摘要

本研究评价了天然萜烯芳樟醇对微头绦虫幼虫的杀螨活性。选取来自不同牛场的4个具有杀螨剂抗性历史的蜱虫种群。采用幼虫包试验法(LPT)测定了芳樟醇、氯氰菊酯和芳樟醇与氯氰菊酯联用的致死浓度LC50和LC90。芳樟醇浓度为0.0975 ~ 50%,氯氰菊酯浓度为0.01% ~ 3%。结果表明,单独芳樟醇的LC50值在不同种群中变化,范围为0.5 ~ 4.33%,LC90值在2.57 ~ 7.61%之间。当芳樟醇与氯氰菊酯联用时,达到LC50和LC90所需的氯氰菊酯浓度显著降低(p≤0.05)。结果表明,芳樟醇可提高氯氰菊酯的杀螨效果。因此,将芳樟醇与氯氰菊酯结合使用可能对蜱虫管理策略有价值,特别是在减少对这些高剂量杀螨剂的依赖方面。

Acaricidal efficacy of the monoterpene linalool against the cattle tick Rhipicephalus microplus and its synergistic potential with cypermethrin.

This study evaluated the acaricidal activity of the natural terpene linalool against Rhipicephalus microplus larvae. Four tick populations from different cattle farms with a history of acaricide resistance were selected. The Larval Packet Test (LPT) was used to determine the lethal concentrations (LC50 and LC90) of linalool, cypermethrin, and the combination of LC50 linalool and cypermethrin. Linalool was tested at concentrations ranging from 0.0975 to 50%, while cypermethrin was tested between 0.01% and 3%. The results demonstrated that linalool alone had LC50 values varying across the populations, ranging from 0.5 to 4.33%, and LC90 values ranging from 2.57 to 7.61%. When linalool was combined with cypermethrin, the required concentrations of cypermethrin to achieve LC50 and LC90 were significantly reduced (p ≤ 0.05). This reduction in cypermethrin dosage was observed across all tested populations, indicating that linalool can enhance the acaricidal efficacy of cypermethrin. Integrating linalool with cypermethrin could therefore be valuable for tick management strategies, particularly in reducing reliance on high doses of these acaricides.

期刊介绍: Experimental and Applied Acarology publishes peer-reviewed original papers describing advances in basic and applied research on mites and ticks. Coverage encompasses all Acari, including those of environmental, agricultural, medical and veterinary importance, and all the ways in which they interact with other organisms (plants, arthropods and other animals). The subject matter draws upon a wide variety of disciplines, including evolutionary biology, ecology, epidemiology, physiology, biochemistry, toxicology, immunology, genetics, molecular biology and pest management sciences.
