oh yes! a definite problem, these buggers will inject a hormone to make the plant grow the way they want it, that means dwarfism!

I had this problem and now at any sign of the winged white ones I will spray the underside of the leaves of the entire plant with malathion. I have done this twice so far this year, kills them right away. Don't know if this is a restricted chemical, now...... but I have some from years ago.
good luck

Thanks I hope I can find some.
