| Des recherches récentes ont montré que la diversité génétique des arbres peut conditionner l’assemblage des communautés associées et ainsi façonner l’évolution des écosystèmes. Les arbres peuvent héberger une importante communauté d’insectes et certains de leurs traits fonctionnels (débourrement végétatif, surface foliaire...) peuvent avoir une influence majeure sur la consommation des insectes.L’objectif de cette étude est d’évaluer comment l’herbivorie interagit avec la diversité génétique intraspécifique de huit clones de peuplier noir du bassin de la Loire. Nous avons installé en avril 2009 un dispositif expérimental en milieu naturel au sein de la ripisylve à peuplier noir de l’ISS Loire (intensive study site, http://www.evoltree.eu/), comprenant 120... |

| On étudie l’impact de l’utilisation gallo-romaine ancienne sur la diversité des espèces d’arthropodes dans la forêt de Thuilley-aux-Groseilles. Dans 6 sites (3 proches des habitats gallo-romains et 3 en zone non perturbée), les arthropodes ont été piégés dans 4 types de piège pendant une saison de végétation. Sur les 8914 individus identifiés, 433 espèces ont été déterminées. La diversité de Shannon moyenne par site est élevée (5,5 binons). Il n’apparaît pas de différences importantes entre types d’utilisation ancienne pour les paramètres classiques de diversité (richesse spécifique, diversité de Shannon, nombre total d’individus observés). Par contre, les cortèges d’espèces présents sur les sites perturbés ou non perturbés par l’agriculture ancienne se... |

| The absolute configuration of the primary component of the maritime pine scale (Matsucoccus feytaudi) pheromone (i.e., (8E, 10E)-3,7,9-trimethyl-8,10-dodecadien-6-one) was determined as 3S,7R by field-trapping experiments using synthetic stereoisomers and according to previous NMR considerations. The 3R,7R isomer showed similar activity to 3S,7R, whereasM. feytaudi males responded very weakly to the two other candidates (3R,7S and 3S,7S). Further studies were conducted to optimize scale trapping for monitoring scale populations. Results of these studies showed that the trapping efficiency was related to pheromone dose, trap area, and wind speed but not to trap height. |

| Gas chromatography-electroantennographic detection analysis of sex pheromone gland extracts of the common forest looper Pseudocoremia suavis (Lepidoptera: Geometridae), a polyphagous defoliator of introduced Pinaceae and many New Zealand trees, revealed four compounds that elicited antennal responses. The two major active compounds (6Z)-cis-9,10-epoxynonadec-6-ene and (3Z,6Z)-cis-9,10-epoxynonadeca-3,6-diene were identified by comparison with known standards. Of the two minor active compounds, one was tentatively identified as (3Z,6Z)-cis-9,10-epoxyhenicosa-3,6-diene, whereas the other could not be identified because of insufficient amounts in extracts. (6Z)-cis-9,10-Epoxynonadec-6-ene, (3Z,6Z)-cis-9,10-epoxynonadeca-3,6-diene, and... |

| Recent research suggests that genetic diversity in tree population may shape associated species assemblages and then drive ecosystem processes. Trees can support large numbers of insect species and some functional traits of trees have been shown to have major influence on insect communities and resultant damage. Studying the response of insect herbivorepopulations to the genetic diversity of tree populations is therefore a relevant approach to test community genetics hypotheses.The objective of our study was to evaluate how insect herbivory is affected by genotypes of Populus nigra, a dominant native poplar species in riparian forests of Europe. In a field experiment, we planted eight native P. nigra clones in plots of increasing genetic diversity with... |

| The kairomonal activity of the sex pheromones of three pine bast scales, Matsucoccus feytaudi, Matsucoccus josephi, and Matsucoccus matsumurae, as well as a new analog of the M. feytaudi sex pheromone, were investigated in pine forests of France, Portugal, and Italy. The response of the maritime pine bast scale predators, Elatophilus spp. and Hemerobius stigma, was used to test the influence of trapping methods, kairomone composition, and dose. Both predators showed significant attraction to all compounds except to the sex pheromone of M. josephi. Significant increase in captures was observed as a function of dose, and within the studied dose range, up to 2200 mu g, no threshold saturation limits were observed for any of the attractive compounds. Trap... |

| Losses of natural and semi-natural forests, mostly to agriculture, are a significant concern for biodiversity. Against this trend, the area of intensively managed plantation forests increases, and there is much debate about the implications for biodiversity. We provide a comprehensive review of the function of plantation forests as habitat compared with other land cover, examine the effects on biodiversity at the landscape scale, and synthesise context-specific effects of plantation forestry on biodiversity. Natural forests are usually more suitable as habitat for a wider range of native forest species than plantation forests but there is abundant evidence that plantation forests can provide valuable habitat, even for some threatened and endangered... |

| Gas chromatographic analysis of the volatile terpenes of the wood oleoresin of maritime pines showed that the relative proportions of terpenes within the same tree did not vary according to sampling height and date. Pruning and tree vigor did not affect terpene profiles, but oleoresin composition varied widely from tree to tree. The trees attacked by Dioryctria sylvestrella contained a significantly higher percentage of limonene, longipinene, and copaene, and a discriminant analysis, using the relative percentage of six terpenes, significantly separated infested and uninfested trees. The olfactory sensitivity of adult moths to a series of 20 volatile chemicals, including maritime pine oleoresin components, was evaluated with the electroantennogram method.... |

| Species-rich plant communities may be more resistant to invasive herbivores because of reduced host-plant accessibility and increased natural enemy diversity and abundance. We tested these hypotheses in Corsica, a Mediterranean island recently invaded by the maritime pine bast scale, Matsucoccus feytaudi Duc., which causes widespread tree mortality in Pinus pinaster Ait. The endemic Matsucoccus pini Green infests Corsican pine, Pinus nigra laricio Poiret, where it is controlled by the native predatory bug, Elatophilus nigricornis Zetterstedt. As revealed by kairomone trapping, E. nigricornis was most abundant in pure Corsican pine in areas not yet colonized by M. feytaudi, and in pure maritime pine its density decreased with the distance from the nearest... |
