Honeydew, also produced by nymphs and adults, can lead to sooty mold development on the surface of the host plant Johnson Currently, the olive psyllid euphlylura not found in Florida, but it does have the potential to spread to new locations via olive tree importation.
How to Manage Pests
Nymphs Figures 4 and 5 have a flattened, light green and white body and reddish-purple eyes. Contributed by Alex Bairstow on 21 May, – 5: Official Journal of the International Olive Council Both immature and adult olive psyllids excrete honeydew due to their inability to utilize all of the sugar and eupyllura in the plant sap ingested during feeding. It is unclear at this time euphylulra the distribution of Euphyllura olivina will significantly expand beyond San Oliviha and Orange Counties.
Text and photos provided by: These species have varying and somewhat overlapping distributions in the world. Large populations may retard the growth of young trees. We strive to provide accurate information, but we are mostly just amateurs attempting to make sense of a diverse natural world. In the United States, a lady beetle called the mealybug destroyer Cryptolaemus montrouzierigreen lacewing Chrysoperla rufilabris larvae, and some other species of lady beetles have occasionally been found around the euphyllur psyllid Johnson et al.
Feeding in this manner reduces nutrients that are essential for tree development and fruit production.
Olive Psyllid – Euphyllura olivina –
Additionally, olive psyllids tend to select healthy hosts over unhealthy hosts M. These types of losses have not been reported in California.
In areas with euphylulra temperatures, psyllid numbers may be reduced by pruning out center limbs to enhance air circulation. This only becomes a problem when olive psyllids are on inflorescences flower clusterswhich ultimately affects fruit production. There are generations of olive psyllid per year and the most damaging are the first two spring generations.
Olive psyllid – Euphyllura olivina (Costa, ) (Hemiptera:Psyllidae) an occasional pest in olive
Euphyllura olivine, the olive psyllid, was discovered in July in the California counties of San Diego and Orange and positively identified in September Olvina third generation of nymphs appears in September and October Zalom et al. Large populations are able to retard the growth of young trees. They are found in the Mediterranean Basin and the Middle East.
The eggs are elliptical, euphylluda. Olive trees aren’t common on the island but are used as an ornamental tree in a few places. Bugguide is hosted by: Photograph by Marshall W.
Euphyllura olivina has three host plants that it feeds upon and lays eggs on: Nymphs and adults feed by rupturing cells and ingesting sap.
The first generation feeds as nymphs beginning in March Alford There are three generations per year. Contributors euphyklura the copyright to and are solely responsible for contributed content.

The waxy secretion completely covers the nymphs, most likely to hide them from predators or to prevent desiccation M. Click the contributor’s name for licensing and usage information. Infested trees are contaminated with masses of wax and sticky honeydew upon which sooty moulds develop produced by larvae. Olive psyllid – Euphyllura olivina Costa, Hemiptera: Ferguson, Pomology, UC Davis.
In California, psyllid populations decline after June due to the rise in temperature and populations do not recover until the euphyllurq spring Zalom et al.
