Two copies of of a 31bp ban target sequence have been inserted into the 3'UTR of Avic\GFPEGFP.αTub84B.B.
Expression of AvicGFPEGFP.ban.αTub84B is ubiquitously expressed in the third instar larvae, but by the wandering third instar larvae expression is attenuated in muscles, epithelial cells and peripheral nervous system sensory neurons.
