“…Contrarily to what was observed in other heteropteran species, i.e. Rodnius prolixus (Stål) (Huebner 1980) and Lygaeus simulans (Deckert) (Gschwentner & Tadler 2000), where the glandular epithelium is formed by class 1 secretory cells (Noirot & Quennedey 1974, Quennedey 1998, the secretory units in M. histrionica belong to class 3. Each secretory unit is composed of a secretory cell and a duct cell responsible for the production of the cuticular evacuating duct (Fig 6).…”

The spermatheca of Murgantia histrionica (Hahn) was investigated using luorescence, scanning and transmission electron microscopy. The aim of the study was to elucidate the structure of this organ, pointing out differences between mated and unmated females. Results have shown an elaborated cuticular structure associated with muscular and glandular tissues. The spermatheca is joined with the common oviduct by the spermathecal duct, forming a thin saccular dilation through two consecutive invaginations. The distal part of the organ is formed by a series of two communicating cuticular chambers. The irst cylindrical-shaped chamber, corresponding to the coiled region, is wrapped by longitudinal muscular ibers suspended between two cuticular langes. The contractions of these ibers compress a deformable zone of the cylinder, pumping the sperm toward the spermathecal duct. Without contractions the cylinder results to be isolated from the proximal part of the spermatheca by means of a valve. The second chamber, corresponding to the spermatheca, is made of two parts: a truncated-conical sub chamber, with a constant cuticular thickness, bearing on itself the distal lange, where muscular ibers are attached. The second part is a bulb-like structure wrapped in a glandular epithelium. The secretory units are composed by two cells: a secretory cell and an associated duct cell. Every evacuating duct shows a little reservoir just after the terminal apparatus, and converge inside the distal bulb after a tortuous path. The functional implications of this structure in the reproductive biology of M. histrionica are discussed.

“…Since NOIROT & QUENNEDEY (1974) classified the tegumentar gland cells of insects in three different classes, in this report the epithelial glands that form a sac was numbered as IV. This is the case of femural glands present in queens and the tarsal gland present in the distal tarsomere.…”

Note on glands present in meliponinae (Hymenoptera, Apidae) bees legs

et al. 1998

ABSTRACT. The present paper reports the presence of glandular stlUctures in legs of some stingless bee species. The glands appear as: the epidermis transformation in a glandular epithelium as in basi tarsus, an epithelial sac inside the segment as in the femur of queens or in the last tarsomere, as round glandular cells, scattered or forming groupments. The saculifollll gland offemur is present only in queens, the other glands are present in males, queens and workers of the studied species, apparently without any type of polymorphism. This occurrence seems indicate that the function of these glands have not to do with the soc iality or spec ific behavior of castes.

Although 13 exocrine glands have been located in wasps of the genus Polistes, and 12 in Mischocyttarus (Landolt and Akre, 1979), their morphology and functions have been little studied. Recently, however, the sternal gland on the sixth gastral (terminal) segment of females of these wasps has attracted attention because its secretion is repugnant to some species of ants. Female wasps rub the secretion onto the nest petiole, thus forming a chemical barrier against predatory ants (Jeanne, 1970; Hermann and Dirks, 1974; Turillazzi and Ugolini, 1978, 1979; Post, 1980).Close to the anterior margin ofthe sternite is a hyaline area covered with a tuft of long hairs (‘sternal brush’) (van der Vecht, 1968). In Polistes a cluster of gland cells underlies the cuticle on each side of the sternal brush (Landolt and Akre, 1979; Turillazzi, 1979). Ducts lead from the gland cells to the cuticular surface within the sternal brush. A smaller number of gland cells also occurs in a band along the anterior margin of the fifth gastral sternite (Hermann and Dirks, 1974; Turillazzi, 1979).We undertook the present study to determine the presence of these glands in Polistes fuscatus (F.), a temperate zone species, and in P. canadensis (L.), a tropical species, and to compare the size and morphology of the glands in these species with those in congeners previously investigated by Hermann and Dirks (1974) and Turillazzi (1979)
