I found this deformation...almost like galls...on some young seedlings of hoya I have. When the 'spot' is picked off, there is a 'dimple' in the swollen stem. Have you ever seen this? I have about 40 of these seedlings, and the affect is on about 1/4 of them....it is only on the end of new growth and, needless to say, the new leaves are totally deformed.

TIA
Carol

Am taking it to the plant pathologist(at the U. of H.)tomorrow...will post results....

Actually, I found out it is a soft bodied scale...first time found in Hi...and I killed it (has not returned) with a drench of BATS.

Bayer Advanced Tree & Shrub, a really good systemic insecticide (used at a seriously diluted rate compared to what you would use on a tree or shrub)

OK. Active ingredient imidacloprid. Just had never seen it referred to as BATS...

Works great on lots of things, but not armored scale or cottony cushion scale...
