| Le recrutement d’arthropodes phytophages par des conifers exotiques introduits en Europe sans congénères autochtones a été comparé à celui de conifères exotiques présentant des congénères natifs. En 130 ans de plantationsimportantes en Europe, le sapin de Douglas (Pseudotsuga menziesii (Mirb.) Franco) n’a recruté que 87 espèces d’arthropodes, soit seulement 33,9 % du total des 257 espèces qui y sont associées dans la zone d’origine. Les espèces exotiques de Cupressacées sans congénères natifs n’ont recruté que de 3,4 à 57,9 % autant d’espèces que dans leur zone native. Dans tous ces cas, la plupart des insectes sont polyphages et capables de se nourrir sur différentes familles de conifèreset (ou) d’angiospermes. A l’opposé, la plupart des insectes... |

| The seeds of both cedar-of-Lebanon (Cedrus libani) and Cyprus cedar (Cedrus brevifolia) are attacked in their natural range by a specialised chalcid, Megastigmus schimitscheki. From 1995 to 1999, seeds were screened for insect damage in the main cedar plantations of southern France, as well as in the stands where cedar is mixed with firs (Abies spp.). X-rays were used to identify chalcid-infested seeds from which the insects were then reared. The surveys revealed the presence of M. schimitscheki in all the stands of Atlas cedar, Cedrus atlantica, planted at Mt Ventoux, southeastern France. The chalcid also infested seeds of an exotic fir, Abies pinsapo, planted in the same area. However, it has not yet reached the cedar plantations in southwestern France,... |

| A literature survey identified 403 primary research publications that investigated the ecological effects of invasive alien insects and/or the mechanisms underlying these effects. The majority of these studies were published in the last 8 years and nearly two-thirds were carried out in North America.These publications concerned 72 invasive insect species, of which two ant species, Solenopsis invicta and Linepithema humile, accounted for 18% and 14% of the studies, respectively.Most publications investigated effects on native biodiversity at population or community level. Genetic effects and, to a lesser extent, effects on ecosystem services and processes were rarely explored. We review the effects caused by different insect invaders according to: their... |

| Information relevant to invasion processes and invasive alien insect species management in Central Europe was extracted from two databases: a compilation of two inventories of alien insects in Austria and Switzerland, and a list of interceptions of non indigenous plant pests in Europe gathered by the European and Mediterranean PlantProtection Organisation (EPPO) for the period 1995-2004. For one third of the insects established in Switzerland and Austria, the region of origin is unclear. Others come mainly from North America, Asia and the Mediterranean region. Among the intercepted insects, 40% were associated with commodities from Asia, 32% from Europe and only 2% from North merica.Sternorrhyncha, Coleoptera and Psocoptera were particularly well... |

| The project aimed at contributing to understand the ecological and genetic mechanisms underlying the possibilities of establishment of exotic insects in the genus Megastigmus (Hymenoptera: Torymidae), specialized in the exploitation of forest seeds, and at defining suitable methods of monitoring and management of the invasive insect populations. For that, we intended to compare two distinct models host seed/ Megastigmus, crossing different first date of invasion and taxonomic structure of the forests: (i) true firs (Abies)/Megastigmus where the resource, indigenous, is exploited by a native species, M. suspectus, in competition with at least 5 invasive species of North American origin, and (ii) true cedars (Cedrus)/Megastigmus where the resource, itself... |

| A total of 39 insect species, mostly seed chalcids in the genus Megastigmus (Hymenoptera), but also midges (Diptera), are listed as potential seed-borne invaders of Chinese conifers. Although the number of native seed insects per conifer genus does not differ between China and other biogeographical regions, there are significantly fewer seed insects associated with each conifer genus in China than potential invaders. The eventual success of the invaders is likely to depend on the presence of native Chinese conifers that are congeneric with the original host, or on the presence of the original host as an exotic. When a substantial entomofauna is already associated with cones, competition for seed resources may limit the potential impact of invaders because... |

| We present the identification of the sex pheromone in the pine sawfly, Gilpinia pallida, including analysis of the female pheromone content, male antennal response and attraction in the field, and synthesis of the most active pheromone component. Several 3,7-dimethyl-2-alkanols were identified from female whole-body extracts, including some compounds with a 2R configuration. This is the first observation of such compounds in a pine sawfly species. Antennae of male G. pallida responded strongly in electroantennograph (EAG) recordings to the (2S,3R,7R)-isomers of the propionates of 3,7-dimethyl-2-tridecanol, 3,7-dimethyl-2-tetradecanol, and 3,7-dimethyl-2-pentadecanol, as well as to the acetates of the tri- and pentadecanols (the acetate of the tetradecanol... |
