It shows that the termination of belowground photosynthate-C allocation achieved by tree girdling can affect soil nematodes.

环割对各土层中的食细菌线虫、植食性线虫和杂食与捕食性线虫密度无显著影响，这说明不同营养类群对环割的响应存在差异。

结果表明，北京密云的豇豆、番茄、苦瓜，北京植保站月季，山东胶州，烟台和潍坊的花生，安徽和县的番茄，宿州的黄瓜和太和的桔梗，北京畜牧所沙打旺以及中国农业大学两个番茄品种(RKN-23和RKN-25)上的根结线虫种群的PCR扩增片段长度为768bp；江苏赣榆苦瓜，云南昆明，河北廊坊，安徽宿州和四川成都番茄以及安徽泅县黄瓜上根结线虫种群的PCR扩增片段长度为769bp；海南安定木瓜和石榴上根结线虫种群的PCR扩增长片段度为772bp；中国农业大学另外两个番茄(RKN22和RKN-24)品种上的根结线虫种群的PCR扩增片段长度为766bp；而浙江杭州黄瓜和海南安定胡椒上的根结线虫种群的PCR扩增长度分别为767bp和869bp。

The results showed that the quantities of plant parasitic nematodes of Aphelenchoides and Aphelenchus increased at a speed of geometric order after one growing season,which indicated that the two kinds of nematodes had highly potential risk.

研究结果表明栽培前种球内的优势植物线虫——拟滑刃属和滑刃属线虫数量在百合一个生长周期结束后均以几何级数的速率增长；栽培前检出数量极少的垫刃属线虫，生长周期结束后却大量出现；栽培前少量检出的短体属、矮化属、根结属、丝尾垫刃属和伪垫刃属的线虫，周期结束后，均未再检测到。

ELISA method was used for comparison. Results The positive rate of DIGFA in testing the serum from 50 infected rats was 96.0%(48/50). The negative rate of DIGFA in healthy rats was 100%(50/50). Cross reaction with Enteroclysis (13 samples) and Tapeworm (11 sqamples) was not observed. The cross reaction rate in 18 Strongyloidiasis rats was 5.6%. The sensitivity and specificity of DIGFA is comparable with ELISA (96.7%).

结果 用DIGFA检测广州管圆线虫实验感染鼠血清50份，其阳性检出率为96.0%，50份正常鼠血清的阴性符合率达100%，DIGFA分别检测蛲虫阳性鼠血清13份，绦虫阳性鼠血清11份和粪类圆线虫阳性鼠血清18份，前二者均为阴性，后者交叉反应率为5.6%；DIGFA与ELISA平行检测30份广州管圆线虫阳性鼠血清，两法符合率达96.7%。

Nematode density, generic richness, diversity, and relative abundance of bacterivores and fungivores were higher at each stage of GT transect (from grassland to tea plantation) than at the equivalent stage of ST transect (from shrubland to tea plantation), whereas lower values of Maturity index and Nematode Channel Ratio occurred at each stage of GT transect relative to ST transect.

研究发现，GT系列各植物群落类型中的土壤线虫密度、属数、多样性、食细菌和食真菌线虫相对多度都高于ST系列中的相应植物群落类型，而土壤线虫总成熟指数和线虫通路比值均低于ST系列中的相应植物群落类型。

Under the support of the National, Guangdong and Guangzhou industrial incubation project, we have set up the biggest manufacture system and technology in China, which are even seldom seen in the world. We own: 2000L liquid fermentation industry system; 3 national invention patents including its manucfature and transport tenology Two types of entomathogenic nematode have got the import permission from the Agriculture Department of United States. Advanced methods of culture media and liquid cultivation conduce to the three times of production compared with other nematode commercial companies in the oversea, as well as the high quality control and transport technology are contributed to the firm fundamention of commercialization.

在国家，广东省与广州市等一系列产业化孵化项目的资助下，我们现已建立了年产50万亿线虫（可用于100万亩苹果小食心虫的防治），目前国内规模最大，国际上为数不多的生产系统和生产技术；拥有： 2000L 液体发酵生产系统；昆虫病原线虫产业化生产和储运技术等自主知识产权（3项国家发明专利）；两个线虫产品已获美国农业部核准的&准入&许可优化的培养基配方和液体培养方案，可获得比国外线虫商业公司专利培养基高出三倍的线虫产量，以及完善的产业化质量控制技术和贮运技术，这些均为这类生物杀虫剂的产业化奠定了坚实基础。

The contents of valine and leucine of the nematode are obvious higher than that of others in different kinds of amino acid of the nematode. The analysis of irritant factors playing a important role on the production of predacious organs showed that live nematode larva or its lytic solution can cause the production of predacious organs of the strain A1, but the latter produced less than the former .The live larva of the third stage produced more predacious organs than one of the first and the second stage , so the number of predacious organs that are produced by the live larva of first and the second the stage are less than the live larva of the third stage .

刺激捕食器产生的因素在线虫体来说：活的线虫幼虫和其裂解液可以刺激捕食线虫性真菌—少孢节丛孢菌菌株产生捕食线虫性结构——捕食器；但后者刺激产生的捕食器数量较少；有活力的第三期幼虫与第一、二期幼虫相比较，可以刺激菌株产生较多的捕食器；但少孢节丛孢菌对第一、二期幼虫作用速度快；与第三期幼虫相比，第一、二期幼虫易被捕获致死。

The assay of the coarse protein , a variety of amino acid about nematode-trapping fungus — Arthrobotrys oligospora strain A1 and the third stage larva showed that the contents of the coarse protein and a variety of amino acid of larva are mostly higher than that of predacious organs containing annulus and cohesive net ,conidia and hypha in the different growth phases.

捕食线虫性真菌——少孢节丛孢菌菌株及线虫第三期幼虫的粗蛋白质和各种氨基酸种类及其含量化学成份测定结果表明：捕食线虫性真菌—少孢节丛孢菌的各生长阶段和线虫幼虫的粗蛋白质和氨基酸的种类和含量比较显示：线虫幼虫的粗蛋白质和各种氨基酸的含量大多数都高于少孢节丛孢菌捕食器、分生孢子、和菌丝的含量；结果还说明：捕食器菌丝的化学组成也与普通菌丝不一样。

Elegans were significantly decreased after exposure to ENIs（p.05）; also the brood size and the lifespan of C. elegans were significantly reduced after exposure to ENIs（p.05）. Moreover, after exposure to ENIs, the lifespan of mev-1 mutant hermaphrodites was shorter than that of wild type（p.05）, indicating that mev-1 gene mutant could result in more sensitivity of the mutant hermaphrodites to ENIs exposure than the wild type.

结果表明：空气负离子暴露可显著加速野生型和mev-1突变型线虫发育（p.05），缩短寿命（p.05），与野生型相比，空气负离子暴露对mev-1突变线虫寿命影响更大（p.05）；空气负离子暴露可显著降低线虫后代数量（p.05），原因可能在于空气负离子暴露显著诱导性腺细胞凋亡的增加（p.05）。
