 Title    Spurorientierung bei W aldameisen  
 Abstract    (F orm ica p o ly c te n a Förster) Trail Orientation of Wood Ants (.Formica polyctena Förster) Workers of Formica polyctena Förster (Hymenoptera, Formicidae) follow artificial trails made with the contents of mandibular glands, poison glands, Dufour glands and rectal glands of their own species, as well as recruitment trails of Lasius fuliginosus (Latreille) or Myrmica ruginodis Nylander. Some specialized out-door workers prefer poison trails, as do workers irritated by a marking procedure. After withdrawal of sugared water the workers prefer rectal trails. Workers of hungry colonies also follow trails made with sugared water or faeces of tortricid larvae.

 Title    Multicomponent Mandibular Gland Secretions in Three Species of Andrena Bees (Hym., Apoidea)  
 Abstract    50 volatile constituents o f the mandibular gland secretions in males and females o f three species o f Andrena bees, A. wilkella (Chr.), A. ovatula (K .) and A. ocreata (K .), have been identified. The secretions are made up o f a series o f spiroacetals o f four different systems together with m ono-terpenes and unbranched acyclic compounds. Many o f the com ponents, particularly several o f the dominant ones, occur in both sexes o f all three species, so that the volatile secretions are qualita­ tively very similar. Females contain about 100 |ig per individuum , which is 3 -5 tim es the amount o f the males' secretions. Major spiroacetals are E,E-and Z ,E -2 ,8-dim ethyl-1,7-dioxa-spiro[5.5]undecane and E,E-and Z ,£-2-ethyl-7-m ethyl-l,6-dioxaspiro[4.5]undecane, while prom i­ nent monoterpenes are geraniol and citronellol. Straight chain hydrocarbons C 17, C19, C 21 and C23 occur in fairly large amounts, mostly with increasing concentrations. W ith respect to the quantita­ tive distribution o f components o f minor concentration, the bouquet o f A. wilkella is clearly dis­ tinguishable from A. ovatula and A. ocreata which from the m orphological and ethological point o f view are more closely related. Behaviour tests with A. w ilkella indicate high biological activity o f the main spiroacetal.

 Title    Coupled Gas Chromatography — Single Cell Recording: a New Technique for Use in the Analysis of Insect Pheromones  
 Abstract    A method is described for the continuous biological monitoring of the effluent from a high resolution gas chromatographic column using a single cell recording technique. The system can be used to provide precise information on the retention times of compounds with olfactory activity that are not detected with a coupled gas chromatograph -electroantennogram system.
