Approche génétique de la dynamique spatiale de deux Hyménoptères envahissants au sein d’un écosystème forestier méditerranéen Inra
Jacquelin, S..
Les invasions biologiques offrent la possibilité d’appréhender des processus écologiques et évolutifs majeurs, se produisant à de larges échelles spatiales et temporelles. La génétique de l’invasion permet ainsi d’étudier les facteurs historiques et évolutifs favorisant l’expansion des espèces introduites. Avec l’aide de marqueurs microsatellites, nous avons analysé la diversité génétique et la structuration géographique de populations de deux insectes Hyménoptères exotiques dans les cédraies françaises: Megastigmus schimitscheki (en expansion géographique) et M. pinsapinis (distribution géographique stabilisée). Nous avons montré que ces deux espèces ont connu un goulot d’étranglement lors de leur introduction. Les données génétiques et historiques ont...

Biogeographic distribution of the Phytoseiidae 'Acari: Mesostigmata Inra
Tixier, M.S.; Kreiter, S.; de Moraes, G.J..
More than 1982 species in 90 genera were included in an analysis of the biogeography of the Phytoseiidae, a family of predatory mites. Seven biogeographic regions were taken into account: Nearctic, Neotropical, Ethiopian, West Palaearctic, East Palaearctic, Oriental, and Australasian. The number of species was particularly high in the Neotropical, Oriental, and West Palaearctic regions. These regions also present the highest levels of species endemism. The number of genera was quite similar in all regions except for the Neotropics, which also had a high level of endemism. The possible Gondwanian (Neotropical, Ethiopian, Australasian, and Oriental regions) origin of the Phytoseiidae, most probably in the Neotropics, and their possible radiation to Laurasia...

Cameraria ohridella, ravageur des marronniers d’Inde Inra
Augustin, S.; Guichard, S.; Courtin, C.; Lorme, P.; Roques, A..
La mineuse du marronnier Cameraria ohridella est une espèce invasive en Europe dont l’origine est inconnue. Sa dispersion est très rapide et cinq ans après son premier signalement aux frontières françaises, elle était présente en automne 2003 dans la plupart des départements. Son potentiel de développement est très important, et deux ou trois ans après son installation, elle peut, dès le début de mois de juillet, provoquer la chute des feuilles de son hôte préféré Aesculus hippocastanum. Les principaux résultats sur les recherches réalisées en Europe dans le cadre du contrat européen Controcam sont présentés.

Direct impacts of recent climate warming on insect populations Inra
Robinet, C.; Roques, A..
Effects of recent climate change have already been detected in many species, and, in particular, in insects. The present paper reviews the key impacts of global warming on insect development and dispersal. The effects of climate change appear to be much more complex than a simple linear response to an average increase in temperature. They can differ between seasons and bioclimatic regions. Earlier flight periods, enhanced winter survival and acceleration of development rates are the major insect responses. Differential response of insects and hosts to warming up might also lead to disruption of their phenological synchrony, but adaptive genetic processes are likely to quickly restore this synchrony. In a number of cases, warming results in removing or...

Dispersal polymorphism in an invasive forest pest affects its ability to establish Inra
Robinet, C.; Liebhold, A..
Given the increasing number of biological invasions, there is a crucial need toidentify life history traits that promote invasion. Invasiveness reflects capabilities for both establishment after introduction and spread following establishment. In this paper, we explore, via simulation, the interacting effects of dispersal and Allee effects on both invasion processes. Dispersal capability is a trait that has been widely recognized to facilitate invasions. However, dispersal dilutes local population densities in isolated populations and this could strengthen Allee effects, ultimately promoting extinction of invading populations. A spatiallyexplicit, stochastic individual-based model was used to simulate dispersal, mating, and growth in isolated, newly...

Disperse with the leaves and develop locally: a successful strategy for invasive leafminers? Inra
Gilbert, M; Castellana, F.; Svatos, A.; Augustin, S.; Grégoire, J.C.; IOCB, Institute of Organic Chemistry and Biochemistry of the ASCR, Department of Natural Products (CZE).
The very fast spread of the horse-chestnut leafminer Cameraria ohridella throughout Europe has been mainly attributed to a very high dispersal ability combined with wind or human passive transportationover long distances.However, the species effective dispersal characteristics remain to be better understood. Here we present data of experiments aiming to describe the decrease in population estimate as a function of distance to a population source. Firstly, we analysed the decrease in infestation level onhorse-chestnut trees along three transect avenues departing from population source located in green areas in Brussels. Secondly, we describe the decrease in catches of pheromone traps disposed along two transects departing from an isolated group of infested...

Dispersion in time and space affect mating success and Allee effects in invading gypsy moth populations Inra
Robinet, C.; Lance, D.R.; Thorpe, K.W.; Onufrieva, K.S.; Tobin, P.C.; Liebhold, A.M..
1.Understanding why invading populations sometimes fail to establish is of considerable relevance to the development of strategies for managing biological invasions.2.Newly arriving populations tend to be sparse and are often influenced by Allee effects. Mating failure is a typical cause of Allee effects in low-density insect populations, and dispersion of individuals in space and time can exacerbate mate-location failure in invading populations.3. Here we evaluate the relative importance of dispersal and sexual asynchrony as contributors to Allee effects in invading populations by adopting as a case study the gypsy moth (Lymantria dispar L.), an important insect defoliator for which considerable demographic information is available.4. We used...
