Additional distribution: Introduced in New Zealand, USA.

Host plant: Eucalyptus citriodora  , E. maculata  .

Remarks: A minor  pest on lemon-scented gum ( E citriodora  ) and spotted gum ( E. maculata  ) in California, and high summer temperatures appear to limit psyllid numbers ( Paine & Dreistadt 2007). First recorded in California in 1995 ( Gill 1995); common name: lemon gum psyllid.

Ctenarytaina Ferris & Klyver 

eucalypti (Maskell, 1890) 

Type locality: Australia.

Additional distribution: Introduced in Europe, New Zealand, South America, USA. Host plant: At least nine Eucalyptus  spp. ( Burckhardt 1998), including E. pulverulenta  , E. globulus  in California. Remarks: First recorded in California in the 1990 s ( Gill 1991, 1992); common name: blue gum psyllid. This species can have four or more generations per year.

Parasitoids: Psyllaephagus pilosus Noyes  ; this introduced parasitoid is a highly effective classical biological control agent. Insecticide use for this pest was eliminated by 1994 as the parasitoids spread throughout California ( Dahlsten et al. 1998).
