The fall armyworm, Spodoptera frugiperda (Sf), is a polyphagous lepidopteran herbivore that consumes more than 80 plant species, including many economically important crops, such as corn, soybeans, and sorghum. While already a serious pest in the Americas, it was recently introduced into Africa, India, and China. Because of its high economic costs in the New World and the continent-wide damage potentials in Africa, research to develop advanced pest management technologies is necessary. We are supporting this need by developing novel, next-generation insect cell lines from targeted tissues. Cell lines, such as these, will boost insecticide discovery programs and lead to innovative pest management solutions. Here, we report on the establishment of 16 new cell lines from larval S. frugiperda tissues: nine from the central nervous system, three from the aorta, and four from the testes. We confirmed the identities of the cell lines by DNA amplification fingerprinting polymerase chain reaction, determined their doubling times from growth curves, and described cell types via microscopy. We also developed 16 sublines from three neuronal cell lines.
秋粘虫,Spodoptera frugiperda(Sf),是一种多食性鳞翅目植食性昆虫,它可以食用 80 多种植物,包括许多经济上重要的作物,如玉米、大豆和高粱。虽然它在美洲已经是一种严重的害虫,但最近它被引入了非洲、印度和中国。由于它在新世界造成了很高的经济成本,并且在非洲具有大陆范围的破坏潜力,因此需要研究开发先进的害虫管理技术。我们正在通过从目标组织中开发新型的下一代昆虫细胞系来支持这一需求。这些细胞系将促进杀虫剂的发现计划,并为创新的害虫管理解决方案提供支持。在这里,我们报告了从幼虫 Sf 组织中建立的 16 种新的细胞系:9 种来自中枢神经系统,3 种来自主动脉,4 种来自睾丸。我们通过 DNA 扩增指纹聚合酶链反应(PCR)确认了细胞系的身份,通过生长曲线确定了它们的倍增时间,并通过显微镜描述了细胞类型。我们还从 3 种神经元细胞系中开发了 16 种亚系。
