Figure 1

Micro-CT 3D rendered images with sagittal sections of fourth instar A. aegypti larvae. Mounted samples ready for scanning (a,b) and ethanol preserved larvae (c–e). Deformation (d) after exposition to B. thurigiensis var. israelensis (Bti) and empty space created, marked with red arrows (e). Control healthy larva (c,f,g). Larvae after different exposure times to Bti (d,e,h–k): 30 min (d,e,h), 1 h (i,j), 6 h (k). Details of the fore midgut epithelia and surrounding muscles (g,i). Note deformation (d) and empty space created (e), and the progressive cell lysis effect caused by Bti, which is observed in the form of openings in the midgut epithelia. Abdominal segments are numbered. Fd food, Fme fore midgut epithelia, Gc gastric caeca, Mu muscles, Op midgut epithelia openings, Pm peritrophic membrane.
