Female olive psyllids lay eggs on new shoots, leaves, and buds JohnsonZalom et al. Population densities greater than 20 nymphs per inflorescence can cause such losses.
When nymphal colonies are on the apical parts of young shoots, sap loss is not important. Populations in Riverside County have only been found from Temecula to Wildomar.
In the United States, olive psyllid infestations are mostly found on ornamental olive wuphyllura Johnson It is best to monitor for the first generation of olive psyllids because the reduction of that generation can substantially reduce population levels of the second generation.
Maslinina buha – Euphyllura olivina Costa, Hemiptera: When colonies are on euphjllura, the level of sap loss is directly proportional to psyllid numbers and this could affect the amount of fruit that is set. The life cycle is about 3 months depending on temperature.
As its common name suggests, the olive psyllid Figure 1 is found within the family Psyllidae, which contains over genera Myers et al.

Plant suckers shoots at the base of the tree, if they have not been removed, should be inspected for olive psyllids M. Contributors own the copyright to and are solely responsible for contributed content. Additionally the accumulation of waxy secretions from olive psyllids may reduce yield by causing premature flower drop Johnson et al.
Secretions made by Euphyllura olivina Costa on buds of an olive tree, Olea europaea L. Olive psyllid, Euphyllura olivina Costanymphs on olive stem. Methods of monitoring include using sticky traps, agitating foliage to count fallen adults, and careful inspection of plant parts for eggs, nymphs, and adults Kabashima et al.
Adult olive psyllids are dull green to gray in color with slightly black-mottled forewings. Appraising the threat of olive psyllid to California table olives.
In southern California, psyllid numbers decline after June, most likely because it is hot. Since in Croatia olive psyllid generally causes little damage to the olive, chemical control, except in rare cases, is not recommended.
Nymphs are flat, green to tan, and secrete a white waxy coating that covers the entire colony. The highest populations observed have been in the cities of Carlsbad and San Diego. Honeydew, also produced by nymphs and adults, can lead to sooty mold development on the surface of the host plant Johnson The success rate for olive psyllid development was highest for the Haouzia variety Meftah et al.

How to Manage Pests
Olive Psyllid, Euphyllura olivina Costa Hemiptera: UC pest management guidelines: Additionally, olive psyllid may be able to impact the production of olive oil if it can expand its northern distribution along the cooler California coast, where significant amounts of oil are produced.
This only becomes a problem when olive psyllids are on inflorescences flower clusterswhich ultimately affects fruit production. Efforts were made to establish colonies of one parasitoid collected in Spain, but euphylluga were unsuccessful.
Adult olive psyllid, Euphyllura olivina Costa. The accumulation of honeydew on foliage provides a substrate for development of sooty mold Figure 3which can potentially block sunlight and inhibit photosynthesis, or lead to olifina aging of leaves that causes the leaves to drop Laemmlen Observation of arthropod populations during outbreak of olive psyllid Euphyllura olivina in Tunisian olive groves. If you need expert professional advice, contact your local extension office. Olive psyllid feeds on olive, Russian olive Elaeagnus angustifolia and mock privet Phillyrea latifolia.
Euphyllura olivina Costa Hemiptera: Because the secretions complicate control strategies, insecticides should target the first generation euphyllurz avoid problematic second generation infestations Kabashima et al. Euphyllura olivina can be confused with Euphyllura straminea because they are similar in appearance.
I am curious how and when and from where the species arrived on the island. The olive psyllid, Euphyllura olivina Costabelongs to the superfamily Psylloidea, which consists of six families. Management Back to Top Host plants need to be monitored for olive psyllid populations to prevent infestations from establishing in new locations.
The aestivating olive psyllids hide in cracks of the trunk of the host plant Zalom et al.
