TLDR
The spermathecal accessory gland of female Tenebrio molitor is examined by histochemicai and electron microscopical techniques and the product is a glycoprotein.Abstract:
The spermathecal accessory gland of female Tenebrio molitor is examined by histochemicai and electron microscopical techniques. Immediately after ecdysis of the female, neither Golgi regions nor the endoplasmic reticulum of the secretory cells are well developed. In two days' time, the cytoplasm is rich in rough endoplasmic reticulum and the Golgi areas are expanded. Membrane-bound droplets of secretion move from the Golgi zone to a central cavity, formed by the invaginated plasma membrane of this cell. As the secretion accumulates this cavity swells until the fourth day after ecdysis when the females first mate. An efferent cuticular ductule, ensheathed in a ductulecarrying cell, carries the product to the main axial duct of the tubular gland. By histochemical criteria, the product is a glycoprotein.read more

Fine structure of insect epidermal glands
Charles Noirot,André Quennedey +1 more
TL;DR: The present review is devoted to the exocrine glands derived from epidermis; glands associated with the preoral cavity (mandibular, salivary, etc) and genital apparatus are not dealt with except for the sake of comparison.

TL;DR: This review takes an integrative approach to sexual selection in Tribolium flour beetles (Coleoptera: Tenebrionidae), a particularly well‐studied and economically important model organism.

Comparative anatomy of the defensive glands, ovipositors and female genital tubes of tenebrionid beetles (Coleoptera)
TL;DR: Several major lines of tenebrionid evolution become apparent, including the lagriines and their allies, probably including the adeliines, pycnocerines and goniaderines; (2) the diaperines andTheir allies; (3) the coelometopines, cnodalonines, strongyliines, talanines and Their allies; and (4) the tene brionines, opatrines, helopines and toxic

Fine structure of the prothoracic mycangium, a chamber for the culture of symbiotic fungi, in the southern pine beetle, Dendroctonus frontalis.
TL;DR: The ultrastructure of the prothoracic mycangium of female Dendroctonus frontalis is examined, which consists of a cuticular invagination within which symbiotic fungi are cultured by the pine beetle and transported to new host trees.

Comparative morphology of the internal reproductive system of the Chrysomelidae (Coleoptera)
TL;DR: A great number of studies dealing with the structure of various facets of the Coleoptera system, such as morphology, embryology, physiology, ecology, etc., have been concisely summarised.

THE USE OF LEAD CITRATE AT HIGH pH AS AN ELECTRON-OPAQUE STAIN IN ELECTRON MICROSCOPY
TL;DR: The stain reported here differs from previous alkaline lead stains in that the chelating agent, citrate, is in sufficient excess to sequester all lead present, and is less likely to contaminate sections.

Histochemistry, theoretical and applied
TL;DR: The new Pearse bids fair to become the leader, even amongst so notable a collection of books devoted entirely or largely to histochemical techniques.

Synthesis of the carbohydrate of mucus in the golgi complex as shown by electron microscope radioautography of goblet cells from rats injected with glucose-h3
Marian R. Neutra,C. P. Leblond +1 more
TL;DR: The evidence indicates that the Golgi saccule is the site where complex carbohydrate is synthesized and is added to immigrant protein to form the complete glycoprotein of mucus.

Radioautographic comparison of the uptake of galactose-h3 and glucose-h3 in the golgi region of various cells secreting glycoproteins or mucopolysaccharides
Marian R. Neutra,C. P. Leblond +1 more
TL;DR: Radioautography after injection of galactose-H3, as after glucose- H3, indicates that synthesis of complex carbohydrates takes place in the Golgi region of many secretory cells.
