本文系从近20年(1963—1983)来国内外植物线虫文献资料中,收集有关植物寄生类、根际土壤伴生类线虫147属,1244种,依其危害寄主的经济价值和栽培面积、寄生植物的范围、国内外分布、生活习性、危害部位、症状、病情、产量损失、能否传播病毒,与真菌、细菌能否相互作用致病,以及传播途径及检疫国家等情况,采用四级评分标准进行综合分析。按其检疫重要性评价的累计总分,划分成六大类:一类,毁灭性外检对象6种;二类,危险性病原线虫14种,国内多无分布,可作限制进口的内控外检对象;三类,对寄主危害严重的病原线虫40种,含国内分布不广、而限制进口的内控外检及内检对象;四类,对产量品质有威胁性的病原线虫30种,国内都有分布,
Based on the literature of plant nematodes at home and abroad from the past 20 years (1963-1983), we collected 147 genera and 1244 species of plant-parasitoid and rhizosphere soil-associated nematodes. According to their economic value and cultivated area, The range of plants, the distribution at home and abroad, the habits, the parts, the symptoms, the disease, the loss of production, the ability to transmit the virus, the interaction with fungi and bacteria, the route of transmission and quarantine countries were analyzed by four grades Standard for a comprehensive analysis. According to the cumulative total score of the quarantine importance assessment, it is divided into six categories: one category and six devastating subjects; the other two category and 14 dangerous pathogenic nematodes, which are mostly non-domestic and can be used as import-restricted internal control 40 species of pathogenic nematodes that are seriously harmful to the host, including the internal control and inspection objects that are not widely distributed in China and restricted the import; 30 species of pathogenic nematodes that threaten the yield and quality of domestic products, Have a distribution,
