Dietary delivery of MpNav dsRNA alters MpNav expression in M. persicae. Relative abundances of MpNav H1 gene transcripts, as determined by qRT-PCR of cDNA made from total RNA isolated from whole body 1 to 7 days after the indicated dietary treatments of M. persicae. Data represent the mean ± SEM of three independent experiments. MpNav mRNA was normalized with Actin as an endogenous control. Treatment was compared with controls using ANOVA (Tukey Kramer multiple comparison, p < 0.05). Symbols ns, ** and *** indicates non-significant, P < 0.01 and P < 0.005 respectively.
