Approaches to predicting current and future distributions of Puccinia psidii in South America under climate change scenarios

Abstract

Puccinia psidii is the cause of Eucalyptus/guava/myrtle rust disease of many host species in the Myrtaceae family, including guava (Psidium spp.), eucalypt (Eucalyptus spp.), rose apple (Syzygium jambos), and ohia (Metrosideros polymorpha) (Farr and Rossman 2010). First reported in 1884 on guava in Brazil (Maclachlan 1938), the rust has since been detected in other South American countries (Argentina, Colombia, Paraguay, Uruguay and Venezuela), Central America (Costa Rica and Panama), Mexico, the Caribbean (Cuba, Dominica, Dominican Republic, Jamaica, Puerto Rico, Trinidad and Tobago, Virgin Islands), USA (Florida, California, and Hawaii), and most recently Japan and Australia (Graça et al. 2010). Of present concern is the recent introduction of the rust pathogen to Hawaii, where it infects an endemic tree species known as ohia, the dominant tree species in Hawaii's remnant native forests.
