I recall hearing about the introduction of the prickly pear cactus
to Australia.  It ran out of control, and was a serious nuisance to
ranchers.  The investation was controlled by introduction of a moth
whose caterpillar ate the cactus.

Isn't the Japanese beetle an immigrant in north america?

Let's also not forget syphilus and smallpox.
