The soybean aphid is also an example of an invasive exotic  species which 
has a serious economic impact.   In addition, soybean  aphids winter on 
Eurasian buckthorn, one of the top problem invasive exotic  plant species in Iowa.
 
Our national policies and regulations for keeping out potential and  known 
invasive exotics are very inadequate, and so is enforcement.    We can't 
keep them all out, but we could be doing a better job than we are  now.
