Last week there was a conversation regarding bait traps and pheremone
lures.  I just received a catalog from Great Lakes IPM that includes
two different styles of bait traps (box and cone) and lures for European
and Africanized Bees.  Additionally, they have a product called
BEE-SCENT for pollination purposes.  These are made by a company called
Scentry which used to advertise in some of the North American bee
journals.  Besides apis mellifera, they have hundreds of other types of
baits, lures, traps.  If anyone is interested, their number is (517)
268-5693 or (517) 268-5911 for Great Lakes IPM.
