Some kind of Insect on my Plumerias

I am in Houston, Tx.

I need some advice on Plumeria Pests. This is the second year that I have grown them. The first year they were just cuttings. This year most are in the ground. The plumies in the front have orange all over the bottom of the leaves. What is this pest !!

I have tried to spray with a systemic insecticide. I hate using insecticides so I tried Neem which didn't work at all. (nothing seems to work) Is the orange an effect of spider mites. I keep spider mites off of my other plants with orange peels. Should I pull these infected leaves off of the plant.

Does anyone have any suggestions. They would be much appreciated. Thanks in advance. Carol

Insecticide won't work if it's a disease. Can you post a picture of the orange you see? Could be a disease -- rust.

Thanks, I also posted on the plumeria site. They said it was rust - exactly what you said. I have been treating for the wrong thing. Thanks for the valuable info. Carol

carol, next time you observe a problem with your plants, try to identify it BEFORE you spray. Using pesticides of any kind (fungicides or insecticides, for example) without knowing for sure who the enemy is, isn't the way to go. For a lot of reasons.

You can always find a pack of good detectives here in the GardenWeb forums.
