Abstract - Polyandry in queen honey bees (Apis mellifera) prolongs the duration of nuptial flights which increases costs and risks. Under conditions of limited drone numbers the hypothesis was tested whether or not there is a threshold for successful mating during mating flight. In 29 queens we found a significant negative correlation between mating flight duration and number of spermatozoa in the spermatheca (Pearson r = -0.38, P = 0.04). This negative correlation supports the idea that queens continuously get information on her mating success during flight and return to the colony as soon as they have met a sufficient number of drones. In case of normal availability of drones queens fly from 10 to 30 minutes, so we compared 2 groups of queens (flight duration less than 30 versus more than 30 minutes). Sperm numbers differed significantly between the two groups (3.0 $\pm$ 0.77 and 1.1 $\pm$ 1.04 million, Wilcoxon, P < 0.001). These results further indicate that queens monitor mating success during flight.

Key words: mating success / nuptial flights / flight duration / sperm numbers / behavioral response

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.
