摘要

蜂蟹蟎（Varroa jacobsoni Oudemans）為蜜蜂身上的外寄生蟎，牠是西洋蜂（Apis mellifera L.）最嚴重的敵害，被寄生蜂群的蜂勢變弱，嚴重者會整群滅亡。本文利用室內試驗，評估福化利、蟎扑立克與三亞蟎等三種殺蟎劑的藥效，結果顯示，福化利的殺蟎率與殘效性最佳，浸泡福化利的藥片置於蜂群15日後的殺蟎率仍達83%以上，放置30日後的殺蟎率亦達51%以上。田間試驗則選擇浸泡5%福化利的藥片進行防治試驗，結果顯示，群勢較強蜂群的蜂蟹蟎防治率可達94.7－100%，群勢中等的蜂群防治率則為54.8－80.8%，如此說明福化利可做為防治蜂蟹蟎的主要藥劑，三亞蟎則可做為替代藥劑之用。

Varroa jacobsoni Oudemans is an ectoparasitic mite of the honey bee, Apis mellifera L., that is having a serious impact on managed honey bee populations around the world. Infestations of this mite may cause a large reduction and or the extinction of bee colonies. A laboratory bioassay was developed to evaluate the control effects of three miticides; i.e. fluvalinate, Marvirik, and amitraz. Results showed the fluvalinate presented the best control effects. Wood strips containing fluvalinate caused upper than 83% of mite mortality onday 15 after introducing inside the hive, and more than 51% of mortality on day 30. In field studies, 5% of fluvalinate strips were selected to investigate the control effects in bee colonies. ResuIt showed the strong bee colonies received a 94.7-100% of control rate, and moderate colonies received a 54.8-80.8% of control rate. These results indicate that fluvalinate may possess a major control reagent and amitraz may be an alternative reagent on Varroa mite control.
