Interpretive Summary: Citrus huanglongbing or HLB has destroyed over 50% of the citrus trees in Florida since its introduction about ten years ago. The disease is spread by a psyllid vector. Both the vector and the disease are spreading in several citrus growing regions of the Western hemisphere with devastating effects on citrus industries in Florida and Brazil. There has been a tremendous increase in funding from various sources to combat this disease in recent years. This review is intended to briefly summarize some of the recent efforts on population genetics, detection methods, the pathosystem and the management systems. The review is intended to provide an overview of the situation rather than provide a detailed information of various research efforts.

Technical Abstract: Citrus huanglongbing (HLB) has become a major disease and limiting factor of production in the citrus areas which have become infected. The disease was first reported in the Western Hemisphere in 2004 with devastating effects in major citrus producing areas such as Brazil and Florida. The destruction to the affected citrus industries has resulted in a tremendous increase to research support that in return has resulted in a massive amount of research information of both applied and basic research. This review is intended to provide an overview of the importance of HLB to a wider audience of plant biologists, rather than the plant pathology audience of most of the previous reviews, concentrating on population genetics, detection methods, vector and host pathogen interactions, and management practices.
