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.
