Abstract

Lesions resembling knemidokoptic mange on the feet and tarsometatarsi of two Hawai'i' Amakihi (Hemignathus virens) were observed while the researchers were mist-netting wild passerines at Manuka Natural Area Reserve on the island of Hawai'i between 14 June 2007 and 19 June 2007. During subsequent mist-netting from September 2007 through February 2008, we found 26% (7/27) of the Hawai'i' Amakihi caught were similarly affected. Microscopic examination of skin scrapings from lesions of affected individuals revealed Knemidokoptes jamaicensis (Acari: Knemidokoptidae). This is the first report of Knemidokoptes spp. found in wild passerines in Hawai'i. No other wild passerines (n=573) have been found with knemidokoptic mange during our islandwide study of Hawai'i' Amakihi.
