Characterization of Lilium longiflorum cv. ‘Nellie White’ Infection with Root-lesion Nematode Pratylenchus penetrans by Bright-field and Transmission Electron Microscopy

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

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

., 2018; Ruark et al., 2017, 2018). 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

The Mesostigmatid Mite Protogamasellus mica, an Effective Predator of Free-Living and Plant-Parasitic Nematodes

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

First report of Pratylenchus vulnus associated with apple in Tunisia

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

The morphological characteristics and phylogenetic analysis of Pratylenchus vulnus Taiwan strawberry isolate

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.

Nematicidal activity of fipronil against Pratylenchus zeae in sugarcane

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
