Comparative expression analysis of GpSGHV odv-e66 and RNAi pathway genes in asymptomatically and symptomatically infected G. pallidipes flies. a Virus odv-e66 expression and b RNAi genes expression. Gene expression was quantified by RT-qPCR of the RNA extracted from whole fly bodies. Gene expression values were normalized to β–tubulin and transformed by the Box-Cox process (log(Expression). The RNAi pathways in which the genes may be involved are also shown. Open boxes = asymptomatic infected; grey boxes = symptomatic infected. Asterisks indicate the statistical significance: ***P < 0.001, **P < 0.01, *P < 0.05
