Fig. 4From: CPR63 promotes pyrethroid resistance by increasing cuticle thickness in Culex pipiens pallensSEM analysis of cuticle thickness. Measurements were made at 23 different points per individual, allowing for the calculation of mean cuticle thickness. Results are shown as the mean ± SD; n = the number of measurements carried out on each group of 11 mosquitoes. **p = 0.0011Back to article page
