We studied the attractiveness of the host volatiles [alpha]-pinene and ethanol at a range of release rates, alone or in combination, to T. destruens, in order to develop an attractive lure for the management of this beetle. T. destruens was attracted slightly to the host volatile [alpha]-pinene, but a strong synergistic effect was found in the attraction towards monoterpene when ethanol was added to the bait. The highest catches of T. destruens were obtained by the optimal blend releasing 300 mg/day of [alpha]-pinene and 900 mg/day of ethanol. In contrast to data reported for the related species T. piniperda, Mediterranean pine shoot beetles were clearly attracted to baits releasing ethanol alone (1350 mg/day). trans-Verbenol, which was also added to host volatiles in some tests, did not affect the response. The use of the attractive blend proposed would have a low impact on the natural enemy population of Thanasimus formicarius because of asynchronies in flight periods. Other non-target insects, such as the facultative predator or competitor Oxipleurus nodieri, were also significantly attracted. These results allow the development of an operative lure for the effective monitoring of T. destruens, although improvements by the addition of other host volatiles should be studied.10aTomicus destruens1 aGallego, D.1 aGalian, J.1 aDiez, J., J.1 aPajares, J., A.  uhttps://weevil.myspecies.info/kairomonal-responses-tomicus-destruens-col-scolytidae-host-volatiles-alpha-pinene-and-ethanol02211nas a2200169   4500008004500000020001400045245013400059210006900193260001300262300001200275490000700287520155900294653002201853100001601875700001501891856013501906       2008                        Engldsh    a0947-574500aHierarchical structure of mitochondrial lineages of Tomicus destruens (Coleoptera, Scolytidae) related to environmental variables0 aHierarchical structure of mitochondrial lineages of Tomicus dest  cNovember  a331-3390 v463 aWe investigated here the relation of environmental variables with the distribution of mitochondrial lineages using a bark beetle species of Mediterranean distribution as a model. We analysed a total number of 460 DNA sequences of Tomicus destruens provided by intensive and extensive collection and GenBank entries. We combined phylogeography and regression models to study the role of five environmental predictors at fine scale in the distribution of a local genealogy. The analysis revealed a high genetic diversity, with 52 haplotypes present in Sierra Espuna forest (SE Spain) and 21 haplotypes in the other 14 Spanish populations, all included in the western clade of the Mediterranean phylogeography of the species. We found a micro-distribution of the species related to altitude and putative niche segregation between lineages associated with the micro-environmental conditions of their host pine trees. We compared the phylogeographic hypothesis obtained here with the phylogeography obtained integrating our data with all data published elsewhere. Here, we demonstrate a relation between the environmental heterogeneity and the haplotypic diversity at Mediterranean Basin scale. This analysis allows us to support the evolutionary scenario where the phylogeography and current molecular diversity of T. destruens is a consequence of the recolonization from two principal refugia at both extremes of the Mediterranean Basin and, according to our data, we propose that the heterogeneity of habitats allows fixation of the mitochondrial lineages.10aTomicus destruens1 aGallego, D.1 aGalian, J.  uhttps://weevil.myspecies.info/hierarchical-structure-mitochondrial-lineages-tomicus-destruens-coleoptera-scolytidae-related-enviro
