degradation products in honey and beeswax.

A study on the possible degradation of amitraz, bromopropylate, coumaphos,
chlordimeform, cymiazole, flumethrin, and tau-fluvalinate during the
storage of honey was carried out by HPLC. Except amitraz, the other
acaricides are stable in this medium for at least 9 months. Degradation
studies of amitraz in honey and beeswax were carried out; the degradation
products detected in both matrices were 2,4-dimethylphenylformamide (DMF)
and N-(2,4-dimethylphenyl)-N'-methylformamidine (DPMF). The reaction rate
constants and the half-lives of the amitraz degradation in honey and wax
were calculated. Amitraz was nearly completely degraded within 1 day in
beeswax and within 10 days in honey. When amitraz-spiked combs are recycled
into new beeswax, DMF was found to be the principal degradation product
left in pure wax.

Additional notes:

There is very little information on the solubility of the metabolites, at
least one of them apparently being water soluble to some extent, since it
is tested for in race horse urine.  It appears that we really don't know
the metabolic fate, distribution, or effects of the amitraz metabolites in
the hive that well.
