前言 柑桔黄龙病是华南地区柑桔生产的严重病害。为了探讨其病原及传病途径,骆学海(1977)、广西柑桔黄龙病研究小组(1977)和赵学源(1979)等进行了木虱传病试验,并提出木虱是柑桔黄龙病的传毒昆虫;柑桔黄龙病的发生与流行,和柑桔木虱分布有关。1978年我们在病叶叶脉的韧皮组织发现病原体后,在广东博罗杨村华侨柑桔场对木虱田间发生规律及生活史进行观察,同时开展柑桔木虱传毒试验,对传毒昆虫唾液腺及传毒后的发病苗进行包埋超薄切片、电子显微镜观察。
Preface Citrus Huanglongbing is a serious disease of citrus production in southern China. In order to explore its pathogen and pathogenicity, Lu Xuehai (1977), Guangxi Citrus Huanglongbing Research Group (1977) and Zhao Xueyuan (1979) conducted a test of Psyllabic disease and proposed that Psylla is the transmission of citrus Huanglongbing Insects; the occurrence and prevalence of citrus yellow dragon’s disease, and the distribution of citrus psylla. In 1978, we found pathogens in the phloem of diseased leaf veins and observed the occurrence and life history of the planthopper in the overseas citrus fruit field of Boluo Yangcun in Guangdong Province. In the meantime, Insect salivary glands and virus-infected seedlings were embedded in ultra-thin sections, electron microscopy.
