The 111076 nematode individuls were classified into 43 genera and 4 trophic groups. Among them, 32 genera of nematodes belong to beneficial un-plant parasitic (bacterivorous, fungivorous, omnivorous/predatory) nematodes and 11 genera of nematodes belong to baneful phytophagous nematodes which accounted for 1/4 of nematode collectivity, especially the nematodes in the genus of Tylenchus and Filenchus, involved 51 (91%) and 42 (75%) species of flowers, repectively.

经鉴定111076条线虫分属43个属，4个营养类群（食细菌、食真菌、杂食/捕食和植物寄生线虫），其中有益的非植物线虫属32个，有害的植物线虫属11个，占总调查属数量的1/4，相对比例较大，特别是垫刃属和丝尾垫刃属的线虫出现的频率较高，涉及花卉51种和42种，分别占调查花卉总数的91％和75％。

Some strains of the nematode-bearing bacteria were bioassayed for their parasitism. All these bacteria can totally not grow or grows badly on the media incorporating the extracts of pine trees, indicating some substances existing in the trees will harmful to the bacterial strains, which is further convinced by preliminary inoculation showing that single bacterial species will not infect Pinus thugbergii. Hence, the growth and reproduction of the nematode-carrying bacteria, which could produce toxic substances causing the death of the tree cells, is closely related to the nematodes, when they first enter to the trees. In the same time, the activity of bacteria improved the circumstances for which nematodes are living, which in turn will beneficial to the growth of nematodes. Thus, there is a complicated interaction among nematodes, bacteria, and pine trees.

对松材线虫携带的细菌的部分菌株进行了寄生性测定，表明这些细菌在添加松树提取液的细菌培养基中不能生长或基本不能生长，这说明松树体内可能存在某些不利于细菌生长的物质，同时初步的接种试验证实，单独的细菌接种不能感染健康的黑松，因此，线虫携带的致病细菌在最初进入树体时，其生长和繁殖与线虫密切相关，结合细菌产生的毒性物质可造成黑松细胞死亡的情况，说明细菌的生长与线虫有关，同时，细菌的活动改变了线虫在松树内的生长环境，使环境变得有利于线虫的生活，因此，线虫、细菌和松树三者存在着复杂的生物关系。

The result indicated the basic culture had poisonous effect to nematodes, and significant virulence to different nematodes was detected, the sequence of virulence to nematodes was Caenarhabditis sp., Heterodera glycines, Meloidogyne hapla, Ditylenchus destructor.

结果表明，该发酵液呈微碱性，不同浓度发酵液对各种线虫均有较好的防治作用，并且毒力作用具有明显差异，对4种线虫的毒力大小顺序分别为小杆线虫、大豆胞囊线虫、根结线虫和腐烂茎线虫。

Entomopathogenic nematodes：昆虫病原线虫

昆虫病原线虫(entomopathogenic nematodes)作为一种理想的生物防治因子,与化学农药相比,具有很多优点,但始终未引起人们的足够重视. 直到20世纪60年代以后,由于化学农药的广泛施用,带来了一系列的环境问题,也给人类带来了严重的危机感[1],全世界应用昆虫病原线虫防治害虫的研
