Vanessa atalanta

来自德国、英国、西班牙、意大利和匈牙利的研究人员开发了一种评估转博狗官方中文德州扑克论坛玉米对非靶向节肢动物影响的数学模型。研究人员选择了两种被保护的蝴蝶品种(Inachis io和Vanessa atalanta)和钻石背蛾(Plutella xylostella)进行评估。为了尽可能的提高模型的可靠性,计算过程中选择了欧洲11个种植转博狗官方中文德州扑克论坛玉米Mon810的代表性区域。模型计算显示种植转博狗官方中文德州扑克论坛玉米对蝴蝶和蛾的影响非常小。在所有地区中孔雀蝶和上将蝶的最大死亡率小于1/1572,钻石背蛾的最大死亡率为1/392。两种蝴蝶品种的平均死亡率为1/5000,钻石背蛾的平均死亡率为1/4367。

这项研究发表于Proceedings of the Royal Society B,作者在文章中写道:“我们的结果表明以往的评估过于谨慎,死亡率和亚致死率仅是原有值的1/4。”

Genetically modified (GM) maize MON810 expresses a Cry1Ab insecticidal protein, derived from Bacillus thuringiensis (Bt), toxic to lepidopteran target pests such as Ostrinia nubilalis. An environmental risk to non-target Lepidoptera from this GM crop is exposure to harmful amounts of Bt-containing pollen deposited on host plants in or near MON810 fields. An 11-parameter mathematical model analysed exposure of larvae of three non-target species: the butterflies Inachis io (L.), Vanessa atalanta (L.) and moth Plutella xylostella (L.), in 11 representative maize cultivation regions in four European countries. A mortality–dose relationship was integrated with a dose–distance relationship to estimate mortality both within the maize MON810 crop and within the field margin at varying distances from the crop edge. Mortality estimates were adjusted to allow for physical effects; the lack of temporal coincidence between the susceptible larval stage concerned and the period over which maize MON810 pollen is shed; and seven further parameters concerned with maize agronomy and host-plant ecology. Sublethal effects were estimated and allowance made for aggregated pollen deposition. Estimated environmental impact was low: in all regions, the calculated mortality rate for worst-case scenarios was less than one individual in every 1572 for the butterflies and one in 392 for the moth.
