In the last few decades, new invaders have become established and spread across African landscapes, adding to the damage caused by old invaders and natives to natural . Many former eucalyptus pests in California such as the bluegum psyllid (Ctenarytaina eucalypti) and eucalyptus snout beetle (gumtree weevil, Gonipterus scutellatus), are now under complete biological control from natural enemies deliberately introduced. Do not wait until pest infestations or damage symptoms are severe to monitor trees because cultural controls such as providing sufficient soil moisture (generally by irrigation) and avoiding any nitrogen application to host tree's root zone are primarily preventive and must be practiced early.
