Subject: [FloridaBeekeepers] Re: Digest Number 82

at the eas meeting last week, j.baxter of usda/weslaco(tx) beelab
announced that tolerance levels would be set at 100ppb in honey and
100ppm in wax, more than double the levels found under worst-case
scenarios in studies...restrictions on use in comb-honey production
to be lifted but the 2-week post-treatment lag remains in place...
however, (if) these residues are cumulative, especially in broodcomb/
beeswax, dose/frequency of treatment could affect development of
coumaphos-resistant mites (already reported in europe?)...another
study to be presented at the abrc was to report preliminary results
showing use of coumaphos in queen-rearing operations resulted in
smaller/lighter queens...yet another presentatin on the use of
household products to control beetle larva indicated that bleach and
detergent solutions sprayed on comb were effective (no field test or
residue check but bees in lab were working comb 24-48hrs. later),
whereas water (control)and vinegar solution actually stimulated
larval activity!
