This study examined the acaricidal activity of a new compound, K16776 against honeybee mite, Varroa destructor which is ecto-parasite of Apis mellifera. Acaricidal activity was performed using six acaricides, two Chinese commercial acaricides and one newly synthesized K16776 against V. destructor in the small container and in the bee hive. K16776 and amitraz exhibited 100% acaricidal activity against V. destructor without insecticidal toxicity to A. mellifera in the small container. The other acaricide was not activity. Applied to the bee hives, K16776 showed acaricidal activity as 98.7% ($250{\times}$) and 88.6% ($500{\times}$) and amitraz showed as 100% ($500{\times}$) and 90% ($1,000{\times}$), respectively. Made in China, Cao Suan Sha Man Pian and Wangs showed acaricidal activity as 56.9% and 66.7%, respectively. The result indicates that K16776 can be potentially useful control agent against honeybee mite, V. destructor.
