Abstract - In honeybees, the rate at which a nectar forager unloads its crop to a receiver is positively correlated with the reward conditions the forager has recently experienced outside the hive. Food-receiver bees often share the nectar they have received with hive mates. A quantitative analysis of two consecutive trophallactic events was done in experimental arenas to determine if the food-transfer behavior of a food-receiver as she distributes nectar to her hive mates is affected by her prior trophallactic experience with a donor forager. We found that the rate at which a receiver unloads nectar to another receiver is positively correlated with the rate at which she received it from a food donor, suggesting that it is possible to propagate, through individual-to-individual interactions, information about quantitative aspects of the liquid food circulating among worker honeybees.


Key words: Apis mellifera / trophallaxis / unloading rate / communication

What is OpenURL?

The OpenURL standard is a protocol for transmission of metadata describing the resource that you wish to access. An OpenURL link contains article metadata and directs it to the OpenURL server of your choice. The OpenURL server can provide access to the resource and also offer complementary services (specific search engine, export of references...). The OpenURL link can be generated by different means.
  • If your librarian has set up your subscription with an OpenURL resolver, OpenURL links appear automatically on the abstract pages.
  • You can define your own OpenURL resolver with your EDPS Account. In this case your choice will be given priority over that of your library.
  • You can use an add-on for your browser (Firefox or I.E.) to display OpenURL links on a page (see http://www.openly.com/openurlref/). You should disable this module if you wish to use the OpenURL server that you or your library have defined.
