The decline in the bee colony strength due to high levels of infestations necessitates the development of new control methods. This study evaluates the effectiveness of glycerin-oxalic acid strips and essential oils in managing . The experiment was conducted in 2022 at the experimental apiary in Debelec, part of the Institute of Animal Husbandry in Kostinbrod. Six experimental groups, each treated with a different preparation, were compared to a control group of untreated colonies. Treatments included Beevital Hiveclean (20 ml per colony), Varro Red (2 ml per frame), ammonium nitrate strips (1.3 mm), glycerin-oxalic acid strips (1.3 mm), and glycerin-oxalic acid strips of paper-cellulose (2.3 mm) or cellulose-cotton (2.3 mm). The control group remained untreated. The glycerin-oxalic acid strips made of cellulose and cotton (2.3 mm) showed the highest efficacy, reducing the mite infestation by 17.79% compared to the control. The glycerin-oxalic acid strips of paper-cellulose (2.3 mm) were also effective, achieving a 17.05% reduction in mite levels. These results provide valuable insights for beekeepers seeking alternative and sustainable methods for controlling infestations.
由于虫害程度高导致蜂群数量减少，因此有必要开发新的防治方法。本研究评估了甘油草酸条和精油在防治方面的有效性。该实验于2022年在科斯蒂恩布罗德畜牧研究所下属的德贝莱茨实验蜂场进行。将六个实验组（每组用不同制剂处理）与未处理蜂群的对照组进行比较。处理方法包括使用Beevital Hiveclean（每群20毫升）、Varro Red（每框2毫升）、硝酸铵条（1.3毫米）、甘油草酸条（1.3毫米）以及纸质纤维素（2.3毫米）或纤维素棉（2.3毫米）的甘油草酸条。对照组不做处理。由纤维素和棉制成的甘油草酸条（2.3毫米）显示出最高的功效，与对照组相比，螨虫感染率降低了17.79%。纸质纤维素（2.3毫米）的甘油草酸条也有效，螨虫数量减少了17.05%。这些结果为寻求控制虫害的替代和可持续方法的养蜂人提供了有价值的见解。
