【摘要】 到目前为止,在我国松树体内已经发现有寄生线虫46个已知种和一些未定种。分属于3目9科17属。其中,滑刃目(Aphelenchida)线虫数量最多,包括滑刃科(Aphelenchidae)滑刃线虫属(Aphelenchus)、伞滑刃线虫属(Bursaphelenchus),外滑刃科(Ektaphelenchidae)外滑刃线虫属(Ektaphelenchoides)、外真滑刃线虫属(Ektaphelenchus)、隐滑刃线虫属(Crytaphelenchus),长尾科(Seinuridae)长尾线虫属(Seinura)等,总共40个已知种。垫刃目(Tylenchida)包括粒科(Anguini-dae)茎线虫属(Ditylenchus),伪垫刃科(Nothotylenchidae)柱形垫刃线虫属(Cylindrotylenchus),纽带科(Hoplolaimidae)拟盘旋线虫属(Pararotylenchus),环科(Criconematidae)小环线虫属(Cri-conemella)、鞘线虫属(Hemicycliophora)等,共6个已知种。矛线目(Dorylaimida)仅有1个未定种。根据不同目、科、属、种的线虫主要形态鉴定特征,编制了46种松树寄生线虫分类检索表,从而有利于人们方便地鉴定和区分松树寄生线虫。更多还原

【Abstract】 There are 46 known species of parasitic nematodes in pine trees in China have been recorded,which belong to 17 genera of 9 families in 3 orders.The number of species in order Aphelenchida was the largest,with a total of 40 known species,including Bursaphelenchus and Aphelenchus of Aphelenchidae;Ektaphelenchus,Cryptaphelenchus and Ektaphelenchoides of Ektaphelenchidae;Seinura of Seinuridae.Six known species belong to order Tylenchida,including Ditylenchus of Anguinidae;Cylindrotylenchus of Nothotylenchidae;Pararotylenchus of Hoplolaimidae;Hemicycliophora and Criconemella of Criconematidae.There was one unknown species in Dorylaimida.A key for 46 species of pine nematode was constructed based on the morphologic characteristics of different order,genera and species.更多还原
