Large diff erences in habitat affi nity are observed between alien taxonomic groups. Phytophagous species are predominant among aliens, representing 47.2% of species alien to Europe. 2010-01-01T00:00:00Z http://hdl.handle.net/10362/4035 Title: Hymenoptera. Authors: Rasplus, Jean-Yves; Villemant, Claire; Paiva, Maria Rosa; Delvare, Gérard; Roques, Alain Editors: Roques, A et al. Abstract: We present the fi rst review of Hymenoptera alien to Europe. Our study revealed that nearly 300 species of Hymenoptera belonging to 30 families have been introduced to Europe. In terms of alien species diversity within invertebrate orders, this result ranks Hymenoptera third following Coleoptera and Hemiptera. Two third of alien Hymenoptera are parasitoids or hyperparasitoids that were mostly introduced for biological control purposes. Only 35 phytophagous species, 47 predator species and 3 species of pollinators have been introduced. Six families of wasps (Aphelinidae, Encyrtidae, Eulophidae, Braconidae, Torymidae, Pteromalidae) represent together with ants (Formicidae) about 80% of the alien Hymenoptera introduced to Europe. Th e three most diverse families are Aphelinidae (60 species representing 32% of the Aphelinid European fauna), Encyrtidae (55) and Formicidae (42) while the Chalcidoidea together represents 2/3 of the total Hymenoptera species introduced to Europe. Th e fi rst two families are associated with mealybugs, a group that also included numerous aliens to Europe. In addition, they are numerous cases of Hymenoptera introduced from one part of Europe to another, especially from continental Europe to British Islands. Th ese introductions mostly concerned phytophagous or gall- maker species (76 %), less frequently parasitoids. Th e number of new records of alien Hymenoptera per year has shown an exponential increase during the last 200 years. Th e number of alien species introduced by year reached a maximum of 5 species per year between 1975 and 2000. North America provided the greatest part of the hymenopteran species alien to Europe (96 species, 35.3%), followed by Asia (84 species, 30.9%) and Africa (49 species, 18%). Th ree Mediterranean countries (only continental parts) hosted the largest number of alien Hymenoptera: Italy (144 spp.), France (111 spp.) and Spain (90 spp.) but no correlation was found with the area of countries. Intentional introduction, mostly for biological control, has been the main pathway of introduction for Hymenoptera. Consequently, the most invaded habitats are agricultural and horticultural as well as greenhouses. To the contrary, Hymenoptera alien in Europe are mostly associated with woodland and forest habitats. Ecological and economic impacts of alien Hymenoptera have been poorly studied. Ants have probably displaced native species and this is also true for introduced parasitoids that are suspected to displace native parasitoids by competition, but reliable examples are still scarce. Th e cost of these impacts has never been estimated. 2010-01-01T00:00:00Z http://hdl.handle.net/10362/4033 Title: The saltopteran fauna of Portugal: new records and biogeographical aspects (Orthopteroidea) Authors: Schmidt, Gerhard H; Martinho, Ana Paula; Paiva, Maria Rosa 2009-01-01T00:00:00Z http://hdl.handle.net/10362/5931 Title: Vibroacoustic disease II: The biological and acoustical basis of low frequency noise induced pathology Authors: Melo, João Joanaz de; Motylewsky, J; Kotlicka, E; Castelo Branco, N; Alves-Pereira, M Description: Proceedings Institute of Acoustics (UK); vol. 25, nº2, p. 72-78. 2003-01-01T00:00:00Z
