The blend composed of [alpha]-pinene, ethanol, ipsenol, ipsdienol and 2-methyl-3-buten-2-ol was very efficient in trapping the cerambycids Monochamus galloprovincialis, Acanthocinus griseus and Arhopalus syriacus and the scolytids Ips sexdentatus, Orthotomicus erosus and Hylurgus ligniperda. This blend is proposed for operational surveys of Bursaphelenchus spp. associated with these beetles. Comparison of the capture levels with cross-vane and funnel traps baited with [alpha]-pinene, ethanol, ipsenol, ipsdienol, 2-methyl-3-buten-2-ol and cis-verbenol revealed the higher efficacy of the cross-vane traps for the above-mentioned cerambycids and the scolytid I. sexdentatus but greater effectiveness of the funnel traps in capturing H. ligniperda and O. erosus. Cross-vane traps were more efficient in capturing large numbers of these insects. Data on non-target xylophagous beetles and predator species are also reported.10aIps sexdentatus1 aFrancardi, V.1 ade Silva, J.1 aPennacchio, F.1 aRoversi, P., F.  uhttps://weevil.myspecies.info/pine-volatiles-and-terpenoid-compounds-attractive-european-xylophagous-species-vectors-bursaphelench02821nas a2200193   4500008004100000020001400041245013800055210006900193260000800262300001200270490000800282520211500290653002002405100001802425700001602443700001402459700002002473856013402493       2012                        eng d  a0931-204800aField response of the six-toothed pine bark beetle, Ips sexdentatus (Col.: Curculionidae, Scolytinae), to pheromonal blend candidates0 aField response of the sixtoothed pine bark beetle Ips sexdentatu  cJul  a431-4440 v1363 aThe identification and description of the chemical signals involved in the aggregation of bark beetles may lead to the development of integrated pest management strategies using synthetic pheromones. Ips sexdentatus Boern. (Col.: Scolytinae) colonizes trees of the Pinus genus across Europe, causing severe damage in occasions. The effect of cis-verbenol, ipsenol, 2-methyl-3-buten-2-ol (MB) and myrtenol in relation to the major pheromonal compound ipsdienol on the aggregation behaviour of I. sexdentatus was studied on four field bioassays. The ternary blend of racemic ipsdienol, cis-verbenol and racemic ipsenol consistently caught the highest number of bark beetles, resulting in large standardized mean differences (dunbiased > 0.8). The binary blends between ipsdienol and ipsenol, and ipsdienol and cis-verbenol also improved the performance of ipsdienol, although only ipsenol did it significantly. On the other hand, catches were reduced (dunbiased = -0.96) when MB was released along ipsdienol, although the effect was found to be non-significant. On a third bioassay, the relative release rates between ipsdienol, ipsenol and cis-verbenol were studied. Although no differences were found between the ternary blends, a ratio of 1 : 0.25 : 0.5 for ipsdienol, ipsenol and cis-verbenol, respectively, scored the strongest effect size (dunbiased = 1.17). A fourth bioassay studied the behavioural effects of myrtenol and found no significant modifications to previously established findings. Myrtenol on its own attracted almost no individuals of I. sexdentatus. High numbers of bark beetle predators Thanasimus formicarius L. and Temnochila caerulea Olivier were trapped during the trials. The binary blend between ipsdienol and ipsdienol was shown to catch the highest significant amount of T. formicarius, whereas numbers of T. caerulea caught were highest on the binary blend between cis-verbenol and ipsdienol. Presented results establish the ternary blend between ipsdienol, ipsenol and cis-verbenol as a reference functional aggregative lure ready to be used on the management of I. sexdentatus.10aIps sexdentatus1 aEtxebeste, I.1 aAlvarez, G.1 aPerez, G.1 aPajares, J., A.  uhttps://weevil.myspecies.info/field-response-six-toothed-pine-bark-beetle-ips-sexdentatus-col-curculionidae-scolytinae-pheromonal01780nas a2200181   4500008004500000020001400045245011200059210006900171260000900240300001200249490000700261520110600268653002401374653002001398653002401418100002301442856013301465       2008                        Engldsh    a0370-432700aBursaphelenchus species with their natural vectors in Italy: distribution and essential diagnostic features0 aBursaphelenchus species with their natural vectors in Italy dist  c2008  a111-1170 v913 aAccording to data collected during several surveys, accomplished from 1992 to 2007 in coniferous and deciduous trees, together with those obtained from Servizi Fitosanitari Regionali, in order to the request of European Union, a total of twelve nominal Bursaphelenchus species plus one, not yet identified, were collected in Italy. Among these species Bursaphelenchus mucronatus Mamiya & Enda and B. eremus Ruhm (Goodey) appeared to be the most frequently found in coniferous and deciduous trees respectively. For B. eggersi Ruhm (Goodey), B. idius Ruhm (Goodey) and B. silvestris (Lieutier & Laumond) Baujard, species already reported in Europe, this is the first record of their occurrence in Italy; for B. minutus Walia, Negi, Bajaj & Kalia, as far as we know, this is the second record in the world after India, where the species has been first described. Diagnostic characters, illustrated by microphotographs or drawings, are described for the Bursaphelenchus species occurring in Italy and an extensive review on their occurrence throughout the world, host range and insect vectors is reported.10aHylurgus ligniperda10aIps sexdentatus10aScolytus intricatus1 aCarletti, Beatrice  uhttps://weevil.myspecies.info/bursaphelenchus-species-their-natural-vectors-italy-distribution-and-essential-diagnostic-features01935nas a2200169   4500008004100000020002500041245024400066210006900310260000900379300000800388490000900396520124200405653002001647100001801667700002401685856005601709       2012                        eng d  a0033-2615; 1687-743800aFlight Dynamics and Abundance of Ips sexdentatus (Coleoptera: Curculionidae: Scolytinae) in Different Sawmills from Northern Spain: Differences between Local Pinus radiata (Pinales: Pinaceae) and Southern France Incoming P. pinaster Timber0 aFlight Dynamics and Abundance of Ips sexdentatus Coleoptera Curc  c2012  a1-60 v20123 aIn January 2009, the windstorm "Klaus" struck the southern part of France, affecting 37.9 million m3 of maritime pine Pinus pinaster Aiton (Pinales: Pinaceae). This breeding plant material favored the outbreak of Ips sexdentatus (B orner) (Coleoptera: Curculionidae: Scolytinae). As much of this timber is imported to the Basque Country (northern Spain), a potential risk to conifer stands is generated, due to the emergence of the incoming beetles. Thus, flight dynamics and beetle abundance were compared in different sawmills, according to the timber species (either local P. radiata D. Don or imported P. pinaster). A maximum flight peak of I. sexdentatus was observed in mid-June in P. pinaster importing sawmills, whereas a second lighter peak occurred in September. In contrast, only a maximum peak in mid-June was observed in P. radiata inhabiting beetles, being significantly smaller than in local P. pinaster trading sawmills. In addition, significant differences were found between imported P. pinaster and P. radiata regarding the number of insects beneath the bark. The development of IPM strategies for controlling I. sexdentatus populations is recommended, due to the insect abundance found in P. pinaster imported timber.10aIps sexdentatus1 aLopez, Sergio1 aGoldarazena, Arturo  uhttp://www.hindawi.com/journals/psyche/2012/145930/
