Dear Bee liners, I am in the process of designing a new bee flight room (bfr) at Rothamsted, which we hope to use to rekindle our work on pheromones and semiochemicals. I am interested in info on bfr's from anyone with experience of them, and preferably with an up to date WORKING version. I am familiar with Van Praagh'sa system, but I want to try and develop a more modern version of his classic design. If anyone can help me directly, or knows of someone who can, please contact me Guy Poppy Dept Entomology/Nematology Rothamsted Experimental station Harpenden, Herts UK AL5 2 JQ
