(B) The abdominal pericardial cells flanking the heart of adult flies (of all ages) showed intense staining, pc, pericardial cell; h, heart. (C) Whole mount of reproductive system and lower digestive system from a 3-5-day-old male. Intense staining is found in the ejaculatory pump and in two regions of the ventriculus. (D) Whole mount of ejaculatory pump from a 1-2-day-old male has low levels of enzyme activity. No staining was found elsewhere, including the ejaculatory duct, testes, or rectum, a, anus; ed, ejaculatory duct; ep, ejaculatory pump; r, rectum; t, testes. (E) Whole mount of the female reproductive system from a 3-5-day-old fly shows /3-galactosidase activity in the calyx and pedicel of the ovary (arrow) and in the uterus (F). co, common oviduct; o, ovary; u, Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Lillie, Frank Rattray, 1870-1947; Moore, Carl Richard, 1892-; Redfield, Alfred Clarence, 1890-; Marine Biological Laboratory (Woods Hole, Mass. ); Marine Biological Laboratory (Woods Hole, Mass. ).
