I read something about a plastic sheet with copper wire on top af it. 3 inch deep and wide as the entrance On the copperwire there are electric shocks (not 10.000 volt please) probaly on and on plus and minus. One bee must contact both wire and the sheet, so the tunnel is 1/4 inch high. Bees are guided for the entrance to go through the tunnel The bees will sting in the plastic sheet, and on the undersite ther will be some verom drip. -------------------------------------------------------- Jan Tempelman / Ineke Drabbe | EMAIL:[log in to unmask] Sterremos 16 3069 AS Rotterdam, The Netherlands Tel/Fax (SOMETIMES) XX 31 (0)10-4569412 homepage webside: http://www.xs4all.nl/~jtemp/index2.html webside van het AmbrosiusGilde: http://www.xs4all.nl/~jtemp/ambro_index.html webside for NECTAR: http://www.xs4all.nl/~jtemp/nectar_index.html with some pages in english on solitary bees.
