Transmission electron micrographs of the epithelium of the gastric caecum from the alimentary canal of C. pipiens larvae. Normal alimentary canal of C. pipiens larvae showing the normal appearance of the nucleus, cytoplasm and microvilli (A, B). Treatment with the pyrazole–pyridine derivative (PPD) altered the appearance of the cytoplasmic components and induced serious damage in the microvilli in C. pipiens larvae (C, D). N (nucleus), MV (microvilli), and Cy (cytoplasm)
