Uninfected midgut (ME), and tracheole epithelial cells (TE) with basal lamina (BL) in between. Invaginations of the midgut epithelial cell plasma membrane (arrows) anchor the cell to the basal lamina. A tracheole (T), mitochondrion (M), and microtubules (arrowhead) can be seen in the tracheole epithelial cell. A muscle cell (MC) lies adjacent to the tracheole epithelial cell. Electron micrograph. Scale bar = 1 μm.
