Abstract - In Apis mellifera the estimated average number of drones visiting a drone congregation area (DCA) was 11 750 + 2 145. Drones of the species Apis cerana, A. koschevnikovi, A. dorsata and A. mellifera, which pursued a queen dummy moving in circular course, flew in a comet shaped formation. Median numbers of drones in a comet ranged from 9 drones (A. koschevnikovi) to 31 drones (A. mellifera). In none of the species we observed aggression between drones. Drone density behind the queen and distance to the queen seemed to be adjusted to avoid collisions between drones. The median flight speed ranged from 2.6 m/s (A. koschevnikovi) to 4.1 m/s (A. dorsata). The median duration of a drone's presence in the mating comet did not exceed 2 seconds. Drones of all species had the ability of high acceleration (10 to 20 m/s²). Either by overtaking or leaving/entering the comet drones seem to compete for more promising positions. Only drones flying in a limited space of not more than 2000 cm³ behind the queen were successful in grasping the dummy.

Key words: Apis reproduction / mating behavior / drone congregation area / drone competition / drone numbers

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.
