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.
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.

How Is It Spread?
In the spring, females lay their eggs along the midribs of emerging folded leaflets. Eggs hatch in 8-9 days and mature within a month, coinciding with the emergence of new leaves on royal palms. Multiple generations of royal palm bugs occur each year.
