(A) General view showing damaged microvilli (MV), Nucleus (N), mitochondria (arrowhead) and enlarged basal labyrinth (BL) and muscle (M). (B) Midgut lumen showing cell debris similar to mitochondria (arrows) and rough endoplasmic reticulum (arrowheads). (C) Basal cell region showing big lipid droplets (asterisks) and enlarged basal labyrinth (BL). (D) Perinuclear cytoplasm with autophagic vacuoles (arrows), lipid droplet (asterisk) and damaged mitochondria (arrowheads).
