The Colorado potato beetle, Leptinotarsa decemlineata (Say), is one of the most destructive pest species to have developed resistance to most chemical insecticides. We determined the composition and evaluated the potential of Tanacetum parthenium L. and Tanacetum vulgare L. (Asteraceae family) essential oil (EO) application as an alternative eco-friendly control strategy against L. decemlineata. We assessed the antifeedant activity for L. decemlineata larvae and adults by estimating the damage to potato leaves treated with three concentrations of EOs dissolved in ethanol (0.125, 0.25 and 0.5%). Results showed that T. parthenium EO was more effective against larvae, and T. vulgare was more effective against adults. In an olfactometer assay, the time required to choose an untreated leaf disc did not depend on the Tanacetum species, or life stage examined. However, the concentration of EO exhibited a significant effect on the behaviour of both developmental stages. At higher EO concentrations, both third instar larvae and adults require less time to choose an untreated leaf disc. Additionally, T. parthenium EO provoked more rapid movement away from the treated leaf disc than T. vulgare, especially at the highest concentration. Successful modification of L. decemlineata behaviour by the two Tanacetum oils suggests that they possess the potential for use in potato protection.

Tanacetum parthenium (L.) 和 Tanacetum vulgare (L.) 精油对 Leptinotarsa decemlineata (Say) 的驱避活性

科罗拉多马铃薯甲虫,小蠊(说),是对大多数化学杀虫剂产生抗药性的最具破坏性的害虫物种之一。我们确定了成分并评估了其潜力小茴香土地杂草L.(菊科)精油 (EO) 应用作为替代的环保控制策略L. decemlineata. 我们评估了拒食活动L. decemlineata通过估计用溶解在乙醇中的三种浓度的 EO(0.125、0.25 和 0.5%)处理的马铃薯叶片的损害来估计幼虫和成虫。结果表明T.partheniumEO 对幼虫更有效,并且T. vulgare对成年人更有效。在嗅觉仪测定中,选择未经处理的叶盘所需的时间不取决于紫檀检查的物种或生命阶段。然而,EO 的浓度对两个发育阶段的行为都有显着影响。在较高的 EO 浓度下,三龄幼虫和成虫都需要较少的时间来选择未经处理的叶盘。此外,T.parthenium与处理过的叶盘相比,EO 引发了更快的运动远离处理过的叶盘T. vulgare,尤其是在最高浓度时。修改成功L. decemlineata两人的行为紫檀油表明它们具有用于保护马铃薯的潜力。
