I always favored Waller's (1980) modified OAC trap. The addition of a trash trap and a ventilated pollen tray also help. On searching, I found these links, although not to his original paper. At the Tucson BeeLab, we commonly caught many pounds each year, and Waller's tests on the wisdom of full-time trapping showed no damage to colonies.
