Diagram of experimental design. Two life stages (adults and larve) were tested in each of the 5 transgenic lines, 4 of them harbouring heterozygous integration of the tTAV constructs (het) and one homozygous (hom). All differential gene expression was assessed between tetracycline ON (tet-ON) and tetracycline OFF (tet-OFF) conditions (double-ended arrows) only within each single strain and life stage to ensure that observed effects are due to different treatments and not different genetic backgrounds
