  • 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.

  • Dolichodorus Heterocephalus Cobb, 1914
    CA LIF ORNIA D EPA RTM EN T OF FOOD & AGRICULTURE California Pest Rating Proposal for Dolichodorus heterocephalus Cobb, 1914 Cobb’s awl nematode Current Pest Rating: A Proposed Pest Rating: A Domain: Eukaryota, Kingdom: Metazoa, Phylum: Nematoda, Class: Secernentea Order: Tylenchida, Suborder: Tylenchina, Family: Dolichodoridae Comment Period: 08/10/2021 through 09/24/2021 Initiating Event: This nematode has not been through the pest rating process. The risk to California from Dolichodorus heterocephalus is described herein and a permanent pest rating is proposed. History & Status: Background: The genus Dolichodorus was created by Cobb (1914) when he named D. heterocephalus collected from fresh water at Silver Springs, Florida and Douglas Lake, Michigan. This nematode is a migratory ectoparasite that feeds only from the outside on the cells, on the root surfaces, and mainly at root tip. They live freely in the soil and feed on plants without becoming attached or entering inside the roots. Males and females are both present. This genus is notable in that its members are relatively large for plant parasites and have long stylets. Usually, awl nematodes are found in moist to wet soil, low areas of fields, and near irrigation ditches and other bodies of fresh water. Because they prefer moist to wet soils, they rarely occur in agricultural fields and are not as well studied as other plant-parasitic nematodes (Crow and Brammer, 2003). Infestations in Florida may be due to soil containing nematodes being spread from riverbanks CA LIF ORNIA D EPA RTM EN T OF FOOD & AGRICULTURE onto fields, or by moving with water during flooding (Christie, 1959).

BMC Ecol (2017) 17:41 https://doi.org/10.1186/s12898-017-0153-9 BMC Ecology RESEARCH ARTICLE Open Access Diversity of root‑knot nematodes in Moroccan olive nurseries and orchards: does Meloidogyne javanica disperse according to invasion processes? Mohamed Aït Hamza1,2* , Nadine Ali2,3, Johannes Tavoillot2, Odile Fossati‑Gaschignard2, Hassan Boubaker4, Abdelhamid El Mousadik1† and Thierry Mateille2† Abstract Background: Root-knot nematodes (RKN) are major pest of olive tree (Olea europaea ssp. europaea), especially in nurseries and high-density orchards. Soil samples were collected from main olive growing areas of Morocco, to char‑ acterize Meloidogyne species and to discuss the contribution of biotic and abiotic factors in their spatial distribution. Results: RKN were found in 159 soil samples out of 305 from nurseries (52.1% occurrence) and in 11 out of 49 soil samples from orchards (23.2% occurrence). Biochemical and molecular characterisation (PAGE esterase and SCAR) revealed the dominance of M. javanica both in nurseries and orchards with minor presence of M. incognita only in nurseries, and M. arenaria in only one nursery. RKN were distributed on aggregated basis. Frequent presence of M. javanica in orchards might have come from nurseries. In contrast, the detection of M. incognita in nurseries alone sug‑ gests that this species could not reproduce in orchards because of either the competition with other plant-parasitic nematodes or unft local habitats. The impact of environmental variables (climate, habitat origin and physicochemical characteristics of the substrates) on the distribution of Meloidogyne species is also discussed. Conclusion: Olive nurseries in Morocco are not able to guarantee the safety of rooted plants.

Acceplecl for publication 5 November 1996. Summary - In Argentina, soil nematodes constitute a diverse group of invertebrates. This widely distributed group incJudes more than twO hundred currently valid species, among which the plant-parasitic and entomopathogenic nematodes are the most remarkable. The former includes species that cause damages to certain crops (mainly MeloicU:igyne spp, Nacobbus aberrans, Ditylenchus dipsaci, Tylenchulus semipenetrans, and Xiphinema index), the latter inc1udes various species of the Mermithidae family, and also the genera Steinernema and Helerorhabditis. There are few full-time nematologists in the country, and they work on taxonomy, distribution, host-parasite relationships, control, and different aspects of the biology of the major species. Due tO the importance of these organisms and the scarcity of information existing in Argentina about them, nematology can be considered a promising field for basic and applied research. Résumé - Les nématodes et l'agriculture en Argentine. Un aperçu général - Les nématodes du sol représentent en Argentine un groupe très diversifiè. Ayant une vaste répartition géographique, il comprend actuellement plus de deux cents espèces, celles parasitant les plantes et les insectes étant considèrées comme les plus importantes. Les espèces du genre Me/oi­ dogyne, ainsi que Nacobbus aberrans, Dùylenchus dipsaci, Tylenchulus semipenetrans et Xiphinema index représentent un réel danger pour certaines cultures.

  • Biodiversity of Compost Mesofauna and Its Potential As an Indicator of the Composting Process Status
    ® Dynamic Soil, Dynamic Plant ©2011 Global Science Books Biodiversity of Compost Mesofauna and its Potential as an Indicator of the Composting Process Status Hanne Steel* • Wim Bert Nematology Unit, Department of Biology, Ghent University, K.L. Ledeganckstraat 35, 9000 Ghent, Belgium Corresponding author : * [email protected] ABSTRACT One of the key issues in compost research is to assess the quality and maturity of the compost. Biological parameters, especially based on mesofauna, have multiple advantages for monitoring a given system. The mesofauna of compost includes Isopoda, Myriapoda, Acari, Collembola, Oligochaeta, Tardigrada, Hexapoda, and Nematoda. This wide spectrum of organisms forms a complex and rapidly changing community. Up to the present, none of the dynamics, in relation to the composting process, of these taxa have been thoroughly investigated. However, from the mesofauna, only nematodes possess the necessary attributes to be potentially useful ecological indicators in compost. They occur in any compost pile that is investigated and in virtually all stages of the compost process. Compost nematodes can be placed into at least three functional or trophic groups. They occupy key positions in the compost food web and have a rapid respond to changes in the microbial activity that is translated in the proportion of functional (feeding) groups within a nematode community. Further- more, there is a clear relationship between structure and function: the feeding behavior is easily deduced from the structure of the mouth cavity and pharynx. Thus, evaluation and interpretation of the abundance and function of nematode faunal assemblages or community structures offers an in situ assessment of the compost process.
