Can Oecophylla smaragdina be used to suppress incidence of CVPD in citrus orchards in Indonesia?

Abstract Citrus vein phloem degeneration (CVPD) is the Indonesian name for Asian form of devastating and incurable citrus disease known internationally as huánglóngbìng. It associated with a phloem-limited pathogen, ‘Candidatus Liberibacter asiaticus’ (CLas) transmitted by Asiatic psyllid (ACP), Diaphorina citri. ACP originated in South Asia but was first observed on 1900 Java to where it may have been introduced decades earlier lemon or lime seedlings brought from reduce incidence scurvy among European sailors colonial settlements. CLas appears Pasar Minggu area Jakarta 1940s southern China, after Guangzhou, directly indirectly, late 1920s–early 1930s. Minimising relies planting pathogen-free trees, removal infected unstainable use synthetic pesticides that do not prevent spread disease. Parasitoids predators are killed pesticides. Evidence China Việtnam suggests effective management be feasible if weaver ant (semut rangrang), Oecophylla smaragdina, deployed, cultivated, managed orchards.
