Abstract - We show that the stingless bees Melipona panamica and Partamona peckolti have a high precision of intra-patch recruitment that is influenced by forager-deposited odor marks in the field. We trained foragers to a 2.5 M sucrose feeder in the center of an array of five identical feeders (20 cm between feeders) at different distances and directions from the nest and measured the distribution of recruit visitations. In the free-foraging phase foragers could odor mark a filter paper around the experimental feeder, and in the odor-removal phase we substituted it each five minutes by a clean one. Significantly more recruits in both species chose the experimental feeder over the controls in the distance and directional arrays (P $\leq$ 0.034) and odor removal significantly decreased precision of recruitment in both species (P $\leq$ 0.034). Scent marks in both species thus play a significant role in orienting recruits to already known profitable food sources.

Key words: odor marking / recruitment / stingless bees / intra-patch precision / Meliponini

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.
