Abstract

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.

꿀벌(Apis mellifera)의 중요 해충인 꿀벌응애(Varroa destructor)에 대한 한국화학연구원과 동부하이텍이 공동으로 개발한 신규화합물 K16776(6.6 EC)과 꿀벌응애 방제약으로 사용되고 있는 amitraz(20 EC), 점박이응애 방제약으로 등록된 5종의 약제, 그리고 꿀벌응애 방제약으로 사용되고 있는 중국약제 2종에 대한 살비활성($15{\times}7.5{\times}7.5\;cm$)을 소형용기와 야외 벌통에서 수행하였다. 소형용기에 K16776과 amitraz는 100%의 살비활성을 나타내었으며, 꿀벌에 대해서는 독성이 없었다. 그 외 acequinocyl, bifenazate, chlorfenapyr, fenpyroximate, milbemectin은 활성을 보이지 않았다. 야외 벌통에서 실험한 결과, K16776은 250배와 500배에서 각각 98.7%와 88.6%의 높은 살비활성을 보였으며, 꿀벌에 대해서도 영향을 미치지 않았다. Amitraz도 500배와 1,000배에서는 각각 100%와 90%의 살비활성을 나타내었다. 중국약제인 초살산만편과 왕스는 각각 56.9%와 66.7%의 살비활성을 나타내었다. 이상의 결과에서 신규화합물인 K16776는 꿀벌응애 방제약으로 개발이 가능할 것으로 생각된다.
