Royal Palm Bug

What is Royal Palm Bug?

Royal Palm Bug, Xylastodoris luteolus, is a destructive insect pest of Cuban royal palms in the southern third of Florida.  This insect feeds on freshly opened leaves, giving infested trees a yellow, tattered appearance.  Although royal palm bug is rarely fatal, its damage can be unsightly and can quickly warrant treatment.

Treatment Strategy

Optrol ™ is a long lasting, soil applied, systemic insecticide that can be applied at virtually any time.  With just one application that lasts a full year in the tree, Optrol™ is able to move into the leaves and control royal palm bug where it is feeding.  Preventative treatments are best applied in the winter (November-February) when insect activity is reduced to protect newly emerging foliage in the spring.  Reapply annually to maintain protection.
