Twenty-four honeybee (Apis mellifera) colonies were used to monitor the efficacy of a solution of 2.9% oxalic acid (OA) and 31.9% sugar against the mite Varroa destructor. Mite mortality was established prior to and after OA treatments, which were conducted in August and September. The treatments resulted in 37% mite mortality as opposed to 1.11% in the controls. OA treatment conducted in September on previously untreated colonies resulted in 25% mite mortality. OA treatments in October and November resulted in approximately 97% mite mortality. These results suggest that OA is effective during the broodless period and less effective when applied to colonies with capped broods. The possible use of OA against the Varroa mite in honeybee colonies as an alternative to routine chemical treatments is discussed.
使用24个蜜蜂（意大利蜜蜂）蜂群来监测2.9%草酸（OA）和31.9%糖的溶液对狄斯瓦螨的防治效果。在8月和9月进行OA处理前后测定了螨虫死亡率。处理导致37%的螨虫死亡，而对照组为1.11%。9月对先前未处理的蜂群进行OA处理导致25%的螨虫死亡。10月和11月进行OA处理导致约97%的螨虫死亡。这些结果表明，OA在无幼虫期有效，而应用于有封盖子脾的蜂群时效果较差。讨论了OA作为常规化学处理的替代方法在蜜蜂蜂群中防治狄斯瓦螨的可能用途。
