油橄榄根结线虫病在广西、广东、江西和福建等省均有发生。1979年在广西桂林、柳州对此病做了调查,油橄榄感染此病后根部出现虫瘿和肿瘤(根结),须根多而乱,后期根部表皮破裂影响植株对水份和养份的吸收,致使叶片提早脱落,出现枯枝,产量降低。经鉴定油榄橄根结线虫病病原线虫属于垫刃目Tylenchida Thorne,1949.垫刃亚目 Tylenchina(Orley,1880) Geraert 1966.异皮总科 Heteroderoidea(Filipjev,1934) Skarbilovich,1959.异皮科 Heteroderidae(Filipjev,1934) Skarbilovich,1947.根结线虫亚科 Meloidogyninae Skarbilovich,1959.根结线虫属 Meloidogyne Goeldi,1887.
Oleagra root knot nematode disease in Guangxi, Guangdong, Jiangxi and Fujian provinces have occurred. In 1979, Guilin, Guangxi, Liuzhou, a survey of the disease, Olive infected with the disease after the emergence of nematodes and tumors (root knot), fibrous roots and more chaos, the late rupture of the root epidermis affect plant water and nutrient absorption, As a result, the leaves fall off earlier and the dead branches appear and the yield decreases. Identification of olive root knot nematode pathogen Nematode Belong to Tylenchida Thorne, 1949. Genus Tylenchina (Orley, 1880) Geraert 1966. Heteroderoidea heterostosis (Filipjev, 1934) Skarbilovich, 1959. Heteroplasma Heteroderidae (Filipjev, 1934) Skarbilovich, 1947. Root-knot nematode Meloidogyninae Skarbilovich, 1959. Meloidogyne Goeldi, 1887.
