Emmanuelle Jacquin-Joly recognised for her red-palm-weevil research

On 14 March 2022 in Abu Dhabi, Emmanuelle Jacquin-Joly, an INRAE researcher, received the Khalifa International Award for Date Palm and Agricultural Innovation. This award recognises her collaborative research efforts to identify a red palm weevil olfactory receptor. This work has opened the door to the development, in collaboration with all her British, Italian, French and Saudi colleagues, of a "bio-inspired artificial nose" for the early detection of this very damaging palm tree pest.

Emmanuelle Jacquin-Joly, INRAE researcher at the Institute of Ecology and Environmental Sciences of Paris (iEES-Paris), received an award for her work on the red palm weevil (Rhynchophorus ferrugineus), the main palm tree pest, during the 7th International Date Palm Conference in Abu Dhabi. This international individual award, granted as part of the Khalifa International Award for Date Palm and Agricultural Innovation in the "Distinguished Innovative Studies and Modern Technology" category, is given each year to people working in the areas of science, industry, or government services or to NGOs that have had a significant impact on date palms and/or the region's agricultural sector via a major innovation.

Emmanuelle Jacquin-Joly won the award for her collaborative research to identify a red palm weevil olfactory receptor involved in detecting and recognising the insect's aggregation pheromone. This receptor will now make it possible to develop a biosensor or "bio-inspired artificial nose" that could signal the presence of this pest at a very early stage. The artificial nose detects aggregation pheromones emitted by the weevil when it alights on palm trees. "They emit this pheromone to find each other on palm trees to then feed, mate and lay their eggs," explained the INRAE scientist. The work done by Emmanuelle Jacquin-Joly and her team focussed on identifying and characterising the right receptor to be included in the artificial nose. 

This research was carried out as part of an international consortium involving Great Britain, Saudi Arabia, Italy and France, together with financial support from the King Abdullah University for Science and Technology (KAUST, Saudi Arabia) and the French Investments for the Future "Growing and Protecting Crops Differently" priority research programme (Pherosensor Project). In fact, for Emmanuelle Jacquin-Joly, "While this is an individual award, it recognises the consortium's work as a whole". Initial tests of the artificial nose, carried out first in a laboratory and then in the field in Saudi Arabia, have been promising. It will be a valuable decision-making support tool for combatting the major threat the red palm weevil poses to many countries, including France.

Biocontrol target for the red palm weevil revealed

Throughout the world, palm trees are of tremendous importance economically and socio-culturally as well as in terms of tourism and heritage. Of all the pests that infect them, the red palm weevil, Rhynchophorus ferrugineus, remains their main enemy. A quarantine pest, it causes enormous economic losses in palm tree crops. Researchers from INRAE and Sorbonne University, in collaboration with research teams in Saudi Arabia and the United Kingdom, have identified the first pheromone receptor for the red palm weevil, thereby opening the way to new methods for disrupting aggregation and reproduction and for devising early detection methods by developing biosensors based on that receptor. This research work was published in the 9 March 2021 issue of Molecular Ecology.

A new target in the fight against the cotton leafworm

PRESS RELEASE - In collaboration with scientists in China, researchers at INRAE and Sorbonne University have identified a new lineage of pheromone receptors in the cotton leafworm (Spodoptera littoralis), a polyphagous pest moth. This work was published in eLife on December 3, 2019. The study highlights that sex pheromone receptors have evolved more than once in the order Lepidoptera and describes a new target for biocontrol efforts.
