  Protéger les collections végétales des virus

  06/06/2012 Sophie Della Mussia

  Le projet SafePGR (Towards Safer Plant Genetic Resources through improved viral diagnostics) du réseau Net-Biome a organisé son atelier de lancement du 26 au 28 mars 2012 à Madère. Ce projet associe les Centres de Ressources Biologiques (CRB) de l'Inra, du Cirad en Guadeloupe et à la Réunion, des Universités des Açores et de Madère, et les équipes de virologie de l'Inra et du Cirad de Bordeaux et Montpellier. Il a pour objectif de sécuriser la conservation et les échanges des ressources végétales conservées dans les CRB par la mise au point et la mise en œuvre de techniques de diagnostic virologique de nouvelle génération.

  Bees disoriented by low-level insecticide doses

  26/06/2012 Quentin Ceuppens

  For the first time, an interdisciplinary French research team has found a link betweenbee population decline and an insecticide caused, not directly by insecticidetoxicity, but by disorientating bees and reducing their ability to return tothe hive. To carry out the study, researchers attached RFID microchips to morethan 650 bees. Foraging bees previously fed sugar water with a very low dose of thiamethoxam in a lab were found to have a significant incidence of failing toreturn to the hive. Thiamethoxam is an insecticide from the neonicotinoidfamily used to protect crops from certain pests, primarily through seedcoating. A simulation based on these results suggests that insecticides mayhave a substantial impact on bee colonies. The results were published in thejournal Science on 29 March 2012.

  A new upland rice variety for the highlands of Madagascar

  05/11/2014 Quentin Ceuppens

  A new upland rice variety is now available to growers in the highlands of Madagascar. The variety is the fruit of a partnership between FOFIFA and CIRAD, and is tailored to the agro-climatic conditions in the region. In particular, it is tolerant of the cold temperatures over 1200 m above sea level.
