Study confirms A. yasumatsui as sole biotic threat to Micronesian cycad

A new study has confirmed that the invasive A. yasumatsui, known as Cycad Aulacaspis Scale (CAS), stands alone as the greatest threat to the existence of the Cycas micronesica species. The endemic cycad species to Micronesia has thrived in the region for 9,000 years but is now threatened with extinction following the arrival of the invasive scale in Guam discovered in 2003.
