A description is provided of Longidorus cholevae sp. n., a bisexual species associated with wild cherry (Prunus avium L.) from the Rila Mountains, Bulgaria. The position of L. cholevae sp. n. among other species of the genus was elucidated by using morphological and molecular data. Phylogenetic analyses were performed of D2-D3 expansion domains of the 28S rRNA and the partial ITS1 containing re...

Dagger and needle nematodes included in the family Longidoridae (viz. Longidorus, Paralongidorus, and Xiphinema) are highly polyphagous plant-parasitic nematodes in wild and cultivated plants and some of them are plant-virus vectors (nepovirus). The mitochondrial (mt) genomes of the dagger and needle nematodes, Xiphinema rivesi, Xiphinema pachtaicum, Longidorus vineacola and Paralongidorus lito...

We describe and illustrate a new 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 a body length of 5.4-9.0 mm; lip region slightly swollen, anteriorly flattened, giving the anterior end a truncate ap...

Longidorus africanus multiplication on tomato was highest at 29 degrees C. Few nematodes were recovered after 6 weeks at soil temperatures of 35 degrees C or below 23 degrees C. The time to egg hatching was shortest and the percentage of eggs hatching was highest at 29 degrees C. The minimum temperature and the heat sum above this temperature required for egg development were calculated to be 1...

Longidorus elongatus (de Man) was always found in soil from patches in raspberry and strawberry plantations where the plants were infected with the beet ringspot (Scottish) strain of tomato black ring virus but rarely elsewhere in the same plantations. L. elongatus hand-picked from virus-containing field soil transmitted the virus to sugar beet, turnip, and spinach seedlings, but did so less of...

Summary Specimens of a thin longidorid species collected in Peñalba (Huesca), north-west Spain, were previously described as Paralongidorus iberis . However, we conclude, through scanning electron microscopy and molecular studies on population from about 15 km the type locality paratype specimens, that this was originally placed wrong genus. Both populations have pore-like amphidial apertures, ...

Molecular phylogeny of the nematode genus Longidorus (Nematoda: Longidoridae) with description of three new species Carlos Gutiérrez-Gutiérrez, Carolina Cantalapiedra-Navarrete, Miguel Montes-Borrego, Juan E.

The host range of Longidorus africanus was demonstrated to be much wider than previously reported. All commercial crop plants tested, except two of four crucifers, were hosts of L. africanus. The nematode was widespread in fields, and soil type did not appear to be related to its distribution. The minimum time to complete a life cycle was 9 weeks at 28 C in a plant growth chamber. Field observa...
