“…In bees, the presence of glands in legs was first reported by ARNHART (1923) and CHAUVIN (1962) in the last tarsomere of both sexes and castes of Apis mellifera Litmaeus, 1758. This tarsal gland is constituted up of a epidermal fold inside the tarsus forming an epithel ial sac where the secretion is apparently stored .…”

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.

“…Crawling worker honeybees also lay odour trails, which, unlike those of ants, are more or less continuous from their inception; the so far unidentified pheromone ('epagine c ' of Chauvin, 1962) is deposited by the feet and possibly also the tip of the abdomen (Butler, 1966). A trail is laid, for example, when a hive is turned so that a side wall faces in the direction previously faced by the entrance.…”

“…Although their chemistry is unknown, the biology of a few has been explored. One that is left on dishes and other objects crawled over by honeybees ('epagine e', Chauvin, 1962) occurs on most parts of a worker's body, particularly her feet, where it may be produced in Arnhardt's glands (Butler, 1966;Chauvin, 1962). It is very attractive to foraging honeybees, possibly even more so than the Nassanoff gland scent of the worker, and persists for 10 min.…”

“…A distinction can be made between modifying pheromones (primers), which provoke a physiological change in the insect (e.g., inhibition of ovarian development in workers of the honey bee Apis rnellifera L.) and, consequently, a change in their behaviour, and releasing pheromones (releasers), which trigger instantaneous and reversible behavioural responses in the insect (e.g., aggregation, alarm, and sex 1986), and Apis rnellifera L . (Apidae) (Arnhart 1923;Chauvin 1962;Lensky et al 1984Lensky et al , 1985.…”

POUVREAU, A. 1991. Morphology and histology of tarsal glands in bumble bees of the genera Bombus, Pyrobombus, and Megabombus. Can. J . Zool. 69: 866-872. The last tarsal segment and pretarsus of adult bumble bees are described. The tarsal gland on the fifth tarsomere of each leg in all individuals of a colony consists of simple glandular epithelium surrounding a reservoir in which its secretory products accumulate. Movement of the pretarsus in and out of the fifth tarsomere helps to discharge the secretion of the gland onto the ventral surface of the arolium. Study of the fine structure of the glandular cells reveals the presence of cytoplasmic organelles involved in secretion. The apical surface of the cells bears numerous microvilli associated with a smooth endoplasmic reticulum. Ergastoplasm is mainly located in the basal region. The spherical or ovoid nucleus is generally located basally and the cytoplasm contains uniformly distributed Golgi complexes, ribosomes which vary in number from one area to another, more or less electron-dense multivesicular bodies, mitochondria, and pinocytotic vesicles and coated vesicles in the cytoplasm of the apical area. Interdigitations and desmosomes contribute to the cohesion of cells within the epithelium. The tarsal gland of bumble bees is compared with that of other insects, and the function of its secretion is considered.POUVREAU, A. 1991. Morphology and histology of tarsal glands in bumble bees of the genera Bombus, Pyrobombus, and Megabombus. Can. J . Zool. 69 : 866-872. L'auteur donne une description de la morphologie du dernier article du tarse et du prCtarse chez les Bourdons. Une Ctude morphologique de la glande tarsale, prCsente dans le cinquieme tarsomere des trois paires de pattes chez tous les individus de la colonie, met en evidence un CpithClium glandulaire, constituC d'une seule couche de cellules, qui entoure un reservoir dans lequel s'accumulent les produits de sCcrCtion. Les mouvements du prCtarse par rapport au tarse permettent d'expliquer comment s'effectue 1'Ccoulement de la sCcrCtion de la glande tarsale a la surface ventrale de I'arolium. L'Ctude ultrastructurale rCvele la pr6sence d'organites cytoplasmiques en relation avec une activitC sCcdtrice. La surface apicale des cellules CpithCliales comporte de nombreuses microvillositCs au voisinage desquelles se trouve un rkticulum endoplasmique lisse, tandis qu'un ergastoplasme est localis6 principalement dans la rCgion basale. Le noyau, sphkrique ou ovo'ide, tend a occuper une position entre le centre de la cellule et le tiers de la basale. Le cytoplasme contient des appareils de Golgi, a repartition uniforme, des ribosomes, dont le nombre varie d'une rCgion a l'autre de la cellule, des corps multivCsiculaires, des mitochondries, des vCsicules de pinocytose et des vCsicules de type << vCsicule r e v h e ,,, ces derniers organites Ctant prCsents notarnment dans la rCgion apicale. Un systeme d'interdigitations et de desmosomes contribuent a la cohCsion des cellules c8te a c8te. La discussion porte sur la ...
