The olive psyllid (Euphyllura olivine) is in the order Hemiptera and family Psyllidae. This pest is native to Europe and the Middle East and has become established in California. However, the olive psyllid has not yet been introduced into Florida. With Florida’s growing olive industry, it’s very important that growers take precautions against introducing this pest by ensuring nursery stock is free of this pest.
One indicator of olive psyllid infestation is the presence of a whitish, waxy secretion on plant and covering nymphs of the psyllid. In addition, this pests secretes honeydew which will lead to the development of sooty mold on infested plants. This pest feeds on olive trees and infestations are most commonly found on ornamental olive trees. Insecticides are most useful before the presence of the waxy secretion on the plant. Also, the olive psyllid has been known to be parasitized by a few insects including endoparasitic wasps, minute pirate bugs, lacewings, and lady beetles.
