水稻（Oryza sativa）是世界上大多数人口的重要粮食作物，特别是在亚洲。然而，在制约作物成功生产的各种病虫害中，植物寄生线虫发挥着重要作用，造成的产量损失高达90%。与水稻相关的主要线虫害虫有古斯特双翅虫、贝塞阿菲氏线虫、赫斯曼氏菌、稻谷异线虫和禾谷细线虫。然而，水稻根结线虫（M. graminicola）恰好是最重要的害虫，在世界主要水稻生产国普遍存在。在印度，全印度协调研究项目（线虫）编制的线虫分布地图集记录了不同邦水稻种植区的M. graminicola分布情况，该地图集于2010年由印度新德里农业研究委员会农业信息和出版局出版。受稻瘟病影响的水稻植株表现为发育迟缓和黄化，这是由于根系上特征性的末端肿胀/瘿瘤，最终导致生长和产量严重下降。许多针对稻瘟病菌的生态友好型管理技术已经被开发和展示，包括使用生物制剂将水稻根结线虫造成的损失降至最低。本文主要对水稻根结线虫的生态需求、危害症状、生物学、形态、寄主范围和管理策略等方面的信息进行整理，以了解水稻根结线虫的现状。
Rice (Oryza sativa) is an important staple food crop for majority of human population in the world in general and in Asia in particular. However, among various pests and diseases which constitute important constraints in the successful crop production, plant parasitic nematodes play an important role and account for yield losses to the extent of 90%. The major nematode pests associated with rice are Ditylenchus angustus, Aphelenchoides besseyi, Hirschmanniella spp., Heterodera oryzicola and Meloidogyne graminicola. However, rice root-knot nematode (M. graminicola) happens to be the most important pest and is prevalent in major rice producing countries of the world. In India, the distribution of M. graminicola in rice growing areas of different states has been documented in nematode distribution atlas prepared by All India Coordinated Research Project (Nematodes) and published by Directorate of Information and Publications of Agriculture, Indian Council of Agricultural Research, New Delhi, India during 2010. M. graminicola affected rice plants show stunting and chlorosis due to the characteristic terminal swellings/galls on the roots which ultimately result in severe reduction in growth and yield. Number of eco-friendly management technologies against M. graminicola have been developed and demonstrated, including the use of bioagents for minimising the losses due to rice root-knot nematode. This review is focused on collating information to understand the current scenario of rice root-knot nematodes with greater emphasis on its ecological requirements, damage symptoms, biology, morphology, host range and management strategies.
