I've seen whiteflies on my spruce but not my tomatoes --but I think
they are part of the problem, I just have not caught them in the act.
What I see most often are little sucking bugs attached to the trunk,
they look like mosiquitos, but smaller. Can they be young, non-adult
I don't know but I had what sounds like the same thing. To me they
almost looked like gnats - really tiny little bugs. I sprays with
BugBegone. It worked. Then I used a systemic called Admire. The
bugs haven't come back.
I had what I assume were white flies on my zucchini (several blocks
away from my tomatoes) and used the BugBegone (a bit too generously)
and the Admire. No more white flies.
