| Popis: | The blue gum psyllid was first discovered in North America in Monterey County in January 1991. Since then it has quickly spread throughout the California coastal area and has became a major pest on Eucalyptus palverulenta in commercial foliage plantations. Large amounts of pesticides have been used to control the psyllid in these plantations. A primary parasitoid wasp, Psyllaephagus pilosus Noyes (Hymenoptera: Encyrtidae), was found in Australia and New Zealand and released at eight sites in California in spring/summer 1993. As a result, psyllid populations declined somewhat at most sites in 1993, and in 1994 psyllids were no longer a problem. The parasitoid has spread rapidly to other coastal areas. |
