Ultrastructure of mesocuticle and endocuticle from TcCHT7-deficient adults.

<p>Ultrastructure of rigid elytral dorsal cuticle from 1 d-old adults (A and B) and 3 d-old adults (C and D) that had been injected with dsRNA (200 ng per insect; n = 30) for <i>TcVer</i> (A and C) and <i>TcCHT7</i> (B and D) into the late instar larvae was analyzed by TEM. EN, envelope; EP, epicuticle; EXO, exocuticle; PCF, pore canal fiber; APMP, apical plasma membrane protrusion; MESO, mesocuticle; ENDO, endocuticle; PC, pore canal. Scale bar = 2 μm.
