Les chercheurs ont montr\u00e9 que deux esp\u00e8ces de ravageurs du ma\u00efs du Kenya, Busseola fusca<\/em> et Chilo partellus<\/em> ont des comportements alimentaires diff\u00e9rents selon la quantit\u00e9 de silice dans les feuilles de la plante. Or celle-ci varie avec la temp\u00e9rature et donc avec l’altitude. Ils font donc l’hypoth\u00e8se que le changement climatique pourrait modifier la r\u00e9partition des deux esp\u00e8ces d’insectes ravageurs.<\/p>\n
