Introduction
As a highly motivated researcher, I worked on several bark beetle species and studied their coevolution with predators, particularly from the point of view of their chemical communication. I also investigated the bacterial and fungal symbionts associated with these insects, and their potential influence on the tritrophic relationship tree-bark beetle-natural enemies. I am now looking for new challenges in ecology, symbioses and chemical ecology.

  • Using a multidisciplinary approach (Ecology-Chemistry-Microbiology-Genetics), I study the association of a bark beetle and its specific predator, with emphasis on their microbial symbionts and the chemical signals regulating the predator’s oviposition

Article
Full-text available
FULL TEXT FREELY AVAILABLE ON http://rdcu.be/uYSw - Examples of totally specific predators are rare, and the mechanisms underlying this specificity are often poorly understood. In Eurasia, the Monotomid beetle Rhizophagus grandis is found only in the galleries of its prey, the bark beetle Dendroctonus micans. The specificity of R. grandis relies on...
Thesis
FULL TEXT AVAILABLE ON http://hdl.handle.net/2013/ULB-DIPOT:oai:dipot.ulb.ac.be:2013/232990 - Rhizophagus grandis is one of the rare examples of totally specific predators: it only preys upon the bark beetle Dendroctonus micans in its native range (Europe and Asia). In the course of coevolution in such predator-prey systems, prey are selected for a...

Full-text available
Bark beetles (Curculionidae: Scolytinae) are one of the most species-rich herbivorous insect groups with many shifts in ecology and host-plant use, which may be mediated by their bacterial and fungal symbionts. While symbionts are well studied in economically important, tree-killing species, little is known about parasitic species whose broods deve...
Article
The weakened or suppressed hosts targeted by tree-killing conifer bark beetles during endemic phases are considered to be poorly defended and available to several competing species. Hosts face trade-offs in the allocation of resources in growth and reproduction or in defense, and the defense/resources status varies with time after host’s death or w...
Article
There is an evolutionary trade-off between the resources that a species invests in dispersal versus those invested in reproduction. For many insects, reproductive success in patchily-distributed species can be improved by sibling-mating. In many cases, such strategies correspond to sexual dimorphism, with males-whose reproductive activities can tak...
Thesis
FULL TEXT AVAILABLE ON http://hdl.handle.net/2013/ULB-DIPOT:oai:dipot.ulb.ac.be:2013/113956 - Dendroctonus micans is a Eurasian bark beetle. Adults and larvae attack conifers and feed on the phloem. The main regulation factor of their populations is the highly specific predator Rhizophagus grandis which has a well-developed searching behaviour. It...
