Toxicity of acaricides such as amitraz, bromopropylate, coumaphos, dicofol and phosalone on the European Honey Bee (Apis mellifera L.) were determined by the topical and feeding application. The result indicated that most of acaricides gave highest toxicity to the honey bee. Dicofol (Kelthane), and bromopropylate were found to be moderately toxic to the honey bee whereas coumaphos (Azuntol), Phosalone (Zolone), coumaphos (Perizin), dicofol (Rotramite) and amitraz (Mitac) were highest toxic. The result also showed the acaricides with different formulations showed different toxicity to the honey bee.
