Frank,
The only problem I've seen with stink bugs are tomato related. They will pierce the fruit while it's still green, causing a bruise and for the fruit to not ripen correctly or at all. I would assume, all stink bugs to be a bad thing and to get rid of them as best you can. The traps that they sell for them, were a waste of money for me. I've had to resort to getting up early in the morning and tapping them into a jar of soapy water. Hope this helps.
