As Dennis the Menace's mother said at the pet store "One rabbit yes,
two rabbits NO." Many introductions of organisms that have become
noxious pests, were originally very limited. The classic one crate
on one fruit boat. I wonder if the Chestnut blight could be traced to
a point source introduction. I do not think that the scale of introduction
is *necessarily* the problem. If the organism is going to get established
then the difference in range between a large scale introduction and a
small scale introduction may only be a matter of time. Hence the
percieved need in some instances (i.e. medfly) for erradication. There is
probably a difficulty in scaling up. I seriously doubt that the USDA
fostered the release of these insects without experimental investigation
on a very limited scale. This shows that even when care is taken there
are aspects of large scale interactions which are not predictable
from small scale experiments. Ultimately both small and large scale
introductions (the latter more so) involve a certain amount of
let-it-rip-and-hope-for-the-best.
