PM topographies of calcofluor and non-calcofluor treated Ae. aegypti larvae. PMs isolated from untreated larvae, calcofluor-treated larvae, Cry4Ba-treated larvae, and toxin and calcofluor co-fed larvae were analyzed with SEM (a). Tissue sections of treated larvae were stained with H&E and examined under a light microscope (b). Asterisks mark cracks along thick lines of PMs. Arrows indicate microvilli of the midgut epithelial cells and arrowheads present PM after staining with H&E. Abbreviations: L, lumen; EC, epithelial cells of the midgut
