injection of dsrna into female a. aegypti mosquitos

Reverse approcci genetici si sono dimostrati estremamente utili per determinare quali geni di resistenza agli agenti patogeni sottostanti vettore nelle zanzare. Questo protocollo video illustra un metodo utilizzato dal laboratorio di James per iniettare dsRNA in femmine di A. aegypti zanzare, che ospitano il virus dengue. La tecnica per la calibrazione di aghi da iniezione, manipolare la configurazione di iniezione e iniezione di dsRNA nel torace è illustrato.
