Fig. 2. Transmission electron micrographs of thin sections in other organs of 1st instar nymphs of D. citri. A & B. The esophagus (A) and tracheal cells (B) of a pre-molting nymph; bl, basal lamina; ep, epithelial cells; nc, new cuticle; nt, new taenidia; nu, nucleus; oc, old cuticle, ot, old taenidia. C. Part of the filter chamber showing the chamber wall (cw), anterior midgut (amg) and posterior midgut (pmg); double arrows indicate closely apposed basal lamina of the anterior and posterior midgut; aml, anterior midgut lumen; mv, microvilli; pml, posterior midgut lumen. D. Bacteriocyte cell in the bacteriome with a large nucleus (nu) and various shaped electron-dense bacterial cells (ed). E. Another part of the bacteriome with 2 types of bacterial cells: electron-dense (ed) and electron-lucent (el).
