"The  additional elements which are essential for animals, but for which  no
estimates of their
contents in honeybees could be found include  chlorine, iodine, bromide,
fluorine, selenium,
chromium, cobalt,  arsenic, molybdenum, nickel,  silicon, tin and vanadium
(Underwood,  1997).
Determination of the concentration of these elements in the body  of
honeybees would provide the
information needed to make an estimate of  their requirement for bees."



Juanese - we've done this for many of the elements listed - but not as  
nutritional supplements, rather as toxic pollutants.  Many of these are  toxic 
to bees - one might argue that micro-amounts might be nutritionally  
beneficial - but certainly flouride, nickel, arsenic, selenium, bromide aren't  
elements that you want to 'guess' at - I've been involved in many studies and  
some law suits regarding body burdens of toxic elements, and bee losses.
