Status of Coccodiella miconiae as a biocontrol agent for Miconia calvescens in Hawaii

The fungal pathogen Coccodiella miconiae, a potential biological control agent for Miconia calvescens (miconia), was established on miconia in the Hawaii Department of Agriculture quarantine greenhouse in 2007. This obligate parasite was hand-carried from Costa Rica in 2006 after numerous failed attempts to culture the fungus in Hawaii. It causes pimpling of miconia leaves, significantly reducing the foliar photosynthetic process. This fungus is effective in drier climates and may be a good biocontrol agent in areas where other control agents would not be effective, but it has been difficult to transfer from plant to plant. Research into the susceptibility of the miconia biotype in Hawaii, the conditions for infection and disease development, and the life cycle of the fungus are underway in Brazil (2002). In Brazil, five hyperparasitic fungi have been collected from the pimples.
