Research interests

I’m an ecologist interested on the interactions between plants and their associated insect communities (herbivores, parasitoids etc.) and pathogens. During my PhD, I focused on PLANT-INSECT interactions on the context of PLANT INVASION in order to understand some of the key factors underlying the invasive ability of certain plant species. During my postdoc, I focused on PLANT-FUNGI interactions to study multiple infections and within-host competition of the anther-smut fungi, responsible for castrating its host.

One of my research interests relates to insect behaviour and to the mechanisms underlying host selection and acceptation by Lepidoptera (e.g. moths and butterflies) and Hymenoptera parasitic wasps. I’m interested on CHEMICAL ECOLOGY of plant-insect interactions, particularly on the cues used by insects during host searching behaviour (e.g. plant volatiles, contact cues). This knowledge is essential to evaluate the efficiency of weed and crop pest BIOLOGICAL CONTROL programs.

Since 2018, I am conducting the risk assessment for non-target species of a stemborer parasitoid to evaluate the feasibility of using a Cotesia parasitoid as a new biological control agent against the Mediterranean corn borer (ANR project COTEBIO: https://tinyurl.com/58m4adjr). Currently, as part of the PHENOFORE project funded by SEMAE (https://tinyurl.com/sykup5tn), I am studying the oviposition behavior of two maize pests, the Mediterranean and the European corn borer, according to different corn varieties, and the factors underlying host plant selection (eg plant volatiles). The foliar consumption rate of the larvae of these pests is also studied in order to correlate the adult choice with the larval performance.
