Relative quantification of acetylcholinesterase transcript 2 (AChE2) expression levels in ticks. Tick larvae from different strains and isolates subjected to RNA extraction and qPCR, and the results were subsequently converted to REU and compared against those of the susceptible strain, which was considered 1 REU.

Tick sample	AChE2 REU
Susceptible	1 ± 0.3
Resistant	13.07 ± 3.49**
Isolate C1	8.52 ± 1.35*
Isolate C2	79.59 ± 15*

*p < 0.0001; **p < 0.0005.
