Lilium longiflorum cv. Nellie White, commonly known as Easter lily, is an important floral crop with an annual wholesale value of over $26 million in the United States. The root-lesion nematode, Pratylenchus penetrans, is a major pest of lily due to the significant root damage it causes. In this study, we investigated the cytological aspects of this plant–nematode interaction using bright-field and transmission electron microscopy. We took advantage of an in vitro culture method

We have recently discovered a new virus (the root lesion nematode virus, RLNV1) associated with the migratory nematode Pratylenchus penetrans (Vieira and Nemchinov, 2019). P. penetrans is an endoparasitic migratory PPN, which can infect a broad range of economically important crops (Castillo and Vovlas, 2007) and is among the top three most damaging species of PPN (Jones et al., 2013). Pratylenchus species were the most abundant PPN (69%) identified in 38,022

Vovlas, 2007). Molecular techniques as RAPD-PCR and sequencing of D2 to D3 expansion segments of the 28S rRNA was used for the identification of P. vulnus on different plant species (Subbotin et al., 2008; Bakooie et al., 2012; Lopez-Nicora et al., 2012). Moreover, real-time PCR provides sensitive identification of the species with species-specific primers using 1/128 of the DNA of one nematode (Huang and Yan, 2017).
Pratylenchus vulnus (Allen and Jensen, 1951) (walnut root lesion nematode) has been

includes approximately 100 valid species. Traditionally, identification of the species relies on morphology, morphometric and molecular methods (Gafur, 2020). So far, three root-lesion nematode species including P. neglectus, P. pseudopratensis and P. thornei have been isolated and reported from pistachio trees in Kerman, Qazvin, Qom, Yazd, and Fars provinces from Iran (Alvani et al., 2016). The aim of this work was to provide morphological, morphometrically and molecular characters of P. oleae from

Protogamasellus mica was extracted from a sugarcane field in Australia and cultured on bacterial-feeding nematodes. Studies with various nematodes in laboratory arenas showed that one mite and its progeny reduced nematode numbers by between 26 and 50 nematodes/day. A bacterivore (Mesorhabditis sp.), a fungivore (Aphelenchus avenae), and two plant parasites (root-knot nematode, Meloidogyne javanica and root-lesion nematode, Pratylenchus zeae) were all reduced at much the same rate despite the

The root-lesion nematode of the genus Pratylenchus Filipjev (1936) has a worldwide distribution and cause severe production constraints on numerous important crops. In 2013-14, during a survey of the apple nurseries and orchards in center of Tunisia (Kairouan, Zaghouan, Monastir and Kasserine), 70 different roots and soil samples were collected. The populations of root-lesion nematode were identified on the basis of their morphological and morphometric characters, and by molecular methods

resistance that is reliable and suitable for screening large numbers of progeny lines. The parameter(s) used to measure disease resistance needs be realistic and repeatable.
In Australia, the resistance of sugarcane accession lines is measured by determining the ability of the root-lesion nematode to reproduce in the roots of the test lines. The nematode reproduction is measured by the number of nematodes per plant at the harvest that has been inoculated with a certain number of nematodes at planting

discovery of the existence and population dynamics of P. vulnus in Taiwan implies a new threat to the 1,639 million NTD (ca. $52 million) strawberry industry. Currently, no nematicide is registered for root-lesion nematode suppression in strawberry. Related cultural and physical control options are currently undergoing evaluation by agricultural extension agencies to prevent serious damage.

losses were observed for both plant and ratoon crops due to the root-lesion nematode, Pratylenchus zeae (Kawanobe et al., 2014, 2016, 2019). Despite the very significant yield losses caused by the nematode, no nematicide has been registered for the control of plant-parasitic nematodes on sugarcane in Japan. Though alternative approaches to control plant-parasitic nematodes in sugarcane fields are available, such as antagonistic plants and crop rotation, nematicides may be an effective tool for
