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.
采用高效液相色谱法对蜂蜜储存过程中双甲脒、溴螨酯、蝇毒磷、杀虫脒、咪唑菌酮、氟氯氰菊酯和氟胺氰菊酯可能的降解情况进行了研究。除双甲脒外，其他杀螨剂在该介质中至少9个月内是稳定的。开展了双甲脒在蜂蜜和蜂蜡中的降解研究；在两种基质中检测到的降解产物均为2,4-二甲基苯甲酰胺（DMF）和N-（2,4-二甲基苯基）-N'-甲基甲脒（DPMF）。计算了双甲脒在蜂蜜和蜂蜡中的反应速率常数及半衰期。双甲脒在蜂蜡中1天内几乎完全降解，在蜂蜜中10天内几乎完全降解。当将添加双甲脒的巢脾回用于新蜂蜡时，发现DMF是纯蜂蜡中残留的主要降解产物。
