Nematode, Ditylenchus, Stem and Bulb, Meloidogyne, Root Knot
BIOLOGY AND CONTROL OF STEM AND ROOT KNOT NEMATODES r Becky B. Westerdahl1 Abstract: Plant parasitic nematodes are nonsegmented-microscopic roundworms which are frequently present in alfalfa fields. Although more than 10 different genera have been found in alfalfa fields in California, two (stem and bulb, and root knot) are most commonly associated with damage. A management plan to fit a particular growing situation should be developed using a combination of techniques including: planting site selection, certified seed, clean equipment, weed and irrigation management, resistant varieties, crop rotation, fallow, organic amendments and chemical nematicides. Ke~words nematode, Ditylenchus, stem and bulb, Meloidogyne, root knot, INTRODUCTION Plant parasitic nematodes are nonsegmented-microscopic roundworms which are frequently present in alfalfa fields. Whether or not alfalfa is to be planted in a nematode infested area, a grower should be knowledgeable about nematodes. If nematodes are present, both pre and postplant management strategies should be developed for pathogenic species. If an alfalfa field or a potential planting site is not infested, a grower should be aware of techniques available to prevent the introduction of harmful species. For growers to carry on a nematode pest management program they need to be familiar with (1) nematode biology; (2) symptoms and signs of nematode f damage; (3) how nematodes injure plants; (4) how to sample for nematodes; and (5) the principles underlying various management techniques including: planting site selection, the use of certified seed, the importance of using clean equipment and irrigation water, weed management, the use of resistant varieties, crop rotation, fallow, organic amendments, and chemical nematicides. -

M. C ram4 Abstract: We describe and illustrate anew needle nematode, Longidorus americanum n. sp., associated with patches of severely stunted and chlorotic loblolly pine, ( Pinus taeda L.) seedlings in seedbeds at the Flint River Nursery (Byromville, GA). It is characterized by having females with abody length of 5.4–9.0 mm; lip region slightly swollen, anteriorly flattened, giving the anterior end atruncate appearance; long odontostyle (124–165 µm); vulva at 44%–52% of body length; and tail conoid, bluntly rounded to almost hemispherical. Males are rare but present, and in general shorter than females. The new species is morphologically similar to L. biformis, L. paravineacola, L. saginus, and L. tarjani but differs from these species either by the body, odontostyle and total stylet length, or by head and tail shape. Sequence data from the D2–D3 region of the 28S rDNA distinguishes this new species from other Longidorus species. Phylogenetic relationships of Longidorus americanum n. sp. with other longidorids based on analysis of this DNA fragment are presented. Additional information regarding the distribution of this species within the region is required.

Tokorhabditis N. Gen
www.nature.com/scientificreports OPEN Tokorhabditis n. gen. (Rhabditida, Rhabditidae), a comparative nematode model for extremophilic living Natsumi Kanzaki1, Tatsuya Yamashita2, James Siho Lee3, Pei‑Yin Shih4,5, Erik J. Ragsdale6 & Ryoji Shinya2* Life in extreme environments is typically studied as a physiological problem, although the existence of extremophilic animals suggests that developmental and behavioral traits might also be adaptive in such environments. Here, we describe a new species of nematode, Tokorhabditis tufae, n. gen., n. sp., which was discovered from the alkaline, hypersaline, and arsenic‑rich locale of Mono Lake, California. The new species, which ofers a tractable model for studying animal‑specifc adaptations to extremophilic life, shows a combination of unusual reproductive and developmental traits. Like the recently described sister group Auanema, the species has a trioecious mating system comprising males, females, and self‑fertilizing hermaphrodites. Our description of the new genus thus reveals that the origin of this uncommon reproductive mode is even more ancient than previously assumed, and it presents a new comparator for the study of mating‑system transitions. However, unlike Auanema and almost all other known rhabditid nematodes, the new species is obligately live‑bearing, with embryos that grow in utero, suggesting maternal provisioning during development. Finally, our isolation of two additional, molecularly distinct strains of the new genus—specifcally from non‑extreme locales— establishes a comparative system for the study of extremophilic traits in this model. Extremophilic animals ofer a window into how development, sex, and behavior together enable resilience to inhospitable environments. A challenge to studying such animals has been to identify those amenable to labo- ratory investigation1,2. -

These possibilities of having the editors working alongside provide an efficient work in a shorter time. We definitely need to have these workshops periodically. The objectives of this workshop were: (i) to evaluate the work that has been done over the past three years and the maintenance of the database, (ii) to welcome the editors of terrestrial and fresh water nematodes, set clear goals, assign tasks and initiate the practical work related to new initiatives and (iii) to outline practices for outreach and scientific output for Nemys (e.g. scientific papers, presentations of the progress, plans and results at an upcoming conference). On the first day it was asked to have a rapporteur for each session in order to have it registered. The original minutes are on a separate document and were used to generate this report.
