Abstract
In this study the efficiency of bee traps used to evaluate mortality in a bee colony and their influence on undertaking behaviour was tested in twelve colonies of Apis mellifera L. Four types of bee traps (Original-Gary-Trap, a Modified-Gary-Trap, the IPSAB-Trap and the Muenster-Trap), commonly used in practical research, were compared to each other and to control colonies without a trap. The use of different bee traps led to incomparable results. In the Original-Gary-Trap, many stray bees were trapped and eventually died within the glass collecting jars, leading to artificially high estimates of mortality. Bees removed the dead bees from the Modified-Gary-Trap, especially during good flight conditions. Dead bees disappeared from the IPSAB-Trap because of predators and wind. Both Gary-Traps had a negative effect on undertaking behaviour; the number of behavioural components involved in removing a dead bee from the colony was large and thus, undertaking took a long time. In IPSAB-Trap, the undertaker bees showed the same number of behavioural components and took similar times to remove dead bees as the control colonies without traps. The newly developed Muenster-Trap, equipped with an easily accessible hive entrance, a collecting box for dead bees and an outlet for stray bees, gave a significantly improved performance.


Key words: Apis mellifera / undertaking behaviour / bee traps / mortality evaluation

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.
