These structures, called “tubenets,” allow symbiotic bacteria in cereal weevils to increase the surface area of exchange with the host cell to recover an essential nutrient: sugar.

A huge congratulations to the whole team and our collaborators! 2/5

📣 #OurLastPaper is out! And it's a major breakthrough that we're publishing in @cp-cell.bsky.social l: we've discovered architect bacteria that build complex structures to feed themselves better!

The jury included Peter Mergaert, Sébastien Duperron & Olivier Duron. BF2i warmly congratulates Hugo on this great achievement and the high quality of his work 👏! Check out part of his PhD work 👉 dx.doi.org/10.1007/s103... and his CV HAL 👉 cv.hal.science/hugo-terrasson

🎓 🎈Congratulations to Hugo Terrasson, who has successfully defended his PhD! Supervised by Pedro Da Silva, Federica Calevro, & Mélanie Ribeiro Lopes, his thesis explored the role of bacteriocyte-specific cysteine-rich peptides in the pea aphid symbiosis.

👏 Congratulations to Sylvain Benhamou and Mélanie Ribeiro Lopes, who gave brilliant presentations on their work!

📅 From October 13 to 17, 2025, the 12th edition of the International Symposium on Aphids (ISA12) took place in PyeongChang, South Korea. It was a great opportunity to discuss and share our research findings with experts from around the world, exploring all aspects of #aphid life.

Thanks @insa-lyon.fr for coordinating our activity, specially Guillemette & Ludivine. Thanks Zahar & Audrey from @umr5240-map.bsky.social along with @ritarebollo.bsky.social and Jesus from BF2i for participating!

🧑‍🔬 The fête de la science Symbiosis walk was a success! Thank you all the school and families that have shared a bit of their curiosity with us 🪲🦠

👏 During a ceremony held at @insa-lyon.fr on October 10, 2025, Federica Calevro, Director of @inrae-umr-bf2i.bsky.social 🔬, was named "Chevalier de l'ordre des Palmes académiques" 🏅 by Frédéric Fotiadu, Director of INSA Lyon. Congratulations Fede!

Yesterday @ritarebollo.bsky.social brilliantly obtained her Habilitation à Diriger des Recherches in front of a jury composed of L. Teysset, C. Vitte, F. Hommais, N. Nègre, Z. Haichar & N. Kremer. A summary of 20 years of research in 3 labs & 2 countries with a common theme: interactions! 👏

Hi! We are looking for a PhD to work on the cross talk between transposable elements, insects and intracellular bacteria on the bioinformatics side. The PhD would be supervised by @mariefablet.bsky.social and myself along with @nicolasparisot.bsky.social Deadline December 2025! Please share! #tesky

From September 10 to 12, the 23rd conference on Computational Methods in Systems Biology (cmsb2025.sciencesconf.org) was held at Université Lyon 1 & @cnrs.fr. Congratulations to Sergio Peignier and Erwan Cruché, who gave brilliant presentations on their research 👏

📣 #OurLastPaper is out! In collaboration with the IMP lab and the LBBE lab, this work focuses on exploiting the synergy of essential oils to enhance repellency against sap-sucking insects.
