Description and Distribution of Three Criconematid Nematodes from Hangzhou, Zhejiang Province, China

Maria Munawar/ Thomas O. Powers/ Zhongling Tian/ Timothy Harris/ Rebecca Higgins/ Jingwu Zheng

Abstract Populations of Criconemoides parvus, Discocriconemella hengsungica, and Discocriconemella limitanea, isolated in Hangzhou, China from the rhizosphere soil of woody perennials were characterized morphologically and molecularly. The morphometric data of the Chinese populations were compared with populations from other regions of the world. DNA barcoding with the mitochondrial COI gene confirmed conspecificity of Chinese and Costa Rican populations of D. limitanea. Phylogenetic assessment (..)

Morphological and Molecular Characterization of Paralongidorus sali Siddiqi, Hooper, and Khan, 1963 with a Description of the First-Stage Juvenile and Male of Longidorus jonesi Siddiqi, 1962 from China

Ruihang Cai/ Munawar Maria/ Nan Qu/ Pablo Castillo/ Jingwu Zheng

Abstract Longidorids are economically important plant-parasitic nematodes because several species are virus vectors. Populations of Paralongidorus sali and Longidorus jonesi, isolated from woody perennials of Hangzhou, Zhejiang, China, were characterized molecularly and morphologically. The morphometric data of the Chinese populations of both species were compared with other populations. The present study provided a first record of the occurrence of Paralongidorus in China coupled with descripti(..)

Chemotaxis of Caenorhabditis elegans toward volatile organic compounds from Stropharia rugosoannulata induced by amino acids

Jing Bian/ Haili Zhang/ Shuai Meng/ Yajun Liu

A variety of natural substances including both volatile organic compounds and water-soluble compounds play a significant role in the chemotactic behaviors of the model nematode Caenorhabditis elegans. We observed chemotactic behaviors of C. elegans with respect to response to attractants produced by nematode parasitic fungus Stropharia rugosoannulata, which were partially induced by specific amino acids. The results of gas chromatography-mass spectrometer analysis suggested that 1-octen-3-ol was(..)

Incidence of Oscheius onirici (Nematoda: Rhabditidae), a potentially entomopathogenic nematode from the marshlands of Wisconsin, USA

Weimin Ye/ Shane Foye/ Ann E. MacGuidwin/ Shawn Steffan

In a search for an entomopathogenic nematode to control cranberry insect pests, three Oscheius populations (Rhabditidae) were recovered through the Galleria-bait method from one sample taken in a wild cranberry marsh in Jackson County, Wisconsin, USA. Morphological studies with light microscopy and scanning electron microscopy, as well as molecular analyses of the near-full-length small subunit rDNA gene, D2/D3 expansion segments of the large subunit rDNA gene, internal transcribed spacer, and m(..)

Postembryonic Ventral Nerve Cord Development and Gonad Migration in Steinernema carpocapsae

Hung Xuan Bui/ Nathan E. Schroeder

Steinernema carpocapsae is an entomopathogenic nematode widely studied for its properties as a biocontrol agent in insect pest management and as a model for understanding bacterial symbioses. Less attention has been given to the development of specific anatomical structures within S. carpocapsae. A better understanding of entomopathogenic nematode development and anatomy may lead to improved biocontrol efficacy. We recently demonstrated that the neuroanatomy of S. carpocapsae IJs differs from th(..)

Influence of Temperature on Susceptibility of CVS. Tifguard and Georgia-06G Peanut to Meloidogyne arenaria

Weimin Yuan/ C. C. Holbrook/ Y. Chu/ P. Ozias-Akins/ D. W. Dickson

Tifguard was released in 2008 as a peanut cultivar with a high level of resistance to Meloidogyne arenaria. Our objective was to determine the role of temperature on infection and development of M. arenaria in Tifguard compared to that in the nematode susceptible cultivar, Georgia-06G. Temperature affected the rate of nematode infection and development in both Tifguard and Georgia-06G (P ≤ 0.05). In Georgia-06G, egg-laying females were observed 25, 20 or 25 days after inoculation at 28°C, 31°C, (..)

Identification of HG Types of Soybean Cyst Nematode Heterodera glycines and Resistance Screening on Soybean Genotypes in Northeast China

Cui Hua/ Chunjie Li/ Yanfeng Hu/ Yanzhi Mao/ Jia You/ Mingze Wang/ Jingsheng Chen/ Zhongyan Tian/ Congli Wang

Soybean cyst nematode (SCN, Heterodera glycines Ichinohe) is a serious soybean pathogen worldwide. HG Type 0 had been a predominant SCN in Heilongjiang province, the largest soybean (Glycine max L.) producing region in China. Recently, increased virulence on resistant cultivars originally developed for resistance to HG Type 0 was observed in fields. In order to identify new cultivars resistant to local SCN populations, two soil samples were collected from two counties (Anda and Wuchang) in which(..)

List of Type Specimens Deposited Since 1998 in the United States Department of Agriculture Nematode Collection, Beltsville, Maryland

Zafar A. Handoo/ Mihail R. Kantor/ Lynn K. Carta/ David J. Chitwood

The United States Department of Agriculture Nematode Collection (USDANC) is one of the largest and most valuable in existence and includes millions of specimens housed in over 39,800 permanent slides and 9,300 vials. This collection preserves type specimens of nematodes to serve as a reference for identifications and future taxonomic revisions. Also, the collection provides useful information on nematode hosts, occurrence, and distribution. The present list includes type specimens added to the U(..)

Delatylus andersoni n. gen., n. sp. (Nematoda: Neotylenchidae) Isolated from White Pine (Pinus monticola) Lumber from USA and Intercepted in Ningbo, China

Qing Yu/ Maria Munawar/ Jianfeng Gu/ Weimin Ye

Three populations of neotylenchid nematodes were isolated in Ningbo, P. R. China, from white pine lumber (Pinus monticola) imported from the USA. The nematodes were morphologically intermediate between Hexatylus and Deladenus. The nematodes were molecularly characterized based on sequences of the rDNA small subunit 18S, large subunit 28S D2/D3, and internal transcribed spacer sequences. The phylogenetic inferences placed the nematodes with other neotylenchid nematodes, i.e., Fergusobia and Rubzo(..)
