First report of Seville root-knot nematode, Meloidogyne hispanica (Nematoda: Meloidogynidae) in the USA and North America

, bean, and others in several countries of Europe, Asia, Africa, Central and South America (Maleita et al., 2012a, 2012b; Subbotin et al., 2021). Until now, there have been no verified reports of this nematode in North America. Meloidogyne hispanica belongs to the Ethiopica group of root-knot nematodes, which also contains the species M. ethiopica, M. luci and M. inornata (Alvarez-Ortega et al., 2019). The objective of this work was to provide morphological and molecular characterization of this root

This article presents the different intermodal transport systems in selected countries in the world, with an indication of their development and impact on environmental protection. The conducted research indicates much faster development of intermodal transport as compared to the transport of goods in other technologies. The studies were based on the latest obtainable statistics on intermodal transport from Asia, Europe, North America, and Australia. In all the cases examined, it is apparent

Pratylenchus smoliki, a new nematode species (Pratylenchidae: Tylenchomorpha) from the Great Plains region of North America

Globally, there are 103 described species of Pratylenchus according to a recent accounting (Nguyen et al., 2019). A regional survey of the Central Great Plains of North America, conducted using a DNA barcoding approach, recorded nine described species and a roughly equivalent number of potentially undescribed species (Ozbayrak et al., 2019). One of those undescribed species, previously referred to as Pratylenchus sp. 1 in Ozbayrak et al. (2019) was described as Pratylenchus dakotaensis (Handoo

A COI DNA barcoding survey of Pratylenchus species in the Great Plains Region of North America

Global estimates indicate that there are approximately 100 described species in the genus Pratylenchus Filipjev, 1936 (Janssen et al., 2017; Singh et al., 2018). In total, 27 of these species have been reported from North America by Castillo and Vovlas (2007). This number has increased to 29 with the descriptions of P. floridensis De Luca, Troccoli, Duncan, Subbotin, Waeyenberge, Moens & Inserra, 2010 and P. parafloridensis De Luca, Troccoli, Duncan, Subbotin, Waeyenberge, Moens & Inserra, 2010

Molecular and morphological characterization of the alfalfa cyst nematode, Heterodera medicaginis, from Utah

report of the alfalfa cyst nematode in North America was reported in Kansas by Powers et al. (2019). Previously, unpublished records of this cyst species reproducing on alfalfa indicated the presence of this nematode in the Great Plains states of Kansas and Montana (Powers et al., 2019). The soil sample was collected from Delta, Utah (Millard county) and sent to University of Idaho for initial evaluation, after which it was submitted to USDA-ARS in Beltsville, MD for morphological and molecular

Prevalence of the root lesion nematode virus (RLNV1) in populations of Pratylenchus penetrans from North America

samples from the Pacific Northwest of North America by nematode diagnostic laboratories labs from 2012 to 2016 (Zasada et al., 2019). The objectives of this study were: to determine the distribution of the RLNV1 in geographically distinct P. penetrans populations obtained from different North American cropping systems and to assess genetic variability of the virus by comparing sequence variations of the helicase and RNA-dependent RNA polymerase (RdRP) regions of identified RLNV1 isolates from the P

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

Differential diagnosis: Males were not described in the original description by Raski (1952). The type locality was near Winnemucca, Nevada in the mountains of western North America around the roots of Artemisia sp. Subsequent reports mention females with spermatheca filled with sperm but it was not until 34 years later that Rashid et al., (1986

Genetic variation within a species of parasitic nematode, Skrjabingylus chitwoodorum, in skunks

one genus or species (Tumlison and Tumlison, 2019). Increased sampling across the United States might have provided a better understanding of geographic variation in S. chitwoodorum. Additionally, acquiring more samples from the same regions (counties) would have allowed us to perform population-level genetic analyses. Similarly, only one sample from host genus Spilogale was present in our study. More samples from the distributional range of this genus in North America are needed to assess

Species Delimitation and Description of Mesocriconema nebraskense n. sp.(Nematoda: Criconematidae), a Morphologically Cryptic, Parthenogenetic Species from North American Grasslands

Nematode surveys of North American grasslands conducted from 2010 to 2015 frequently recovered a species of criconematid nematode morphologically resembling Mesocriconema curvatum. These specimens were recovered from remnant native prairies in the central tallgrass ecoregion of North America, and not from surrounding agroecosystems. Historical records indicate that M. curvatum is a cosmopolitan species feeding on a wide range of agronomic and native plants. DNA barcoding

Prevalence and characteristics of three subtypes of dating violence among Danish seventh-grade students

Background:A high prevalence of adolescent dating violence (ADV) has been documented in recent years. However, the majority of ADV studies have been conducted in North America and moreover, ADV studies have primarily focused on high school or college populations.Objective:To investigate victimization and perpetration of ADV and related gender differences in a sample of Danish seventh-grade students.Method:In total, 2934 seventh-grade students (M = 3.5, SD = 0.5) filled out questionnaires at

Nitrogen inputs and irrigation frequency influence population dynamics of Mesocriconema xenoplax under grapevines

The ring nematode, Mesocriconema xenoplax, is an economically important parasite of woody perennial fruit crops including Vitis spp. wine-grape (Pinkerton et al., 2004) and Prunus spp., such as peach and plum (Ferris et al., 2004; Cao et al., 2006). Most wine-grape and tree-fruit production in western North America occurs in semi-arid regions with nutrient-poor soils and is dependent on irrigation and supplemental nitrogen (N) inputs for optimal productivity. For reasons of optimizing fruit

Materials and methods Two soil samples and grapevine roots were sent to the Mycology and Nematology Genetic Diversity and Biology Laboratory, Beltsville, MD in 2019. The origin of the soil samples was a vineyard from Mosca, Alamosa County, Co. Nematodes were extracted from soil using sugar centrifugal flotation and Baermann funnel methods. Nematodes were fixed in 3% formaldehyde

northwestern North America were discovered. Nematodes were identified and characterized microscopically and molecularly with 28S ribosomal RNA (rRNA) and 18S rRNA molecular markers. From P. angustifolia, Aphelenchoides saprophilus was inferred to be closest to another population of A. saprophilus among sequenced taxa in the 18S tree. From P. trichocarpa, Laimaphelenchus heidelbergi had a 28S sequence only 1 bp different from that of a Portuguese population, and 1 bp different from the

Curative Control of the Peachtree Borer Using Entomopathogenic Nematodes

The peachtree borer, Synanthedon exitiosa (Say 1823), is a major pest of stone fruit trees in North America. Current management relies upon preventative control using broad-spectrum chemical insecticides, primarily chlorpyrifos, applied in the late summer or early fall. However, due to missed applications, poor application timing, or other factors, high levels of S. exitiosa infestation may still occur and persist through the following spring. Curative treatments applied in the spring to
