Resumen: El objetivo de este trabajo fue determinar la abundancia mitocondrial hepática en dos genotipos Holstein en un sistema pastoril durante lactancia media-tardía. Para este trabajo se utilizaron vacas del genotipo Holstein neozelandés y del genotipo Holstein norteamericano, las mismas pastorearon una pastura mixta de Medicago sativa y Dactylis glomerata y suplementadas con concentrados y reservas forrajeras. Se tomaron biopsias de hígado y
se analizó la expresión génica del factor de transcripción peroxisome proliferator-activated receptor gamma coactivator 1-alpha (controlador maestro de la biogénesis mitocondrial; PPARGC1A), la actividad citrato sintasa y la relación ADN mitocondrial / ADN nuclear. No se encontraron diferencias entre genotipos en la expresión de PPARGC1A, sin embargo, tanto la actividad citrato sintasa como la relación ADN mitocondrial / ADN nuclear fueron mayores para el genotipo Holstein neozelandés. Una mayor abundancia mitocondrial es clave para el mantenimiento de la homeostasis energética, elemento crucial para la mejor adaptación a los cambios fisiológicos.
Summary:The aim of this work was to determine the hepatic mitochondrial abundance in two Holstein genotypes in a pastoral system during mid-late lactation. For this study, cows of the New Zealand Holstein genotype and the North American Holstein genotype were used. Cows grazed a mixed pasture of Medicago sativa and Dactylis glomerata and were supplemented with concentrate and forage reserves. Liver biopsies were taken and the gene expression
of the peroxisome proliferator-activated receptor gamma coactivator 1-alpha – (a master regular of mitochondrial biogenesis, PPARGC1A) transcription factor, the citrate synthase activity, and the mitochondrial DNA / nuclear DNA ratio were analyzed. No differences were found be#2;tween genotypes in the expression of PPAR#2;GC1A, however, both citrate synthase activity and the mitochondrial DNA / nuclear DNA ra#2;tio were higher for the New Zealand Holstein
genotype. Greater mitochondrial abundance is key to maintaining energy homeostasis, a crucial element for a better adaptation to physiolo#2;gical changes.

ABSTRACT.
Several European and Mediterranean species of pine bark beetles (Coleoptera: Curculionidae: Scolytinae) have become established in North America and the southern hemisphere, posing a novel threat to planted and naturally-occurring pine forests. Our objectives were to investigate (1) the occurrence and relative abundance of pine bark beetles in these regions, and (2) the trapping performance of different blends of multispecies lures. In 2016?2017 a network of interception traps was installed in six non-European countries (Argentina, Australia, New Zealand, South Africa, the United States, and Uruguay), and in six European countries (France, Greece, Hungary, Italy, Portugal, and Spain) for comparison. Half of the traps were baited with alpha-pinene and ethanol, and the other half with alpha-pinene, ethanol, and a combination of bark beetle pheromones (ipsdienol, ipsenol, and Z-verbenol). Five Mediterranean scolytine species (Hylurgus ligniperda, Hylastes ater, H. angustatus, Orthotomicus erosus, and O. laricis) were found in non-European countries. Hylurgus ligniperda and Hylastes ater were the most widespread species found in several of the invaded regions, while O. laricis and H. angustatus occurred only in Argentina and South Africa, respectively. Despite large variation among species and countries, most species were trapped with the blend containing bark beetle pheromones, except O. erosus, which was more attracted to alpha-pinene and ethanol alone. This study represents the first step towards the development of an international monitoring protocol based on multi-lure traps for the survey and early-interception of invasive alien bark beetle species.
