The increasing number of exotic organisms spreading worldwide is an all too familiar tale. Developing and prioritizing programs to manage invasive species is further complicated by “lag times” between arrival of an exotic organism and its possible emergence as a serious pest.
I will discuss how these lag times complicate using current field observations to predict potential long term impacts for both invasive and native species. I will also demonstrate how my work with three plant-insect systems illustrates some ways in which native insects can be used as tools to explore and refine questions regarding the long term dynamics of species invasions and biological control.
