robusta ( Crawford, 1914) View in CoL
Type locality: USA, Arizona, California, Colorado, Washington.
Additional distribution: Idaho, Montana, Oregon, South Dakota, Utah, Wyoming; Canada, British Columbia. Host plant: Ceanothus fendleri , C. cordulatus , C. velutinus , C. integerrimus . Parasitoids: Prionomitus mitratus and Psyllaephagus sp.
Type locality: Europe.
Additional distribution: Western Mediterranean, including North Africa. Introduced in USA. Host plant: Olea spp., but alternate hosts in California may include Elaeagnus angustifolia , and Phillyrea latifolia ( UC Riverside, CISR).
Remarks: This species is a pest of olive trees in its native range in the Mediterranean and North Africa, and was first recorded in California in 2007 (Gill & Watson 2007). The olive psyllid aestivates during the hottest summer months resuming feeding activity after the first autumn rains. There are usually three generations per year; the second generation, around May, is associated with the flowering shoots and flower buds and may cause many flowers to abort. Large populations may retard growth of young trees. ( Hodkinson 1986; Burckhardt 1989; Ksantini et al. 2002); common name: olive psyllid.
Parasitoids and Predators: Apocharips eleaphila (Silvestri) , probably as a hyperparasitoid, and Psyllaephagus euphyllurae (Masi) . These cynipoid and encyrtid parasitoids were recorded parasitizing olive psyllid in Europe in 1951 and 1911. Other potential predators of E. olivina are Chrysoperla rufilabris (Burmeister) (lacewing, Neuroptera ) and Cryptolaemus montrouzieri Mulsant (coccinellid beetle, Coleoptera ) ( UC Riverside, CISR).
Type locality: Mexico. Additional distribution: USA, California. Host plant: Haematoxylum campechianum ( Burckhardt & Wyniger 2007) , and Caesalpinia cacalaco in California ( Gill 1997).
Remarks: First recorded in California in 1997 ( Gill 1997).
