“…The persistent nature of the droplets and globules, despite the preparative procedures, lends weight to the argument that the secretion from the brood pouch is something other than just water. The occurrence of similar ducts with droplets of secreted material at their openings has been previously described by Crossley and Waterhouse [15] in the pheromone secretory glands of the male scorpion-fly Harpobittacus australis.…”

The morphology of the brood sac in the ovoviviparous cockroaches Byrsotria fumigata and Gromphadorhina portentosa was examined by light and scanning electron microscopy. Projecting from the lumenal surface of the brood sac are numerous papillae, all of which have pores distributed over their apices. The pores represent the external openings of ducts which pass from secretory cells lying beneath the cuticularised lumenal lining. Evidence is presented which suggests that secretory material is transported via the papillae to the lumen of the brood sac and hence could provide the embryo with a source of nutriment. Striking similarities with the situation found in the viviparous cockroach, Diploptera punctata, are discussed.

“…Whether the glandular.units exist singly, as is true for the dermal glands of Rhodnius (Lai-Fook 1970), the dermal glands of Tenebrio (Delachambre 1973), the Verson's glands of Calpodes (Lai-Fook 1973), and the tegumentary glands of the myriapod Scutigeralla (Juberthie-Jupeau 1975), or are assembled in a larger gland, as is true for the Brindley's glands of Rhodnius, the pheromonesecreting gland of the male scorpion-fly, Harpobittacus (Crossley and Waterhouse 1969), the terpene-producing glands of the large walking stick Anisomorpha (Happ et al 1966), the pygidial glands of the beetle Bledius mandibularis (Happ and Happ 1973), the lateral scent glands of the green vegetable bug Nezara viridulu (Filshie and Waterhouse 1968), and the collaterial glands of Periplaneta (Mercer and Brunet 1959), they have two features in common. First, they have a secretory cell with a secretory surface having microvilli of varying length and density and second, they have a cuticular duct leading either to the surface,of the insect or the lumen of a larger gland (Lai-Fook 1970).…”

A detailed light and electron microscopic study of the Brindley's glands of adult Rhodnius prolixus has confirmed the presence of type B glandular units similar to those described for the dermal glands of Rhodnius and has identified the second type A glandular unit, also composed of secretory apparatus, saccule, and duct, but outnumbered approximately 18:1 by the type B units. Similarities and differences between type A and type B glandular units are described and the possible functional significance of the two types of unit is discussed.

“…Similar dermal glands are known from many insects (and may be ubiquitous), such as Dictoyptera (e.g. Brossut and Sreng 1980;Quennedey 1969), Mecoptera (Crossley and Waterhouse 1969), Hemiptera (e.g. Farine 1987Farine , 1988, and Coleoptera (e.g.…”

Morphology of the pronotal compound glands in Tritoma bipustulata (Coleoptera: Erotylidae)

Members of the cucujiform family Erotylidae possess a whole arsenal of compound integumentary glands. Structural details of the glands of the pronotum of Tritoma bipustulata and Triplax scutellaris are provided for the first time. These glands, which open in the posterior and anterior pronotal corners, bear, upon a long, usually unbranched excretory duct, numerous identical gland units, each comprising a central cuticular canal surrounded by a proximal canal cell and a distal secretory cell. The canal cell forms a lateral appendix filled with a filamentous mass probably consisting of cuticle, and the cuticle inside the secretory cell is strongly spongiose-both structural features previously not known for compound glands of beetles. Additional data are provided for compound glands of the prosternal process and for simple (dermal) glands of the pronotum. A combined defense plus anti-microbial function of the compound glands is tentatively proposed.
