Relative gene expression of the V-ATPase in C. septempunctata under dietary RNAi treatments. The relative gene expression levels of V-ATPase were normalized to the most suited non-rRNA (A, Actin and Tubulin) and the least suited (B, NADH and ArgK) reference genes, respectively. For dietary RNAi, ladybeetle larvae were exposed to an artificial diet containing 15% sugar solution and 4.0 μg/μl dsRNAs for 2 days (see Materials and Methods for details). The transcript levels of V-ATPase in newly emerged (0 day) untreated larvae were set to 1, and the relative mRNA expression levels in dsRNA-fed larvae were determined with respect to the controls. Values are means ± SE. Different letters indicate significant differences between the treatments and controls (P < 0.05).
