摘要
针属线虫是一类营外寄生的植物线虫 ,对植物的危害比较隐蔽。从 2 773份植物根际土的线虫标本中获得针属线虫标样 2 72份 ,观察鉴定到针属线虫 1 2个种。结果表明 :针属线虫在我国的寄主范围较广泛 ,寄主植物有 2 5 0多种。该线虫不但在大豆、玉米等各种作物根围发现 ,而且在树木、杂草、蔬菜、花卉等植物根围也广泛存在。针属线虫主要分布在我国的 1 1个省、自治区的 44个市县 ,以北方地区为主 ,在南方地区发现较少。针属线虫中以突出针线虫的出现频率最高 ,发现数量最多 ,可寄生 3 9科 1 0 0个属的 1 1 4种植物 ;其次是新突出针线虫、李子针线虫、双花针线虫和新钝头针线虫等的出现频率较高。
More than 272 samples of pin nematodes were identified from 2773 nematode samples. About 12 species of Paratylenchus were systematically observed and identified by microscope. The result showed that Paratylenchus had wide host plants more than 250 species, not only around the rhizosphere of crop such as maize and soybean, but also on the root soil of tree, weed, vegetable, flowers, and so on. Paratylenchus were distributed in 44 cities and counties of 11 provinces and autonomous regions in China. Most of them were distributed in northern region, while they were found fewer in southern region. P. projectus was always found around roots of hosts about 114 species,100 genera,39 families plants. The other pin nematodes such as P. dianthus, P. neoamblycephalus ,P. prunii and P.neoprojectus were observed frequently in China.
