摘要

在印度泰米尔纳德邦和喀拉拉邦部分地区发现甘蔗叶螨(Schizotetranychus andropogoni, Hirst)(蜱螨亚纲:叶螨科)的命名不一致后，我们采集了甘蔗和自发糖(Saccharum spontanum)的商业杂交品种的网螨样本。蜱虫学家将这些样本鉴定为krungthepensis Naing & Auger(蜱螨目:叶螨科)，最初于2014年在泰国被描述。为了提供区分krungthepensis和S. andropogoni的分子证据，我们对NCBI数据库中两个物种的5.8S rRNA和线粒体细胞色素氧化酶I (mtCOI)基因序列进行了分子进化遗传学分析(MEGA6)。通过分析得出的系统发育树中，虽然也有一些例外，但andropogoni和S. krungthepensis具有不同的集群，从而为S. krungthepensis与S. andropogoni明显不同的物种提供了证据。鉴于krungthepensis可能对该国的甘蔗种植构成威胁，我们概述了管理这种有害生物所需的基本行动方针，如果它的影响比它所取代的本地物种更严重的话。

Web mite Schizotetranychus krungthepensis on sugarcane in India: molecular evidence for occurrence and the way forward

Following the detection of an incongruity in the nomen-clature of sugarcane web mite Schizotetranychus andropogoni (Hirst) (Acari: Tetranychidae), we collected web mite samples from commercial hybrids of sugarcane and Saccharum spontaneum in parts of Tamil Nadu and Kerala States, India. Acarologists identified these samples as Schizotetranychus krungthepensis Naing & Auger (Acari: Tetranychidae), originally described from Thailand in 2014. To provide molecular evidence to distinguish S. krungthepensis from S. andropogoni , we subjected sequences of 5.8S rRNA and mitochondrial cytochrome oxidase I (mtCOI) genes of both species available in NCBI database to Molecular Evolutionary Genetics Analysis (MEGA6). The analysis produced phylogenetic trees with distinct clusters for S. andropogoni and S. krungthepensis , albeit with some exceptions, thus provi-ding evidence to consider S. krungthepensis a species distinctly different from S. andropogoni . In view of the possible threat of S. krungthepensis to sugarcane culti-vation in the country, we outline the basic course of action needed to manage the pest if it were to assume more serious proportions than the native species it appears to be displacing.

期刊介绍： Current Science, published every fortnight by the Association, in collaboration with the Indian Academy of Sciences, is the leading interdisciplinary science journal from India. It was started in 1932 by the then stalwarts of Indian science such as CV Raman, Birbal Sahni, Meghnad Saha, Martin Foster and S.S. Bhatnagar. In 2011, the journal completed one hundred volumes. The journal is intended as a medium for communication and discussion of important issues that concern science and scientific activities. Besides full length research articles and shorter research communications, the journal publishes review articles, scientific correspondence and commentaries, news and views, comments on recently published research papers, opinions on scientific activity, articles on universities, Indian laboratories and institutions, interviews with scientists, personal information, book reviews, etc. It is also a forum to discuss issues and problems faced by science and scientists and an effective medium of interaction among scientists in the country and abroad. Current Science is read by a large community of scientists and the circulation has been continuously going up. Current Science publishes special sections on diverse and topical themes of interest and this has served as a platform for the scientific fraternity to get their work acknowledged and highlighted. Some of the special sections that have been well received in the recent past include remote sensing, waves and symmetry, seismology in India, nanomaterials, AIDS, Alzheimer''s disease, molecular biology of ageing, cancer, cardiovascular diseases, Indian monsoon, water, transport, and mountain weather forecasting in India, to name a few. Contributions to these special issues ‘which receive widespread attention’ are from leading scientists in India and abroad.
