a, b Schematic representation of the impact of CYP6P9a genotypes on egg-laying success with odd ratio (OR). c Number of eggs laid by the CYP6P9a-RR, CYP6P9a-RS and CYP6P9a-SS genotypes. d Number of larvae generated by females from each genotype. e Comparison of the mean number of eggs laid and hatching rate between the three genotypes. Median value with interquartile range is shown for each distribution. Dotted line indicates females for which at least 50 eggs or larvae were obtained. Difference between genotypes was not significant in term of eggs laying by Kruskal–Wallis non-parametric test whereas the number of larvae produced, and the hatch rate differed significantly. ***Significant difference at p < 0.001; *significant difference at P < 0.05; NS not significant.
