Relative expression levels of SinvCYP6B1, SinvCYP6A1, SinvCYP4C1, SinvCYP4G15, CYP4AB1, and CYP4AB2 in workers of the fire ant following treatment with fipronil at the LC₉₀ (0.56 μg mL⁻¹).

The relative expression levels of SinvCYP6B1, SinvCYP6A1, SinvCYP4C1, SinvCYP4G15, CYP4AB1, and CYP4AB2 in workers following treatment with fipronil at 0.56 μg mL⁻¹ at 12 and 24 h were determined by qRT-PCR. The experiments were repeated three times. The results are presented as the mean ± S.E. Significant differences within the same time point are indicated by different letters (P<0.05).
