Level of CYP4G19 Expression Is Associated with Pyrethroid Resistance in Blattella germanica
mRNA expression of the CYP4G19 gene of German cockroach after RNAi. (a) Semiquantitative RT-PCR analysis of CYP4G19 mRNA levels 28 days after dsRNA injection. Gel electrophoresis analysis of PCR products of actin (top band) and CYP4G19 genes (bottom band). (b) Relative mRNA levels after injection of dsRNA1, dsRNA2, dsRNA1+daRNA2, negative control dsRNA, and Ringer saline from day 2 to day 8.
