Pollen traps, in conjuction with walnut leaf smoke or mint leaves, were tested as a control For tor. Experimental colonies were left untreated for one year prior to use in this study. Four treatment groups were tested: I - walnut smoke+pollen trap, II - paper smoke+pollen trap, III - walnut smoke only, and IV - mint leaves+pollen trap. Group V remained with no treatment. Both treatment and time were significant factors in the reduction of mites, as was the interaction effect (treatment x time). Although all treatments with pollen traps reduced mite population by approximately 50%, the treatment without pollen trap reduced mite population significantly more.
