Abstract In the primitively eusocial sweat bee, Lasioglossum malachurum, 66 volatile compounds could be identified from queen Dufour’s gland secretions. The patterns found in gynes and in old nesting queens differed in the absolute amounts of extractable volatiles as well as in the relative proportions. 3-Methyl-3-butenyl octadecanoate is the main component in gynes, while 18-octadecanolide, 20-eicosanolide and 22-docosanolide largely dominate the bouquets of old queens. The probable roles of some specific compounds in pheromonal communication of mates and in nest recognition are discussed. Correlations with the volume of the fat body and the vitellogenic status of the ovary are described.

Match Factor

Diurnal activities ofHalictus scabiosaebees and their nest parasites (major bee-flies, cuckoo wasps, ichneumon wasps,Sphecodesbees, and velvet ants) were investigated at a study site with 159 nests in Eastern Austria. Foraging activity correlated with ambient temperature only before midday and decreased in the afternoon. The activity of nest-infesting parasites increased during the day and correlated with ambient temperature. The match factorfmbetween the ratios of the foraging activities ofH. scabiosaeand the ratios of aspects of morning temperature was assessed on three consecutive days with different weather. The activity patterns of halictine bees and their nest parasites differed: the parasites exhibited only small time windows in which their activities were synchronised with those of their hosts. The bees exhibited an anticyclic behaviour and collected food in times of low parasite pressure and decreased foraging activity when parasite pressure increased.
