| Abstract | Several social bee species of the family Apidae use scent marks on flowers left by previous visitors to improve foraging efficiency, but scent marking has not been demonstrated in other social bees. Experiments were conducted to confirm the ability of the eusocial sweat bee Halictus (Seladonia) aerarius (Hymenoptera: Halictidae) to use scent marks to detect flowers within 3 min of foraging by the same individuals or by conspecifics. Rejection responses were evident on two plant species, Erigeron annuus and Justicia procumbens. The proportion of hovering rejection responses to visited flowers differed among plant species. Repellent responses to visited flowers of J. procumbens decreased without replenishment of nectar. We suggest that the duration of scent marks used by H. aerarius is not adjusted to nectar replenishment and that this bee uses different rejection responses depending on the resources expected when revisiting flowers. This strategy may be considered a basal trait in the bee’s evolution.Die räumliche Verteilung der Blütenressourcen ist komplex und schwierig vorhersagbar. Um Blüten effizient zu besammeln, nutzen die Bienen mehrere auf Blütensignalen wie Pollen und Nektar beruhende Strategien, mit denen sie die Blütenressourcen abschätzen. Zusätzlich zu diesen Signalen können soziale Bienen der Familie Apidae geruchliche Anzeiger wie die von früheren Blütenbesuchern zurückgelassenen Duftmarken wahrnehmen, um hierdurch ihre Sammeleffizienz zu steigern (z.B. Giurfa et al., 1994; Stout und Goulson, 2001; Schmidt et al., 2005). Einige Solitärbienen nutzen ebenfalls Duftmarken (Frankie und Vinson, 1977; Gilbert et al., 2001; Gawleta et al., 2005). Während Duftmar-kierung bei sozialen Bienen der Apidae gut dokumentiert sind, sind diese bei den sozialen Halictidae nur wenig untersucht. Wir führten Untersuchungen über die Fähigkeit der sozialen Furchenbiene Halictus (Seladonia) aerarius durch, anhand von Duftmarken zuvor besuchte Blüten zu erkennen. Hierzu schnitten wir kürzlich besuchte Blüten zusammen mit dem Blütenstiel ab und boten sie innerhalb von 3 Minuten den gleichen Individuen oder Artgenossen an. Hierbei wurden Ablehnungsreaktionen bei zwei Pflanzenarten, dem einjährigen Feinstrahl Erigeron annuus und dem Acanthusgewächs Justicia procumbens festgestellt (Abb. 1). Die Ablehnungsrate für Blüten von J. procumbens war größer als die bei Blüten von E. annuus (Abb. 2). Die Dauer der Ablehnung nahm bei beiden Pflanzen nach 60 Minuten ab (Abb. 3). Dies ist der erste Hinweis auf die Nutzung von Duftmarkierungen bei den sozialen Halictidae zur Erkennung bereits genutzter Blüten. Obwohl der Nektar bei J. procumbens nicht wieder aufgefüllt wurde (Abb. 4), nahm der Repellenteffekt besuchter Blüten mit der Zeit ab. Die Dauer der Nutzung von Duftmarkierungen durch H. aerarius war daher nicht auf die Nektarergänzung abgestimmt, und die Furchenbienen schienen unterschiedliche Ablehnungsreaktionen in Abhängigkeit ihrer Ressourcenerwartung beim Wiederbesuch der Blüten zu haben. Wir nehmen daher an, dass H. aerarius ihr Ablehnungsverhalten modifiziert um hierdurch die Sammeleffizienz zu steigern. Da Duftmarkierung von Blütenressourcen sowohl bei Honigbienen als auch bei Hummeln vorkommt, weisen unsere Ergebnisse darauf hin, dass dies eine in der Evolution der Bienen ursprüngliche Strategie darstellt. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
