Huanglongbing and its Vectors: A Pest-specific Contingency Plan for the Citrus and Nursery and Garden Industries

This contingency plan was prepared to provide information relevant to the implementation of PLANTPLAN: Australian Emergency Plant Pest Response, (Plant Health Australia 2004a) in the event of incursions of huanglongbing, a serious disease of citrus, and its known vectors, the Asiatic citrus psyllid Diaphorina citri Kuwayama [Hemiptera: Sternorrhyncha: Psylloidea: Psyllidae] and the African citrus psyllid Trioza erytreae del Guercio (Hemiptera: Sternorrhyncha: Psylloidea: Triozidae). The plan must be revised regularly to incorporate rapidly changing knowledge about host plants, advances in detection techniques for the pathogen, the distribution of the pathogens and the vectors, surveillance methodology and improvements in control methods.
