✦ Synopsis

Primordia of organs of the male reproductive system develop abnormally in response to near lethal temperatures when thermal pressure is applied at a time of cellular differentiation during embryogeny and postembryogeny. This paper is concerned primarily with the thermally induced imaginal deformities effected during embryogeny. All parts of the masculine system may be affected except the gonads. Part or all of the tract and accessory glands may be deleted by regulating the time and duration of exposure to critical temperatures. The critical period for the inhibition of development of the reproductive tract in the embryo occurs primarily during the fourth and fifth days of ontogeny. Morphogenesis of imaginal female organs was unaffected by excessive embryogenic temperatures in either genetic females or genetic males. Certain primordia of larval parts developed abnormally when embryos were subjected to temperatures somewhat above those permitting survival beyond the first larval instar.
