Tipuanas are a very popular landscape tree throughout Southern California. Despite their hardiness they are adversely affected by an insect called the Tipu Psyllid. There are over 160 psyllid species that occur on native or introduced landscape plants in California, the Tipu Psyllid was first documented in California in Carlsbad in 2008. Most of the psyllid species are pests of crops such as citrus, olive, pear, potato, and tomato with each kind of psyllid affecting only one plant species. Tipu Psyllid Adults and Nymphs suck the juices (phloem) from leaves causing injury (yellow, curl) and leaves that pre‐maturely fall during their normal growing period. Heavily infested trees will become covered in masses of wax and sticky honeydew which is produced by the nymphs. This dew will fall on nearby objects (cars, sidewalks, furniture, etc.) causing unsightly and sticky staining.
There are preventative treatments available that will help reduce psyllid populations, reducing the amount of sticky honeydew that’s produced and improving the overall health and appearance of the tree. Control is most effective when the insect is in the early stages of it’s development.
