摘要

本研究探討甲酸防治蜂蟹蟎的效果，評估其防治利用可行性。甲酸施放位置以巢框上的防治效果較佳，施放於巢框下則效果明顯降低。防治劑量以6ml/day和8ml/day較果最佳，防治率可達80%以上，但二者防治率無顯著差異。甲酸對成蜂存活率影響不大，但6ml/day和8ml/day劑量對封蓋工蜂房面積有顯著影響，分別使面積減少15%和58.5%；此二個劑量也會顯著影響蜂群取食糖水和代用花粉量，惟6ml/day劑量的影響較輕微。田間應用甲酸防治蜂蟹蟎，以6ml/day的劑量較適當，但防治劑量應嚴格控制，避免用量過多或不足，造成蜂群負面影響或防治效果不彰。

The honeybee mite Varroa jacobsoni Oudeman is the most serious pest of the honeybee in Taiwan. This study evaluates the possibility of utilizing a formic acid board to control this mite. Placing the formic acid board on the top of the comb frames produced the most effective results. There were no significant differences in mite control between application of 6ml/day and 8ml/day of formic acid. Both dosages gave more than an 80% control rate of Varroa mites. There were no significant differences in the survival rates of adult bees among different dosage treatments of formic acid from 2ml/day to 8ml/day. But treatments of 6ml/day and 8ml/day decreased capped worker cells an average of 15% and 58.5%, respectively. These treatments also influenced the amount of feeding by the bees on sugar syrup and pollen cake, but the influence of the 6ml/day treatment was less than the 8ml/day treatment. Application of 6ml/day of formic acid to control Varroa jacobsoni in a colony is recommended, and at this dosage adverse effects can be neglected.
