Introduction
I'm a taxonomist and an evolutionary biologist working on insects. My main group of interest are chalcid wasps, including figwasps and wasps used in biological control, i.e. Trichogramma (ANR TRIptic). I'm involved in projects dealing with phylogenomics of Chalcidoidea (Agaonidae, Pteromalidae and Chalcididae)(NSF); Carabidae; Sphingid and Saturniid moths (ANR SPHINX) as well as other pests. I'm also studying communities of vectors that transmit Xylella fastidiosa to plants in Europe (XF-Actors). Finally, I sampled and identified fig trees (Ficus, Moraceae) over the last 30 years. I have photographed +500 species in the wild and plan to produce soon an illustrated book on the Ficus of the world.

Article
Full-text available
Despite many attempts in the Sanger sequencing era, the phylogeny of fig trees remains unresolved, which limits our ability to analyze the evolution of key traits that may have contributed to their evolutionary and ecological success. We used restriction-site-associated DNA sequencing (c. 420 kb) and 102 morphological characters to elucidate the re...

Until now, the potential of NGS has been seldom realised for the construction of barcode reference libraries. Using a two-step PCR approach and MiSeq sequencing, we tested a cost-effective method and developed a custom workflow to simultaneously sequence multiple markers ( COI, Cytb and EF , altogether 2kb) from hundreds of specimens. Interestingly...

We sampled ca 2500 specimens of Philaenus spumarius (Hemiptera: Aphrophoridae) throughout Corsica without a priori knowledge on the presence of symptoms on plants. We screened 448 specimens for the presence of Xylella fastidiosa (Xf) using qPCR and a custom nested PCR. qPCR appeared versatile and under-estimated the prevalence of Xf. Nested PCR sho...
Article
Full-text available
Target enrichment is increasingly used for genotyping of plant and animal species or to better understand the evolutionary history of important lineages through the inference of statistically robust phylogenies. Limitations to routine target enrichment are both the complexity of current protocols and low input DNA quantity. Thus, working with tiny...

Recent technical advances combined with novel computational approaches promised the acceleration of our understanding of the tree of life. However, when it comes to hyperdiverse and poorly known groups of invertebrates, studies are still scarce. As published phylogenies will be rarely challenged by future taxonomists, careful attention must be paid...
Article
The bacterium Xylella fastidiosa (Xf) is a major threat to European agriculture and notably to the olive and Citrus industry. It is transmitted by xylem-feeding insects, whose plant-feeding preferences still require investigation in European agroecosystems. Here we studied olive and clementine groves of the oriental plain of Corsica. Insect-vegetat...

A bstract Wild silkmoths (Saturniidae) are one of the most emblematic and most studied families of moths. Yet, the absence of a robust phylogenetic framework based on a comprehensive taxonomic sampling impedes our understanding of their evolutionary history. We analyzed 1,024 ultraconserved elements (UCEs) and their flanking regions to infer the re...
Article
Planidia are free-living, mobile first-instar larvae that are notable in their ability to transition across different larval stages of their host, and for completing their development on the host prepupa as ectoparasitoids, effectively acting as larval-pupal external koinobionts. Chalcidoid taxa with a planidium form a monophyletic group, the plani...

Evaluer le risque que représente un bioagresseur est un élément primordial pour mettre en place des mesures d’épidémiosurveillance et de gestion appropriées. A travers le cas de Xylella fastidiosa, nous montrons que cette évaluation nécessite une bonne connaissance du bioagresseur et de ses vecteurs éventuels, des techniques de détection fiables et...
Article
Full-text available
Biotic invasion in mutualistic communities is of particular interest due to the possible establishment of new relationships with native species. Ficus species are widely cultivated as ornamental plants, and they host specific communities of chalcid wasps that are strictly associated with the fig inflorescences. Some introduced fig species are capab...

A major obstacle to high-throughput genotyping of microhymenoptera is their small size. As species are difficult to discriminate, and because complexes may exist, the sequencing of a pool of specimens is hazardous. Thus, one should be able to sequence pangenomic markers (e.g., RADtags) from a single specimen. To date, whole genome amplification (WG...

Enriching subsets of the genome prior to sequencing allows focusing effort on regions that are relevant to answer specific questions. As experimental design can be adapted to sequence many samples simultaneously, using such approach also contributes to reduce cost. In the field of ecology and evolution, target enrichment is increasingly used for ge...
Conference Paper
Full-text available
Chalcid wasps are one of the most diverse lineages of Hymenoptera also highly disparate in terms of morphologies and biologies. The evolutionary relationships among Chalcidoidea have remained virtually untested. No multilocus molecular phylogeny has been deployed heretofore towards assessing the basal tree topology with appropriate sampling. Here w...
