Fig. 2From: Growth inhibition of Spodoptera frugiperda larvae by camptothecin correlates with alteration of the structures and gene expression profiles of the midgutHistopathological and ultrastructural changes in the midgut of larvae fed on the diet supplemented with 1.0 and 5.0 µg/g CPT. A: Hematoxylin–eosin staining of the midgut obtained from larvae fed on a normal diet. B: Histopathological changes in the midgut dissected from larvae fed on the diet supplemented with 1.0 µg/g CPT. C: Histopathological changes of the midgut dissected from larvae fed on the diet supplemented with 5.0 µg/g CPT. D: The ultrastructure of the midgut obtained from larvae fed on normal diet. E: The ultrastructure of the midgut dissected from larvae fed on the diet supplemented with 1.0 µg/g CPT. F: The ultrastructure of the midgut dissected from larvae fed on the diet supplemented with 5.0 µg/g CPT. Me: midgut epithelium, Bm: basement membrane, L: lumen.
