Regarding the request for information: I just noticed an article in the Alberta Bee News, May 1993. It is Extra income from bee venom collecting, by M. Simics and C. Fogarassy. There is a reference list with 11 entries, including Galuska, H 1972 Collection of bee venom by means of electric current Zoologica Polloniae Vol 22 p53-69. and Charles Mraz, 1982 bee venom for arthritis. ABJ p 121-123 There is likely something more recent. (i've heard of a grid of fine wires with an electrical potential diff on alternate wires. the grid with an underlying tray is inserted into a hive entrance, and the bees try to sting between the wires, depositing venom on the tray. good luck
