Despite its common name, not seagrape (Coccoloba uvifera) does not produce grapes, it is not growing in the sea. It is a tree reaches 30 feet high and wide and is often found along sidewalks and in the privacy hedges on private property. The plant thrives in hot, humid weather and can grow indoors as a bonsai plant. The tree has few pest problems, but does it cause serious problems for farmers.
The seagrape drill is a butterfly native to the same areas where seagrape thrives. The moths’ larvae bore into the bark and feed on the trees from the inside out, the hollowing out of industry. This results in the large leaves turn yellow or red. Hollowed branches tear easily and the holes through which the probes indicate the branch often leak frass, insect excrement. This material is usually dark green, brown or black.
Seagrape borer infestations are kept in check by natural predators, including larger insects. The damage is usually minimal. The only time it really effected the health of the tree is, if the infestation is growing out of hand or the little tree with young established wood. Prune branches and twigs signs of borer activity. If the infestation is large, treat it with a general purpose insecticide. Note that an insecticide kills the natural enemies. Apply it directly to where you know there are drills.
Nipple galls are caused by various natural outdoor organisms. Some are the natural enemies of the corn borer. The most frequent damage nipple causes small red nipple flecking the upper surfaces of the leaves. The unevenness, as the insects lay their eggs, and usually have little to no effect on the actual health of the tree. In extreme cases, result in the bile leaves fall from the tree, but there are no long-term harm.
Most growers choose not to treat bile because they do so little damage to the plant itself. If you do treat the gall to use insecticides to kill the bugs in their adult life stage. This is most effective if you can determine what type of insect caused the bile, so that species-specific chemicals. If you can not identify your insect, consult a professional to a garden center, nursery or counseling service for help.
