鸡皮螨（Dermanyssus gallinae）是一种寄生在鸡血上的螨虫，对家禽业构成了相当大的威胁。鸡戎杆菌侵染可对宿主鸟类造成过多的有害影响，包括产蛋量减少和贫血。拟除虫菊酯类杀虫剂是对付这一问题的主要手段，并已显示出很高的功效。然而，近年来鸡腹直蝇对这些化学物质表现出抗药性，导致其死亡率显著下降；因此，除使用化学药剂外，还应采取综合防治策略，以实现对该螨的可持续防治。本研究证实，利用高压脉冲放电可以有效控制鸡粉螨，并且各种电气参数具有控制螨所需的最优值。高压脉冲引起的螨虫体表的变化与热引起的变化相似，但体表的元素组成没有变化，这表明外骨骼内部流动的电流引起了组织的变化。相比之下，高压脉冲杀灭螨的效果明显优于紫外线或臭氧，在短短30秒内杀灭螨的效果可高达95%。
Dermanyssus gallinae, a parasitic mite that subsists on the avian blood of chickens, poses a considerable threat to the poultry industry. D. gallinae infestation can result in a plethora of detrimental effects for the host birds, including decreased egg production and anemia. Pyrethroid pesticides have been the primary means of combating this issue and have demonstrated high levels of efficacy. However, in recent years, D. gallinae has exhibited resistance to these chemicals, resulting in a marked decrease in their mortality; thus, an integrated control strategy in addition to the chemical use should be required for the sustainable control of this mite. This study confirms that D. gallinae can be effectively controlled through the utilization of high-voltage impulse discharges and that various electrical parameters possess optimal values that are required for mite control. The alterations in the body surface of the mite caused by high-voltage impulses were akin to those caused by heat, but no alteration in the elemental composition of the body surface was observed, suggesting a change in organization caused by currents flowing inside the exoskeleton. Comparatively, the mite control efficacy of high-voltage impulse was found to be substantially superior to that of ultraviolet light or ozone, with up to 95% more mites being killed in as little as 30 seconds.
