No residue higher than 0.01 mg.kg-1 was detected in honey. Even in other
studies, in which amitraz as administered by aerosol, very low or no
residues were found (Avila et al., 1990; Lodesani et al., 1992; Fernandez et
al., 1997). For instance, in East Germany, out of 330 honey samples analysed
in 1986-1990, only 8.5% them contained more than 0.05 mg of amitraz.kg-1
(Hemmerling et al., 1991). The low residue values, generally determined in
honey even when
amitraz is directly administered in the hive, are probably due to its fast
degradation (2-4 weeks) (Jiménez et al., 1997).
