   Before you purchase any such product, you should read an article that
appeared in the April issue of the AMERICAN BEE JOURNAL ("An evaluation of
selected commercial bee attractants in the pollination of cucumbers and
watermelons").  One of their conclusions:  "Neither product significantly
increased bee activity on the subject vine crops when compared to an
untreated control nor did they increase the value of the subsequent
harvest." (in their abstract).
 
   Our experience so far has been that there is no such thing as a general
honey bee attractant chemical, which is good --- colonies can then switch
from one crop to another with relative efficiency.
