Transmission electron micrographs of the epithelium of the anterior midgut from the alimentary canal of C. pipiens larvae. Normal alimentary canal of C. pipiens larvae showing the normal appearance of the nucleus with scattered chromatin, cytoplasm and cell organelles (A, B). Treatment with the pyrazole–pyridine derivative altered the nuclear structure leading to chromatin condensation and induced lysosomal activity in C. pipiens larvae (C, D). N (nucleus), and Cy (cytoplasm)
