant Lasius austriacus and the beetle Pityogenes chalcographus) which yielded contrasting numbers of suitable loci. Our findings of differences in microsatellite isolation are consistent with the available data on differences in genomic characteristics across these taxa. In the beetle repeated isolation of identical motifs, difficulties in primer development, and multibanded products caused loss of most candidate clones.

While the inclusion of nuclear markers should preferentially be considered for future studies, there is no need to abandon mtDNA as long as tests for the known mtDNA artefacts are performed. In this study we present additional data and test previous phylogeographical studies of Pityogenes chalcographus. We did not detect nuclear copies (numts) of the previously used mitochondrial markers by performing a combined long range/nested PCR of the COI gene and by an in silico analysis of the COI sequence data. This confirms the robustness of our previous phylogenetic study of P. chalcographus. Results of an in-situ hybridization of Wolbachia in P. chalcographus confirm the presence of this endosysmbiont in this species. However, we did not detect a correlation between infection status, geographical region and mtDNA haplotypes. The hybridisation data also support a previous hypothesis that infections do not result from parasitoids or parasitic nematodes, insect surface or laboratory contaminations and are hence a true infection of P. chalcographus. We conclude that the deep structure found in mitochondrial populations of P. chalcographus indeed represents the evolutionary history of European populations.10aPityogenes chalcographus1 aArthofer, Wolfgang1 aAvtzis, Dimitrios, N.1 aRiegler, Markus1 aStauffer, Christian  uhttp://pensoftonline.net/zookeys/index.php/journal/issue/view/5801631nas a2200157   4500008004100000020002500041245014100066210006900207260000900276300000900285490000900294520106800303653002601371100002001397856005601417       2012                        eng d  a0033-2615; 1687-743800aBark Beetles, Pityogenes bidentatus, Orienting to Aggregation Pheromone Avoid Conifer Monoterpene Odors When Flying but Not When Walking0 aBark Beetles Pityogenes bidentatus Orienting to Aggregation Pher  c2012  a1-100 v20123 aPrevious studies and data presented here suggest that odors from healthy host Scotch pine (Pinus sylvestris) and nonhost Norway spruce (Picea abies), as well as major monoterpenes of these trees at natural release rates, significantly reduce the attraction of flying bark beetles, Pityogenes bidentatus, of both sexes to their aggregation pheromone components grandisol and cis-verbenol in the field, as tested by slow rotation of trap pairs. In contrast, P. bidentatusmales and females walking in an open-arena olfactometer in the laboratory did not avoid monoterpene vapors at release rates spanning several orders of magnitude in combination with aggregation pheromone. The bark beetle may avoid monoterpenes when flying as a mechanism for avoiding nonhost species, vigorous and thus unsuitable host trees, as well as harmful resinous areas of hosts. Inhibition of this dlight avoidance response in beetles after landing would allow them to initiate, or to find and enter, gallery holes with high monoterpene vapor concentrations inorder to feed and reproduce.10aPityogenes bidentatus1 aByers, John, A.  uhttp://www.hindawi.com/journals/psyche/2012/940962/
