Fat body cells, 620 ppm of BA. Note wide space between cells (b, c, white arrows). Not homogenous (a–c, asterisks) and fusing fat droplets (F; a, c, black arrowheads). Advanced vacuolization of mitochondria (M; d, white arrowheads). Myelinated figures (a, b, caret symbol) and pyknosis (a, black arrow). Vacuolization of cytoplasm (b–d). Nuclei (N) show invaginations (a–c), but nuclear envelope (NE) is not swollen
