#Pear #psyllids are important #pests in pear orchards, causing sooty mold (pear russet), defoliation, reduced fruit size, and premature fruit drop. In addition, they are transmitting the phytoplasma disease pear decline. Review of their biology, damage, vector competence and management in the Annals of the Entomological Society of America (@entsocamerica) by Stefano Civolani and others - https://doi.org/10.1093/aesa/saad025

#psyllids - insect feeds on sap and secrete a sugary 'lerp'. Noisy Miners displace smaller insect eating woodland birds such as #Pardalotes refuge habitat in prickly locally indigenous shrubs
Eg
* Acacia paradoxa Hedge Wattle (2m high – very thorny so don’t plant near paths)
* Melicytus dentatus Tree Violet (2-3m high)
* Bursaria spinosa Sweet Bursaria (4-6m high)
And, though it’s not prickly, Rock Correa provides good habitat:
* Correa glabra Rock Correa (1-2m high)
