ABSTRACT The Rhipicephalus microplus is an important ectoparasite of livestock as it results in loss to the producer. The present study analyzed the effects of ozone gas, a fluid with acaricidal potential, on this species of cattle tick. Engorged females of R. microplus were divided into two groups: control, oxygen and ozone groups. The results indicated that ticks in the control and oxygen groups maintained the oviposition process intact. Females exposed to the ozone gas died before eggs were deposited and damage on the cuticle was observed, proving that the ozone gas had an acaricidal effect on the ticks.

臭氧对产蛋前充血的小圆头鱼（Acari：Ixodidae）雌性的影响

摘要 Rhipicephalus microplus 是一种重要的家畜体外寄生虫，因为它会导致生产者的损失。本研究分析了臭氧气体（一种具有杀螨潜力的流体）对这种牛蜱的影响。充血的 R. microplus 雌性被分成两组：对照组、氧气组和臭氧组。结果表明，对照组和氧组中的蜱虫保持了完整的产卵过程。暴露于臭氧气体的雌性在卵沉积之前死亡，并观察到角质层受损，证明臭氧气体对蜱有杀螨作用。
