PATRICK PAGEAT, IRSEA, Membre RESUME Malgré des inconvénients rédhibitoires, l’utilisation de molluscicides reste prédominante dans les stratégies de lutte contre les gastéropodes terrestres, une situation qui appelle au développement d’alternatives. Bien que les gastéropodes terrestres reposent essentiellement sur la chémodétection pour la réalisation d’un grand nombre d’interactions capitales avec leur environnement, leur perception de la prédation reste largement méconnue malgré son importance écologique. Nous avons donc étudié l’altération de comportements de maintenance chez deux espèces de gastéropodes terrestres nuisibles, la limace Deroceras reticulatum et l’escargot Xeropicta derbentina, en présence de composés chimiques issus de différentes espèces de carabes, une catégorie importante de prédateurs mallacophages. Les résultats obtenus indiquent que les caractéristiques écologiques des prédateurs sont cruciales dans la perception de la pertinence de la menace par ces gastéropodes. Mots-clés : carabes ; comportements de maintenance ; gastéropodes terrestres ; relations proie- prédateur ; sémiochimiques ABSTRACT Despite crippling drawbacks, molluscicides remain predominant in strategies employed against terrestrial gastropods pests, a situation that call for the development of alternatives. Although chemodetection drive many crucial interactions in terrestrial gastropods, their perception of predation remains largely unknown despite its ecological importance. We investigated the alteration of self-maintenance behaviours of two harmful land gastropods, the slug Derocers reticulatum and the snail Xeropicta derbentina, exposed to chemical compounds from different ground beetle species, an important category of gastropod predators. The results obtained indicate that the ecological features of the predators are crucial for the perception of the relevance of the predation threat by these gastropods. Keywords: ground beetles; predator-prey relationships; terrestrial gastropods; self-maintenance behaviour; semiochemicals i REMERCIEMENTS Un travail de thèse n’est pas l’œuvre d’un simple individu isolé mais est au contraire le fruit du concours d’un ensemble de personnes, c’est pourquoi je souhaite, dans les quelques lignes qui suivent, remercier celles qui ont contribuées, scientifiquement et/ou moralement, à la réalisation de ce travail de doctorat. Je tiens tout d’abord à exprimer ma gratitude envers mes directeurs de thèse, Patrick Pageat et Antoine Brin, pour la confiance qu’ils m’ont accordée en me laissant une grande autonomie dans la conduite de cette thèse tout en me faisant bénéficier de leurs qualités scientifiques et humaines, en particulier dans les moments clés de celle-ci. De même, je remercie vivement Hughes Lucas de Leyssac, directeur financier de l’IRSEA, qui a montré une confiance inébranlable en ces recherches en acceptant de les financer intégralement. Je souhaite remercier chaleureusement Claudio Lazzari et Pierre Zagatti pour avoir consacré de leur temps à lire, juger et apporter des critiques constructives à ce travail de thèse, ainsi que François Roman, Patrizia d’Ettorre et Fernando Guerrieri pour avoir accepté de participer au jury et pour avoir apporté leurs opinions éclairées. J’adresse mes remerciements les plus chaleureux à l’ensemble de l’équipe de l’IRSEA, en particulier Caroline, Benjamin et Myriam qui, en tant qu’amis et « colocataires » de bureau, ont bien souvent été en première ligne pour supporter mes moments de détresse mais qui ont su les faire oublier par leur bonne humeur sans cesse renouvelée. De même, Céline, Cécile et Alessandro ont été de précieux soutiens par leurs conseils avisés, que ce soit sur la rédaction des articles, du mémoire ou pour la compréhension des arcanes des statistiques. La réalisation des expérimentations a été possible grâce à la contribution d’entomologistes chevronnés. Je remercie ainsi très vivement Hervé Brustel, Enseignant- chercheur à l’EI Purpan, pour m’avoir fait partager ses connaissances des Carabidae. Sans lui je n’aurais pas eu l’honneur et le plaisir de rencontrer Alain Camard – expert, entres autres, de l’étude des phénomènes d’hybridations chez les carabes – qui m’a fait partager sa passion des carabes et qui m’a donné de précieux conseils sur leur élevage tout en me permettant d’admirer sa collection proprement hallucinante de carabidés et lépidoptères. De même, je ii remercie Julien Delnatte et Julie Fourrier pour leur aide précieuse dans la capture respectivement de carabes et de limaces, et d’avantage encore pour leur compagnie plus que sympathique. Je remercie Eve Landen pour sa disponibilité, ses relectures assidues et ses corrections de l’anglais qui ont contribué à la publication des articles. Une grande part du succès de cette thèse provient du soutien moral des proches, à commencer par mes parents et mes frères qui ont toujours été à mes côtés, malgré la distance géographique, et d’une écoute toujours très attentive. Je remercie Alexandra, Pierre, Guillaume, Régis et Olivier, mes amis de longue date qui m’ont insufflé du courage tout au long de ces années de doctorat, de même que les « italo-goultois », Elisa, Stefano et Pietro, qui ont ponctués cette thèse de soirées gastronomiques, arrosées et (très) décontractées. iii Sommaire RESUME/ABSTRACT --------------------------------------------------------------- i REMERCIEMENTS -------------------------------------------------------------------ii LISTE DES FIGURES ----------------------------------------------------------------- x LISTE DES PHOTOGRAPHIES ---------------------------------------------------- xi INTRODUCTION -------------------------------------------------------------------- 1 I Taxonomie, biologie et écologie des gastéropodes terrestres ------------- 2 I. 1 Les gastéropodes terrestres ------------------------------------------------------------------ 2 I. 1. a Place des gastéropodes terrestres au sein des mollusques -------------------------------------- 2 I. 1. b Caractéristiques morphologiques des gastéropodes terrestres --------------------------------- 7 Les formes de types « limaces » et « escargots » ------------------------------------------------- 9 Principales caractéristiques anatomiques de la forme de type « limace » --------------- 10 I. 1. c La perception sensorielle chez les gastéropodes terrestres ------------------------------------ 11 Vision ------------------------------------------------------------------------------------------------------- 11 Olfaction --------------------------------------------------------------------------------------------------- 13 iv I. 2 Importance agricole et sanitaire des gastéropodes terrestres----------------------- 18 I. 2. a Importance des gastéropodes terrestres en agriculture---------------------------------------- 19 I. 3 Caractéristiques spécifiques de Deroceras reticulatum et de Xeropicta derbentina -------------------------------------------------------------------------------------------------- 23 I. 3. a Deroceras reticulatum (Müller, 1774) ------------------------------------------------------------- 23 Taxonomie et caractéristiques morphologiques ------------------------------------------------------------ 23 Ecologie et cycle de développement --------------------------------------------------------------------------- 24 Régulation de l’activité -------------------------------------------------------------------------------------------- 26 I. 3. b Xeropicta derbentina (Krynicki, 1836) ------------------------------------------------------------- 28 Taxonomie et caractéristiques morphologiques ------------------------------------------------------------ 28 Ecologie, cycle de développement et importance agronomique --------------------------------------- 30 I. 4 Méthodes de contrôle des gastropodes terrestres -------------------------------------- 34 I. 4. a Contrôle chimique ------------------------------------------------------------------------------------- 35 Métaldéhyde et carbamates ------------------------------------------------------------------------------------- 35 Phosphate de fer ---------------------------------------------------------------------------------------------------- 38 I. 4. b Méthodes alternatives ------------------------------------------------------------------------------- 38 Pratiques agricoles ------------------------------------------------------------------------------------------------- 39 Contrôle biologique par les prédateurs et les parasites

  • Ground Beetle Communities (Coleoptera, Carabidae) of Holm Oak-Forests (Quercus Ilex) and Their Degradation Stages on Mallorca (Iles Baleares, Spain)
    Ground beetle communities (Coleoptera, Carabidae) of Holm oak-forests (Quercus ilex) and their degradation stages on Mallorca (Iles Baleares, Spain) Raphael SCHULLER and Erik ARNDT Schuller, R. and Arndt, E. 2008. Ground beetle communities (Coleoptera, Carabidae) SHNB of Holm oak-forests (Quercus ilex) and their degradation stages on Mallorca (Iles Baleares, Spain). Boll. Soc. Hist. Nat. Balears, 51: 63-72. ISSN 0212-260X. Palma de Mallorca. Ground beetles (Coleoptera: Carabidae) were examined in the Serra de Tramuntana (Mallorca). These beetles serve as ecological indicators to describe effects of human impact in terrestrial habitats and are used in nature conservation. There were analysed holm oak (Quercus ilex) forest sites as well as garrigue sites in former oak forest SOCIETAT D’HISTÒRIA areas. A total of 17 Carabid species with 1810 individuals was recorded. One species, NATURAL DE LES BALEARS Pseudomasoreus canigoulensis, was found first time on the Balearic islands. The species numbers per site varied between 2-6 in forests and 5-10 in garrigues. Despite the lower species number, the forest sites had more individuals due to a large population density of Calosoma sycophanta, a specialized oak forest species. The ground beetle community changes clearly between forest and garrigue in the Serra de Tramuntana despite the fact that both habitat types are located in direct neighbourhood and that both habitat types are shared by many abundant species in other Mediterranean areas (e.g. Greek mountains). We must conclude that the decrease of forest area and forest fragmentation of Mallorca are connected with decrease and possible disappearing of typical (in part endemic) forest Carabidae which do not find secondary habitats in shrubland.

  • – 101 – Les Peuplements Des Coléoptères Du Marais Salé De L
    LES PEUPLEMENTS DES COLÉOPTÈRES DU MARAIS SALÉ DE L’embouCHURE DE LA TAFNA (ALGÉRIE) Samira BOUKLI HACENE 1, Karima HASSAINE 1 & Philippe PONEL 2 SUMMARY. — Coleopteran communities of the salt marsh at the mouth of the Tafna River (Algeria). — A study of Coleopteran communities was conducted between October 2009 and September 2010 in the salt marsh at the mouth of the Tafna River. Bimonthly trappings were carried out in five groups of vegetation and yielded 3833 specimens belonging to 140 species. This richness varies from one group to another (19 to 87 species). The high values are directly related to a shorter period of submersion, a lower salinity but also a greater floristic richness. Diversity indicators show that communities are diversified, regular and well structured with the exception of the samples from the lowest points where the highest salt concentrations are recorded. The highest richness and abundance are recorded mainly between early spring and early summer. Community composition is very different from one group to another ; the similarity index does not exceed 40 %. The spatial micro-distribution of grouping floristic species has been demonstrated through an ascend- ing hierarchical analysis. RÉSUMÉ. — Une étude des peuplements des Coléoptères a été réalisée entre octobre 2009 et septembre 2010 dans le marais salé de l’embouchure de la Tafna. Des piégeages bimensuels effectués dans cinq grou- pements de végétation ont fourni 3833 spécimens répartis en 140 espèces. Cette richesse spécifique varie d’un groupement à un autre (de 19 à 87 espèces). Les richesses élevées sont en relation directe avec une période de submersion moins longue, un taux de salinité moins élevé mais également une richesse floristi- que plus importante.
