Main Question or Discussion Point

The brown marmorated stinkbug (Halyomorpha halys) is an introduced plant pest from Asia that has invaded parts of the US (first seen in 1998), Europe, and perhaps other places.
Since it was introduced with out its natural predators and can feed off a variety of crops plants it has done quite well in the US causing as much as 37 million dollars of crop damage to Mid-Atlantic apple growers.
In the winter it can also invade homes to overwinter and make itself annoying to people directly.

Scientists have been investigating how it might be controlled by the intentional introduction of of other insects that would predate upon it.
An important candidate species is the samurai wasp (Trissolcus japonicus), a parasitoid wasp which lays its eggs in the eggs of the marmorated stinkbug and eats them from the inside out.
Normally, in the US, such introductions would have to be carefully tested to ensure the introduced predator would not have unintended effects on other parts of the environment (many such screw-ups are well documented, for example).

However, this Science magazine news article describes how the samurai wasp has recently turned up in several places in the US, producing naturally occurring field tests of its effects on the stinkbug and the larger environment.

Hope this guess doesn't count as a personal theory, but it seems to me that the stink bug problem waxes and waned in my area. So maybe potential predators notice and adapt. It takes a little while for a new restaurant to gain traction.

I've thought about this for a while, than got distracted.
I like @Russ-waters post and want to point out how he makes his point and avoids presenting it as a personal theory:
Its not a personal theory for a numbers of ways in which it is presented:
  • wording of the idea with words of uncertainty (hope, guess, maybe)
  • presents an alternative explanation without saying it has to be a certain way
  • has a link to something relevant

What is a personal theory around here seems to be a common topic of discussion.
Russ provides a good example of what's not, but is exploring things a bit.
This is a good crisp (short) thing.

It could be a how to for people on making a point without expressing it as a personal theory.
