在实验室条件下研究了等离子体处理自来水（PTW）对粉蚧（Planococcus citri）侵染的可能治疗效果。在夹竹桃上生长的粉蚧在转移到培养皿后使用PTW进行处理，从而避免了在原位研究中可能发生的缓冲效应。当用介质阻挡放电处理自来水几分钟（1,3,5和10分钟）时，可以确定水的明显酸化，在处理10分钟后导致pH值为1.8。将处理过的自来水样品的效果与传统酸化水的效果进行了比较。自来水的经典酸化是用硝酸和盐酸进行的，以观察酸的盐的任何可能的影响。PTW的应用表明，其死亡率约为10%。经过24小时的观察期，其效果达到90%。PTW作为一种环保的传统农药替代品或补充，有望用于小规模农民或温室生产的小型植物和商品的处理。
The efficacy of plasma-treated tap water (PTW) for the possible treatment of a mealybug (Planococcus citri) infestation was studied under laboratory conditions. Mealybugs growing on Nerium oleander have been treated using PTW after being transferred to Petri dishes, thus avoiding possible buffering effects that might occur in an in-situ study. When treating tap water with a dielectric barrier discharge for several minutes (1, 3, 5 and 10 min) a distinct acidification of the water can be determined, resulting in a pH value of 1.8 after 10 min treatment. The efficacies of the treated tap water samples were compared to the efficacies achieved using classically acidified water. The classical acidification of tap water was carried out using nitric acid and hydrochloric acid to see any possible influences of the salt of the acid in question. The application of PTW revealed high mortality rates of approx. 90% after an observation period of 24 h. PTW appears promising for the treatment of smaller plant stock and commodities as produced by small scale farmers or in greenhouses as an environmentally friendly substitute or supplement to conventional pesticides.
