中文摘要：

柑橘黄龙病（Huanglongbing）由韧皮部杆菌属细菌（Candidatus Liberobactersp．）侵染引起，是柑橘生产上的毁灭性病害，当前正在世界柑橘产区迅速蔓延，已成为制约柑橘产业健康发展的关键因素之一。介绍了柑橘黄龙病的症状以及病原的分离培养研究进展，阐述了病原的分子检测技术，包括PCR、双重PCR、实时荧光定量PCR和LAMP快速检测技术，并对病害的防控进行展望。

英文摘要：

Citrus greening disease （Huanglongbing） caused by bacterial （Candidatus Liberobacter sp.）, is a devastating disease of citrus production, is currently spreading rapidly in citrus producing areas of the world and has become a key constraint factor of the citrus industry. This article describes the symptoms of citrus Huanglongbing disease and pathogen isolation and culture, a detailed molecular pathogen detection technology, including PCR, double-PCR, real-time PCR and LAMP rapid detection technology, and made the prospect of disease prevention and control.
