Level of CYP4G19 Expression Is Associated with Pyrethroid Resistance in Blattella germanica by Guang-zhou Guo, Yi-jie Geng, Da-na Huang, Cai-fang Xue, Ren-li Zhang

“…A pyrethroid called “Jia Chong Qing” to prevent pests for a long time were found to be resistant to “Jia Chong Qing” with resistance index of 3.88 measured using RT-PCR and immunohistochemistry analysis showed that both CYP4G19 mRNA and CYP4G19 protein expression levels in the wild strain were substantially higher than that of a sensitive strain. dsRNA segments derived from the target gene CYP4G19 were prepared using in vitro transcription and were microinjected into abdomens of the wild strain. …”
