title: [Histology and cytology of tergal gland of Leucophaea maderea and its development during sexual maturation of the male].
abstract: The tergal gland of the adult male Leucophaea maderea is a tegumentary specialization of the second abdominal segment. This gland is involved in the conditioning of the female to mating. Several types of hypodermal cells may be recognized among which are numerous glandular cells full of gycoproteic granules. Each of these cells is provided with a axial tubular crypt through which passes a cuticular canal collecting the secretion products. All the canals open independently at the surface of the cuticle and the substance deposited there is a mixture of proteins and acid mucosubstances. Morphological differentiation is finished just after the moult, but functional differentiation starts with the histological and cytological restructuring of the epidermis, particularly the elaboration, growth and maturation of numerous granules in the glandular cells. This differentiation which occurs mainly during the first week of imaginal life is in synchronism with sexual maturation.
