The lobate lac scale, Paratachardina pseudolobata, was detected on Oahu in October 2012 at a botanical garden, located in the vicinity of the Hono- lulu International Airport. Early surveys done by HDOA and DLNR staff in the vicinity of detection areas and nearby forest reserves detected the scale on several species, including some native species. Given that the extent of lobate lac scale infestation was currently unknown on Oahu, a preliminary survey was carried out to update the host and habitat range of this invasive species in Oahu’s native forests. Our surveys detected P. pseudolobata on four new native and three non- native host plants. The information collected from this survey will help determine the need for appropriate management efforts to avoid severe impacts and/or the loss of native species in Hawaii native ecosystems.
