injection of dsrna into female a. aegypti mosquitos

Inverse des approches génétiques se sont avérées extrêmement utiles pour déterminer quels gènes de résistance sous-tendent à des agents pathogènes vecteurs de moustiques. Ce protocole vidéo illustre une méthode utilisée par le laboratoire de James à injecter dans les ARNdb femelles moustiques A. aegypti, qui abritent le virus de la dengue. La technique pour l&#39;étalonnage des aiguilles d&#39;injection, de manipuler la configuration d&#39;injection, et l&#39;injection ARNdb dans le thorax est illustré.
