Molecular and bioassay methods were used to characterize an isolate of Rotylenchulus reniformis collected from Fowa-Kafr-El-Sheihk, Egypt, and maintained for 40 years under greenhouse conditions. The identification of this isolate was rapidly determined b... see more

Seven needle nematode species of the genus Longidorus have been reported in Ukraine. Nematological surveys for needle nematodes were carried out in Ukraine between 2016 and 2017 and two nematode species of Longidorus ( L. caespiticola and L. poessneckensi... see more

The D2-D3 expansion segments of the 28S ribosomal RNA (rRNA) were sequenced and compared to predict secondary structures for Hoplolaiminae species based on free energy minimization and comparative sequence analysis. The free energy based prediction method... see more

DNA sequences of the D2-D3 expansion segments of the 28S gene of ribosomal DNA from 23 taxa of the subfamily Hoplolaiminae were obtained and aligned to infer phylogenetic relationships. The D2 and D3 expansion regions are G-C rich (59.2%), with up to 20.7... see more
