Les fourmis (Hymenoptera : Formicidae) introduites de France métropolitaine et en Belgique, avec un focus sur les serres

International audienceThe monitoring of introduced species is becoming more important as global trade intensifies. Although ants make up a larger proportion of species on the list of the most invasive species in the world compared with other groups, little is known about the occurrence of those introduced in France, especially inside heated buildings. Here we review the literature available for mainland France and Belgium and report the results of a survey conducted with the help of tropical building managers between 2014 and 2016. We report for the first time in France the presence of Technomyrmex vitiensis and Plagiolepis alluaudi in multiple greenhouses. Technomyrmex difficilis was also found in one greenhouse for the first time in Europe. The diversity of introduced ants in greenhouses is very low, and these buildings are most often dominated by one or two species. We compared the most recent data and those collected throughout the twentieth century and showed that ant communities have changed substantially. Greenhouses could be responsible for the introduction of invasive species because they regularly import exotic plants, but we found no evidence that the three species of invasive ants present outdoors in France were introduced from greenhouses, where they rarely occur. We also report that introduced ants are pests in greenhouses because they disperse scale insects and kill biological control agents. The suppression of these ants could ease the maintenance of plants inside greenhouses.l’intensification des échanges internationaux, la veille sur les espèces introduites devient de plus en plus pertinente. Les Fourmis représentent une proportion importante des espèces considérées comme les plus envahissantes, et pourtant la littérature sur l’occurrence de Fourmis introduites en France est peu abondante et peu détaillée, en particulier en ce qui concerne les bâtiments chauffés. Cet article dresse le bilan des connaissances sur ce sujet pour la France métropolitaine et la Belgique, en se basant sur les données de la littérature et d’une enquête menée auprès des gestionnaires d’espaces tropicalisés entre 2014 et 2016. Technomyrmex vitiensis et Plagiolepis alluaudi ont été détectées pour la première fois dans plusieurs serres de France. De même, Technomyrmex difficilis a été trouvée dans une serre pour la première fois en Europe. Le cortège d’espèces introduites présentes dans les serres tropicales est peu diversifié, et souvent dominé par une ou deux espèces. En comparant les données actuelles avec celles du début du xxe siècle, il apparaît que la composition de ce cortège s’est modifiée. Les espaces tropicalisés pourraient être responsables de l’introduction d’espèces envahissantes car ils importent régulièrement des plantes exotiques, mais les trois espèces de Fourmis introduites et envahissantes présentes en extérieur n’ont visiblement pas été introduites par ce biais et sont peu représentées dans les serres. Cependant, les Fourmis introduites nuisent aux plantes des serres tropicales en protégeant et propageant les Cochenilles, et parfois en détruisant les auxiliaires de lutte biologique. La mise en place de moyens de lutte contre ces Fourmis pourrait faciliter le maintien de certaines espèces de plantes tropicales en serre

FORMIDABEL: The Belgian Ants Database.

peer reviewed[en] UNLABELLED: FORMIDABEL is a database of Belgian Ants containing more than 27.000 occurrence records. These records originate from collections, field sampling and literature. The database gives information on 76 native and 9 introduced ant species found in Belgium. The collection records originated mainly from the ants collection in Royal Belgian Institute of Natural Sciences (RBINS), the 'Gaspar' Ants collection in Gembloux and the zoological collection of the University of Liège (ULG). The oldest occurrences date back from May 1866, the most recent refer to August 2012. FORMIDABEL is a work in progress and the database is updated twice a year. THE LATEST VERSION OF THE DATASET IS PUBLICLY AND FREELY ACCESSIBLE THROUGH THIS URL: http://ipt.biodiversity.be/resource.do?r=formidabel. The dataset is also retrievable via the GBIF data portal through this link: http://data.gbif.org/datasets/resource/14697 A dedicated geo-portal, developed by the Belgian Biodiversity Platform is accessible at: http://www.formicidae-atlas.be PURPOSE: FORMIDABEL is a joint cooperation of the Flemish ants working group "Polyergus" (http://formicidae.be) and the Wallonian ants working group "FourmisWalBru" (http://fourmiswalbru.be). The original database was created in 2002 in the context of the preliminary red data book of Flemish Ants (Dekoninck et al. 2003). Later, in 2005, data from the Southern part of Belgium; Wallonia and Brussels were added. In 2012 this dataset was again updated for the creation of the first Belgian Ants Atlas (Figure 1) (Dekoninck et al. 2012). The main purpose of this atlas was to generate maps for all outdoor-living ant species in Belgium using an overlay of the standard Belgian ecoregions. By using this overlay for most species, we can discern a clear and often restricted distribution pattern in Belgium, mainly based on vegetation and soil types
