摘要
1985—1988年在全省采集到植物根结线虫病标本154份。通过形态学鉴定结果:河南省植物根结线虫共有13种,其中寄生在中华猕猴桃(Actinidia Chi-nensis)上的根结线虫为一新种—猕猴桃根结线虫(Meloidogynr actinidia Lisp.nov.),南方根结线虫(M.incognita)为优势种,约占80%;勒克瑙根结线虫(M.incknowica)等6个种为全国新纪录种;济南根结线虫(M.Jinane-nsis)为河南省首次报道。根结线虫的寄主植物约92种,分属于38科85属,其中怀牛膝(Achyranthes bidentata)等8种寄主植物为国内首次报道,粟(set-afia italica)等15种寄主植物为河南省新纪录。同时对河南省植物根结线虫的分布、寄主范围等作了调查和研究。
154 specimens of plant root-knot nematodes were collected in He-nan Province.Morphology identification demonstrated that plant root-knotnematodes in Henan have 13 species,among wohich one is new Species—M-eloidogyne actinidia Li Sp.nov.,6 species containing M.Lucknowica etc.arefirst reported in China and M.Jinanensis is new record in Henan.Host pl-ants contain 92 Species belonging to 38 families,85 generas.The 8 specieswhich contain Achyranthes bidentata Blum etc.are first reported in China.The 15 species which contain setaria italica Benav etc.are new record inHenan.Relationship between development of root-knot nematodes and ecol-ogy enrironment was also analysed.
