Abstract : the investigation and the development of plant nematodes in china was summarized , investigation indicated that the control of the plant nematodes is still a serious subject in china 文摘:简要介绍了我国植物线虫分布和防治的研究进展，指出了植物线虫的防治在我国仍然是一个重要的课题，并对发展方向提出了自己的建议。
Neuron laser tag : always looking for snappy ways to control neurons , researchers have engineered mammalian and nematode neurons to wink off at the touch of a laser beam 神经元的激光迷藏：一直以来，研究者们总是要寻找快捷的方法来控制神经元，现在他们已经完成了一项工程，可以使哺乳动物和线虫的神经元对着射来的激光束“眨眼” 。
The control effect of two biological agents for root - knot nematode were over 77 % , and these two kinds of agent could improve fruit quality and yield of 27 . 97 % ~ 38 . 14 % of cucumber 摘要利用生物农药进行防治黄瓜根结线虫试验，结果表明，两种供试生物制剂对露地黄瓜根结线虫的防效都达到了77 %以上，并可提高产量27 . 97 % ~ 38 . 14 % .此外显著提高了黄瓜果实的品质。
We propose to integrate the life strategy approach and trophic group classification to obtain a better understanding of nematode diversity and their functions , so as to use nematodes as effective bioindicators in farmland ecosystems 建议通过综合土壤线虫的生活史策略和营养类群等信息，深入了解其生物多样性和土壤生态系统功能，从而更好地发挥土壤线虫对农田生态系统变化的生物指示作用。
This paper introduces the main factors influencing soil nematode diversity in farmland ecosystems , reviews the present situation in the nematode diversity research field and presents the research prospect of nematode diversity in the future 本文介绍了农田生态系统中影响线虫多样性的主要因素；回顾了土壤线虫的物种多样性、营养类群多样性、生活史多样性和功能多样性的研究现状；并提出了今后农田生态系统线虫多样性研究的重点。
There were significant correlation between md and abundance of nematode ( p < 0 . 05 ) and weak negative correlation among water depth and numbers of meiofauna , nematode and copepods ( p > 0 . 05 ) . biomass spectra , the biomass distribution over a sequence of the body size intervals , provide dynamic information about the relationships among components in ecosystem 小型底栖动物、海洋线虫和桡足类的丰度和生物量与环境因子进行pearson相关性分析，结果显示海洋线虫的丰度与沉积物的中值粒径相关性显著( p 0 . 05 ) 。
