| Outline of Final Research Achievements |
The Asian citrus psyllid, Diaphorina citri Kuwayama, (Hemiptera: Psyllidae) was discovered in Okinawa in 1998. Control of D. citri is important because this phloem-feeding pest vectors Candidatus Liberibacter asiaticus (Ca. L. asiaticus), a phloem-residing α-proteobacterium that causes citrus greening disease or Huanglongbing. This research contributes the first steps towards evaluating entomopathogenic fungi for its potential use in an IPM program to suppress D. citri populations. Fungal pathogens that killed adult D. citri in Thailand, Vietnam, Okinawa and Amami-oshima were identified and characterized. Isaria javanica from Okinawa has a high virulence against D. citri and was effective on control of D. citri in laboratory and field applications.Endophytic characteristics of I. javanica were also studied.
