Cyantraniliprole is a novel anthranilic diamide insecticide that acts on a broad spectrum of insect pests, exclusively by activating their ryanodine receptors. Cyantraniliprole is very effective against whitefly and it presents a favorable ecotoxicological profile. In this study, the baseline susceptibility to cyantraniliprole of Trialeurodes vaporariorum populations from the Mediterranean area was established in nymphal systemic uptake bioassays.
The bioassay data showed that the susceptibility to cyantraniliprole varied among the strains collected across the Mediterranean basin. The 50% lethal concentration (LC ) range of cyantraniliprole for 16 field populations was from 0.017 to 0.194 mg L , a 11.4-fold natural variability between the least and most sensitive populations. These LC values are similar to those reported in a previous study of the use of cyantraniliprol against another species of whitefly, Bemisia tabaci [LC = 0.048 (0.034-0.063) mg L ].
The current study confirmed the effectiveness of cyantraniliprole against T. vaporarioum strains, adding to the evidence that cyantraniliprole is a promising tool for use in integrated pest management programs. Future shifts in the susceptibility of whitefly field populations to cyantraniliprole may be documented according to the baseline susceptibility range of the populations tested in this research. © 2018 Society of Chemical Industry.
氰氟虫腙是一种新型邻苯二甲酰胺类杀虫剂,通过作用于昆虫肌浆网钙释放通道的ryanodine 受体,对多种害虫表现出广谱杀虫活性。氰氟虫腙对白粉虱具有很好的防治效果,且具有良好的生态毒理学特性。本研究采用幼虫体系统摄入生物测定法,测定了来自地中海地区烟粉虱种群对氰氟虫腙的基础敏感性。
生物测定数据表明,不同地理种群对氰氟虫腙的敏感性存在差异。16 个田间种群对氰氟虫腙的 50%致死浓度(LC )范围为 0.017-0.194 mg/L,最敏感和最不敏感种群之间的自然变异性为 11.4 倍。这些 LC 值与先前使用氰氟虫腙防治另一种粉虱——烟粉虱的研究结果相似[LC 50 = 0.048(0.034-0.063)mg/L]。
本研究证实了氰氟虫腙对烟粉虱种群的有效性,进一步证明氰氟虫腙是综合虫害管理计划中一种很有前途的工具。未来,田间烟粉虱种群对氰氟虫腙的敏感性可能会根据本研究中测试种群的基础敏感性范围发生变化。 © 2018 英国化学学会
