Midgut region	Mean ± SEM (n)
Anterior	5.9 ± 0.1 (14)a
Middle	2.1 ± 0.1 (14)b
Posterior	8.3 ± 0.2 (14)c

Different letters indicate statistically significant differences between groups (mean ± SEM, number of replicates in parentheses. ANOVA test followed by Tukey’s test. ANOVA p-value < 0.001, Tukey’s test p-values: Middle vs. Anterior p < 0.001, Posterior vs. Anterior p < 0.001, Posterior vs. Middle p < 0.001).
