 Title    Vergleichende Untersuchungen zur Wehrchemie und Drüsenmorphologie abdominaler Abwehrdrüsen von Kurzflüglern aus dem Subtribus Philonthina (Coleoptera, Staphylinidae) Comparative Investigations on Defensive Chem istry and G land Morphology of Abdominal Defensive G lands from Rove Beetles of the Subtribe Philonthina (Coleoptera, Staphylinidae)  
 Abstract    Within the rove beetle subtribe Philonthina (Staphylinidae) there are found paired abdom inal defensive glands which show a bipartition and are characterized by an unique, evaginable evapo­ ration tissue which is described for the first time. The gland chemistry is found to be character­ ized by at least 27 compounds. The m ain com ponent is represented by the alkaloid actinidine, m i­ nor components are iridodial, three possible m onoterpenoid iridodial precursors, an octadecenole and two series o f hydrocarbons and acetates which are partly branched and unsaturated. It could be shown, that the separated gland o f the evaporation tissue, whose evagination was studied, has no different synthetic abilities as com pared with the main gland system. Chemotaxonomic results according to Hennig's principle reveal an isolated position of the rove beetle tribe Q uediini within the subfamilies X antholininae and Staphylininae. The morphologically unique defensive gland of the X antholininae may be homologized with other abdom inal glands o f the Staphylinina and Philonthina, based on the comm on presence of iridoid defensive components.

 Title    The Exocrinology of the Queen Bumble Bee Bombus terrestris (Hymenoptera: Apidae, Bombini)  
 Abstract    Chemical analyses are presented of prominent exocrine glands of queen B om bus terrestris including mandibular, labial and hypopharyngeal glands in the head, Dufour's gland and tarsal glands. A plethora o f about 500 substances were identified belonging to various ali­ phatic compounds including hydrocarbons, various classes of esters, alcohols, methyl ketones and fatty acids. A group of chiral hydroxy acids and their butanoic acid esters are reported for the first time in bees.
