An Agent-Based Metapopulation Model Simulating Virus-Based Biocontrol of Heterodera Glycines

Safyre Anderson/ Chinmay Soman/ Sadia Bekal/ Leslie Domier/ Kris Lambert/ Kaustubh Bhalerao

With recently discovered soybean cyst nematode (SCN) viruses, biological control of the nematodes is a theoretical possibility. This study explores the question of what kinds of viruses would make useful biocontrol agents, taking into account evolutionary and population dynamics. An agent-based model, Soybean Cyst Nematode Simulation (SCNSim), was developed to simulate within-host virulence evolution in a virus-nematode-soybean ecosystem. SCNSim was used to predict nematode suppression under a r(..)

Revisiting the Life-Cycle of Pasteuria penetrans Infecting Meloidogyne incognita under Soil-Less Medium, and Effect of Streptomycin Sulfate on its Development

Victor Phani/ Uma Rao

Pasteuria penetrans is a Gram-positive, endospore forming soil bacterium, infecting root-knot nematodes, Meloidogyne spp. Being obligate in nature, the bacterium is not easily grown in vitro, and the in vivo culturing technique is relied on the soil-based microcosm since long. Hence, culturing of P. penetrans using CYG germination pouches as a soil-less medium for plant growth, promises to provide a contamination free environment along with ease in isolation of infected females from the plant ro(..)

Molecular Identification of Entomopathogenic Nematode Isolates from the Philippines and their Biological Control Potential Against Lepidopteran Pests of Corn

Barbara L. Caoili/ Romnick A. Latina/ Regina Faye C. Sandoval/ Joey I. Orajay

In search for local entomopathogenic nematode (EPN) species as a biological control agent of lepidopterous insect pests of corn, a survey for EPN in the major islands in the Philippines was conducted. Seven EPN populations from 279 soil samples were isolated using Ostrinia furnacalis, the key target insect pest of corn in the country, as bait. Analysis of the ITS1-5.8S-ITS2 ribosomal DNA sequence revealed the presence of Steinernema abbasi, Steinernema minutum, Steinernema tami, and Heterorhabdi(..)

Nematode Genome Announcement: A Draft Genome for Rice Root-Knot Nematode, Meloidogyne graminicola

Vishal Singh Somvanshi/ Madhura Tathode/ Rohit Nandan Shukla/ Uma Rao

The rice root-knot nematode Meloidogyne graminicola has emerged as a devastating pest of rice in South-East Asian countries. Here we present a draft genome sequence for M. graminicola, assembled using data from short and long insert libraries sequenced on Illumina GAIIx sequencing platform.

Morphological Re-Description and 18 S rDNA Sequence Confirmation of the Pinworm Aspiculuris tetraptera (Nematoda, Heteroxynematidae) Infecting the Laboratory Mice Mus musculus

Rewaida Abdel-Gaber/ Fathy Abdel-Ghaffar/ Saleh Al Quraishy/ Kareem Morsy/ Rehab Saleh/ Heinz Mehlhorn

Aspiculuris tetraptera is a heteroxynematid nematoda infecting most of the laboratory animals, occasionally mice which represent the mostly used animal for biological, medical, and pharmacological studies. The present study aimed to investigate the prevalence of nematode parasites infection in the laboratory mice Mus musculus in Egypt. Morphologically, this oxyurid possessed four distinct cephalic papillae on a cephalic plate, with three small rudimental lips carrying two sessile poorly develope(..)

Stauratostoma shelleyi n. gen., n. sp. (Nematoda: Rhabditida: Thelastomatidae) from Appalachian Polydesmid Millipedes (Polydesmida: Xystodesmidae)

Gary Phillips/ Robert J. Pivar/ Xiocaun Sun/ John K. Moulton/ Ernest C. Bernard

Stauratostoma shelleyi n. gen., n. sp. is described from the midgut and hindgut of nine species of the millipede family Xystodesmidae collected in the southern Appalachian regions of North Carolina, Tennessee and Alabama. Specimens of S. shelleyi were morphologically examined with differential interference contrast, phase contrast, and scanning electron microscopy. The head of S. shelleyi differs from other thelastomatid nematodes in having a head region mushroom-shaped in profile; cruciform sto(..)

Activity of Vetiver Extracts and Essential Oil against Meloidogyne incognita

Kansiree Jindapunnapat/ Nathan D. Reetz/ Margaret H. MacDonald/ Ganga Bhagavathy/ Buncha Chinnasri/ Noppamas Soonthornchareonnon/ Anongnuch Sasnarukkit/ Kamlesh R. Chauhan/ David J. Chitwood/ Susan L.F. Meyer

Vetiver, a nonhost grass for certain nematodes, was studied for the production of compounds active against the southern root-knot nematode, Meloidogyne incognita. In laboratory assays studying the effects on second-stage juvenile (J2) activity and viability, crude vetiver root and shoot extracts were nematotoxic, resulting in 40% to 70% J2 mortality, and were also repellent to J2. Vetiver oil did not exhibit activity against J2 in these assays. Gas chromatography-mass spectrometry analyses of th(..)

Molecular Characterization and Phylogeny of Ditylenchus weischeri from Cirsium arvense in the Prairie Provinces of Canada

Mehrdad Madani/ Mario Tenuta

Ditylenchus weischeri that parasitizes the weed Cirsium arvense (L.) Scop., 1772, (creeping thistle) was described in 2011 from Russia based on their morphology, ITS-RFLP analysis, and Hsp90 gene sequence of a few individuals and one field collection of the plant. More recently, we found C. arvense parasitized by D. weischeri in the Prairie Provinces of Canada. Plant host preference for D. weischeri was also distinct from D. dipsaci (Kühn) Filipjev, 1936. In the current study, a comprehensive mo(..)

Description of Longidorus azarbaijanensis n. sp. (Dorylaimida: Longidoridae) from Iran

Farshad Gharibzadeh/ Ebrahim Pourjam/ Majid Pedram

Longidorus azarbaijanensis n. sp. is described and illustrated using morphological and molecular data. It was recovered in West Azarbaijan province, northwestern Iran, from the rhizospheric soil of foxtail weed. The new species is characterized by having 5.4 to 6.8 mm long females, offset, anteriorly flat lip region and separated from the rest of the body by a shallow constriction, funnel-shaped amphidial pouches, the guiding ring at 23 to 27 µm from the anterior end, 73 to 81 and 44 to 50 µm lo(..)

Nothotylenchus andrassy n. sp. is described and illustrated from moss (Sphagnum sp.) based on morphology and molecular analyses. Morphologically, this new species is characterized by a medium body size, six incisures in the lateral fields, and a delicate stylet (8–9 µm long) with clearly defined knobs. Pharynx with fusiform, valveless, non-muscular and sometimes indistinct median bulb.

First Report of Carrot Cyst Nematode Heterodera carotae in Mexico: Morphological, Molecular Characterization, and Host Range Study

Ilia Mariana Escobar-Avila/ Edgar Óliver López-Villegas/ Sergei A. Subbotin/ Alejandro Tovar-Soto

During 2008 to 2016 in several nematological surveys in the Tepeaca Valley, Puebla, Mexico, carrot cyst nematode, Heterodera carotae was found parasitizing carrots, Daucus carota. The nematode was present in 61% of the sampled fields with high population densities, causing severe carrot yield losses in the Tepeaca Valley. The aim of this work was to study morphology, morphometrics, host range, and molecular characterization of the nematode. The morphological and morphometric characterization was(..)
