: I live in the Jacksonville, FL area

: infesting the underside of the

: several sheltering trees. It's now
: in full sun about 6 hours a day.
: Any thoughts as to the problem?
: Treatment?

Those look like long, soft shelled scales. I would read my article on Asian scale on my website,(which is linked on the header) but mainly you want to spray the plant with a systemic, like Orthene, or Cygon. You can also use horticultural oil which smothers the insects when you spray them if you don't like using nasty chemicals, but a systemic works a whole lot better.
