Dynamics of Sodalis copy number in G. m. morsitans adult flies maintained under laboratory colony conditions. Four males and four females were tested at each time point to estimate the Sodalis copy number using qPCR. Normalized qPCR data were transformed (λ = − 0.2) to best fit the normal distribution. * shows a significant difference between treatments at different levels (Tukey HSD at the 95% family wise confidence level), (* (P < 0.05 level), ** (P < 0.001), *** (P < 0.0001))
