I am sorry for this delayed reply to your gardening question. We are transitioning to a new Q&A system and your question was unfortunately lost in the transition. I have discovered it now and hope this reply is not too late to be of help.
The only pest I can think of would be scale insects which appear as white spot on the upper leaf surfaces usually along the leaf veins. These can be controlled with horticultural oil sprays if coverage is very good. Systemic insecticides can also be helpful depending on the product. I would wait to apply any product until I saw that an insect infestation was starting.
Thanks for the question. Please stop in again soon!
