RNA interference in mosquito: understanding immune responses, double-stranded RNA delivery systems and potential applications in vector control.

abstract：:Reverse chemical ecology based on insect functional odorant binding proteins has been extensively studied to screen behaviourally active compounds, whereas chemosensory proteins (CSPs), which are reportedly involved in olfactory chemical reception and could serve as molecular targets remain unclear.
