C'est pas sorcier - Season 1 Episode 305 Un moustique, ça trompe énormément
Cet été, vous ne pourrez pas leur échapper ! C'est à l'odeur et à la chaleur de votre peau, ainsi qu'au CO2 que vous dégagerez en respirant, que les moustiques vous repèreront. Il faut dire qu'ils sont équipés d'un remarquable arsenal de détection : une paire d'yeux à facettes, des antennes dont ils se servent comme un véritable nez, et surtout, une trompe. Pas celle d'un éléphant… mais plutôt une sorte de paille qu'ils plongent dans la peau de leur victime pour en pomper le sang. Pourquoi ça démange, une piqûre de moustique ? Pourquoi les femelles moustiques ont-elles besoin de sang alors que les mâles se régalent du nectar des fleurs ? Comment certains moustiques sont-ils devenus résistants aux insecticides ? Et pourquoi les moustiques tropicaux transmettent-ils des maladies graves, comme le paludisme ou la fièvre jaune ?
