The red-imported fire ant is one of the world's worst invasive species and costs associated with control, management, and agricultural losses due to this insect exceed a billion dollars a year in the United States. Despite arriving in the southeastern United States from South America over 70 years ago, we still know very little about the what areas are vulnerable to this invader, what delineates species boundaries in the fire ant species complex, and which new species of fire ant may become invaders in the future. We will integrate molecular and ecological techniques to address these outstanding questions. This information will be of enormous scientific value, as we investigate the nature of species and the delineation of species boundaries, as well as of practical value for understanding the full invasive potential of the highly damaging fire ant pest species and for conceiving novel management strategies for these pests. A central societal issue to be addressed in the broader impacts of the proposed project is the critical shortage of well-trained science teachers in primary and secondary schools in the U.S.A. Two strategies will be employed to encourage students to consider science education/scientific research as career options, one involving students at public high schools in northern Georgia and central Illinois, and the other involving undergraduates.

红火蚁是世界上最严重的入侵物种之一，在美国，与控制、管理和农业损失相关的成本每年超过10亿美元。尽管70多年前从南美洲来到美国东南部，但我们仍然对哪些地区容易受到这种入侵者的影响，在火蚁物种复合体中划分物种界限的内容以及哪些新的火蚁物种可能成为未来的入侵者知之甚少。我们将结合分子和生态技术来解决这些悬而未决的问题。这些信息将具有巨大的科学价值，因为我们调查物种的性质和物种边界的划分，以及了解高度破坏性的火蚁害虫物种的全部入侵潜力和构思这些害虫的新管理策略的实用价值。一个中心的社会问题，以解决更广泛的影响，拟议的项目是严重缺乏训练有素的科学教师在小学和中学在美国将采用两种策略，鼓励学生考虑科学教育/科学研究作为职业选择，一个涉及学生在公立高中在北方格鲁吉亚和伊利诺伊州中部，另一个涉及本科生。
