Thirty days after the start of the experiment: (C) females showing moderate vacuolation and (D) males with mild to moderate vacuolation. Forty-five days after the start of the experiment: (E) female presenting mild to moderate vacuolation and (F) male showing mild vacuolation. Post-depuration: (G) female liver with mild vacuolation and (H) male with minimal vacuolation (scale bar = 100 µm, H–E).
