brimblecombei Moore, 1964

Type locality: Australia.

Additional distribution: Introduced in Europe, South America, and USA (Valente & Hodkinson 2009).

Host plant: Several Eucalyptus spp., including E. camaldulensis, E. globulus, E. nitens, E. blakelyi, E. brassiana, E. bridgesiana, E. camphora, E. dealbata, E. diversicolor, E. sideroxylon, E. nicholii, E. lehmannii, E. rudis, E. tereticornis, E. mannifera, E. maculosa .

Remarks: First recorded in California in June 1998 (Gill 1998). This pest is a major threat to susceptible Eucalyptus species (in particular E. camaldulensis, E. rudis, E. tereticornis which can experience heavy defoliation) that are grown in urban landscapes, as wind shelters, or as commercial forest species (Brennan et al. 1999; Brennan et al. 2001a); common name: red gum lerp psyllid.

Parasitoids and Predators: Psyllaephagus bliteus Riek (Daane et al. 2005; Dahlsten et al. 2005) released in California as a biocontrol in 2000. Laboratory studies have demonstrated that P. bliteus can lay eggs in psyllid nymphs of any age, but female parasitoids prefer third and fourth instars (UC Riverside, CISR; UC Berkeley, CBC). In some cases, generalist predators (e.g., Anthocoris nemoralis, Hemiptera: Anthocoridae) may interfere with the effectiveness of P. bliteus to control psyllid populations (Erbilgin et al. 2004). At least four coccinellid beetles ( Coleoptera) and lacewings ( Neuroptera) have been recorded feeding on this psyllid (Erbilgin et al. 2004).
