Scientific Discovery Insects recycle their symbiotic bacteria when their earnings lapse.

Insects have developed a molecular strategy that allows them to adjust the number of beneficial bacteria to their physiological needs, and optimize the cost / benefit ratio of the symbiosis. They "learned" during their evolution to recycle their symbiotic bacteria, and they do it properly!This is what researchers have recently shown INSA and INRA in an article published Sept. 18 in Current Biology. These work on grain weevil open the door to new ways to fight against this parasite. ---------------------------------------Références :On Line : Insects Recycle Endosymbionts when the Benefit Is Over, Current Biology 24 6 Octobre 2014.Aurélien Vigneron, Florent Masson, Agnès Vallier, Séverine Balmand, Marjolaine Rey, Carole Vincent-Monégat, Emre Aksoy, Etienne Aubailly-Giraud, Anna Zaidman-Rémy, and Abdelaziz HeddiBiologie Fonctionnelle Insectes et Interactions, UMR203 BF2I, INRA, INSA-Lyon, Université de Lyon, 69621 Villeurbanne, FranceAdresse actuelle : Department of Epidemiology of Microbial Diseases, Yale School of Public Health, New Haven, CT 06520-8034, USA.
