“…Svensson and Bergström (1977) found that diterpenic components in the labial gland secretion of B. pratorum males appear later in the season. Ågren et al (1979) studied changes in the labial gland secretion of B. hypnorum males since 5 days before eclosion until day 7 after emergence.…”

“…Currently, the composition of male cephalic gland secretion is used as the most efficient tool for taxonomic identification, species and subspecies discrimination (Paterson, 1985;Terzo et al, 2005;Rasmont et al, 2005;Coppée et al, 2008). However, a great individual variability in the production of pheromonal components was observed within a single species (Svensson and Bergström, 1977;Ågren et al, 1979;Šobotník et al, 2008), which makes taxonomic application sometimes a difficult task, especially in related species. Recently, changes of the cephalic labial gland ultrastructure related to age of males were reported in B. terrestris (Šobotník et al, 2008).…”

“…Scarce reports on seasonal variations in the secretion composition in some other species appeared in the literature (Kullenberg et al, 1970;Svensson and Bergström, 1977;Ågren et al, 1979) but this phenomenon has not been studied systematically so far.…”

-Quantity of components of the labial gland secretion of bumblebee males changes significantly during ageing of males. In B. terrestris, compounds showing the EAG-activity to virgin queens are ethyl dodecanoate, 2,3-dihydrofarnesal, 2,3-dihydrofarnesol, hexadecanol, octadeca-9,12,15-trienol, and geranylcitronellol. The EAG-active compounds found in B.lucorum are ethyl dodecanoate, ethyl tetradec-7-enoate, ethyl tetradec-9-enoate, ethyl hexadec-9-enoate, hexadecanol, hexadec-7-enal, octadeca-9,12-dienol, octadeca-9,12,15-trienol and octadecanol. Quantification of these compounds based on a calibration showed that the main components were present in milligram amounts in both species. Different concentration pattern of active compounds was observed in the species studied. Compounds reached maximal amounts about seventh day after eclosion. Then, a rapid concentration decrease occurs in B. terrestris whereas the amounts of active compounds stay approximately constant or decreases only slowly in B. lucorum. These results were also confirmed by means of optical microscopy. B. terrestris secretory cells undergo apoptosis since the fifth to the tenth day of life, whilst they live and show secretory activity through the whole life of B. lucorum males.

Les auteurs comparent les descriptions des phéromones sexuelles des mâles de bourdons publiées avant et depuis 1996. Ils mettent en évidence une importante différence dans la quantité de molécules décrites entre ces études. Cette différence s’explique notamment par l’importante évolution dans l’informatisation des données et de leur analyse. Elle s’explique également par les objectifs des premières études, limitées alors à décrire et à démontrer la spécificité de ces phéromones. Les études menées depuis 1996 montrent que la majorité des molécules sécrétées sont présentes sous forme de traces. Néanmoins, ces molécules sont d’importance majeure pour toute étude entrant dans le concept moderne d’analyse phylogénétique globale («total evidence approach»). La redescription complète de ces phéromones pour les espèces étudiées avant 1996 apparaît donc indispensable.The authors compare the descriptions of the sexual pheromones of male bumblebees published before and since 1996. They reveal the strong difference in described molecule quantities between those studies. Such differences can be mainly explained by the progress of the computed data acquisition and analysis. They can be also explained by the aims of those first studies, limited at that time to the description of pheromones and to convince of their specificity. The studies carried out since 1996 show that the main proportion of secreted molecules are only present as traces. Those molecules are nevertheless of major interest for phylogenetic studies dealing with the modern concept of total evidence approach. The complete redescription of the pheromones of species treated before 1996 is thus essential

“…Bombus (Pyrobombus) lapponicus (Fabricius) s.s. has been separated from B. monticola Smith because of the differences in their marking secretions (Bergström and Svensson, 1973a;Svensson and Bergström, 1977;Svensson, 1979aSvensson, , 1980. In the same way, it has been determined that Bombus (Bombus) lucorum (L.) includes other taxa, identified by most authors as B. cryptarum (Fabricius) and B. magnus Vogt (Bergström et al, 1973;Rasmont, 1981Rasmont, , 1983Rasmont et al, 1986;Bertsch, 1997a, b;Pamilo et al, 1997;Urbanova et al, 2001;Valterová et al, 2002;Terzo et al, 2003).…”

Cephalic secretions of the bumblebee subgenus Sibiricobombus Vogt suggest Bombus niveatus Kriechbaumer and Bombus vorticosus Gerstaecker are conspecific (Hymenoptera, Apidae, Bombus)

-Three taxa of the subgenus Sibiricobombus live in the Near-East mountain steppes: Bombus niveatus, B. sulfureus and B. vorticosus. The latter is also present in the Balkan. B. niveatus and B. vorticosus can only be distinguished based on color pattern. B. sulfureus differs in coat color and in genitalia. We identified 40 compounds in the secretions of the labial glands of these taxa, among which 7 were detected for the first time in labial cephalic gland secretions of bumblebee males. Whereas the secretions of the male cephalic labial glands of B. sulfureus are very different from those of B. niveatus and B. vorticosus, we found no significant difference between the latter. We conclude that B. sulfureus is a valid species, whereas B. vorticosus is a mere subspecies of B. niveatus: Bombus niveatus ssp. vorticosus Gerstaecker nov. status. cephalic secretions / Sibiricobombus / Bombus / taxonomic status / chemical composition
