Effects on key genes in the chitin biosynthesis pathway after specific RNAi in last-instar larvae at 48 and 72 h. The levels of these genes relative to the Tcβ-actin mRNA level were measured via qRT-PCR. a mRNA levels of glycogen synthase (GS) and glycogen phosphorylase (GP). b mRNA levels of two hexokinases (HK1 and HK2). c mRNA levels of three chitin synthases (CHS1a, CHS1b and CHS2)
