| 7 | Relative fitness of susceptible and Cry1A.105/Cry2Ab2-single-/dual-protein-resistant Helicoverpa zea (Boddie) (Lepidoptera: Noctuidae) on non-Bt diet and a diet containing a low concentration of two proteins显示文摘Helicoverpa zea(Boddie)is a destructive agricultural pest species that is targeted by both Bacillus thuringiensis(Bt)maize and cotton in the United States.Cry1A.105 and Cry2Ab2 are two Bt proteins expressed in a widely planted maize event MON 89034.In this study,two tests(Test-Ⅰ and Test-Ⅱ)were conducted to evaluate the relative fitness of Bt-susceptible and-resistant H.zea on non-Bt diet(Test-Ⅰ and Test-Ⅱ)and a diet containing a mix of Cry1A.105 and Cry2Ab2 at a low concentration(Test-Ⅱ only).Insect populations evaluated in Test-Ⅰ were two Bt-susceptible strains and three Bt-resistant strains(a single-protein Cry1A.105-,a single-protein Cry2Ab2-,and a dual-protein Cry1A.105/Cry2Ab2-resistant strains).Test-Ⅱ analyzed the same two susceptible strains,three backcrossed-and-reselected Cry1A.105/Cry2Ab2-single-/dual-protein-resistant strains,and three F1 heterozygous strains.Measurements of life table parameters showed that neither the single-nor dual-protein Cry1A.105/Cry2Ab2 resistance in H.zea was associated with fitness costs under the test conditions.The single Cry protein resistances at a concentration of a mix of Cry1A.105 and Cry2Ab2 that resulted in a zero net reproductive rate for the two susceptible strains were functionally incomplete recessive or codominant,and the dual-protein resistance was completely dominant.The lack of fitness costs could be a factor contributing to the rapid revolution of resistance to the Cry proteins in this species.Data generated from this study should aid our understanding of Cry protein resistance evolution and help in refining IRM programs for H.zea. | Shucong Lin Graham Head Paula Price Ying Niu Fangneng Huang | 2023 | Insect Science2023，30，2： | 0 |
| 8 | Susceptibility of field populations of sugarcane borer from non-Bt and Bt maize plants to five individual Cry toxins显示文摘甘蔗 borer, Diatraea saccharalis (F.) ,转基因的玉米的一个主要目标正在表示杆菌 thuringiensis (Bt ) 蛋白质在南美洲和美国中间南方的区域。在目标害虫人口的抵抗开发是对 Bt 庄稼的持续使用的主要威胁。在我们在 2009 的地试用,从 D 的实时 borers 和植物损害的一个重要数字。saccharalis 在一根试验性的 SmartStax 玉米线被观察。这研究的目的是估计 D 的二张地人口的相对危险性。从 non-Bt 和 Bt 玉米收集的 saccharalis 种包含 SmartStax 特点到五单个叫喊蛋白质。五 Bt 蛋白质包括了在 SmartStax 玉米植物被表示的二蛋白质(Cry1A.105 和 Cry2Ab2 ) 和没在 SmartStax 被生产的三另外的普通 Bt 蛋白质(Cry1Aa, Cry1Ab 和 Cry1Ac ) 。在在领域集合以后的第四代的 Bt 节食的幼虫的死亡和生长抑制被评估在在节食的出生不满一月的婴儿的版本以后的 7 天出现。实验室生物鉴定证明为 Cry1A.105 的 50% 致命的集中(LC50 ) 价值和为人口的 Cry2Ab2 从 Bt 植物发源是 3.55 褶层和 1.34 褶层更大分别地,从 non-Bt 收集的人口比那些种。相对从 non-Bt 植物的人口,相反,从 Bt 取样的人口的 LC50 种分别地是 3.85- , 2.5 褶层和对 Cry1Aa, Cry1Ab 和 Cry1Ac 更敏感的 1.64 褶层。结果没提供清楚的证据断定 D 的观察的地幸存。Bt 植物上的 saccharalis 与抵抗的增加的层次被联系。 | Fangneng Huang Mukti N.
