High-resolution melting curve analysis: A detection assay for Ceratocystis eucalypticola and C. manginecans in infected Eucalyptus.

Eucalyptus spp. in plantations are negatively affected by canker and wilt diseases caused by several species of Ceratocystis, particularly those in the Latin American Clade (LAC). Ceratocystis eucalypticola and Ceratocystis manginecans are of particular concern where disease epidemics are reported globally, with recent outbreaks emerging in South African and Indonesian Eucalyptus plantations.

Novel mutualists of two species infesting in Indonesia.

Several species in the complex have emerged as important pests of woody plants globally, particularly in habitats where they are invasive aliens. These beetles live in obligate symbioses with fungi in the genus . In this study, we identified spp.

Euwallacea perbrevis (Coleoptera: Curculionidae: Scolytinae), a confirmed pest on Acacia crassicarpa in Riau, Indonesia, and a new fungal symbiont; Fusarium rekanum sp. nov.

Non-native Acacia plantations in Indonesia were first reported to be infested by a native ambrosia beetle species, identified as Euwallacea fornicatus in 1993. Recently the level of infestation in these plantations by ambrosia beetles has steadily increased. The recent redefinition of the taxonomic parameters of the Euwallacea fornicatus species complex has resulted in the identity of the ambrosia beetle species in these plantations becoming unclear.
