Ultrastructure of leg and abdominal cuticles from CpCHSA-deficient adults. NC or siCHSA was injected into 0- to 1-h pupae (300 ng per pupae). a The ultrastructure of adults at 24 h PE was analyzed using TEM. Insects were injected with NC or siCHSA. The red arrow indicates the leg and abdomen of the adult. b–c Between the NC and siCHSA groups, there were differences in the thickness and structure of the abdominal cuticle (b) and differences in the leg cuticle (c).
