چکیده
Andrena, Mandibular Glands, Pheromone, Spiroacetals The complex volatile secretion from the mandibular glands of Andrena haemorrhoa (Hym., Apoidea) has been analysed by GC/MS. It is composed primarily of three groups of compounds: 1. Spiroacetals of five different systems: two l,6-dioxyspiro[4.4]nonanes, four l,6-dioxaspiro[4.5] decanes, two l,7-dioxaspiro[5.5]undecanes, one l,6-dioxaspiro[4.6]undecane and one 1,7-dioxaspiro[5.6]dodecane. 2. Straight chain fatty acid derivatives: methyl ketones, primary and secondary alcohols, acetates and hydrocarbons. 3. Isoprenoids: geraniol and geranyl acetate. Mass spectral fragmentation patterns have been studied for several synthesized spiroacetals.

Honey Bee (Apis mellifera) Queen Reproductive Potential Affects Queen Mandibular Gland Pheromone Composition and Worker Retinue Response
Reproductive division of labor is one of the defining traits of honey bees (Apis mellifera), with non-reproductive tasks being performed by workers while a single queen normally monopolizes reproduction. The decentralized organization of a honey bee colony is maintained in large part by a bouquet of queen-produced pheromones, the distribution of which is facilitated by contact among workers thr...
متن کاملHoneybee drones are attracted by groups of consexuals in a walking simulator.
During the mating season, honeybee males, the drones, gather in congregation areas 10-40 m above ground. When a receptive female, a queen, enters the congregation, drones are attracted to her by queen-produced pheromones and visual cues and attempt to mate with the queen in mid-air. It is still unclear how drones and queens find the congregations. Visual cues on the horizon are most probably us...
متن کاملMorphology and ultrastructure of the allomone and sex-pheromone producing mandibular gland of the parasitoid wasp Leptopilina heterotoma (Hymenoptera: Figitidae).
Chemical communication by the parasitoid wasp Leptopilina heterotoma is based largely on (-)-iridomyrmecin. The female wasps use (-)-iridomyrmecin as a defensive allomone, a chemical cue to avoid competition with con- and heterospecific females, and as a major component of their sex pheromone to attract males. Males of L. heterotoma produce (+)-isoiridomyrmecin, which is also used for chemical ...
متن کاملMandibular gland secretions of meliponine worker bees: further evidence for their role in interspecific and intraspecific defence and aggression and against their role in food source signalling.
Like ants and termites some species of stingless bees (Meliponini), which are very important pollinators in the tropics, use pheromone trails to communicate the location of a food source. We present data on the communicative role of mandibular gland secretions of Meliponini that resolve a recent controversy about their importance in the laying of such trails. Volatile constituents of the mandib...
متن کاملChemical Profiles of Two Pheromone Glands Are Differentially Regulated by Distinct Mating Factors in Honey Bee Queens (Apis mellifera L.)
Pheromones mediate social interactions among individuals in a wide variety of species, from yeast to mammals. In social insects such as honey bees, pheromone communication systems can be extraordinarily complex and serve to coordinate behaviors among many individuals. One of the primary mediators of social behavior and organization in honey bee colonies is queen pheromone, which is produced by ...
