Status of Ditylenchus gallaeformis as a biocontrol agent for Miconia calvescens in Hawaii

Ditylenchus gallaeformis, a nematode, causes severe leaf distortion and galling on Miconia calvescens. It was sent to the Hawaii Department of Agriculture in 2006 and a colony was established. Host range testing is underway (2007). The organism caused incipient galls on Clidemia hirta (Koster's curse) but did not affect the native Metrosideros polymorpha (ohia).
